[0001] The present application relates to the field of communication technology, and in particular to a time slot negotiation method, device, equipment and computer-readable storage medium. Background Art

[0002] In the field of communication technology, in the process of transmitting service data using a transmission channel between devices, multiple time slots can be further divided in the transmission channel, and data of different services can be transmitted through the time slots to improve the utilization rate of the transmission channel. Taking the transmission channel of Ethernet as an example, the information transmitted by the transmission channel of Ethernet can be a fine-grained basic unit (fg-BU). Among them, fg-BU is used to carry service data, and an fg-BU includes multiple time slots. Different time slots can encapsulate data of different services. The transmission of data of multiple services is achieved by transmitting fg-BU in the transmission channel. Therefore, a time slot negotiation method is needed to determine the time slot occupied by the data of the service through negotiation. Summary of the invention

[0003] The present application provides a time slot negotiation method, apparatus, device and computer-readable storage medium to determine the time slot occupied by service data through negotiation. The technical solution is as follows:

[0004] In a first aspect, a time slot negotiation method is provided, the method comprising: obtaining time slot negotiation results of N services, the time slot negotiation results are obtained through negotiation with a first device, the time slot negotiation result of any service indicates the time slot occupied by transmitting data of any service, wherein N is an integer greater than or equal to 2; sending a time slot effective notification to the first device, the time slot effective notification indicating that the time slot negotiation results of multiple services are effective. After negotiating the time slots occupied by the data of the N services, a time slot effective notification is sent, so that the time slot negotiation results of the N services are effective at the same time, thereby adjusting the time slots occupied by the data of the N services in parallel, with short negotiation time and high efficiency.

[0005] In a possible implementation, obtaining the time slot negotiation results of N services includes: negotiating with the first device to obtain the time slot negotiation results of each service according to the negotiation order of each service in the N services. The time slot negotiation results of the N services are obtained in sequence according to the negotiation order of the N services, and the process of obtaining the time slot negotiation results is highly organized.

[0006] In a possible implementation, obtaining the time slot negotiation results of N services includes: sending N time slot request sets to the first device, the N time slot request sets correspond to the N services one by one, a time slot request set includes at least one time slot negotiation request, and a time slot request set is used to negotiate with the first device the time slot occupied by the data of a service; receiving a time slot response set corresponding to the N services returned by the first device according to the N time slot request sets, a time slot response set includes at least one time slot negotiation response; determining the time slot negotiation results of the N services according to the time slot response sets corresponding to the N services. By sending and receiving the time slot request set and the time slot response set, the negotiation of the service time slot can be completed, and then the time slot negotiation result can be obtained, and the method for obtaining the time slot negotiation result is simple.

[0007] In a possible implementation, before obtaining the time slot negotiation results of the N services, the method further includes: sending a time slot negotiation notification to the first device, where the time slot negotiation notification indicates starting to negotiate the time slots occupied by the data of the N services. By sending the time slot negotiation notification, the first device knows that the time slot negotiation method for the N services different from the single service needs to be executed, unifies the execution method of the first device and the second device at the local end, and ensures that the first device and the second device execute the same set of time slot negotiation methods, so that the time slot negotiation is smoothly executed and the success rate is improved.

[0008] In a possible implementation, the time slot negotiation notification is carried in at least one of a flag field, a reserve (RES) field or a negotiation field in an overhead frame. The field type carried by the time slot negotiation notification is not limited, and the versatility is high.

[0009] In a possible implementation, the RES field is assigned a first value, and the first value is used to determine the number of services or time slots that need to be negotiated, where the number of time slots is the total number of time slots that need to be adjusted or the number of time slots that need to be adjusted for services corresponding to the overhead frame. The RES field can be used to identify the number of services or time slots that need to be negotiated, and then the number indicates that the time slots for N services are being negotiated, and the carrying method of the time slot negotiation notification is highly flexible.

By receiving the time slot increase adjustment notification sent by the first device to determine the time slot occupied by the data of any one of the services that can be increased, the start negotiation time for increasing the time slot is more accurate and has high precision. Since the time slot increase adjustment notification is sent by the first device located downstream based on the downstream time slot negotiation situation, triggering the negotiation to increase the time slot based on the time slot increase adjustment notification can reduce the impact of the increase in time slots on the transmission of service data, thereby avoiding service failures.

[0069] The terms used in the implementation method of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. In order to make the purpose, technical solution and advantages of this application clearer, the implementation method of this application will be further described in detail below with reference to the accompanying drawings.

[0070] In the process of transmitting service data by time division multiplexing (TDM), multiple time slots can be divided in the transmission channel between transmission devices, and the time slots can be used to transmit data of different services in the same transmission channel, thereby improving the utilization rate of the transmission channel. Taking the transmission channel of Ethernet as an example, the transmission channel can be sliced ​​into Ethernet to obtain a metro transport network (MTN) channel. An MTN channel can transmit multiple fg-BUs, and an fg-BU includes multiple time slots. Different time slots can encapsulate data of different services.

[0071] Figure 1 A schematic diagram of a fg-BU package provided in an embodiment of the present application, see Figure 1 A sub-slot is a time slot used to encapsulate service data in the embodiment of the present application. A sub-slot can carry 8 code blocks. The size of the code block is 66 bits (bit, b) or 65 bits after compression. Figure 1 Taking the code block of 65b as an example, 24 sub-slots are then added to the payload frame, and the overhead (OH) frame and the payload frame are filled in the D code block and the payload of the T7 code block of the fg-BU, to obtain the fg-BU including 24 sub-slots. Figure 1 This is intended to illustrate the structural relationship between time slots and fg-BUs, rather than to define the encapsulation process of fg-BUs. fg-BUs can be Figure 1 The package shown is obtained, and can also be obtained by other means.

[0072] Regardless of the method for obtaining fg-BU, the transmission device can encapsulate the data of the service in the sub-slot included in the fg-BU, and transmit the fg-BU to realize the transmission of the data of the service. Among them, the transmission device can transmit fg-BU alone, or it can form a multiframe with multiple fg-BUs, for example, 20 fg-BUs form a multiframe, and transmit the multiframe. The embodiment of the present application does not limit the channel bandwidth corresponding to the sub-slot. Taking the MTN channel with a transmission channel of 5 gigabits per second (Gbps) as an example, the bandwidth value of each sub-slot that can be used to carry the data of the service is 10 megabits per second (Mbps). The MTN channel can also be other values. For example, if the bandwidth size is 10Gbps, a larger number of sub-slots can be transmitted in an MTN channel, and the bandwidth of each sub-slot used to carry the data of the service is 10Mbps. In addition, the bandwidth of each sub-slot used to carry the data of the service can also be other values. Based on the situation where the data of the service needs to be carried through the time slot, the embodiment of the present application provides a time slot negotiation method for negotiating the time slots occupied by the data of N services.

[0073] Please refer to Figure 2 , which shows a schematic diagram of the implementation environment of the time slot negotiation method provided in an embodiment of the present application, and the implementation environment includes a first device 01 and a second device 02. A transmission channel is connected between the first device 01 and the second device 02, and the established connection can be established through a wired or wireless network. Among them, the first device 01 and the second device 02 are used to negotiate and obtain the time slot negotiation results of N services, and then the second device 02 sends a time slot effectiveness notification to the first device 01 to notify that the time slot negotiation results of the N services are effective.

[0074] Optionally, the first device 01 and the second device 02 are intended to distinguish between two transmission devices in the negotiation interaction, rather than to limit the operations performed by the transmission devices. In some cases, the first device 01 can also act as the second device 02 and perform operations involved by the second device 02. For example, Figure 1 There is also a transmission device connected downstream of the first device 01 in the method. After completing the time slot negotiation with the second device 02, the first device 01 will also negotiate the time slot with the transmission device located downstream. In this case, the first device 01 acts as the second device 02 and performs the operations involved by the second device 02 in the time slot negotiation method.

[0075] Exemplarily, the first device 01 and the second device 02 may be any network device with a data transmission function, such as a switch, a router, a gateway (GW), and a packet transport network (PTN) device, etc. In some cases, the functions of the first device 01 and the second device 02 are integrated on a chip configured in the network device.

[0076] The flowchart of the time slot negotiation method provided in the embodiment of the present application is as follows Figure 3 As shown, it includes S301-S303.

[0077] S301, the second device negotiates with the first device to obtain time slot negotiation results of N services, where the time slot negotiation result of any service indicates the time slot occupied by transmitting data of any service, and N is an integer greater than or equal to 2.

[0078] In one possible case, the second device obtains time slot adjustment instructions for N services, determines the time slots occupied by the data of the N services that need to be adjusted based on the time slot adjustment instructions, and starts negotiation with the first device. The process of obtaining the time slot negotiation instructions is, for example, that the second device receives the time slot adjustment instructions for the N services issued by the network management center. The network management center can send the time slot adjustment instructions for each of the N services separately, or it can encapsulate the time slot adjustment instructions for the N services together and send them to the second device. In addition, the device that issues the time slot adjustment instructions can be the network management center, or it can be other devices that manage data transmission, such as control devices.

[0079] After the second device obtains the time slot adjustment instructions for N services, it determines that it is necessary to start negotiating the time slots occupied by the data of the N services. In the case where the time slots occupied by the data of the N services that need to be adjusted are located in a transmission channel, the second device determines that it is necessary to perform N service negotiations. Since a single service negotiation or N service negotiations can be performed between the second device and the first device, and there is a difference between the negotiation process of the single service negotiation and the negotiation of N services. Therefore, the second device needs to send a time slot negotiation notification to the first device, and the time slot negotiation notification indicates the start of negotiation of the time slots occupied by the data of the N services. After the first device receives the time slot negotiation notification sent by the second device, it parses the received time slot negotiation notification and determines that the negotiation is a negotiation of N services that is different from a single service.

[0080] The embodiment of the present application does not limit the process of the second device sending the time slot negotiation notification to the first device. The sending of the time slot negotiation notification and the negotiation can be performed in series, that is, the second device first sends the time slot negotiation notification to the first device, and then negotiates with the first device. Figure 4 As shown, Figure 4In the example, the transmission process of the change request (CR) and the change answer (CA) indicates the negotiation process between the second device and the first device, see Figure 4 Before negotiating with the first device, the second device will send an independent time slot negotiation notification to the first device. The independent time slot negotiation notification can be carried in the overhead frame. For the carrying method of the overhead frame, see the following embodiment.

[0081] Optionally, sending the time slot negotiation notification and the negotiation can also be performed in parallel, that is, the second device completes the sending of the time slot negotiation notification during the negotiation with the first device, for example, carrying the time slot negotiation notification in the overhead frame transmitted during the time slot negotiation. In one possible implementation, the time slot negotiation notification can be carried in at least one of the flag field, the reserved (RES) field and the negotiation field in the overhead frame. In the case where multiple overhead frames need to be transmitted for time slot negotiation, the overhead frame carrying the time slot negotiation can be one of them, or part of the overhead frames, or all of the overhead frames.

[0082] The overhead frame is a field included in the fg-BU, and the second device and the first device can achieve negotiation by transmitting the overhead frame. Figure 5 A schematic diagram of the structure of a fg-BU provided in the embodiment of the present application is shown in FIG. Figure 5 , fg-BU includes overhead (OH) frame and payload frame. Figure 5 The structure of the overhead frame in Figure 6 , Figure 5 The overhead frame in the MAC address includes a flag field and three RES fields, the three RES fields are the RES field before the multi-frame indication (MFI) field, the RES field after the flag field, and the RES field before the cyclic redundancy check (CRC). Optionally, the overhead frame also includes a negotiation field, such as Figure 6 For the meaning of each negotiation field, please refer to the relevant description in the following embodiments, which will not be repeated here.

[0083] The second device may select at least one of the flag field, the RES field, and the negotiation field in the overhead frame to carry the timeslot negotiation notification in the overhead frame. Figure 6 In the first overhead frame shown in (1) of FIG. 1 , the second device assigns the flag field a value of 0b01 to indicate that N service negotiations are to be performed. Figure 6In the second overhead frame shown in (2), the second device assigns the flag field to 0b10 to indicate N service negotiations. In one possible case, one fine-grained client corresponds to one service, and the N service negotiations may refer to multi-fine grained client (multi-fg client) negotiations. Optionally, when the flag field is assigned to 0b01 or 0b10, in addition to being used to indicate N service negotiations, it can also be used to indicate that the 33-bit position after CA includes a fine-grained client identity document (fg client id) field, a fine-grained slot (fg slot) field, and a RES field.

[0084] In some cases, you can also Figure 6 In the third overhead frame shown in (3) of FIG. 1 , the second device assigns a value of 1 to the RES field, indicating that N services are being negotiated, and assigns a value of 0 to the RES field, indicating that a single service is being negotiated. Correspondingly, the second device may also choose to assign a value of 0 to the RES field, indicating that N services are being negotiated, and assign a value of 1 to the RES field, indicating that a single service is being negotiated. The assigned RES field may be the RES field before the CRC field, or may be the RES field before the CRC field. Figure 6 For example, when the RES field is assigned a value indicating N service negotiations, the flag field may be assigned a value as follows: Figure 6 The third overhead frame shown in (3) is assigned a value of 00, indicating that the 33-bit position after CA includes the fg client id field, the fgslot field, and the RES field, or the flag field is assigned a value of another value. In addition, the second device can also assign a value to the S bit, the C bit, the CR bit, and the CA bit in combination to indicate N service negotiations. Alternatively, different fields can be combined and assigned values ​​to different fields to obtain a time slot negotiation notification indicating N service negotiations.

[0085] Optionally, the time slot negotiation notification can be as shown in the above example, used to indicate that N services need to be negotiated, or it can indicate the number in the negotiation process to indicate that the services for time slot negotiation are N services different from a single service, and the number is, for example, the number of services or the number of time slots. For example, the second device assigns the RES field to a first value, and the first value is used to determine the number of services or the number of time slots that need to be negotiated. Among them, the RES field assigned by the second device can be the RES field before the CRC field, or it can be a RES field at other locations. The number of time slots is the total number of time slots that need to be adjusted or the number of time slots that need to be adjusted for the service corresponding to the overhead frame. The total number of time slots is the sum of the number of time slots that need to be adjusted for each service in the N services.

[0086] Taking the first value as a positive integer M as an example, the RES field before the CRC field is assigned a value of M, indicating that the number of services participating in this negotiation is 2 M For example, if M is equal to 9, the RES field indicates that the number of services is 512. Alternatively, the RES field is set to the binary form of N to indicate the number of services that need to be negotiated, where N is a positive integer greater than or equal to 2. When the size of the RES field is 9 bits, the value range of the number that can be represented is 0 to 511.

[0087] In addition, the RES field assigned by the second device may be one RES field or multiple RES fields. Figure 6 The RES field after the flag field is set to 0, indicating that the number of time slots indicated by the RES field before the CRC field is the total number of time slots. Figure 6 The RES field after the flag field is assigned a value of 1, indicating that the number of time slots indicated by the RES field before the CRC field is the number of time slots that need to be adjusted for the service corresponding to the overhead frame. The service corresponding to the overhead frame refers to the time slot occupied by the data of the service adjusted by the overhead frame. In some cases, the service corresponding to the overhead frame can be identified by the fg client id.

[0088] The time slot negotiation notification may choose to indicate that only N service negotiations are required, or may choose to indicate only the number of time slots being negotiated, or may further indicate the number of time slots being negotiated on the basis of indicating N service negotiations. For example, the flag field is assigned a value of 0b10 to indicate that N service negotiations are being performed, and then the RES field before the CRC field is assigned a value as shown in the above embodiment to indicate the total number of time slots that need to be negotiated.

[0089] Since the overhead frame is the data that needs to be transmitted during the negotiation process, the time slot negotiation notification is carried in the overhead frame transmitted during the time slot negotiation process, so that the first device is synchronously notified to perform N service negotiations during the negotiation process. Next, the process of the second device and the first device negotiating to obtain the time slot negotiation results of N services is described, and the role of the overhead frame in the negotiation process is described.

[0090] Exemplarily, the second device and the first device negotiate to obtain the time slot negotiation results of N services, including: the second device sends N time slot request sets to the first device, the N time slot request sets correspond one-to-one to the N services, one time slot request set includes at least one time slot negotiation request, and one time slot request set is used to negotiate with the first device about the time slot occupied by the data of a service; the first device receives the N time slot request sets sent by the second device, adjusts the time slot table of each of the N services according to the received N time slot request sets, determines the time slot negotiation results of the N services according to the adjustment results of the time slot tables of each service, and sends the time slot response set corresponding to the N services to the second device according to the adjustment results of the time slot tables of each service, the time slot response set corresponding to the N services indicates whether the negotiation is successful; the second device receives the time slot response set corresponding to the N services returned by the first device according to the N time slot request sets, and determines the time slot negotiation results of the N services according to the time slot response set corresponding to the N services.

[0091] For the N time slot request sets and the time slot response sets corresponding to the N services involved in the negotiation process, the second device and the first device may transmit the N time slot request sets and the time slot response sets corresponding to the N services through including but not limited to the following two negotiation methods.

[0092] Negotiation mode 1: The second device negotiates with the first device respectively according to the negotiation order of each service in the N services to obtain the time slot negotiation result of each service.

[0093] Optionally, the negotiation order of each service may be a priority order of each service, and the priority order may be determined according to the service level agreement (SLA) of the service. For example, the transmission delay indicated by the SLA of a gaming service is lower than the transmission delay indicated by the SLA of a video service, and the second device determines that the priority of the gaming service is higher than the priority of the video service. The negotiation order of the services may also be the order in which the time slot adjustment instructions of the services are obtained. For example, after receiving the time slot adjustment instruction of service A, the second device receives the time slot adjustment instruction of service B, thereby determining that the negotiation order of service A precedes the negotiation order of service B. The negotiation order of each service may also be a random order.

[0094] Regardless of the circumstances under which the negotiation order of each service is obtained, the second device will negotiate each service in series according to the negotiation order. Since the negotiation process of different numbers of services is similar, the following embodiment of the present application takes N equal to 2 as an example to illustrate the process of negotiating the time slots occupied by the data of N services. Taking the two services that need to be negotiated as service A and service B, and the negotiation order of service A precedes the negotiation order of service B as an example, the first device and the second device negotiate service A and service B in series, which means that the first device and the second device first negotiate the time slot occupied by the data of service A, and when the negotiation of service A is completed, negotiate the time slot occupied by the data of service B.

[0095] Optionally, the process of negotiating any service between the second device and the first device includes: the second device sends a time slot request set corresponding to any service to the first device; the first device adjusts the time slot table of any service according to the received time slot request set corresponding to any service, and returns a time slot response set corresponding to any service to the second device according to the adjustment result of the time slot table; the second device determines the time slot negotiation result of any service according to the time slot response set corresponding to any service.

[0096] Exemplarily, any service may request to adjust one time slot or multiple time slots. In the case of requesting to adjust multiple time slots, one time slot negotiation request may be used to negotiate with the first device to adjust one time slot, that is, the time slot request set of any service includes multiple time slot negotiation requests, and the time slot negotiation requests correspond to the time slots to be adjusted one by one. One time slot negotiation request may also be used to negotiate with the first device to adjust multiple time slots, that is, the time slot request set of any service includes one time slot negotiation request.

[0097] Regardless of the time slot negotiation request included in the time slot request set, the encapsulation method of the time slot negotiation request is similar. Optionally, the time slot negotiation request is carried in the negotiation field of the overhead frame. Figure 6 Taking the structure of the overhead frame shown as an example, the time slot negotiation request is carried in the CR bit. The second device can assign the CR bit in the overhead frame to a second value to obtain the time slot negotiation request. The second value indicates that the bit is effective. The second value is, for example, 1, or other values. By assigning the CR bit in the negotiation field to the second value and other negotiation fields to the third value, the time slot negotiation request is carried in the overhead frame, where the other negotiation fields refer to the fields in the negotiation field other than CR, for example Figure 6 In the S field, C field and CA field, the third value indicates that the bit is not valid, and the third value is 0, for example.

[0098] In addition, the time slot negotiation request corresponding to any service may also include the time slot that needs to be adjusted and the action to be taken on the time slot. Figure 6The fg slot field in is used to identify the time slot that needs to be adjusted. The fg client id can further identify the action on the time slot when indicating the service corresponding to the time slot negotiation request. The following example illustrates the way in which the fg client id identifies the action. When the bit used to identify the action in the fg client id is assigned a value of 0, the action indicated is release. When the bit used to identify the action in the fg client id is assigned a value of 1, the action indicated is occupation.

[0099] In one possible case, the time slot negotiation request corresponding to any service may include the time slot that needs to be adjusted. For example, the fg slot field is used to identify the time slot that needs to be adjusted, and the fg client id field is only used to identify the service corresponding to the time slot negotiation request. Among them, the service corresponding to the time slot negotiation request refers to the time slot requested for negotiation by the time slot negotiation request, which is the time slot occupied by the data of the service. For example, time slot negotiation request A is used to negotiate with the first device to add time slot A for service A to transmit the data of service A, then the service corresponding to time slot negotiation request A is service A. Alternatively, time slot negotiation request B is used to negotiate with the first device to release time slot B occupied by the data of service A, then the service corresponding to time slot negotiation request B is service A. By assigning the fields in the overhead frame, the acquisition of the time slot negotiation request can be achieved without adjusting the structure of the overhead frame. After assigning the overhead frame, the second device can send the assigned overhead frame to the first device to send a time slot request set including the time slot negotiation request.

[0100] After the first device receives the time slot request set corresponding to any service, it can determine the time slot negotiation result of any service according to the time slot request set. The processing process includes: determining the time slot adjustment strategy of any service according to the time slot request set corresponding to any service; adjusting the time slot table of any service according to the time slot adjustment strategy of any service; and sending the time slot response set corresponding to any service to the second device according to the adjustment result of the time slot table of any service.

[0101] The first device parses the time slot negotiation request included in the time slot request set corresponding to any service, and obtains the time slot adjustment strategy of any service. Taking any service as service A as an example, the first device determines that the time slot requested for adjustment is time slot A according to the fg slot field in the overhead frame. Since the fg client id includes multiple bits, at least one bit of the multiple bits can be used to identify the service, and thus the first device can determine that the service corresponding to the overhead frame is service A according to the value of the bit used by the fg client id to identify the service. There is also at least one bit in the multiple bits used to identify the action. For example, when the bit used by the fg client id to identify the action is assigned to 0, the first device can determine that the requested action is release according to the value of the bit used to identify the action being 0, and the first device thus determines that the time slot adjustment strategy of service A is to release time slot A. Afterwards, the first device obtains the time slot table of service A, which stores the time slots occupied by the data of service A. The first device deletes the information of time slot A from the time slot table of service A based on the adjustment strategy, and completes the adjustment of the time slot table of service A.

[0102] In one possible case, when the time slot negotiation request does not indicate an action to be performed on the time slot, the first device can determine the time slot adjustment strategy in combination with the time slot table of any service. Continuing to take the example of determining that the time slot requested for adjustment is time slot A according to the fg slot field, since the time slots occupied by the data indicating service A in the time slot table are time slot A, time slot B, time slot C and time slot D, including the time slot A requested for adjustment, the first device thus determines that the action to be performed on the occupied time slot A is release, and the time slot adjustment strategy of service A is release time slot A. Taking the example of determining that the time slot to be adjusted is time slot E according to the fg slot field, since the time slots occupied by the data indicating service A in the time slot table do not include the time slot E requested for adjustment, the first device thus determines that the time slot adjustment strategy of service A is to occupy time slot E. The first device adds the information of time slot E in the time slot table based on the adjustment strategy, and completes the adjustment of the time slot table of service A.

[0103] After the first device finishes adjusting the time slot table of any service, it determines the time slot negotiation result according to the adjustment result of the time slot table. Taking the time slots of service A requested for adjustment as occupied time slot E and released time slot A as an example, the first device determines the time slot adjustment result of service A as reducing occupied time slot A and increasing occupied time slot E according to the adjustment result of the time slot table.

[0104] In addition, the first device will also send a time slot response set corresponding to any service to the second device according to the adjustment result of the time slot table of any service, and the time slot response set includes at least one time slot negotiation response. Similar to the case of the time slot negotiation request included in the time slot request set, in the case where any service needs to adjust multiple time slots, the time slot response set may include a time slot negotiation response, and the adjustment status of multiple time slots of the service is notified through the time slot negotiation response. The time slot response set may also include multiple time slot negotiation responses, that is, the time slot negotiation responses and the time slots that need to be adjusted correspond one to one.

[0105] Optionally, the time slot negotiation response can be carried in the overhead frame in a manner similar to that of the time slot negotiation request, except that the negotiation field assigned to the time slot negotiation response is the CA bit. The first device can assign values ​​to the received overhead frame, assign the CA bit to the second value, and assign the CR bit to the third value, so as to carry the time slot negotiation response in the overhead frame. Furthermore, in the case where the time slot negotiation notification is carried in the overhead frame, the first device can choose to retain the carried time slot negotiation notification, or can choose to reset the field carrying the time slot negotiation notification to the initial value. In addition, the first device can also choose to assign the CA bit in the new overhead frame to obtain the time slot negotiation response.

[0106] Regardless of the method used to assign the time slot negotiation response, whether the negotiation is successful can be indicated by sending the time slot negotiation response. For example, by assigning a value to any RES field in the overhead frame carrying the time slot negotiation response, the RES field can be assigned to indicate whether the negotiation is successful or failed. In the case where the first device successfully adjusts the time slot table of any service, the time slot negotiation response indicates a successful negotiation. In the case where the first device fails to successfully adjust the time slot table of any service, the time slot negotiation response indicates a failed negotiation. For example, the second device requests to add time slot F to service A, and the first device queries the time slot table to determine that time slot F is occupied by the data of service B. Based on this, the first device fails to add the information of time slot F to the time slot table of service A, fails to successfully adjust the time slot table of service A, and the time slot negotiation response corresponding to time slot F indicates a failed negotiation.

[0107] Optionally, the first device may also choose to return a time slot negotiation response if the negotiation is successful, and not return a time slot negotiation response if the negotiation fails. The first device temporarily stores the time slot adjustment strategy, and after the first time length, re-adjusts the time slot table of any service according to the time slot adjustment strategy, determines the time slot negotiation result according to the adjustment result of the time slot table, and returns a time slot response set. Among them, the first time length can be a fixed time length set according to experience, or it can be the time length of the time slot request set corresponding to N services received. Since the state of the time slot corresponding to the time slot adjustment strategy may change within the first time length, the time slot adjustment strategy that failed to adjust before may be able to adjust successfully. Continuing with the request to add time slot F as an example, since the time slot adjustment strategy of service B includes releasing time slot F, after the first time length, the first device determines that the state of time slot F changes from occupied to unoccupied, and the first device adds the information of time slot F in the time slot table of service A to adjust time slot F, and returns the time slot negotiation response corresponding to time slot F to the second device.

[0108] Alternatively, in the event of a negotiation failure, the first device first returns a time slot negotiation response indicating the negotiation failure to the second device, and temporarily stores the time slot adjustment strategy for the negotiation failure. During other time slot negotiations, the first device renegotiates according to the time slot adjustment strategy. If the negotiation is successful, the first device returns a time slot negotiation response indicating a successful negotiation, and the second device thereby updates the time slot negotiation result for the time slot.

[0109] Regardless of the method by which the first device returns the time slot negotiation response corresponding to any service to the second device, the second device will determine the time slot negotiation result for any service based on the received time slot negotiation response corresponding to any service after receiving the time slot negotiation response corresponding to any service. Taking the time slots adjusted by the data request of service A as an example, the second device only receives the time slot negotiation response for releasing time slot A, but does not receive the time slot negotiation response for occupying time slot F. According to the received time slot negotiation response, it is determined that the negotiation for occupying time slot F fails, and the negotiation for releasing time slot A succeeds. The second device determines that the time slot negotiation result of service A reduces the occupied time slot A.

[0110] After the negotiation of service A is finished, the second device starts to negotiate the time slot occupied by the data of service B. The embodiment of the present application does not limit the way in which the second device determines the end of the time slot negotiation of service A. The second device can determine the end of the time slot negotiation of service A after obtaining the time slot response set corresponding to service A. The second device can also determine the end of the time slot negotiation of service A after the time length from sending the time slot request set of service A reaches the second time length. Among them, the second time length is an arbitrary time value set based on experience, for example, the second time length is set to one second based on experience. In this case, even if the time slot response set corresponding to service A is not received, the second device will determine that the negotiation of service A is over. By setting the second time length, even if the first device fails to adjust the time slot table of service A and does not return the time slot response set corresponding to service A, for example, the first device chooses to execute the operation of not sending the time slot response set to the second device in the above embodiment for the case of unsuccessful adjustment of the time slot table, the second device will not delay the start of the negotiation of service B because of waiting for the time slot response set corresponding to service A. The negotiation process of service B is similar to the negotiation process of service A, and the relevant description can be referred to, and it will not be repeated here.

[0111] Negotiation mode 2: the second device directly sends a set of time slot requests corresponding to each service to the first device.

[0112] Optionally, the second device may also directly send a set of time slot requests corresponding to each service to the first device, and the first device determines the time slot negotiation results of the N services based on the received N time slot request sets, and returns a set of time slot responses corresponding to the N services. Exemplarily, the first device determines the time slot adjustment strategy for each service based on the N time slot request sets; adjusts the time slot table for each service based on the time slot adjustment strategy for each service. After adjusting the time slot table for each service, the first device sends a set of time slot responses corresponding to the N services to the second device based on the adjustment result of the time slot table for each service. The time slot tables for each service may be different time slot tables, or they may be combined in one table.

[0113] Among them, the process in which the second device sends N time slot request sets and the first device returns a time slot response set is similar to the process in which the second device sends a time slot request set for any service and the first device returns a time slot response set corresponding to any service in negotiation mode 1. The difference is that the second device does not need to wait for the negotiation of the previous service to end, that is, it may send a time slot request set corresponding to the next service to the first device. In addition, the first device can choose to return a time slot response set corresponding to any service after adjusting the time slot table of any service, that is, the first device returns N time slot response sets, and the time slot response set and the service are in a one-to-one correspondence. The first device can also choose to send a time slot response set to the second device after adjusting the time slot table of N services, that is, N services correspond to one time slot response set, and the time slot response set includes at least one time slot negotiation response, which is used to indicate whether the N services are negotiated successfully, for example, sending a time slot negotiation response to indicate the service that has been negotiated successfully, or sending two time slot negotiation responses, one for identifying the time slot that has been negotiated successfully and the other for identifying the time slot that has failed to negotiate, or sending N time slot negotiation responses, and one time slot negotiation response is used to identify the negotiation result of a service.

[0114] The first device and the second device can choose to use any one of negotiation mode 1 or negotiation mode 2 to complete the negotiation of the time slots occupied by the data of N services, and the embodiment of the present application does not limit this. In addition, the embodiment of the present application does not limit the negotiation type, and the time slot negotiation result of any service among the N services indicates that the data of any service increases the time slot occupied, or the data of any service reduces the time slot occupied, or the data of any service replaces the time slot occupied.

[0115] Optionally, when the time slot negotiation result of any service among N services indicates that the time slot occupied by the data of any service is increased, the first device will send a time slot increase adjustment notification corresponding to any service to the second device, and the time slot increase adjustment notification indicates that the second device is allowed to negotiate to increase the time slot occupied by the data of any service. Based on the reception of the time slot increase adjustment notification, the second device sends a time slot request set to the first device.

[0116] Figure 7 A schematic diagram of a time slot negotiation process provided in an embodiment of the present application, Figure 7 FIG. 2 shows a process in which the second device and the first device adopt negotiation mode 1, and the negotiated N services are service A and service B, and the second device and the first device negotiate in series to increase the time slots occupied by the data of service A and service B. FIG. Figure 7 In the figure, transmission device 1 is the second device, transmission device 2 is the first device, and the data transmission direction of service A and service B is from transmission device 1 to transmission device i+1, where i is a positive integer greater than 3.

[0117] Since the time slots occupied by the data of services A and B in the transmission channel are increased, the amount of data of services A and B transmitted per unit time in the transmission channel will increase. Therefore, the time slot negotiation direction is opposite to the data transmission direction, starting from the downstream channel to the upstream channel. First increase the time slots of services A and B in the downstream channel. Even if the upstream channel has not increased the time slots, the amount of data that can be transmitted by the upstream channel per unit time is less than the amount of data that can be transmitted by the downstream channel per unit time. There will be no situation where the amount of data exceeds the channel transmission capacity, and the service performance will not be affected by the time slot adjustment.

[0118] Since the first device is located downstream of the second device, after the first device successfully negotiates with the downstream transmission device 3 to increase the time slots occupied by the data of services A and B, it sends the time slot increase adjustment notification corresponding to services A and B to the first device, and the second device receives the time slot increase adjustment notification corresponding to services A and B sent by the first device, thereby determining that it can start to increase the time slots occupied by the data of services A and B. Optionally, the first device and the second device can choose to transmit the time slot increase adjustment notification when it is necessary to increase the time slot to trigger the time slot negotiation. The first device and the second device can also selectively trigger the time slot negotiation by transmitting the time slot increase adjustment notification according to the topological structure of the corresponding transmission channel. The corresponding transmission channel refers to the channel used by the first device and the second device to transmit the data of the service. For example, there are no other devices on the transmission channel corresponding to the first device and the second device, and the second device can directly negotiate with the first device to increase the time slot occupied by the data of the service without waiting for the time slot increase adjustment notification sent by the first device.

[0119] In addition, the time slot increase adjustment notification may also be carried in the overhead frame, and the first device assigns the S bit in the overhead frame to the second value, so as to carry the time slot increase adjustment notification in the overhead frame. The first device may also assign the fg client id field in the overhead frame to indicate the service corresponding to the time slot increase adjustment notification. The time slot increase adjustment notifications corresponding to different services may be one or more. For example Figure 7 In the example, the time slot increase adjustment notification corresponding to service A and service B is the same, the first device sends a time slot increase adjustment notification to the second device, and the second device determines that it can start to increase the time slots occupied by the data of service A and service B by parsing the fgclient id field in the overhead frame. In the case where the time slot negotiation notification needs to be transmitted separately before the time slot negotiation, the second device sends the time slot negotiation notification to the first device after receiving the time slot increase adjustment notification.

[0120] In the case where the time slot negotiation result indicates that the time slot occupied by the data of any service is changed, any service corresponds to two time slot request sets, namely, a request release set for requesting to release the time slot, and a request occupation set for requesting to occupy the time slot. Correspondingly, any service also corresponds to two response release sets, namely, a response release set for responding to release the time slot, and a response occupation set for responding to occupy the time slot. Optionally, the request release set corresponding to any service is sent in an order prior to the request occupation set.

[0121] Taking the request to change time slot A of service A to time slot F and the request to change time slot F of service B to time slot A as an example, the second device and the first device can choose according to Figure 8 The three transmission sequences shown negotiate service A and service B. Figure 8 In the figure, CR1 indicates the request release set corresponding to service A, CR2 indicates the request occupation set corresponding to service A, CR3 indicates the request release set corresponding to service B, CR4 indicates the request occupation set corresponding to service B, CA1 indicates the response release set corresponding to service A, CA2 indicates the response occupation set corresponding to service A, CA3 indicates the response release set corresponding to service B, and CA4 indicates the response occupation set corresponding to service B. Figure 8 The first transmission order from left to right is a process of serial negotiation according to the negotiation order of each service. The second device starts to send the next time slot request set only after receiving the time slot response set returned by the first device.

[0122] Figure 8 The second transmission order is to directly send a time slot request set of multiple services, and the first device adjusts the time slot table of each service according to the received multiple time slot request sets, and returns a time slot response set corresponding to each service. Figure 8 The third transmission order is to first negotiate the time slot release, and after the negotiation of the release of each service time slot is completed, start negotiating the time slot occupancy.

[0123] By changing the time slots occupied by data of multiple services through parallel negotiation, there is no need to use idle time slots for relocation, and time slot exchange between different services can also be achieved. Fig. 9 As shown, although the time slot F requested to be occupied by service A is occupied by the data of service B, during the negotiation of service A, the second device and the first device simultaneously negotiated service B, and service B requested to release time slot F and requested to occupy time slot A released by service A. Based on this, the first device determines that the data of service A can occupy time slot F, and the data of service B can occupy time slot A, thereby realizing the time slot exchange of service A and service B. Fig. 9In the figure, the blank circle and the shaded circle are used to distinguish the time slots occupied by service A and service B. In addition, the direction of negotiating the time slot change is consistent with the direction of data transmission, that is, the negotiation is from the upstream channel to the downstream channel.

[0124] For negotiating to reduce the time slot occupied by service data, the negotiation process is as follows: Fig.10 As shown in the figure, since reducing the time slot occupied by any service will not increase the amount of data of any service transmitted by the transmission channel per unit time, the direction of negotiation reduction is consistent with the direction of data transmission, that is, negotiation from the upstream channel to the downstream channel. By negotiating from the upstream channel, the amount of data transmitted by the upstream channel per unit time is controlled to be smaller than the amount of data transmitted by the downstream channel per unit time, thus avoiding data transmission exceeding the channel load capacity, thereby reducing the probability of packet loss.

[0125] Optionally, the negotiation type of each of the N services may be the same, for example, both service A and service B are used to request to increase the time slot occupied by data. The negotiation type of each service may also be different, for example, service A requests to increase the time slot occupied by data, and service B requests to change the time slot occupied by data.

[0126] In one possible case, during the negotiation with the first device, the second device will also count the number of time slot negotiation results obtained. When the number of counted time slot negotiation results is the same as the number of services, it is determined that the time slot negotiation results of N services have been obtained, thereby determining that the negotiation of N services is completed.

[0127] S302: The second device sends a time slot validation notification to the first device, where the time slot validation notification indicates that the time slot negotiation results of N services are effective.

[0128] After determining that the time slot negotiation of the N services is completed, the second device sends a time slot validity notification to the first device. In one possible case, the time slot validity notification is carried in at least one of the flag field, RES field, or negotiation field in the overhead frame. The second device obtains the time slot validity notification by assigning the C bit in the overhead frame, and sends the time slot validity notification to the first device. For example Figure 4 , Figure 7 , Figure 8 and Fig.10 As shown, C in the figure represents a time slot validity notification. The second device sends a time slot validity notification to the first device, indicating that the time slot negotiation results of N services are valid.

[0129] Optionally, the second device may also carry indication information of N services in the time slot effective notification, thereby identifying the effective time slot negotiation result as N service negotiations. That is, the flag field in the time slot effective notification may be 0b10 or 0b01, or the RES field before the CRC field may be 1 or M. In some cases, the time slot effective notification may also include a service identifier of each service, and the service identifier may be fg client id. For a detailed description, please refer to the description of the time slot negotiation notification in S301, which will not be repeated here.

[0130] S303: The first device receives a time slot validation notification sent by the second device, where the time slot validation notification indicates that the time slot negotiation results of N services are effective.

[0131] The first device parses the received time slot effective notification, thereby determining that the time slot negotiation results of N services are effective. Since the first device received the time slot negotiation notification indicating the negotiation of N services sent by the second device before starting the negotiation, the first device can determine that the negotiation is effective through a time slot effective notification. Therefore, after receiving the time slot effective notification, the first device determines that the time slot effective notification indicates that the time slot negotiation results of N services are effective. For example, the first device reads the fg client id field in the overhead frame carrying the time slot effective notification to determine the N services that are effective.

[0132] The first device determines that the time slot negotiation results of N services are effective, and the data of N services can be transmitted subsequently according to the time slot negotiation results. For example, the second device sends an fg-BU to the first device, and the second device determines, based on the adjusted time slot table, that time slot A in the received fg-BU carries data for service B, and time slots B, C, and D carry data for service A. The second device thus obtains data for service B and service A, and transmits data for service A and service B.

[0133] In summary, in the time slot negotiation method provided by the embodiment of the present application, after the first device negotiates the time slots occupied by the data of N services, it sends a time slot effectiveness notification, so that the time slot negotiation results of the N services are effective at the same time, thereby adjusting the time slots occupied by the data of the N services in parallel, and the negotiation time is short and the efficiency is high. In addition, since the time slot negotiation of the N services is performed simultaneously, different services do not need to borrow idle time slots for maneuvering, and time slots can be exchanged. The time slot exchange process is simple. Even if there are no idle time slots in the transmission channel, time slot exchanges between different services can be achieved, and the applicability is stronger. By extending the meaning of the original fields in the overhead frame, N service negotiations can be achieved without changing the structure of the overhead frame. The implementation method is simple and the implementation cost is low.
