[0003] This application relates to the field of optical communication technology, and in particular to a method, apparatus, computer device, and storage medium for determining optical slices. Background Technology

[0004] The current standard defines PON (Passive Optical Network) slicing in three granularities: OLT (Optical Line Terminal)-PON board granularity, OLT-PON port granularity, and ONU (Optical Network Unit) granularity. However, the standard provides more comprehensive definitions and descriptions for OLT-PON board granular slicing and OLT-PON port granular slicing, while the definition and description of ONU granular slicing are very limited. As a result, in practical applications, OLT-PON board granular slicing and OLT-PON port granular slicing are mainly used.

[0005] Therefore, it is essential to study methods for implementing ONU granular slicing, and methods for adjusting / configuring end-to-end slices resulting from ONU downlink port adjustments. Summary of the Invention

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] The slice determination method provided in this application embodiment can be applied to the application environment shown in Figure 1. The terminal 102 communicates with the server 104 via a network. A data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104 or placed on a cloud or other network server. The method involves obtaining the first resource slice of the first downstream port and the first service slice corresponding to the terminal; then, based on the first resource slice and the first service slice, determining the slice information corresponding to the terminal. The terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented using a standalone server or a server cluster composed of multiple servers.

[0042] In one embodiment, as shown in FIG2, a slice determination method is provided. Taking the application of this method to terminal 102 in FIG1 as an example, the method may include the following steps S201 to S203.

[0043] S201: When the terminal accesses the first downlink port among the downlink ports of the first optical network unit, obtain the first resource slice of the first downlink port.

[0044] It should be noted that, to ensure the timeliness of obtaining the first resource slice of the first downlink port, the candidate resource slices corresponding to each downlink port of the first optical network unit can be determined in advance. Then, when it is necessary to determine the resource slice corresponding to the first downlink port, the first resource slice of the first downlink port can be determined from the candidate resource slices corresponding to each downlink port.

[0045] In one embodiment of this application, a storage unit can be pre-set to record candidate resource slices corresponding to each downlink port of the first optical network unit. When it is necessary to determine the first resource slice of the first downlink port, the storage unit can be searched according to the label of the first downlink port. If the downlink port label corresponding to a candidate resource slice is the same as the label of the first downlink port, then the candidate resource slice is taken as the first resource slice of the first downlink port.

[0046] The resource slices are assigned to their respective resource slices D-NetX (X = 0, 1, 2, 3, 4, 5, 6, 7, 8) according to their physical identifiers (e.g., ONU-SN (ONU Serial Number) or ONU-MAC address).

[0047] To further explain, when it is necessary to determine the candidate resource slices corresponding to each downlink port of the first optical network unit, the resource slices can be matched according to the ONU-SN or ONU-MAC address of each downlink port, and identified as D-NetX (X=0,1,2,3,4,5,6,7,8).

[0048] Specifically, to determine whether D-NetX is suitable for this ONU, calculations and analysis need to be performed based on two given conditions. These two conditions are as follows:

[0049] Condition (I)D-NetX-max(ONU)≥D-NetX-online(ONU);

[0050] Condition (II) D-NetX-max(PON-Bandwidth)≥∑D-NetX-max(ONUx-Bandwidth) (where X=1,2,3,...,n).

[0051] Condition (I) ensures that the maximum bandwidth capacity (D-NetX-max(ONU)) provided by the D-NetX network for the ONU is not less than the bandwidth required for the ONU to be currently online (D-NetX-online(ONU)). Condition (II) ensures that the maximum bandwidth capacity (D-NetX-max(PON-Bandwidth)) provided by the D-NetX network for the entire Passive Optical Network (PON) is not less than the sum of the maximum bandwidths required by each of the ONUs (ONU1, ONU2, ..., ONUn).

[0052] As an example, (1) Collect data: obtain the value of D-NetX-max(ONU), obtain the value of D-NetX-online(ONU), obtain the value of D-NetX-max(ONUx-Bandwidth) for each ONU, and calculate their sum, obtain the value of D-NetX-max(PON-Bandwidth); (2) Compare condition (I): check whether D-NetX-max(ONU) is greater than or equal to D-NetX-online(ONU); (3) Compare condition (II): calculate the sum of the maximum bandwidth required by all ONUs ∑D-NetX-max(ONUx-Bandwidth), and check whether D-NetX-max(PON-Bandwidth) is greater than or equal to this sum; (4) Draw a conclusion: if both conditions are met, then D-NetX is suitable for the existence of this ONU.

[0053] S202: Determine the first service slice corresponding to the terminal based on the service information corresponding to the terminal.

[0054] It should be noted that when it is necessary to determine the first service slice corresponding to the terminal, the service information corresponding to the terminal can be obtained in advance, and then compared with at least one candidate service slice one by one according to the service information. If the service content corresponding to a certain candidate service slice is the same as the service information, then the candidate service slice is taken as the first service slice corresponding to the terminal.

[0055] The business information includes at least one of the following: identifier, destination Internet Protocol address, Point-to-Point Protocol over Ethernet (PPPoE), Internet Protocol version 6 (IPv6), priority field, Transmission Control Protocol (TCP) source port, and User Datagram Protocol (UDP) destination port.

[0056] The identifiers include the generic encapsulation method port identifier GEMPortID, the logical link identifier LLID, and the virtual local area network identifier VLANID.

[0057] Among them, the business slices are assigned to their respective business slices NSIY (Y = 0, 1, 2, 3, 4, 5, 6, 7, 8) according to their logical identifiers (e.g., LOID registration code, Password password).

[0058] To further explain, there is a slice mapping relationship between resource slices and service slices, as shown below: The OLT is virtually divided into up to 8 slices as resource slices D-NetX (X = 0, 1, 2, 3, 4, 5, 6, 7, 8); under each resource slice, the ONU is assigned to up to 8 service slices NSIY (Y = 0, 1, 2, 3, 4, 5, 6, 7, 8) based on its identifier. Example 1: Resource slice 1 (D-Net1) is divided into 3 service slices (NSI1, NSI2, NSI3); Example 2: Resource slice 2 (D-Net2) is divided into 2 service slices (NSI1, NSI2).

[0059] In one embodiment of this application, it is necessary to determine the first service slice corresponding to the terminal, customize the priority of service slice information, match one by one starting from the highest priority information, and identify NSIY (Y = 0, 1, 2, 3, 4, 5, 6, 7, 8). In exceptional cases, if no service slice information can be matched, it is automatically assigned to the default slice NSI0.

[0060] S203: Determine the slice information corresponding to the terminal based on the first resource slice and the first service slice.

[0061] It should be noted that after determining the first resource slice and the first service slice, the first resource slice and the first service slice are used as the slice information corresponding to the terminal.

[0062] In one embodiment of this application, as shown in FIG3, the ONU can report the physical identifier corresponding to its own resource information to the access network control system that performs the slice determination through the OLT. After receiving the resource information, the slice configuration information module feeds back the resource information to the slice configuration matching module, so that the slice configuration matching module determines the first resource slice according to the resource information and feeds back the first resource slice to the ONU through the OLT.

[0063] In one embodiment of this application, as shown in FIG4, the terminal can report its own service information to the access network control system that performs the slice determination through the OLT. After receiving the service information, the slice configuration information module feeds back the service information to the slice configuration matching module, so that the slice configuration matching module determines the first service slice corresponding to the terminal according to the service information corresponding to the terminal, and feeds back the first service slice to the ONU through the OLT.

[0064] The aforementioned slice determination method obtains the first resource slice of the first downlink port and the first service slice corresponding to the terminal; then, based on the first resource slice and the first service slice, it determines the slice information corresponding to the terminal. As can be seen from the above, this application determines the first resource slice and the first service slice by considering the actual resource situation of the optical network unit and the actual service situation corresponding to the terminal. Furthermore, in the process of determining the slice information corresponding to the terminal based on the first resource slice and the first service slice, it automatically allocates the resource slice and service slice corresponding to the terminal, optimizing the process of determining the first resource slice and the first service slice corresponding to the terminal, ensuring the portability of determining the slice information corresponding to the terminal, improving the business experience of industry customers, enhancing the flexibility and intelligence of the industrial PON network, reducing daily manual operation configuration of the industrial PON network, and meeting the needs of industry users for convenient operation of the industrial PON network.

[0065] In one embodiment, as shown in FIG5, when the terminal switches from accessing the first downlink port to accessing the second downlink port among the downlink ports of the first optical network unit, the above method may further include the following steps S501 to S502.

[0066] S501: If the terminal switches from accessing the first downlink port to accessing the second downlink port among the downlink ports of the first optical network unit, then the second resource slice corresponding to the second downlink port is obtained.

[0067] It should be noted that if the terminal switches from accessing the first downlink port to accessing the second downlink port among the downlink ports of the first optical network unit, the second resource slice of the second downlink port can be determined from the candidate resource slices corresponding to each downlink port based on the pre-determined candidate resource slices corresponding to each downlink port of the first optical network unit.

[0068] Specifically, a storage unit can be pre-set to record the candidate resource slices corresponding to each downlink port of the first optical network unit. When it is necessary to determine the second resource slice of the second downlink port, the storage unit can be searched according to the label of the second downlink port. If the downlink port label corresponding to a candidate resource slice is the same as the label of the second downlink port, then the candidate resource slice is used as the second resource slice of the second downlink port.

[0069] The second resource slice may be the same as or different from the first resource slice; no restrictions are imposed on the second resource slice here.

[0070] S502: Update the terminal's slice information according to the second resource slice.

[0071] It should be noted that before updating the terminal's slice information based on the second resource slice, it is possible to verify whether the second resource slice is the same as the first resource slice. If they are different, the first resource slice in the terminal's slice information is replaced with the second resource slice. If they are the same, there is no need to update the terminal's slice information. Alternatively, if the terminal's slice information carries the downlink label of the first downlink port, the downlink label of the first downlink port is replaced with the downlink label of the second downlink port.

[0072] In one embodiment of this application, as shown in FIG6, if the terminal switches from accessing the first downlink port to accessing the second downlink port among the downlink ports of the first optical network unit, the second resource slice corresponding to the second downlink port is obtained; it is verified whether the second resource slice is the same as the first resource slice. If they are not the same, the first resource slice in the terminal's slice information is replaced with the second resource slice. At this time, the slice information corresponding to the terminal is the second resource slice and the first service switch.

[0073] The above-described slice determination method, when the terminal switches from accessing the first downlink port to accessing the second downlink port among the downlink ports of the first optical network unit, determines the second resource slice corresponding to the second downlink port to update the terminal's slice information based on the second resource slice.

[0074] In one embodiment, as shown in FIG7, when the terminal switches from accessing the first optical network unit to accessing the third downlink port of the second optical network unit, the above method may further include the following steps S701 to S702.

[0075] S701: If the terminal switches from accessing the first optical network unit to accessing the third downlink port of the second optical network unit, it obtains the third resource slice corresponding to the third downlink port.

[0076] It should be noted that if the terminal switches from accessing the first optical network unit to accessing the third downlink port of the second optical network unit, the third resource slice of the third downlink port can be determined from the candidate resource slices corresponding to each downlink port of the second optical network unit based on the pre-determined candidate resource slices corresponding to each downlink port.

[0077] Specifically, a storage unit can be pre-set to record the candidate resource slices corresponding to each downlink port of the second optical network unit. When it is necessary to determine the second resource slice of the third downlink port, the storage unit can be searched according to the label of the third downlink port. If the downlink port label corresponding to a candidate resource slice is the same as the label of the third downlink port, then the candidate resource slice is used as the third resource slice of the third downlink port.

[0078] The third resource slice may be the same as or different from the first resource slice; no restrictions are imposed on the third resource slice here.

[0079] S702: Update the terminal's slice information based on the third resource slice.

[0080] It should be noted that before updating the terminal's slice information based on the third resource slice, it is possible to verify whether the third resource slice is the same as the first resource slice. If they are different, the first resource slice in the terminal's slice information is replaced with the third resource slice. If they are the same, there is no need to update the terminal's slice information. Alternatively, if the terminal's slice information carries the downlink label of the first downlink port, the downlink label of the first downlink port is replaced with the downlink label of the third downlink port.

[0081] In one embodiment of this application, as shown in FIG8, if the terminal switches from accessing the first optical network unit to accessing the third downlink port of the second optical network unit, it obtains the third resource slice corresponding to the third downlink port and verifies whether the third resource slice is the same as the first resource slice. If they are not the same, the first resource slice in the terminal's slice information is replaced with the third resource slice. At this time, the slice information corresponding to the terminal is the third resource slice and the first service switch.

[0082] The above-described slice determination method, when the terminal switches from accessing the first optical network unit to accessing the third downlink port of the second optical network unit, determines the third resource slice corresponding to the third downlink port, so as to update the slice information of the terminal based on the third resource slice.

[0083] In one embodiment, as shown in FIG9, when the service information corresponding to the terminal changes, the above method may further include the following steps S901 to S903.

[0084] S901: Verify whether the service information corresponding to the terminal has changed.

[0085] It should be noted that when it is necessary to verify whether the service information corresponding to the terminal has changed, a service information retrieval request can be sent to the terminal periodically. After receiving the service information retrieval request, the terminal will feed back the latest service information to the access network control system that executes the slice determination method. After receiving the latest service information, the access network control system will compare the latest service information with the historical service information. If they are different, it is determined that the service information corresponding to the terminal has changed; if they are the same, it is determined that the service information corresponding to the terminal has not changed.

[0086] The period for sending service information acquisition requests to terminals can be set or adjusted according to actual conditions and historical operating experience of the access network. Here, the period for sending service information acquisition requests to terminals is not limited.

[0087] To further explain, if it is pre-defined that after a terminal connects to the ONU, if any changes occur to the service information, it needs to actively send a service information change notification to the access network control system executing the slice determination method. Therefore, if the access network control system executing the slice determination method receives the service information change notification, it determines that the service information corresponding to the terminal has changed; if the access network control system executing the slice determination method does not receive the service information change notification, it determines that the service information corresponding to the terminal has not changed.

[0088] S902: If the service information corresponding to the terminal has changed, then the second service slice corresponding to the terminal shall be determined according to the changed service information corresponding to the terminal.

[0089] It should be noted that when it is necessary to determine the second service slice corresponding to the terminal based on the service information corresponding to the changed terminal, the priority of each candidate service slice can be preset. Based on the priority, each candidate service slice can be matched with the service information corresponding to the changed terminal one by one. The candidate service slice that matches the service information corresponding to the changed terminal is the second service slice corresponding to the terminal.

[0090] S903: Update the terminal's slice information according to the second service slice.

[0091] It should be noted that before updating the terminal's slice information based on the second service slice, it can be verified whether the second service slice is the same as the first service slice. If they are different, the first service slice in the terminal's slice information is replaced with the second service slice. If the terminal's slice information before the update is the first resource slice and the first service slice, then the terminal's slice information after the update is the first resource slice and the second service slice.

[0092] The above-described slice determination method determines the second service slice corresponding to the terminal based on the changed service information when the service information corresponding to the terminal changes. Then, the slice information of the terminal is updated based on the second service slice. This ensures the portability of determining the slice information corresponding to the terminal, improves the business experience of industry customers, enhances the flexibility and intelligence of industrial PON networks, and reduces the daily manual operation configuration of industrial PON networks.

[0093] In one embodiment, as shown in FIG10, when it is necessary to determine the resource slices corresponding to each downlink port of the first optical network unit, the above method may specifically include the following steps S1001 to S1003.

[0094] S1001: When the first optical network unit is connected to the access network control system, determine the initial resource slices corresponding to each downlink port of the first optical network unit.

[0095] It should be noted that, in order to ensure that the resource information corresponding to each downlink port of the first optical network unit can be successfully obtained in the future, the initial resource slices corresponding to each downlink port of the first optical network unit can be predetermined when the first optical network unit accesses the access network control system, so as to determine the initial resource slices corresponding to each downlink port of the first optical network unit when the first optical network unit accesses the access network control system.

[0096] As shown in Figure 11, after the ONU goes online and accesses the access network control system, the initial resource slices corresponding to each downlink port of the first optical network unit are determined based on the pre-set access rules.

[0097] S1002: Obtain the resource information corresponding to each downlink port of the first optical network unit based on the initial resource slices corresponding to each downlink port of the first optical network unit.

[0098] The resource information includes at least one of the following: the optical network unit supporting the maximum configuration or performance, the optical network unit in online or real-time operation, the maximum bandwidth supported by the passive optical network (PON), and the maximum bandwidth supported by the optical network unit.

[0099] S1003: Determine the resource slice corresponding to each downlink port of the first optical network unit based on the resource information corresponding to each downlink port of the first optical network unit.

[0100] It should be noted that when it is necessary to determine the resource slices corresponding to each downlink port of the first optical network unit, the priority of each candidate service slice can be preset. Based on this priority, each candidate service slice is matched with the resource information corresponding to each downlink port of the first optical network unit one by one. The candidate service slices that match the resource information corresponding to each downlink port of the first optical network unit are the resource slices corresponding to each downlink port.

[0101] The above-described slice determination method obtains the resource information corresponding to each downlink port of the first optical network unit based on the initial resource slices corresponding to each downlink port of the first optical network unit. Then, based on the resource information corresponding to each downlink port of the first optical network unit, it determines the resource slices corresponding to each downlink port of the first optical network unit.
