[0052] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0053] It should be noted that the terms "including" and "having" and their variations involved in the documents of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0054] At present, with the development of network communication technology, the existing network can carry a variety of services, such as voice, video, online games, web browsing, etc. In recent years, the demand for network bandwidth has grown exponentially. Although operators have improved the network's ability to carry and transmit data by continuously expanding physical bandwidth and related technologies, the increase in physical bandwidth always lags behind users' requirements for data transmission. Under the impact of large amounts of data, in order to ensure the reliability of the network's transmission of multiple services and the QoS (quality of service) of the corresponding services, most major telecom operators have chosen PON (Passive Optical Network) as broadband fiber access.

[0055] PON is a new type of fiber optic access network technology with low cost and high capacity. It adopts a point-to-multipoint structure. The PON system may include an optical line terminal (OLT), an optical distribution network (ODN) and at least one optical network unit (ONU). The OLT is connected to the ODN, and the ODN is connected to at least one ONU. The ONU includes a service interface, which can be connected to the user equipment through the service interface.

[0056] However, for the PON downlink between the OLT and the ONU, the existing message processing method is serial, that is, the messages are received and encapsulated sequentially, and there is a lack of a corresponding resource reservation mechanism.

[0057] Based on this, an embodiment of the present application provides a message processing method, which determines the target time slot corresponding to the message to be processed in multiple time slots of the XGEM partition in the TC frame in the downstream direction of the passive optical fiber network PON through the message type of the message to be processed, and encapsulates the message to be processed into the target time slot. Encapsulating the message to be processed into the corresponding target time slot and reserving other time slots except the target time slot can break through the limitation of sequential transmission, reserve time slot resources for data streams with special delay requirements, and is conducive to providing delay guarantee for data streams with special delay requirements.

[0058] The following is a brief introduction to the method of processing messages in the downlink between the OLT optical line terminal and the ONU optical network unit of the existing PON system. Figure 1 As shown in the figure, the transmission convergence layer of the OLT optical line terminal in the PON system processes messages in a serial manner, that is, it receives messages (SDU) in sequence, takes the messages as the payload of the XGEM frame in sequence, adds the frame header H, encapsulates them into XGEM frames, and then sends the XGEM frames to the framing sub-layer (FS). The XGEM frames are used as the payload of the FS frames, and assemble the TC frames in sequence. Since each TC frame has a period of 125us, if a message spans two adjacent TC frames during the process of assembling the TC frame, the message is divided into two message fragments (SDU fragment1 and SDU fragment2) according to the actual remaining available length of the previous TC frame, encapsulated into two XGEM frames, and assembled into two adjacent TC frames (i.e., the end of the previous TC frame and the beginning of the next TC frame).

[0059] Figure 2The schematic diagram of the traditional PON protocol stack provided by the embodiment of the present application, in the traditional PON protocol stack, the user data interface (User Data Client) sends the data message to the user data adapter (User Data Adapter), outputs the data message, and the optical network unit management and control interface (OMCI Client) sends the operation and maintenance message to the optical network unit management and control adapter (OMCI Adapter), outputs the operation and maintenance message. Both the data message and the operation and maintenance message are sent to the XGEM encapsulation engine (XGEM Engine) for XGEM frame encapsulation, and the encapsulated XGEM frame is sent to the XGEM partition (partition) of the framing sublayer (FS frame / burst) for TC frame framing processing. In the framing sublayer, the control information partition (PLOAM partition) of the physical layer operation management and maintenance can be added before the XGEM partition, and the header field (Embedded header fields) can be embedded. Finally, the TC frame is transmitted through the physical layer (PHY burst timing and profile control). In the above process, XGEM frame encapsulation, TC frame framing and TC frame transmission are all performed sequentially, lacking a corresponding resource reservation mechanism.

[0060] Based on this, the embodiment of the present application adds a Slicing Schedule module to the traditional PON protocol stack, such as Figure 3 As shown. The Slicing Schedule module can receive the data message output by the user data adapter (User Data Adapter) and the operation and maintenance message output by the optical network unit management and control adapter (OMCI Adapter), and put the message into the corresponding target time slot according to the message type and the slice identifier associated with the message in the time slot pre-divided by the XGEM partition (partition) time. In the target time slot, the message is sent to the XGEM encapsulation engine (XGEM Engine) for XGEM frame encapsulation, and the encapsulated XGEM frame is sent to the XGEM partition (partition) of the framing sublayer (FS frame / burst) for TC frame framing processing, thereby realizing the reservation of time slot resources.

[0061] like Figure 4 As shown, the message processing method applied by the slice scheduling module provided in the embodiment of the present application may include the following steps:

[0062] Step S401, receiving a message to be processed.

[0063] The to-be-processed messages received by the slice scheduling module may include multiple message types.

[0064] In an optional implementation, the message to be processed may include three message types, the first message type is an identified type, the message corresponding to the identified type is an identified data message, and the identified data message has an associated slice identifier. The second message type is an unidentified type, the message corresponding to the unidentified type is an unidentified data message without an associated slice identifier, and the third message type is an operation and maintenance type, and the message corresponding to the operation and maintenance type is an operation and maintenance message without an associated slice identifier. The slice scheduling module can determine the target time slot corresponding to the message to be processed according to the message type of the message to be processed.

[0065] Among them, the slice identifier associated with the message to be processed can be a slice identifier carried by the message to be processed, or the slice identifier associated with the message to be processed can be a slice identifier mapped by the message to be processed.

[0066] Step S402: According to the message type of the message to be processed, a target time slot corresponding to the message to be processed is determined from multiple time slots of the XGEM partition in the TC frame.

[0067] Among them, the time of the XGEM partition of a TC frame includes multiple time slots, each time slot has at least one corresponding slice identifier, the number of time slots, the available length of each time slot, whether each time slot supports the transmission of operation and maintenance messages, and whether each time slot supports the transmission of unidentified data messages, which can all be adaptively configured according to actual needs.

[0068] Exemplarily, the time slot configuration of the XGEM partition time can be shown in Table 1 below, and the XGEM partition can be divided into 5 time slots, namely time slot 1, time slot 2, time slot 3, time slot 4 and time slot 5. Among them, the length of time slot 1 is L1, the length of time slot 2 is L2, the length of time slot 3 is L3, the length of time slot 4 is L4, and the length of time slot 5 is L5. Further, time slot 1 can be set to support the transmission of data packets with associated slice identification 1, and does not support the transmission of operation and maintenance messages and unidentified data packets. Time slot 2 can be set to support the transmission of data packets with associated slice identification 2, and does not support the transmission of operation and maintenance messages and unidentified data packets. Time slot 3 can be set to support the transmission of data packets with associated slice identification 1, operation and maintenance messages, and unidentified data packets. Time slot 4 can be set to support the transmission of data packets with associated slice identification 3, and does not support the transmission of operation and maintenance messages and unidentified data packets. Time slot 5 can be set to support the transmission of data packets with associated slice identification 4, operation and maintenance messages, and unidentified data packets. The slice scheduling module can determine the target time slot corresponding to the message to be processed according to the message type supported for transmission in each time slot from time slot 1 to time slot 5.

[0069] It should be noted that the time slot configuration of the XGEM partition time includes but is not limited to the time slot configuration method shown in Table 1. The time slot configuration method in Table 1 is only used for example and is not intended to limit the time slot configuration of the XGEM partition time of this application.

[0070]

[0071]

[0072] Table 1

[0073] In an optional implementation, the message to be processed received by the slice scheduling module may be an identified data message having an associated slice identifier, which corresponds to the slice identifier of the time slot. In order to distinguish the slice identifier associated with the message to be processed from the slice identifier in the time slot, the identifier associated with the message to be processed is referred to as the target slice identifier hereinafter.

[0074] Exemplarily, the slice scheduling module can first use the current time slot corresponding to the current moment as the time slot to be matched among multiple time slots, and repeat the following steps: if the slice identifier corresponding to the time slot to be matched does not match the target slice identifier associated with the message to be processed, or the time slot to be matched does not have an available time length, then the next time slot of the time slot to be matched can be used as a new time slot to be matched, until the slice identifier corresponding to the time slot to be matched matches the target slice identifier associated with the message to be processed, and the time slot to be matched has an available time length, and the time slot to be matched is used as the target time slot.

[0075] Specifically, taking the time slot configuration method of Table 1 as an example for explanation, assuming that the target slice identifier associated with the to-be-processed message is identifier 1, and the time slot corresponding to the current moment is time slot 1, it can be determined that the slice identifier 1 corresponding to time slot 1 matches the target slice identifier, that is, time slot 1 supports the transmission of the to-be-processed message associated with slice identifier 1. After determining that the current time slot 1 supports the transmission of the to-be-processed message associated with slice identifier 1, it can be determined whether time slot 1 has an available duration. If time slot 1 has an available duration, time slot 1 can be determined as the target time slot.

[0076] Furthermore, if Figure 5 As shown, the message with association identifier 1 (slice 1 SDU) can be placed in time slot 1 of the current XGEM partition (XGEMpartition) time, and the target time slot corresponding to the message with association identifier 2 (slice 2 SDU) is time slot 2. Since time slot 1 does not support the transmission of the message with association identifier 2, while time slot 2 supports the transmission of the message with association identifier 2, and time slot 2 has not yet started, the message with association identifier 2 can be placed in the cache corresponding to time slot 2, so that the time slot resources of time slot 1 are not occupied, thereby reserving time slot resources for the message with association identifier 1.

[0077] A buffer of a time slot may include multiple messages. In an optional embodiment, a FIFO (first input first output) method may be used to process the multiple messages.

[0078] In some embodiments, if a message with association identifier 1 is received during the ongoing time interval of time slot 1, the message with association identifier 1 can be placed in time slot 1 of the current XGEM partition time. Therefore, even if the time of receiving the message with association identifier 1 is later than the time of receiving messages with other associated identifiers, or later than the time of receiving unidentified data messages and operation and maintenance messages, the message with association identifier 1 can be transmitted earlier than the encapsulation of other messages, thereby improving the traditional message processing mechanism of sequentially receiving messages and sequentially encapsulating them, and providing priority guarantee for transmitted messages on the PON downlink.

[0079] In other embodiments, if no message with associated identifier 1 is received during the ongoing time interval of time slot 1, the time slot resource of time slot 1 is still reserved and is not used for messages with other associated identifiers, data messages without identifiers, and operation and maintenance messages. If in other time slots of the current XGEM partition time, for example, if a message with associated identifier 1 is received in time slot 2 of the current XGEM partition time, that is, the time slot corresponding to the current moment is time slot 2. It can be determined that the slice identifier corresponding to time slot 2 is identifier 2, so time slot 2 does not match the target slice identifier associated with the message to be processed, and it is further determined whether the next time slot of time slot 2 matches the target slice identifier associated with the message to be processed. The next time slot of time slot 2 is time slot 3, and the slice identifier corresponding to time slot 3 is identifier 1. Therefore, time slot 3 matches the target slice identifier associated with the message to be processed, and it can be determined whether time slot 3 has an available duration. If time slot 3 has an available duration, time slot 3 can be determined as the target time slot, and the message with associated identifier 1 can be put into time slot 3 for caching.

[0080] For another example, if the current time slot is time slot 4, at this time, it can be determined whether time slot 4 matches the target slice identifier associated with the message to be processed. The slice identifier corresponding to time slot 4 is identifier 3. Therefore, time slot 4 does not match the target slice identifier associated with the message to be processed. Continue to determine whether the next time slot of time slot 4 matches the target slice identifier associated with the message to be processed. The next time slot of time slot 4 is time slot 5. The slice identifier corresponding to time slot 5 is identifier 4. Therefore, time slot 5 does not match the target slice identifier associated with the message to be processed. Continue to determine the next time slot of time slot 5, that is, time slot 1 of the next XGEM partition (XGEM partition). Since time slot 1 matches the target slice identifier associated with the message to be processed, and time slot 1 has an available duration. Therefore, the message with association identifier 1 can be put into time slot 1 of the next XGEM partition (XGEM partition) time for cache, and after time slot 1 of the next XGEM partition (XGEM partition) time starts, the message is processed accordingly.

[0081] In another optional implementation, the message to be processed received by the slice scheduling module may be an unidentified data message.

[0082] The target time slot corresponding to the unidentified data message can be determined in the following way:

[0083] Take the current time slot as the time slot to be matched, and repeat the following steps: if the time slot to be matched does not support the transmission of unidentified data messages, or the time slot to be matched does not have an available time length, then take the next time slot of the time slot to be matched as the new time slot to be matched, until the time slot to be matched supports the transmission of unidentified data messages and the time slot to be matched has an available time length, and then take the time slot to be matched as the target time slot.

[0084] Exemplarily, the time slot configuration method in Table 1 is continued as an example for explanation. Assuming that the message to be processed is an unidentified data message, the time slot corresponding to the current moment is time slot 1. It can be determined that time slot 1 does not support the transmission of unidentified data messages. The next time slot of time slot 1 is continued to be determined. The next time slot of time slot 1 is time slot 2. Time slot 2 also does not support the transmission of unidentified data messages. The next time slot of time slot 2 is continued to be determined. The next time slot of time slot 2 is time slot 3. Time slot 3 supports the transmission of unidentified data messages. Further, it can be determined whether time slot 3 has remaining available time. Time slot 3 has remaining available time. Therefore, time slot 3 can be determined as the target time slot.

[0085] In another optional implementation, the message to be processed received by the slice scheduling module may be an operation and maintenance message.

[0086] The target time slot corresponding to the operation and maintenance message can be determined in the following way:

[0087] Take the current time slot as the time slot to be matched, and repeat the following steps: if the time slot to be matched does not support the transmission of operation and maintenance messages, or the time slot to be matched does not have an available time length, then take the next time slot of the time slot to be matched as the new time slot to be matched, until the time slot to be matched supports the transmission of operation and maintenance messages and the time slot to be matched has an available time length, and then take the time slot to be matched as the target time slot.

[0088] Exemplarily, the time slot configuration method in Table 1 is continued as an example for explanation. Assuming that the message to be processed is an operation and maintenance message, the time slot corresponding to the current moment is time slot 1. It can be determined that time slot 1 does not support the transmission of operation and maintenance messages. Continue to determine the next time slot of time slot 1. The next time slot of time slot 1 is time slot 2. Time slot 2 also does not support the transmission of operation and maintenance messages. Continue to determine the next time slot of time slot 2. The next time slot of time slot 2 is time slot 3. Time slot 3 supports the transmission of operation and maintenance messages. Further, it can be determined whether time slot 3 has remaining available time. Time slot 3 has remaining available time. Therefore, time slot 3 can be determined as the target time slot.

[0089] It should be noted that any time slot can support the transmission of both unidentified data messages and operation and maintenance messages, or any time slot can only support the transmission of unidentified data messages and not support the transmission of operation and maintenance messages, or any time slot can not support the transmission of unidentified data messages and only support the transmission of operation and maintenance messages. The message type corresponding to which each time slot supports transmission can be freely set according to actual needs, and this application does not limit this.

[0090] Step S403: encapsulate the message to be processed into the target time slot.

[0091] After the slice scheduling module determines the target time slot corresponding to the message to be processed, the message to be processed can be encapsulated into the target time slot.

[0092] In an optional implementation manner, if the target time slot has started, the message to be processed may be encapsulated.

[0093] Exemplarily, assuming that the target time slot has already started, a first determination may be made to determine whether the remaining available duration of the target time slot is greater than or equal to the duration required for transmitting the message to be processed.

[0094] If the remaining available time length of the target time slot is greater than or equal to the time length required to transmit the message to be processed, the available length of the target time slot can be updated according to the encapsulation length of the message to be processed, and the message to be processed can be encapsulated.

[0095] Specifically, assuming that the target time slot is time slot 1, the remaining available time length of time slot 1 is L1, the time length required to transmit the message to be processed is L1', L1>L1', then the available length of time slot 1 can be updated to (L1-L1'), and further, the message to be processed can be used as the payload part, and the frame header of the XGEM frame can be added to obtain the XGEM frame. After obtaining the XGEM frame, the XGEM frame can be placed in the XGEM partition for TC frame framing.

[0096] If the remaining available time of the target time slot is less than the time required to transmit the message to be processed, a second judgment may be performed to determine whether the remaining available time of the target time slot is greater than the time required to transmit the frame header of an XGEM frame.

[0097] If the remaining available time of the target time slot is greater than the time required to transmit the frame header of an XGEM frame, the message to be processed can be fragmented, the first message fragment obtained by the fragmentation can be encapsulated into an XGEM frame, and the XGEM frame can be processed by TC frame framing. According to the encapsulation length of the first message fragment, the available length of the target time slot is updated, the next target time slot is determined for the second message fragment obtained by the fragmentation, the second message fragment is placed in the cache of the next target time slot, and after waiting for the start of the next target time slot, the second fragment is encapsulated in an XGEM frame and processed by TC frame framing.

[0098] If the remaining available time of the target time slot is less than or equal to the time required to transmit the frame header of an XGEM frame, the next target time slot can be determined for the message to be processed, and the message to be processed can be placed in the cache of the next target time slot. After waiting for the next target time slot to start, the message to be processed can be encapsulated.

[0099] Specifically, assuming that the target time slot is time slot 2, the remaining available time of time slot 2 is L2, the time required to transmit the message to be processed is L2', L2≤L2', then it can be determined whether L2 is greater than the time required to transmit the frame header of an XGEM frame.

[0100] If L2 is greater than the time required to transmit the frame header of an XGEM frame, the message to be processed can be fragmented, the first message fragment obtained by the fragmentation can be encapsulated into an XGEM frame, and the XGEM frame can be processed by TC frame framing. According to the encapsulation length of the first message fragment, the available length of time slot 2 is updated to (L2-encapsulation length of the first message fragment), and the next target time slot is determined for the second message fragment obtained by the fragmentation. The second message fragment is placed in the cache of the next target time slot, and after waiting for the start of the next target time slot, the second fragment is encapsulated in an XGEM frame and processed by TC frame framing.

[0101] If L2 is less than or equal to the time required to transmit the frame header of an XGEM frame, the next target time slot can be determined for the message to be processed, the message to be processed can be placed in the cache of the next target time slot, and the message to be processed can be encapsulated after the next target time slot starts.

[0102] In another optional implementation, if the target time slot has not started at the current moment, the message to be processed can be saved in the cache corresponding to the target time slot, and the message to be processed is encapsulated when the target time slot arrives. The process of encapsulating the message to be processed has been described in detail above and will not be repeated here.

[0103] Based on the same inventive concept, an embodiment of the present invention further provides a message processing method, such as Figure 6 As shown, the method may include:

[0104] Step S601, receiving a message to be processed.

[0105] Step S602: According to the message type of the message to be processed, a target time slot corresponding to the message to be processed is determined from multiple time slots of the XGEM partition in the TC frame.

[0106] Step S603, determining whether the target time slot starts.

[0107] If the target time slot starts, step S604 may be executed, and if the target time slot has not started, step S605 may be executed.

[0108] Step S604: determine whether the remaining available time length of the target time slot is greater than or equal to the time length required for transmitting the message to be processed.

[0109] If the remaining available time of the target time slot is greater than or equal to the time required to transmit the message to be processed, step S606 may be executed. If the remaining available time of the target time slot is less than the time required to transmit the message to be processed, step S607 may be executed.

[0110] Step S605: save the message to be processed into a cache corresponding to the target time slot.

[0111] Step S606, performing packaging processing.

[0112] Step S607, determine whether the remaining available time length of the target time slot is greater than the time length required to transmit a frame header of an XGEM frame. If yes, step S608 may be executed. If no, step S610 may be executed.

[0113] Step S608, fragment the message to be processed.

[0114] Step S609, determine whether the message fragment is fragment 1. If yes, execute step S606. If no, execute step S610.

[0115] Step S610, matching the next target time slot.

[0117] The receiving unit 701 is used to receive a message to be processed.
