[0004] Figure 1 This is a schematic diagram of the slicing packet network SPN network architecture. As shown in the figure, 5G transmission is based on the slicing transmission network SPN (Slicing Packet Network) mechanism.

[0068] The inventors noticed during the invention process that:

[0069] Currently, there is no technical solution for ultra-low latency transmission slice channels in SPN networks.

[0070] Furthermore, the SPN transmission network device establishes multiple transmission slice channels, receives the service at the UNI interface, encapsulates the service with relevant transmission labels inside the SPN device, sends it to the corresponding NNI interface, and transmits it in the corresponding transmission slice pipeline.

[0071] In order to meet the isolation of transmission slices and ensure the needs of transmission bandwidth, the transmission slice channel is divided into multiple transmission slice channels in a time-division multiplexing manner. After service encapsulation, each service is transmitted in each defined transmission slice.

[0072] In the SPN transmission slice channel, the channels of each slice are isolated from each other to ensure the bandwidth within each slice, realize the physical isolation of the slices, ensure the bandwidth, and achieve the slicing effect of the transmission slice channel. However, in some applications (such as power grid slicing), it is proposed that the slice pipeline not only needs to meet the isolation requirements, but also requires that it can be transmitted with lower latency and higher priority.

[0073] Figure 3 The following is a schematic diagram of power grid services. As shown in the figure, in the power grid slice, in addition to the independent channel of the slice, it is hoped that the power grid service can be transmitted at a faster rate and lower latency. The power grid data of each DTU (Data Terminal Unit) is expected to be transmitted faster and with lower latency based on the isolated slice pipeline.

[0074] Based on this, the embodiment of the present invention will provide a solution for a new transmission slice channel on a transmission slice packet network. By establishing a new transmission slice channel on an SPN slice network device, reliable transmission of the transmission slice channel is realized on the SPN slice pipeline, and higher priority transmission channels and lower latency service transmission are realized, so as to realize more flexible, efficient and low latency transmission of the SPN transmission slice channel. It provides customers with higher priority, lower latency and higher reliability transmission slice services to meet the transmission slice requirements of more business types.

[0075] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0076] Figure 4 A schematic diagram of a flow chart for implementing a transmission channel allocation method, as shown in the figure, may include:

[0077] Step 401: Determine the end-to-end slice service to be transmitted;

[0078] Step 402: In the transmission slice pipeline of the SPN, an ultra-low latency transmission slice channel is allocated to each slice service, wherein each transmission channel includes m transmission slice channels, each transmission channel is divided into n time slots, each transmission slice channel corresponds to one or more transmission time slots, and m and n are natural numbers.

[0079] Specifically, in the transmission slice pipeline of SPN, a transmission slice channel is allocated to each service, and the transmission slice channel is defined according to the allocated time slot. The transmission channel is divided into n time slots, one or more time slots can be defined as a transmission slice channel, and the transmission channel is divided into m transmission slice channels according to the time slot.

[0080] Figure 5 This is a schematic diagram of the forwarding channel relationship of the slice packet network. As shown in the figure, when a slice service is transmitted, each slice service corresponds to a service transmission queue and is bound to a transmission slice channel. Each transmission slice channel corresponds to one or more transmission time slots, and each slice service corresponds to one or more transmission time slots.

[0081] In order to achieve high-priority pipeline transmission during slice service transmission, time slot preemption can be used to occupy idle time slots for transmission, thereby supporting low-latency forwarding transmission for high-priority services. The following describes the implementation of the high-priority low-latency transmission slice channel of the transport network SPN.

[0082] During implementation, it may also include:

[0083] Determine the priority of the end-to-end slice services to be transmitted;

[0084] According to the priority, each slice service is assigned a transmission slice channel corresponding to the priority.

[0085] Specifically, in the transmission network, a transmission slice pipeline can be established for end-to-end slice services through the transmission management and control system, and then high-priority transmission slice channels can be defined according to the needs of high-priority slice services to achieve lower latency slice transmission.

[0086] Establish transmission slice channels at the service transmission starting point and destination point, and allocate corresponding time slots;

[0087] For high-priority transmission slice channels, preemptible time slot resources are allocated, and idle time slot resource bandwidth is occupied for transmission; that is, in implementation, when time slots are allocated for transmission slice channels allocated to high-priority slice services, idle time slots are occupied for transmission when the time slots of the transmission slice channels corresponding to the priority are insufficient.

[0088] When a service enters a transmission slice channel, it can decide whether to perform high-priority, low-latency transmission based on the service priority identifier, that is, whether to perform high-priority transmission slice channel transmission; that is, in implementation, the priority of the end-to-end slice service to be transmitted is determined based on the service priority identifier.

[0089] In implementation, the transmission slice channel corresponding to the slice service with a high priority identifier is a high priority low latency slice transmission channel;

[0090] The transmission slice channel corresponding to the slice service without a high priority identification is the slice transmission channel of the ordinary transmission slice time slot.

[0091] Specifically, services without high priority identification occupy ordinary transmission slice time slots for transmission; services with high priority identification enable high priority low latency slice transmission.

[0092] The following is an example to illustrate.

[0093] Figure 6 This is a schematic diagram of the forwarding channel relationship. Figure 7 This is a schematic diagram of the relationship between the forwarding channel and the time slot. As shown in the figure, when transmitting slice services, it can be as follows:

[0094] Slice and encapsulate high-priority business data;

[0095] When sending, high-priority service data slices are placed in the normal transmission slice time slot and the preemption time slot for transmission;

[0096] When using the occupied time slot, the mark of the occupied time slot is changed to high priority service occupation; that is, in implementation, the occupied time slot can be marked as high priority service occupation.

[0097] When receiving, the corresponding service is determined according to the timeslot mark, and the high-priority service is received according to the timeslot occupied by the transmission, and the high-priority service is restored;

[0098] Services with high priority levels occupy more time slot resources, achieving high priority and lower latency transmission.

[0099] After completing the transmission of the high-priority slice service, the occupied time slot resources can be released and marked as an idle time slot, so that other high-priority slice services can occupy the transmission, thereby realizing the sharing of idle time slot transmission resources; that is, during implementation, it can also include: after completing the transmission of the high-priority slice service, the occupied time slot resources are released and marked as an idle time slot.

[0100] The transmission slice message format can be shown in the following table:

[0101]

[0102] In the transmission slice network, before entering the transmission slice pipeline, time slots are allocated according to the priority of the business data message. Normal priority messages occupy fixed allocated time slots, and high priority messages occupy fixed time slots and preempted time slots for transmission, establishing a higher priority and lower latency transmission channel.

[0103] The seized time slot is released when not in use, supporting the sharing of slice time slot resources and improving resource utilization.

[0104] Based on the same inventive concept, a transmission control system and a computer-readable storage medium are also provided in an embodiment of the present invention. Since the principles of solving the problems by these devices are similar to those of the transmission channel allocation method, the implementation of these devices can refer to the implementation of the method, and the repeated parts will not be repeated.
