Embodiment 1

[0124] Embodiment 1 of the present invention provides a management method for implementing multiplexing technology based on packet slicing, which divides overhead into path-associated overhead and bypass overhead. The path-associated overhead is embedded in a cell header and forwarded with services. , which is used to monitor service forwarding behavior; the monitoring service forwarding behavior specifically includes one or more of cell reverse sequence detection, cell loss detection, cell error code detection, link quality monitoring, and path associated detection.

[0125] The bypass overhead is used for the management of the channel container itself and / or the content of the container; wherein, the associated overhead is used to mark the channel container object and overhead information with high real-time requirements, and the bypass overhead is also used to carry other Real-time requirements are not high overhead.

[0126] The path associated overhead and the bypass over...

Embodiment 2

[0184] Figure 5 A schematic diagram of the implementation of a technical system in an embodiment of the present invention. As shown in the figure, the business process is, the business is "sending" to complete the multiplexing and encapsulation of the sub-channel to the channel and then to the interface; the "relay" node completes the channel termination, and the sub-channel business is crossed from east to west and then re-encapsulated and sent to the interface. Downstream node; the "receiving" node completes the termination of the channel and the sub-channel, extracts the business from the sub-channel and transfers it to the downstream device. In this technical realization, the equipment mainly includes the following modules and systems:

[0185] 1) Multiplexing management system: Overall management and configuration of the path-associated overhead processing module, bypass overhead processing module and their configuration relationships with other modules of the service f...

Embodiment 3

[0211] An embodiment of the present invention provides a management system for implementing multiplexing technology based on packet slices, which belongs to the specific presentation of the system framework presented in Embodiment 2 based on the method described in Embodiment 1. The system includes a sending node In the scenario of one or more relay nodes, and receiving nodes, when the time slot configuration table is switched from CA to time slot configuration table CB, the system specifically includes:

[0212] At T0, the service is normal and the configuration is normal. The bypass module, the associated module, and the forwarding module use the time slot configuration table CA, and the corresponding synchronization pattern is recorded as SA.

[0213] At time T1, each node passes through the bypass module and starts the handover negotiation from the time slot configuration table CA to the time slot configuration table CB through the bypass overhead, and the corresponding syn...

Abstract

The invention relates to the technical field of communication information transmission, and provides a management method and a system for realizing multiplexing technology based on packet slices. The method includes dividing the overhead into an associated overhead and a bypass overhead. The attached overhead is embedded in a cell header and forwarded with a service, and is used for monitoring service forwarding behavior; the bypass overhead is used for channel container self-management and operation. / or container content management; the path-dependent overhead and the bypass overhead are based on a synchronization mechanism, so that the bypass overhead can be managed in real time for the multiplexed channel containers and / or sub-channel containers. By adding a bypass overhead and providing a corresponding synchronization mechanism, the present invention can achieve effective management and maintenance of multiplexing while improving the payload carrying efficiency of the hard pipe and reducing the complexity of the equipment.

Description

【Technical field】 [0001] The present invention relates to the technical field of communication information transmission, in particular to a management method and system for realizing multiplexing technology based on packet slices. 【Background technique】 [0002] In bearer network deployment, "end-to-end slicing" has always been a hot topic. "Small grain" is an important concept in "end-to-end slicing". A small particle is a "hard pipe" that can realize an end-to-end similar time-division multiplexing (Time-Division Multiplexing, TDM for short) hard isolation effect based on the Ethernet technology. Its rate is generally less than 1Gbps, and can reach 10Mbps or even lower. There are various techniques to implement the hard pipe solution, among which "multiplexing based on packet slices" is a common technique. In this technology, the original services are uniformly imported into the "sub-channel container", the "sub-channel container" is uniformly divided into equal-length ...
