Problems solved by technology

[0004] Existing CNCs can only create TSN flow forwarding rules and generate flow forwarding paths by themselves, and cannot use an external scheduler to generate scheduling policies, which is inconvenient to enhance the scheduling capability of TSN switching nodes

Abstract

The invention provides a scheduling method of a TSN network, a centralized network configurator and an external scheduler, the method is used for the centralized network configurator, and the method comprises the following steps: the centralized network configurator is respectively connected with an information acquisition interface and a configuration issuing interface to the external scheduler; the centralized network configurator sends a flow demand and a topological structure of the TSN to the external scheduler through the information acquisition interface; and the centralized network configurator receives scheduling configuration data packaged by the external scheduler through the configuration issuing interface, and the scheduling configuration data is generated by the external scheduler according to the flow demand and the topological structure and is used for configuring a scheduling strategy of the TSN switching node. The invention also correspondingly provides a scheduling method for the external scheduler and the external scheduler. According to the technical scheme of the invention, the scheduling capability of the TSN switching node is enhanced, and the switching capability of the TSN network is improved.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a scheduling method of a TSN network, a centralized network configurator and an external scheduler. Background technique [0002] IEEE 802.1cc defines a fully centralized TSN system architecture for TSN, including TSN EndStation (TSN EndStation), TSN Bridge (TSN Bridge), Centralized User Configuration (CUC) and Centralized Network Configurator (Centralized Network). Configuration, CNC), referred to as CUC and CNC. Among them, the CUC and the CNC belong to the network elements of the control plane. [0003] The TSN terminal is the sender or receiver of the stream; the CUC is used to receive the registration of the TSN terminal, and obtain the bandwidth capability of the TSN terminal from the registration information; the CUC is also used to receive the initial stream creation request of the TSN sending terminal (Talker), and match After the TSN sends the bandwidth of th...
