Abstract

The invention relates to a joint optimization method for path selection and gating scheduling in a time-sensitive network, which belongs to the technical field of time-sensitive networks, and comprises the following steps: S1, discovering a TSN network topology by CNC, and abstracting the TSN network topology into a network directed graph; s2, the terminal equipment sends a TSN connection request to the CUC, and the CUC sends the connection request to the CNC; s3, the CNC selects K shortest paths as alternative paths; s4, the CNC selects m optimal paths; s5, the CNC finds an optimal transmission path for the TT flow and finds a proper transmission path for the non-TT flow; s6, CNC traversal is completed; s7, configuring a gating list for the optimal transmission path of the TT flow of each pair of terminal equipment; and S8, the CNC packages the calculation result into a gating scheduling table, configures the gating scheduling table to the TSN switch, and sends the flow transmission calculation result to the TSN terminal equipment through the CUC.

Description

technical field [0001] The invention belongs to the technical field of time-sensitive networks, and relates to a joint optimization method of path selection and gate control scheduling in time-sensitive networks. Background technique [0002] With the continuous development of industrial Internet technology, deterministic real-time communication has been introduced into the field of aerospace and industrial automation to ensure the performance of time-critical flows and the security of the system. Time-Sensitive Networking (TSN) is a set of standards developed by the Time-Sensitive Networking Task Group (TSN TG) of the IEEE 802.1 working group for real-time communication over Ethernet networks with bounded delay and jitter. TSN brings industrial-grade robustness to Ethernet to facilitate real-time, safety-critical applications (e.g., Industry 4.0 and cyber-physical systems) and supports time-critical and best-effort traffic over a common communications infrastructure. trans...
