Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the field of network communication, and specifically, relate to but are not limited to link path calculation methods, devices, terminals, and computer-readable storage media. Background technique [0002] 3GPP decided to use the SBA architecture (Service-based architecture) as the 5G unified infrastructure. The official name of the 5G system architecture standard project is: 5G System Architecture (5G System Architecture), referred to as 5GS. [0003] When 5GS needs to support TSN (Time Sensitive Network) requirements, 5GS plans to adopt the method of simulating a TSN bridge to reduce the impact on other TSN entities (such as CNC, CUC, End-Station, etc.), and at the same time, the inside of 5GS is a black hole to the outside. box, and won't drastically change the 5GS either. The function of 5GS acts as a bridge of the TSN network, consisting of ports on the UPF (User Plane Function...
