TSN-Based Backbone Network of Train Control Management System

Table 3

Example: access method for subsystems.

Subsystems	Method
Critical subsystems (MVCU, RIOM, etc.) (high priority)	The subsystem itself supports the TSN network and is directly connected to the backbone network through the TSN switch.
Critical subsystems (MDCU, ACU, etc.) (medium priority)	The subsystem itself does not support the TSN network and needs to be converted to a TSN network through a TSN switch and then connected to the backbone network.
Noncritical subsystems (PIS, CCTV, etc.) (low priority)	The subsystem itself does not support the TSN network and does not need to be converted to a TSN network through a TSN switch, connected to the backbone network directly.
