Embodiment Construction
[0068] In this embodiment, a bandwidth reservation method for sporadic messages in the TSN network of intelligent networked vehicles, such as figure 1 As shown, this method constructs a real-time frequency coupling formula for message classification for various messages in the TSN network of intelligent networked vehicles, and establishes sporadic real-time message and non-sporadic real-time message models; As a condition, find the boundary area where the bandwidth of sporadic real-time messages can be reserved; take this boundary area as the search area, and aim at the minimum total transmission time of various messages in the switch, traverse to find the sporadic real-time messages and non-sporadic messages. The optimal reserved bandwidth value; specifically, it is carried out according to the following steps:
[0069] Step 1. Obtain vehicle TSN network information;
[0070] Collect the set M of all messages in the TSN network of intelligent connected vehicles, among which...
