Problems solved by technology

According to IEEE802.1Qbv, the queue scheduling is implemented strictly according to the switch state of the transmission gate queue. In this case, the time-sensitive frame is also cached first, and is allowed to pass through after waiting for the transmission gate queue corresponding to the scheduling to be opened. When scheduling forwarding, the delay of time-sensitive frames will be increased

Abstract

The invention relates to an information transmission method and device, a computer storage medium and a terminal, which are applied to a time sensitive network and the method comprise the following steps: respectively marking different types of messages according to the types of the received messages; Caching the marked message; According to the type of the cached message and the real-time state of the egress port door queue corresponding to the message, carrying out transmission processing on the cached message; Wherein the type of the message comprises a time sensitive frame and a non-time sensitive frame. According to the embodiment of the invention, the message is transmitted according to the real-time state of the egress port gate queue, so that the transmission delay of the time sensitive frame is reduced.

Description

technical field [0001] This article involves but is not limited to communication technology, especially a method, device, computer storage medium and terminal for information transmission. Background technique [0002] With the rapid development of industrial automation, Time Sensitive Network (TSN, TimeSensitive Network) developed by IEEE 802.1 will become one of the future development trends. TSN can guarantee the packet delay of the switching network, and time-sensitive frames and non-time-sensitive frames can be transmitted in a network without worrying about data collision. [0003] TSN mainly solves the three problems of clock synchronization, data scheduling and system configuration. Among them, in the data scheduling process, after the node receives the data frame, it will copy the data frame into two copies, filter and cache respectively, and wait for queue scheduling and forwarding. According to IEEE802.1Qbv, the queue scheduling is implemented strictly according ...
