Description

Ethernet switch with bypass optical port

Technical Field

The utility model relates to the technical field of ring network switches, in particular to an Ethernet switch port bypass control system.

Background

In a cascade network or a loop self-healing network, a ring network switch is generally adopted, the ring network switch is positioned in a main network serial link, and a ring network interface can adopt an Ethernet electric port (short-distance transmission) or an Ethernet optical port (long-distance transmission). 1 ring network port connects to the upper node in the link and another ring network port connects to the lower node in the link, all network traffic on the link will pass through the switch. When one of the ring network switches fails (equipment fails, a system hangs up or software fails), traffic cannot pass through the network link, thereby threatening the normal operation and stability of the network. Although the reliability and redundancy of the transmission link can be improved by using the looped network self-healing protocol, when two or more node devices are powered down, the system hangs up or software fails, the information of all nodes (including the nodes which normally operate) between two failure points still cannot be transmitted, and a large amount of information can be lost.

Highly reliable systems, such as intelligent traffic systems, require real-time, reliable network communications to support functions such as vehicle monitoring, signal control, monitoring equipment, etc., and cannot allow for large-area information loss.
