Problems solved by technology

[0004] However, if any one switch or a stack line in the switch stack 100 fails, it will lead to the collapse of the entire stack, because the switch stack 100 is configured as figure 1 A single concatenated stack is shown without a redundant link, so the remaining switches cannot be stacked together to form a new switch stack until the network administrator manually troubleshoots the problem

Embodiment Construction

[0018] Such as Figure 2A As shown, four switches 210a-d are stacked together to form a switch stack 200, and each switch 210a, 210b, 210c, and 210d is equipped with stacking modules 212a, 212b, 212c, and 212d respectively, and each stacking module includes An online connection port (uplink port) and an online connection port (downlink port). For example, on the switch 210b of the switch stack 200, the upper connection port 214b is connected to the first switch next to it, that is, the upper switch 210a, and the lower connection port 216b is connected to the second switch next to it. , that is, the lower switch 210c. According to the present invention, every two switches in the switch stack are connected to form a closed loop, in other words, the stack connection 220a is connected between the lower connection port 216a of the stack module 212a and the upper connection port 214b of the stack module 212b Between, the stacking connection 220b is connected between the lower conn...

Abstract

A redundant connection management switch suitable for the closed-loop switch stack is composed of a stack module, a processor and a management module. The said stack module has an upward connecting port for connecting the adjacent upper switch in stack and a downward connecting port for connecting the adjacent lower switch in stack. When a cut-off command is received, the action of control bus for downward connection is lost. When a reconnection cammand is received, its action can be restored.

Description

technical field [0001] The present invention relates to computer networks, in particular to a redundant link management switch suitable for switch stacks. Background technique [0002] A typical computer network consists of many nodes (computers), connection media (wired or wireless), and network devices such as routers and hubs. In the case of the internet (intemet), these elements work together to allow one computer to transmit information to other computers, possibly on the other side of the world. A switch is a fundamental part of most networks, allowing several users to simultaneously transmit information on a network without slowing down others, just as a router enables different networks to communicate with each other, a switch It allows different nodes in the network to directly communicate with each other in a smooth and efficient manner. [0003] Using a stackable switch allows network administrators to build systems with multiple physical ports connected to diff...
