Ethernet switch system

Abstract

The invention relates to an Ethernet switch system. The Ethernet switch system comprises a shell and a transmission interface arranged at the end part of the shell, wherein the shell is internally provided with a port aggregation chip, a power module and a relay conduction device; the port aggregation chip is connected with a CPU (Central Processing Unit) and the power module installed in the shell, and is used for realizing the port aggregation of a switch after starting the switch; the relay conduction device is connected with the power module and is used for keeping a line of the switch to be connected when the switch cannot work normally; the port aggregation chip is connected with the power module. The Ethernet switch system provided by the invention increases the network bandwidth and saves a lot of cost for users to choose ten-gigabit switches; besides, the switch system is configured with the relay conduction device to realize equipment redundancy; when the equipment is failed, corresponding ports are directly conducted to make the network to skip over the failed switch, therefore the problem that the whole system cannot run due to the failures of partial switches can be solved.

Description

technical field [0001] The invention relates to the technical field of Ethernet data backup, in particular to an Ethernet switch system. Background technique [0002] At present, in the Ethernet switch system, a ring network structure is commonly used to realize link redundancy and device redundancy of the switch system, such as the ring network structure disclosed in Chinese patent application No. 201010162067.7. This ring structure is as figure 1 As shown, it mainly selects the master-slave switch through the algorithm and determines the normal link and the backup link, judges the communication status of the port through interruption and polling monitoring, and realizes redundancy by changing the port status. Since the switches in the ring network structure only communicate through one network cable, they can only provide a maximum network bandwidth of 1000M. If there are multiple link failures, redundancy cannot be achieved. Moreover, its CPU performs high-speed real-tim...

AI Technical Summary

Problems solved by technology

Since the switches in the ring network structure only communicate through one network cable, they can only provide a maximum network bandwidth of 1000M. If there are multiple link failures, redundancy cannot be achieved. Moreover, its CPU performs high-speed real-time calculations, and its own contracting takes up a large amount of the network. Resources, once its CPU hangs up, it will cause the whole network to be paralyzed
