The Design of Automatic Network Switcher of Gigabit Ethernet Switches
This paper investigates the technique of network access switch between host-gigabit-Ethernet-switch and backup- gigabit-Ethernet-switch,and proposes an automatic,security,stable and high reliability switching method adopting high- frequency relays.The new method uses the following strategy.If the host-gigabit-Ethernet-switch works properly,the automatic network switcher is powered off,the automatic network switcher is directly connected with the host-gigabit-Ethernet-switch since the high-frequency relays works in the closed state,thus this condition is normal state and has very high reliability; while the host-Ethernet-switch works improperly,the remote-network switcher-control-terminal detects the switching state between the host-Ethernet-switch and the backup-Ethernet-switch,then it makes the automatic network switcher powered on through LAN,and controls the automatic network switcher to complete switching operation with the high-frequency relays working in the open state,so the automatic network switcher will be connected with the backup-gigabit-Ethernet-switch.Adopting such strategy,we have developed a prototype automatic network switcher of gigabit-Ethernet-switches,and test results show that the proposed automatic network switcher has achieved very good performance.The proposed scheme can be widely used in high reliability communication network.
