Device for realizing dual-backup switching of Ethernet link inside communication equipment
2011
The invention discloses a device for realizing dual-backup switching of an Ethernet link inside communication equipment, belonging to the technical field of product structures of devices for mainly realizing dual-backup of internal network links by systems in a communication technical equipment product. The device for realizing dual-backup switching of the Ethernet link inside the communication equipment comprises at least one main control mother plate, at least one main control opposite plate, at least one back plate and at least one business plate, wherein a structure, in which the main control mother plate and the main control opposite plate are in a dual-backup relation in whole device, control flow analysis and business flow direction control are mainly finished and only one main control plate is in a primary state while the other one main control plate is in a standby state at any time, is formed. By using the device disclosed by the invention, a fast switching effect can be realized on the basis of reducing the wiring difficulty and cost of the back plate and the business plate while the main and standby backups are switched.
