Backup method for Ethernet port connected to Internet protocol network

Abstract

The invention is a method for backuping the Ethernet port accessed to IP network. It sets at least two blocks of IP repeat board as the main backup board in the exchanger, each board has a port accessing to the IP network, all the Ethernet ports are initialized with a same IP address and MAC address, then controls the main backup board, uses the main board to carry on the reception and transmission of IP network information, the backup board doesn't receive the information from the IP network, the IP package is sent to the main board at first through inter-board communication, and then they are sent to the IP network through the main board. When carrying on the convert of backup board and main board, the new main board sends out an address resolution protocol (ARP) for gateway device. The invention provides a simple backup method of Ethernet ports between boards, it saves the running cost, and it can realize the smooth conversion.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for backing up an Ethernet port connected to an IP network. Background technique [0002] At present, products such as program-controlled switches need to provide IP interfaces to provide external IP services such as EPHONE (Ethernet Telephone). Perform Ethernet port backup. [0003] Such as figure 1 The schematic diagram of the realization principle of EPHONE (Ethernet telephone) service is shown. The IP network port of the EPHONE phone is connected to the IP network (such as a metropolitan area network, which can be accessed through the media gateway MG). At the same time, the program-controlled switch is also connected to the IP network port. To the IP network (such as a metropolitan area network, which can be accessed through a LAN switch and router), the EPHONE phone and the switch achieve intercommunication through the Media Gateway Control Protocol (MGCP),...

AI Technical Summary

Problems solved by technology

[0015] The technical problem to be solved by the present invention is to provide a simple and practical method for backing up Ethernet ports between boards by overcoming the disadvantages of inconvenient switchover, high cost or high equipment requirements for existing Ethernet port backup schemes connected to IP networks, It can not only reduce the requirements for equipment, but also save operating costs. When the Ethernet port fails, it can realize smooth and fast switchover of the network port
