Problems solved by technology

[0007] The disadvantage of this method is that two independent Ethernet networks are required, which increases the complexity of the actual networking
If you need to connect the device with the redundant node to the router, you need to connect two sets of independent Ethernet to the router. Most of the current router...

Embodiment Construction

[0037] figure 1 It is a schematic diagram of the networking and connection of the active and standby interface line cards in the embodiment of the present invention. As shown in the figure, a separate active Ethernet interface line card 2 is configured in a device 1 that needs to be connected to the Ethernet, as A main Ethernet interface node; and a separate standby Ethernet interface line card 3 as a standby Ethernet interface node. The main interface line card 2 and the backup interface line card 3 are connected through the internal bus of the device to realize data synchronization and information interaction, and externally, they are connected to the same Ethernet switch or hub 4 through separate Ethernet lines at the same time, as shown in the figure , the switch or hub 4 is connected to the wide area network 6 via the router 5 .

[0038] The "line card" mentioned in this article refers to the Ethernet interface line card in a general sense, which can be implemented by a ...

Abstract

The invention discloses an Ethernet interface node backuping method and system, two identical mutual master-backup interface line cards are connected to network exchanger or hub by two independent network cables, respectively; by master-backup competition mechanism, each line card works in a master or backup working state, the master line card receives data through Ethernet port and detects the state of the Ethernet port of its own and answers the hand-shaking information from the backup line card; the backup line card does not receive data, and regularly transmits hand-shaking information to the master line card; when detecting the failure of the port or receiving the switching command, the master line card sends out a switching request and switches to the backup working state at the same time; when receiving the request or detecting the failure of the master line card, the backup line card switches to the master working state. When used in third-generation wireless communication system devices and data communication devices, the invention plays a great role in data transmission stability and reliability and is simple to compose network and has small data flux.

Description

technical field [0001] The invention relates to a backup method and system for Ethernet communication, in particular to a backup method and system for Ethernet interface nodes. Background technique [0002] In the third-generation wireless communication system (3G) and the data communication field, the data transmission between many devices adopts IP-based technology, and Ethernet is used as the interface node during implementation, including 100M Ethernet FE and Gigabit Ethernet GE. If the Ethernet node fails, a large amount of data will be lost for high-speed communication, so it is necessary to backup the Ethernet node. [0003] Currently, there are two main methods to realize Ethernet node backup: [0004] One is to use a physical method to back up the Ethernet port. A Chinese patent application (application number 99117084.9) discloses a main and standby structure of Ethernet ports, including two sets of controllers with the same structure, Ethernet transceivers, tra...
