Communication method and device for network element group network

Abstract

The invention provides a communication method and a communication device for a network element group network. The method comprises that: a command switch in the network element group network informs member switches added into the network element group network of enabling an Internet protocol version 6 (IPv6) stateless automatic configuration function, and generates and maintains IPv6 addresses comprising the media access control (MAC) address information of the member switches for the member switches; each member switch in the network element group network communicates with the other member switches or with the command switch by the IPv6 address; and the command switch realizes communication between the member switches and an external network by performing network address translation (NAT) on an IPv4 public network address of the network element group network and the IPv6 address of the member switches. By the method and the device, management over a network element group can be simplified.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a communication method, system and device for a network element group network. Background technique [0002] Network element group management is a dedicated private protocol group for the same configuration, maintenance and management of a group of Ethernet products for the problems of large amount of equipment configuration and maintenance, serious waste of IP resources, and poor openness. When managing a large number of switches, in order to save IP addresses and facilitate management, the network element group management function is introduced. [0003] Such as figure 1 As shown, switches in a network element group can communicate with each other, and each switch is mainly divided into two roles: a command switch and a member switch. The command switch is configured with an IPv4 public network address, and the command switch realizes the configuration a...

AI Technical Summary

Problems solved by technology

[0005] It can be seen that in the prior art, the command switch needs to allocate different IPv4 private network addresses to each member switch in the network element group network, and the command switch needs to maintain the IPv4 private address of each member switch in the network element group network. The mapping relationship between the network address and the MAC address, obviously, the management of the network element group is very complicated
