Multi-homing network system and method for implementing multi-homing network access

Abstract

The invention provides a method for realizing multi-homing network access and a multi-homing network system, particularly being: distributing identity IP address incapable of routing for a host in multi-homing network; when the host is accessed as the source host, the source host takes the self identity IP address as the grouping source address, the IP address of the obtained destination host as the grouping destination address and sends the grouping; in the sending process, the grouping source address is converted into the position IP address capable of routing applying in the access ISP previously to realize access. By applying the proposal of the invention, as uniform address conversion server is set and the identity IP address incapable of routing for all hosts, and if the access ISP varies, the identity IP address of the host can keep still , the position IP address corresponding to the identity IP address in an address server is modified, thereby greatly reducing the configuration workload of IP address and strengthening the transportability of address.

Description

technical field [0001] The invention relates to multi-homing network technology, in particular to a method for realizing multi-homing network access and a multi-homing network system. Background technique [0002] Customer networks at the edge can access the Internet through an Internet Service Provider (ISP). In order to improve the reliability of the customer network's own connection and enhance the ability of redundancy protection, the customer network can enjoy the connection services provided by multiple ISPs at the same time. In this way, when the customer's network accesses the Internet through a certain ISP and fails, the session path can be changed and another ISP can access the Internet. The customer network described here that can simultaneously enjoy connection services provided by multiple ISPs is generally called a multi-homing network. [0003] Both the Internet Protocol Version 4 (IPv4)-based Internet and the Internet Protocol Version 6 (IPv6)-based Interne...

Problems solved by technology

[0005] However, since the IP address applied for from the ISP is directly configured in the host of the customer network, if the access to the ISP changes, the customer network needs to re-apply for an IP address from the new ISP, and configure the IP address for each host in the customer network. The configuration of the new IP address is very complicated, and the use of the multi-homing network is not flexible
