Method data communication network dividing area and route information diffusion

Abstract

This invention discloses a method for dividing a data communication network and diffusing route information, in which, said data communication network includes multiple NE to be divided into different regions and the NE includes border NE, the method includes: configuring ports of said border NE in terms of domain ID, when a change happens to the route path in a domain, its route information is diffused to outside only when a predefined condition is met, when the route information of a domain in the border NE is changed and the accessibility of the NE is changed, its route information can be diffused to other domains by connecting with ports of other domains connected by said border NE.

Description

technical field

[0001] The present invention relates to DCN (Data Communication Network, hereinafter referred to as DCN) technology, in particular to a method for domain division and routing information diffusion in a data communication network. Background technique

[0002] In the existing DCN operation mode, many operators are accustomed to single-plane networking and single network management, which makes it easy to form a larger DCN network. When the ports of one or several network elements or the connections between network elements When a fault occurs and the routing information of each network element in the DCN changes, since the routing information is broadcast on the entire network and has a large range, it is easy to cause route flapping and route convergence time is too long. Therefore, when the DCN network is large, in order to facilitate the management of network elements by the network management system and limit the propagation range of routing information, i...
