Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a method for data communication network domain division and routing information diffusion, which overcomes the shortcomings of the domain division method of the prior art that requires domain setting for each network element, is not flexible enough, and needs to be configured for each network element. Address planning and configuration of network elements, the shortcomings of heavy configuration and maintenance workload, and complex inter-domain routing protocols that do not need to be run on border network elements

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0020] Such as figure 1 As shown, in the method for dividing the data communication network according to the present invention, the network composed of six network elements is divided into two domains, domain 0 and domain 1. NE2 and NE3 are border network elements, and they are During configuration, it is only necessary to configure the domain ID of each port in NE2 and NE3 without involving other network elements. On the border network element NE2, Port1 and Port2 are designated as domain 0, and Port3 is designated as domain 1; on the border network element NE3, Port1 and Port2 are designated as domain 0, and Port3 is designated as domain 1. For border network elements NE2 and NE3, when the routing path in each domain changes, its routing information is only diffused between ports belonging to the same domain, and will not be diffused to other domains,...

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...
