IP核心网的BGP增量规划

BGP incremental planning in IP core network

BGP协议的研究是目前IP核心网中的一个研究热点,对IP核心网的规划有重要意义。随着网络通信业务的广泛应用,越来越多的通信网络无法满足日益增长的业务需求。除了不断建设新的网络,还需要对旧网络进行改造。而对IP核心网的增量规划的研究对于旧网络向IP核心网的改造具有重要的指导作用。本文首先分析了IP核心网的上BGP协议的组网方式,然后根据BGP协议对IP核心网的层次划分,研究了在IP核心网的核心层、汇聚层和接入层进行BGP增量规划的不同方法,最后通过一个具体的案例来进行验证。

As a hot topic in IP core network, studies in BGP are important to IP core network planning. With the wide application of network communication business, more and more communication network become unable to meet the increasing needs of the business. So apart from the construction of a new network, old network reconstruction is also needed. The study in incremental planning of IP core network would be useful to the transformation from old network to IP core network. This paper first analyzes the BGP networking mode in IP core network, and then various BGP incremental planning methods in the core layer, collective layer and access layer are studied based on BGP level classification in IP core network, at last they are verified by a concrete case.
