Abstract
In the scenarios of multi-protocol cooperative networking,discontinuous structure networking and security equipment net-working,the current network topology discovery technology has many problems such as lack of topology integrity and poor protocol adapt-ability.In this paper,a multi-protocol network topology construction method based on x-neighbors algorithm is proposed.This method completes the complete process of network topology construction through three core steps:First,OSPF,BGP and other routing protocols are modeled,and SSH,SNMP protocol acquisition information and Syslog analysis log are integrated.At the same time,routing informa-tion,LSDB and other multi-source data are obtained to build a dynamic basic topology information database;secondly,based on the x-neighbors algorithm,the corresponding parameters are extracted,and the IP coding sorting technology is used to complete the integration and unification of the protocol heterogeneous data,so as to generate a unique and regular topology database.Finally,the construction of network topology is completed through number transformation.After experimental testing,the method has a topology discovery integrity rate of 98.7%and a node identification accuracy rate of more than 98.5%in a multi-protocol networking environment with security devic-es,which can effectively solve the topology island problem in the network.It provides efficient,safe and reliable topology management technical support for the operation and maintenance of medium and large networks.关键词
