融合多协议的网络层拓扑发现算法研究

Research on Network-layer Topology Discovery Algorithm Based on Multi-protocol

随着信息技术的不断发展,以及国家对网络空间安全的重视程度越来越高,现有的网络安全产品已经难以满足用户越来越广泛的网络安全需求。通过分析网络拓扑发现对网络安全的重要性,以及现有网络拓扑发现的优缺点,改进原有的网络层的拓扑发现算法,同时改进网络层的OSPF和SNMP拓扑发现规则,实现一种结合SNMP和OSPF共同优点的网络拓扑算法,实验证明该算法取得了不错的效果。

With the continuous development of information technology,and the cyberspace security obtains more and more value,the existing network security products have been difficult to meet the user's demand,which has more and more extensive network security.This paper analyzed the importance of network topology discovery in the area of network security and the advantages and disadvantages of the existing network topology,and improved the original topology discovery algorithm of network-layer.Though improving OSPF and SNMP topology discovery rules of network-layer,a network topology algorithm combining the common advantages of SNMP and OSPF was achieved.Experimental results prove that it has a good performance.
