摘要:

局域网拓扑探测作为网络安全研究的一项重要内容,目前已经很难适应复杂网络环境的需要,存在很多问题亟待解决。在对局域网网络层和物理拓扑探测算法研究的基础上,本文设计并实现了非授权局域网拓扑探测系统Network Probe。该系统以网络层和物理拓扑探测算法为核心,结合了SNMP协议和多种探测方法。测试表明,Network Probe在准 准确性、完整性和探测效率等方面能够满足大规模异构局域网拓扑探测的要求。

Abstract:

As an important research aspect in network security, the Intra-AS network topology probe technology can hardly meet the needs of complex network circu  mstances, and many problems need to be solved. Based on the study of heuristic topology probe algorithms and physical topology probe algorithms, an Intr a-AS network topology probe named NetworkProbe is designed and implemented, its kernel is an heuristic topology probe algorithm and an physical topology probe algorithm, the SNMP-based algorithm and other topology probe techniques are also considered. NetworkProbe can support flexible configuration of p robe policies according to the actual network circumstances. The test results show that NetworkProbe has good performance in correctness, completeness and efficiency, and can meet the requirements of large-scale heterogeneous networks.
