Network Topology Discovery Based on SNMP

This paper proposes a network topology discovery algorithm and detailed implementation process. The paper introduces several kinds of centralized discovery technologies for network topology, and puts forwards a network topology discovery improvement algorithm. In the algorithm implementation, the authors independently design a software development kit (including encoding, decoding, network operation, etc) and use asynchronous multi-threaded method. In the real campus network environment, the experimental results show that the method has obvious advantages on time and flow than commercial software SNMPc.
