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.

I. INTRODUCTION

The operation of network management system lies on a good command of the topological structure in the whole management network. The auto-discovery of network topology plays a decisive role in network management and function analysis. In this paper, several main network topology discovery technologies are briefly introduced, and then an improved network topology discovery algorithm is presented.
