AN ALGORITHM OF REAL-TIME NETWORK TOPOLOGY DISCOVERY FOR NETWORK SITUATION AWARENESS

For network situation awareness system, the importance of real-time network topology discovery lies in providing a platform displaying real-time network situation. In this paper, an algorithm of real-time network topology discovery based on SNMP and several techniques are proposed including confirmation of network device' activity, distinguish of network device's type, storage and disposal of network topology information and so on.. In the given experiment environment, the algorithm is validated to prove that it is feasible and accurate.
