We present a SNMP-based topology discovery algorithm using direct connection theorem and simple connection theorem for judging relationship of switches in subnets. In order to in discover the map of network without SNMP, several key problems such as subnet guessing and multi-address routers are discussed in details. And then a topology discovery algorithm based on primitive protocols is presented. We also deeply study some routing protocols such as OSPF and BGP and propose a routing-protocols-based algorithm for topology discovery.
