The topology of an ATM network is referred to as the map of the
network consisting of the devices in the network and the
connections among them. Network topology information is useful
for network administration and planning.Entering the network
topology information manually is a tedious task if the number of
network devices is large. Therefore, a tool for generating the
network topology automatically is desirable. In ATMnetworks, the
value of VPI and VCI have only local significance. It does
notexplicitly reveal information about the source, destination,
and path of thevirtual onnection. The source, destination, and
path for a virtual connection can be found by tracing the VPIs
and VCIs in the atm switches.In this paper, algorithms for
discovering the topologies of ATM networks and tracing the paths
of virtual connections automaticallyusing the Simple Network
Management Protocol (SNMP) are proposed.
