Systems and methods for determining a topology of a network comprising a plurality of intermediary devices and paths

Abstract:

Systems and methods are disclosed for determining a topology of a network comprising a plurality of intermediary devices and intermediary paths. One method includes transmitting probes having a TTL value with a destination set to a destination device; receiving, for each probe transmitted, a response including an IP address of a responding device; determining whether more than one responding device has responded to the probes; determining whether more than one responding device has been found for two previous transmissions of probes when more than one responding device has responded to the probes; and transmitting, for each more than one responding device, probes having a decreased TTL value with a destination set to one of the IP addresses of the more than one responding devices, when more than one responding device has been found for two previous transmissions.
