Physical path tracing for IP traffic using SNMP-a comprehensive solution for end-to-end and multicast streams monitoring

Large-scale enterprise IP networks often involve complex topology consisting of routers, bridges and hosts. Due to multiple redundancies and minimized Single Point of Failure (SPOF), sometimes it is difficult to determine the actual path of a packet even with the most up-to-date physical connectivity diagram. This presents a great challenge for troubleshooting end-to-end traffic flows.
