See full text

A system receives a packet at a router, and pushes a label onto a label stack. The label stack is associated with the packet. The system provides a forwarding record containing label bindings for the router, and transmits the forwarding record to a collector. A system receives a forwarding record from a router. The system compares a first record entry type of the forwarding record with a second record entry type of the forwarding record to determine the traffic flow in the network. The system then maps the traffic flow in the network, based on a result of the comparing.
