Claim 0:
1. A method of validating packet forwarding on multiple paths in a network, the method comprising:
generating, at a first network node, a test data packet with a label to be sent along each of multiple paths in the network between the first network node and a last network node;
forwarding the test data packet from the first network node, along each of the one or more intermediate nodes along each of the multiple paths, to the last network node;
determining a number of packets received at the last network node;
determining whether a number of the multiple paths equals the number of packets received at the last network node;
performing a data plane validation process to validate the packet forwarding from the first network node to the last network node upon determining that the number of the multiple paths equals to the number of packets received at the last network node.
