Abstract

Systems, methods, and computer-readable media are disclosed for validating multiple paths used for routing network traffic in a network. In one aspect, a network controller can identify one or more intermediate nodes on each of multiple paths in a network, wherein the multiple paths begin at a first network node and end at a last network node. The network controller can further generate a data packet with a label at the first network node, forward the test data packet from the first network node, along each of the one or more intermediate nodes, to the last network node, and perform a data plane validation process for validating packet forwarding from the first network node to the last network node based on the label(s) by determining if a number of the multiple paths equals to a number of packets received at the last network node.
