Abstract

This disclosure describes various methods, systems, and devices related to identifying path changes of data flows in a network. An example method includes receiving, at a node, a packet including a first signature. The method further includes generating a second signature by inputting the first signature and one or more node details into a hash function. The method includes replacing the first signature with the second signature in the packet. The packet including the second value is forwarded by the node.
