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 path signature. The method further includes generating a second path signature by inputting the first path signature and one or more node details into a hash function. The method includes replacing the first path signature with the second path signature in the packet. The packet including the second path signature is forwarded by the node.
