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