Abstract
A system and method for identifying packets in a that may be stuck in a loop includes logically organizing the network as a tree and modifying packets with an artifice to identify the packets intended directionality within the tree. If the actual directionality conflicts with the intended directionality, a potential loop is indicated. The artifice is a flag in the link header, link address, or IP address associated with the packet.
