Loop prevention

Abstract:

This disclosure describes techniques for preventing message loops in communications among network devices. The techniques include preventing messages from being returned to a sending node and preventing messages from being sent more than once to any particular node. Such message loops may reverberate among network devices before triage efforts are able to stop the loop. As such, message loop prevention may help decrease the computational load among networked devices. At scale, the techniques may help prevent an exponential increase in data traffic that may propagate widely over the network. Loop prevention techniques may even prevent disabling of a network due to data traffic overload.
