Abstract
Embodiments of the present disclosure include systems and methods for fault detection and recovery over a network. A value of a set of values is stored in packets transmitted during a data transaction between a source and destination. The value corresponds to ports used by one or more switches in the path between the source and destination. The destination includes the value in an acknowledgement packet. Logic circuits in the source device track packets and corresponding values. When a status indicates a particular packet has not received an acknowledgement, the value for the packet may be removed from the set of values. Particular ports that may be congested or down may be detected and the packets re-routed using the logic circuits in the source device.
