Abstract
A credit loop that produces a deadlock is identified in a network of switches that are interconnected for packet traffic flows therethrough. The identification is carried out by periodically transmitting respective credit loop control messages from the loop-participating switches via their deadlock-suspected egress ports to respective next-hop switches. The CLCMs has switch port-unique identifiers (SPUIDs). The loop is identified when in one of the next-hop switches the SPUID of a received CLCM is equal to the SPUID of a transmitted CLCM thereof. A master switch is selected for resolving the deadlock.
