Abstract
A stale packet removal apparatus and method are provided for a digital processing system of the type having multiple devices that communicate via a plurality of unidirectional rings. Each requesting device sets a traversal count value in a packet and then sends the packet. When the packet is received at an agent, the agent changes the traversal count value and sends the packet onto another of the unidirectional rings. When a device receives the packet, the device identifies the traversal count value and discards the packet responsive to a predefined traversal count value.
