Abstract
A method for preventing loops in a ring topology of a computer network is disclosed. The method includes receiving a packet at a node on a shared packet ring and inserting a header containing an ID identifying the node at which the packet was received on the ring as an originating node. The packet is forwarded onto the ring and the ID is checked when received on a node. The packet is dropped if the ID identifies the node as the originating node.
