Abstract:
The present invention provides a method and apparatus for removing unwanted data packets from a ring topology communication network having a plurality of nodes. The invention ensures that a data packet is removed from the network if there is a failure of the originating node, or if there is a failure of the node principally responsible for removing the data packet. The invention provides fault-tolerance, without significantly adversely affecting the overall network performance. The invention provides the originating node address in a controlled field of the data packet, with unused data bits within the control field being used as "rouge packet bits. " The invention will include one or more nodes designated as "rouge data packet removal nodes" or "rouge removal nodes. " A data packet is created at an originating node which will embed its own address in a "Node ID" field of the data packet and will transmit the data packet along the network. The invention enables rouge data packets to be detected and removed from the network.
