ABSTRACT:
A packet architecture, communication system, and method are provided for determining the location at which a network is disrupted, disabled, and/or severed. The packet can contain control bits and error identification bits which note the location at which disturbance exists, and informs the originating module to take alternative path if necessary. The alternative path can be applied to either re-sending the existing packet or sending future packets between certain modules connected to the network, wherein the network preferably includes one or more ring topologies interconnected with one another between termination devices. The termination devices allow communication across subnets which form an intranet or across a global system, or internet. Although redundant transmission channels are used, each transmission channel preferably does not send redundant packets, nor are the transmission channels dedicated as uni-directional. Instead, each of the redundant transmission channels can send dissimilar packets in a bi-directional fashion.
