<p>A device, method, system and computer program product for implementing a simplified shortest path routing schema in a shared access ring topology (100) is provided. The present invention allows the routing of data packets on a bi-directional ring (100) by monitoring data from only a single direction of the ring (100). Yet, by implementing a two-phase approach and utilizing the TTL field (TTL) within packet headers, in an embodiment, a decision on which of two paths should be chosen as the shortest path in the ring topology can still be made.</p> |
