CREATING BALANCED LINK-DISJOINT TOPOLOGIES IN A COMPUTER NETWORK

摘要

In one embodiment, each node in a computer network determines a shortest looping ring back to the node through each of its neighbors. Each of these rings may then be marked in a particular direction, ensuring that any ring that shares a link with another ring is marked in such a way that the shared link is in the same direction in each of the rings that share the link. The links that are marked in the particular direction may be stored as part of a first topology. Conversely, the opposite direction on the links (e.g., bidirectional links or parallel unidirectional links) may be stored as a second topology that is link-disjoint from the first topology.
