A Complete Topology Management Mechanism for the Advanced Switching Interconnect Technology

The advanced switching technology is a new high-performance standard serial inter-connect. Its specification establishes a management infrastructure in charge of maintaining the fabric operation after the occurrence of a topological change. When the change is detected, the management mechanism discovers the new topology, obtains a set of fabric paths, and finally distributes them to the endpoints. The main contribution of this paper is a completely functional mechanism that implements all these management tasks involved in handling topological changes in source routing switched networks, as advanced switching. We also analyze the behavior of this first proposal, in order to identify its bottlenecks and define future improvements.
