Abstract

Advanced Switching Interconnect (ASI) is a new high-performance serial interconnect. In order to support high availability, its specification establishes a management infrastructure, which is in charge of maintaining the network operation after the occurrence of a topological change. During the change assimilation process, a management mechanism must discover the new topology, obtain a set of paths, and finally distribute them to the fabric endpoints. Recently, an implementation for this mechanism has been proposed, in which a management entity performs all the previous tasks in a centralized way. In this paper, we propose a distributed solution for computing the new set of paths, with the aim of reducing the negative impact on the network service of the centralized proposal.
