Component reliability and performance pose a great challenge for interconnection networks. Future technology scaling such as transistor integration capacity in VLSI design will result in higher device degradation and manufacture variability. As a consequence, changes in the network arise, often rendering irregular topologies. This paper proposes a topology-agnostic distributed segment-based algorithm able to handle switch discovery in any topology while guaranteeing connectivity among switches. The proposal, known as Transparent Distributed Segment-Based Routing (TDSR), has been applied to meshes with defective link configurations.
