The augmented 3D-tree fault-tolerant network
M. Belkadi, Hussein Talaat Mouftah · 2002
The present paper discusses the design and reliability analysis of the Augmented 3D-Tree Switching network (A3DT). The latter was developed as a result of the vulnerability of the 3D-Tree (3DT) switching network towards certain critical multiple-fault patterns that cause cell loss under a dynamic rerouting scheme even though other fault-free paths might exist. The A3DT network is based on 4/spl times/6 Switching Elements (SE) interconnected in such a way as to enhance the immunity of the 3DT network towards the multiple-fault patterns under consideration; yet without destroying the properties of the underlying network.>
