Modelling and simulation of a large strictly nonblocking fault-tolerant network

摘要

In modern photonic switching systems, a major problem is the creation of large fabrics that often exceed the capacity of a single IC. Moreover, with modern throughput requirements, it becomes important to adopt fault-tolerant architectures characterized by the features of low propagation delay, regularity in structure, fewer links/switching elements in the network and simple switching element design. In this paper the design criteria of a specific large, strictly nonblocking Extended Generalized Shuffle Network, characterized by uniform topology, are presented. For the new network, different network operating modes are indicated and the corresponding performance in terms of fault-tolerance is evaluated.
