We design improved approximation algorithms for two variants of the ADM minimization problem. SONET add-drop multiplexers (ADMs) are the dominant cost factor in SONET/WDM rings. T...
This paper compares the performance of hierarchical ring- and mesh-connected wormhole routed shared memory multiprocessor networks in a simulation study. Hierarchical rings are in...
Packet-switching WDM ring networks with a hotspot transporting unicast, multicast, and broadcast trac are important components of high-speed metropolitan area networks. For an arbi...

We present a new multiple ring network for multiprocessors, called the Multistage Ring Network(MRN). The MRN has a 2-level hierarchy of register insertion rings, and its interconn...
