We demonstrate a Colorless, Directionless, and Contentionless add/drop that is made possible by newly proposed multistage tunable filters; it will be effective in the creation of flexible and dynamic optical path networks. The filters consist of small-scale switches and AWGs (Arrayed Waveguide Gratings) and so are cost effective. The technical feasibility of the drop configuration using propose...

Interconnection networks are constructed to provide inter-process communication. These Networks are compared on the basis of Fault tolerance, Reliability, Path length and cost effectiveness. An irregular class of Fault Tolerant Multistage Interconnection Network (MIN) called Modified Four Double Tree Network-2 (MFDOT-2) is proposed.MFDOT-2 is constructed on the basis of FDOT-2 [1]. The Reliabil...

Parallel processing is an efficient form of information processing system, which emphasizes the exploitation of concurrent events in the computing process. To achieve parallel processing it’s required to develop more capable and costeffective systems. In order to operate more efficiently a network is required to handle large amount of traffic. Multi-stage Interconnection Network plays a vital r...

While multistage switching networks for vector multiprocessors have been studied extensively , detailed evaluations of their performance are rare. Indeed, analytical models, simulations with pseudo-synthetic loads, studies focused on average-value parameters, and measurements of networks disconnected from the machine, all provide limited information. In this paper, instead , we present an in-de...

Multistage interconnection networks are frequently proposed as connections in multiprocessor systems or network switches. In this paper, a new tool for stochastic simulation of such networks is presented. Simple crossbars can be simulated as well as multistage interconnection networks that are arranged in multiple layers.
