Dynamically Reconfigurable Optical Buffer and Multicast-enabled Switch Fabric for Optical Packet Switching

A Dynamically Adaptive Switching Fabric on a Multicontext Reconfigurable Device

A framework of dynamically adaptive hardware mechanism on multicontext reconfigurable devices is proposed, and as an example, an adaptive switching fabric is implemented on NEC’s novel reconfigurable device DRP(Dynamically Reconfigurable Processor). In this switch, contexts for the full crossbar and alternative hardware modules, which provide larger bandwidth but can treat only a limited patter...

Design of Arrayed Waveguide Grating based Optical Switch for High Speed Optical Networks

This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...

Planar Optical Space Switch Architectures

Optical space switches are important subsystems in optical crossconnects (OXCs) and reconfigurable optical add/drop multiplexers (R-OADMs), while also having applications in more long-term communications scenarios, such as optical packet switching. This chapter develops the theory of operation of planar optical space switches, and illustrates the interrelationship that exists between device cha...

Fast Reconfigurable Crossbar Switching in FPGAs

Field Programmable Gate Arrays (FPGAs) and reconfigurable crossbar switches currently represent distinct classes of integrated circuits. There is a need, however, for user-programmable devices that can provide both digital logic and fast, reconfigurable crossbar switching of digital signals within a single package. An investigation into the use of dynamically reconfigurable FPGAs for this purpo...
