AWG Based Optical Packet Switch Architecture

چکیده
This paper discusses an optical packet switch (OPS) arch itecture, which utilizes the components like optical reflectors, tunable wavelength converters (TWCs), arrayed waveguide grating (AW G) and pieces of fiber to realize the switching action. This architecture uses routing pattern of AW G, and its symmetric nature, to simplify switch operation significantly. It is also shown that using multiwavelengths optical reflector, length of delay lines can be reduced to half of its original value. Th is reduction in length is useful for comparat ively larger size packets as for them. It can grow up some kilometers. The considered architecture is compared with already published architecture. Finally, modifications in the architecture are suggested such that switch can be efficiently placed in the backbone network.

This paper analyzes the packet loss and delay performance of an arrayed-waveguide-grating-based (AWG) optical packet switch developed within the EPSRC-funded project WASPNET (wavelength switched packet network). Two node designs are proposed based on feedback and feed-forward strategies, using sharing among multiple wavelengths to assist in contention resolution. The feedback configuration allo...
