Performance evaluation of an AWG based optical router

Data centers are most important and integral part of internet. Now a day's data centers works in collaborative way to solve large-scale problems. The performance of data centers can be further enhanced using fiber optic technology. Routing of data within data centers can be made possible using wavelength routing. Wavelength routing of data can be accomplished by using components like tunable wavelength converters and arrayed waveguide gratings. In routing and buffering optical packet need to be used. This leads to the development of optical switch. In this paper two AWG based switches are compared in terms of physical and network layer parameters, and it has been found that our design outperforms the other recent published design in terms of both physical and network layer parameters. Moreover our design is comparatively more cost effective.
