ABSTRACT
PPSN(PERSONAL PUBLIC SERVICE NUMBER )
The current fast growing internet traffic is demanding more and more network capacity everyday. As telecommunication and computer communications continue to converge, data traffic is gradually exceeding telephony traffic. This means that many of the existing connection-oriented or circuit-switched networks will need to be upgraded to support packet-switched data traffic. The concept of wavelength division multiplexing has provided us an opportunity to multiply network capacity. Current photonic switching technologies allow us to rapidly deliver the enormous bandwidth of wavelength division multiplexing networks. Of all switching schemes, photonic packet switching appears to be a strong candidate because of high speed data rate/format transparency, and configurability it offers. The goal of this paper is to discuss some of the critical issues involved in designing and implementing photonic packet switched networks. Finally, we conclude by describing some of the emerging technologies with the potential to revolutionize optical packet switching.
