“…On the other hand, taking advantage of this feature requires fast control and wavelength-selective devices, which can dramatically increase the network cost. Photonic slot routing (PSR) was proposed as an alternative to using WDM only as a way to multiply network capacity, thus reducing node complexity and cost, and facilitating network scalability [15]. According to this concept, packets transmitted in the same time slot (photonic slot) on all wavelengths are switched jointly.…”

The current fast-growing Internet traffic is demanding more and more network capacity every day. The concept of wavelength-division multiplexing has provided us an opportunity to multiply networ k capacity. Current o ptic al switching technologies allow us to rapidly deliver the enormous bandwidth of WDM networks. Photonic packet switching offers high-speed, data rate/format transparency, and configurability, which are some of the important characteristics ne eded in fu ture network s suppor ting different forms of data. In this article we present some of the critical issues involved in designing and implementing all-optical packet-switched networks.

“…In an electronic system, contention may be resolved through the use of buffering In the optical domain, however, contention resolution is a more complex issue since it is difficult to implement components that can store optical data. A number of switch architectures that use delay lines to implement optical buffering have been proposed [56]- [59], and a sampling of these approaches will be reviewed below. A delay line is simply a long length of fiber that introduces propagation delays that are on the order of packet transmission times.…”
