Towards efficient packet switching metro WDM networks

Packet Switching Performance of WDM

In this paper, we analyze the performance of a packet-switched broadcast-and-select all-optical network with N nodes and W wavelengths. We model the network as an N N space-division time-slotted packet switch. Each input port has a buuer to store incoming packets until they are switched. In each time slot, a set of W ports is selected to transmit their head-of-line (HOL) packets. We consider th...

Design and Optimization of Packet Switching and Traffic Grooming in Wdm Optical Networks

Optical packet switching is a long-term strategy to provide high-speed transmission, data transparency, and reconfigurability. Optical buffers are used in the switches to resolve contentions that occur whenever two packets are destined to the same output at the same time slot. Due to the lack of optical random access memory, fiber delay line (FDL) is currently the only way to implement optical ...

A Contention-Free Tbit/sec Packet-Switching Architecture for ATM over WDM Networks

Future high-speed switches and routers will be expected to support a large number of ports at high line rates carrying traffic with diverse statistical properties. Accordingly, scheduling mechanisms will be required to handle Tbit/sec aggregated capacity while providing quality of service (QoS) guarantees. In this paper a novel high-capacity switching scheme for ATM/WDM networks is presented. T...

Design of optical packet switching networks

The technological evolution of telecommunication networks in recent years has shown that the availability of transmission bandwidth has been growing at a faster pace than the STNitChing bandwidth inside network nodes [4]. This means that in the near future electronic switching will become the perfonnance bottleneck of high-capacity networks. The cost of a Switching device (be it an IP router, a...
