Rearrangeable switch fabric for fast packet switching
Computer Communications, 1991Abstract The knockout switch is a switch fabric proposed for fast packet switching. Under certain non-uniform traffic patterns (i.e. a ‘hot spot contention’) the switch exhibits an increase in the packet loss rate. A rearrangeable switch fabric based on knockout switch concepts is proposed which, on the occurrence of ‘hot spot’ traffic, reconfigures ...

Scaling photonic packet switches
2012 14th International Conference on Transparent Optical Networks (ICTON), 2012We consider optical switching architectures that allow for scaling to a large number of ports. We show that the complexity of the node control critically depends on the node architecture and impacts the end-to-end latency of the system. We introduce, node architectures with highly distributed control that allow for systems that introduce very low end ...

The 17th Annual Meeting of the IEEELasers and Electro-Optics Society, 2004. LEOS 2004., 2004
In this talk we will describe the motivation, background and state-of-the-art in optical packet switching architectures, the underlying technology and challenges. Recent optical packet switching demonstration at data rates from 2.5 Gbps to 160 Gbps will be described.

Introduction to Packet Switching
1977The first network developments were an extension of the input-output system of the computer. They acted simply as a distribution network for a central computer. Figure 1 illustrates the forms that they took, in particular the multidrop line and then the concentrator which, by applying some intelligence remotely, can reduce the overhead traffic on the ...

Modeling bufferless packet-switching networks with packet dependencies
Computer Networks, 2009In this paper we present a stochastic network model for packet-switching networks with no buffering capabilities at the nodes. This model can be directly used in the study of all-optical packet-switching (OPS) and optical burst switching (OBS) networks without fiber delay lines (FDLs). Our model provides for the first time a complete description of the

The telephone network is basically a circuit-switched network where a circuit is allocated for the whole duration of the call. This is a satisfactory mode of operation for speech conversation, where the circuit is used more or less continuously by one subscriber or the other.

LANs such as Ethernet and Token Ring provide a high speed connection compared to WANs such as X.25; they allow workstations to communicate at high speed with little delay, creating a seamless environment where the end users are unaware of the supporting network.

We discuss packet switching for single-queue, multi-queue buffers and CIOQ buffers. We evaluate the algorithms by competitive analysis. We also mention the zero-one principle that applies to general switching networks.
