Packet switching or optical switching?
IEEE Internet Computing, 2000One of history's main benefits is that it lets us detect trends that help predict the future. Over the past 30 years since the Internet started (1970-2000), many clear trends have emerged. The article very briefly examines the most critical of these trends, the one that led to the creation of the Internet: the packet switching cost trend.

18th International Conference on Advanced Information Networking and Applications, 2004. AINA 2004., 2004
It is difficult for routers to detect if traffic is a dataflow suitable to be mapped to a circuit, or several sporadic packets only being better forwarded respectively. Based on the research of the characteristics of data flows, we introduce new concept, chain-packet, which wrap data into a chain of packets making flow detecting easy; presents a ...

IEEE Global Telecommunications Conference, 1989, and Exhibition. 'Communications Technology for the 1990s and Beyond, 2003
The authors investigate methods of increasing the suitability of packet switching for time-critical, applications (for example, packet video or voice) and of specifying packets that can be discarded in the event of resource exhaustion. They introduce and expand the notion of packet priority and explore the suitability of a number of switch models for ...

Computer Networks (1976), 1976
Abstract In this paper a large common user network for data communications is investigated in an operational environment where about half the traffic was in the form of short messages and the other half was in the form of long ones, where short messages carry the implicit requirement to transit the network with very short time delays.

Publisher Summary This chapter discusses packet switching. Telephone and telex systems use circuit switching. Message telegram systems use message switching, in which a message is sent to a switching center, where it is stored. In message switching, messages longer than 1000 bits are broken up into separate messages or “packets,” hence the term ...

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.

Packet Switching and Replication of Multicast Traffic by Crosspoint Buffered Packet Switches
2007 Workshop on High Performance Switching and Routing, 2007Multicast traffic is expected to increase in packet-oriented networks by the inclusion of broadcast and multimedia-on-demand services. In addition to the high performance for unicast services, combined input-crosspoint buffered (CICB) packet switches have intrinsic properties that are favorable for switching and replication of multicast packets.

Multipriority packet switching on the HYPER switch
1998 IEEE ATM Workshop Proceedings. 'Meeting the Challenges of Deploying the Global Broadband Network Infrastructure' (Cat. No.98EX164), 2002This paper develops an efficient buffer management scheme that makes generic ATM switches capable of supporting delay-sensitive as well as loss-sensitive traffic. The proposed scheme aims at enhancing the performance of ATM switches by maintaining the head cells of output queues in relatively short dedicated output buffers, while maintaining the long ...

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 ...
