Publisher Summary This chapter describes packet switching. Packet switching is a mature, secure method of transferring data across a network. It divides data into segments, each of which is wrapped in an envelope to form a packet; a typical message comprises one or more packets. Each packet contains the actual user data plus information helpful to its

37th European Conference and Exposition on Optical Communications, 2011
The capacity growth of optical networks and a transition towards packet-based traffic has motivated research on optical packet switches. We review recent experiments on optical packet switches and their application to metropolitan and core networks ...

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 ...

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.

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.

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 ...

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 evolution of packet switching
Proceedings of the IEEE, 1978Over the past decade data communications has been revolutionized by a radically new technology called packet switching. In 1968 virtually all interactive data communication networks were circuit switched, the same as the telephone network. Circuit switching networks preallocate transmission bandwidth for an entire call or session.

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 ...
