The design of a high speed, broadband packet switch with two priority levels for application in integrated voice/data networks is presented. The packet switch can efficiently cope with 128 byte packets converging on it from eight 140 Mbit/s dynamic time division multiplexed fibre optic links. The packet switch throughput varies with the load and traffic composition, and the delay experienced by voice and data packets is within 300 μs and 3 ms, respectively. The design is implemented by task-sharing in a multi-processor configuration. The design of the packet switch, including its subsystems, is detailed here. © 1989.

Proposed high speed packet switch for broadband integrated networks

Computer Communications

This paper proposes a packet switched broadband integrated network, for multi-rate services such as voice and data. A novel design of a high speed packet switch capable of catering to voice and data traffic is described. Some sources of traffic bottle-necks are identified, and methods of clearing the bottle-necks through flow control techniques are discussed. The design and flow control parameters are obtained through simulation, and the results are presented. The performance of the network and the packet switch is evaluated for various traffic characteristics through a second simulation, and the results are briefly presented. © 1992.

The design and flow control of a high speed, integrated, packet switched network

Several of the high speed optical fibre Metropolitan Area Networks proposed in recent years are slotted networks using deflection routing [1]. Manhattan Street Network is amongst the simplest of these with an underlying Manhattan graph. We propose to place highways in the Manhattan street network. This significantly reduces the delay in the case where packets have to travel long distances. With the reduced delay, the network can better support multiple services like packetised voice in addition to data communication. © 1991 SPIE. All rights reserved.
