TL;DR: The network envisaged is a long-haul, packet-switched network, with optical fibre links between the nodes, for the integrated transmission of voice and data, which effectively utilizes the bandwidth of 140 Mbit/s fibre optic links.
Abstract: Digital transmission through optical fibres and 'packet-switching' are two independent technologies that have gained wide acceptance during the past decade. This paper considers the possibility of a fusion between the two technologies. The network envisaged is a long-haul, packet-switched network, with optical fibre links between the nodes, for the integrated transmission of voice and data. The advantages of implementing packet-switching on an optical fibre network are brought out. The proposed network effectively utilizes the bandwidth of 140 Mbit/s fibre optic links to transport voice and data packets in a store-and-forward manner from the source node to the destination node. The issues involved in the selection of routes for voice and data packets are discussed.

TL;DR: A novel design of a high speed packet switch capable of catering to voice and data traffic is described and the performance of the network and the packet switch is evaluated for various traffic characteristics through a simulation.
Abstract: 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.

TL;DR: Top-down end-to-end user-oriented performance requirements pertaining primarily to voice and digital data services are addressed, and both traditional parameters, as well as contemporary parameters associated with new and evolving systems are considered.
Abstract: This paper addresses top-down end-to-end user-oriented performance requirements pertaining primarily to voice and digital data services. The discussion of requirements for voice parameters accounts for the performance of existing analog and mixed analog/digital networks, as well as the likely effects on performance of short, medium, and long term evolution toward the ultimate all digital ISDN. The requirements for digital data parameters necessarily reflect an evolutionary process which is less consistent than for voice, and therefore these requirements are less definitive in nature. The discussions of voice and digital data performance apply largely to a wide variety of appropriate network designs, transmission schemes, and switching architectures. Both traditional parameters, as well as contemporary parameters associated with new and evolving systems, are considered. The emphasis is on the performance of nation-wide public and private networks, but the paper also considers the constraints of international connections.
