University College London ARPANET Project.
Abstract
This report summarises the work at University College London (UCL) on research into, and use of, the ARPA Computer Network. It discusses our activities on connecting hosts and other networks to ARPANET. It discusses our early work on a Packet Satellite Project, and our measurements at a high level of the characteristics of usage via UCL of network hosts. It describes the applications which have benefited from ARPANET during the reporting period. Finally, it discusses an investigation of the techniques for facsimile transmission between different devices over the network. Our earlier work in attacking hosts by front-end techniques has been broadened to provide gateway facilities between computer networks. Here we have pursued two lines. An internetwork Transmission Control Protocol (TCP) has been implemented which is designed to be applicable to a host-host protocol between hosts on different networks. Experiments to test the properties of this protocol have been started between UCL, Stanford U and Bolt, Beranek and Newman (BBN). More effort has been put into designing and implementing gateway functions when a specific node acts as a gateway between two netorks and performs a mapping between the standard protocols of each. We have investigated th applicability of this approach to several networks, including the connection of ARPANET and the UK Post Office Experimental Packet Switched Service (EPSS). Our preliminary results show that the technique should be feasible, but since the other networks are not yet operational, we have not yet demonstrated the technique.
