The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

A Communication System Supporting Large Datagrams on a Local Area Network

Abstract

This paper describes an implementation of a software interface designed for use from within UNIX application programs for network communications. Thsi interface provides the abstraction of possibly very large datagrams supports ""scatter-gather"" facilities, and maintains standard network addresses consisting of pairs. This interface has been provided on different data communication facilities allowing uniform program access to those facilities. The particular implementation developed for a local area network is described and performance results obtained are examined and compared with those obtained from a conventional datagram interface to that network. The results obtained confirm that the abstraction of very large datagrams enables the construction of an efficient mechanism for process-to-process communications over the network that is not only more convenient, but also has significant performance advantages over the use of conventional (small) datagrams.
