Abstract:

Computer networks are creating a serious problem increasing numbers of users can access a variety of different information systems. Unlike a set of application programs residing in a single computer, these different information systems have very little in common. They were built for different communities of users, by differing groups of programmers, to run on different hardware configurations, and with very different protocols for manmachine interaction. In addition, the network itself may not be transparent to the user it may require login procedures and access protocols. Networks also can cascade the number of serial components being used to accomplish a task using the ARPANET as an example, one might interact with a remote system via a local host computer, the Interface Message Processor IMP which connects it to the network, possibly several intervening IMPs, the remote host computers IMP, and the remote systems host computer. A failure in one of these components creates the need for rather complex strategies for gracefully backing out of the other systems, preferably leaving some intermediate results intact so that a later restart procedure can be initiated.
