Cost/Benefit Analysis of Computer Based Message Systems

This article provides a review and synthesis of the recent literature in computer based message systems (CBMS). It describes the problems associated with the current methods of communication and discusses how CBMS attempts to solve these problems. The article then presents some estimates of the costs of CBMS and potential problems that could slow down the implementation f these systems. The art...

Proposed Federal Information Processing Standard: Specification for message format for computer based message systems

Fault-tolerant Message Routing in Computer Networks

We are considering a problem of faulttolerant wormhole unicast routing in computer networks, consisting of nodes (processor units), connected by bi-directional links. Each node can be viewed as the combination of a router and a processor with some RAM, bus and I/O circuitry. We concentrate on networks with arbitrary (irregular) topologies. The problem of routing in the presence of faults is div...

Message Queuing Systems

Definition Amessage is an information sent by a sender process to a receiver process. A message queue is a mechanism that allows a sender process and a receiver process to exchange messages; the sender posts a message in the queue, and the receiver retrieves the message from the queue. A message queuing system provides a mean to build distributed systems, where distributed processes communicate...

Computer-Aided Programming for Message- Passing Systems: Problems and a Solution

As the number of processors and the complexity of problems to be solved increase, programming multiprocessing systems becomes more diff icult and error-prone. Program development tools are necessary since programmers are not able to develop complex parallel programs efficiently. Parallel models of computation, parallelization problems, and tools for computer-aided programming (CAP) are discusse...
