Some considerations for a high performance message-based interprocess communication system

Abstract

We continue to be concerned with interprocess communications systems (such as those described in references 1, 2, and 3 and called “thin-wire” communications systems in reference 4) which are suitable for communication between processes that are not co-located in the same operating system but rather reside in different operating systems on different computers connected by a computer communications network. Further, the systems with which we are concerned are assumed to communicate using addressed messages (e.g., reference 5) which are multiplexed onto the logical communications channel between the source process and the destination process, rather than using such traditional methods as shared memory (an impossibility for distributed communicating processes) or dedicated physical communications channels between pairs of processes desiring to communicate (which is considered to be prohibitively expensive).
