Message-brokers: a novel interprocess communications primitive

A novel interprocess communication paradigm based on message-passing, called message-brokers, is described together with the small number of language primitives that support message-brokered interprocess communication in C. Message-brokers combine the addressing flexibility of mailboxes with the synchronization facilities of synchronous communication models, such as CSP. Message-brokers are first class data objects. The model directly supports nondeterministic interactions among multiple client and server processes, which are free to move when not communicating. It is also argued that the use of message-brokers is relatively secure and that brokered interprocess communication is well suited to distributed architectures, particularly to closely coupled distributed architectures such as hypercubes
