Simple Multiplexing Headers for the JRMP Stream Subprotocol

This article deals with a simple optimization for a level-5 protocol called JRMP (Java's Remote Method Protocol), which is used in a distribution model named Java's RMI (Java's Remote Method Invocation). The main JRMP subprotocol, namely Stream, has been enhanced with a simple and direct multiplexing mechanism that offers the possibility of transferring several parallel request-response interactions without opening new TCP/IP connections. The overhead required to process headers and the advantages stemmed from the approach in terms of response-time are explored on a switched-ethernet benchmark application.
