Messaging in distributed systems

摘要

Different middleware technologies have been facilitating the communication between the distributed applications. RMI and CORBA are the most commonly used technology for communication between distributed components. This research work was undertaken in view of increasing e-business requirements. The Transfer of Messages in Distributed Systems (TMDS Architecture) proposed in this paper is based on the concept of asynchronous communication between components. The advantage of the proposed architecture is that the sender of the message can continue processing after sending the message and need not wait for the reply from other application. TMDS Architecture ensures guaranteed delivery of the message. TMDS Architecture supports the two major domain of asynchronous messaging: (ⅰ) Publish/Subscribe and (ⅱ) Point-To-Point domains. In addition TMDS architecture has the facility to prioritize the message, filter messages on certain conditions and the architecture also supports easy integration of new systems with the existing legacy systems.
