Design And Implementation Of Enterprise Instant Messaging System

This paper focuses on the Instant Messaging System (IMS), which describes howto support larger users online of the system by the scalable architecture design, so thatthe system code has better scalability, and also tells about the definition and functionof the realization of Instant Messaging Protocols. There is a thorough understandingof IMS by describing the scalable architecture and scalable code, which further knowsmore details about its inside modules by the introduction of core module protocols.The innovation of this paper is about the enterprise-class IMS, of how to realizethe scalability of the system. The scalability consists of two aspects:(a) the scalabilityof function, which is realized through module and plug-in architecture. The moduleenables the division of system functions becoming clearer, and the plug-in system canextend the functionality without shutting down the system.(b) the scalability ofsystem users on the line number, by the way of horizontal scalability. Horizontalscalability is expanded by adding a new physical host, not by the system scale-up.With the increasing number of users and new features, the scalability of system andcode will be incorporated into the system design. The scalability design andimplementation details of IMS in this paper, provides certain reference value for thosedesign and implementation similar to this network.
