Abstract

Web browser based real time communications applications such as instant messaging, call control and presence aware applications differ from traditional desktop based communications applications. Browser based applications typically rely on Hypertext Transfer Protocol (HTTP) as an application level communications protocol. Traditional desktop applications have used a variety of client/server protocols and techniques. Browser based applications offer many advantages but also introduce many constraints. This paper investigates the possible use of Representational State Transfer (REST) based architectures for real time communications integration systems. We look at REST in the context of an enterprise unified communication system using telephony and presence as representative features of a unified communications system. We contend that a REST based architecture offers benefits for thin clients in a unified communication environment.
