Door : Real - Time Communication Middleware

Communication Door: Real-Time Communication Middleware By Masahiro TABUCHI,* Kazuaki NAKAJIMA,* Akiko KAWAMOTO,* Takashi OSHIBA* and Shujun YOSHIZAKA* We describe a real-time communication middleware system that enables solution providers to construct various applications, such as web conferencing systems and IP-based call centers. The middleware platform, called Communication Door, is a web-based application platform for real-time groupware. It includes a real-time web sharing function implemented with an HTTP-based push protocol and an audio-video communication function. By using this middleware, many real-time groupware applications can be customized by rewriting their designs and functionalities through a server-side web application while utilizing thin clients. Solution providers can customize the user interface design and the functions of real-time groupware by revising their server-side web applications. In this paper, we describe the architecture of the middleware and its applications.
