摘要
In order to support CSCW (Computer Supported Cooperative Work) applications, some basic technologies must be introduced into the computer supported environment. They are shared workspace, work management and interaction among participants. Computer communication is essential and important for these technologies. In this paper, we will discuss different kinds of communication services required by CSCW. There are three communication styles in CSCW support environment: real time stream transfer, real time block transfer and non real time transfer. These communication services require different QoS quality of service parameters. The architecture of QoS is then analyzed and a framework of a QoS guaranteed communication service platform is proposed.
