Distributed Shared Workspace
Abstract
The objective of the DSW project is to investigate the concept of a collaborative workspace. This workspace should allow large communities of users, working at long distances, to collaborate as effectively as if they are in a single room talking face to face and have access to information regardless of its native location around the world. The objective of DSW is closely related to the field of computer supported cooperative work. While most efforts in that field have concentrated on user interfaces and data structures, relatively little attention has been paid to whether systems incorporating the new features scale well as pans of the system are distributed over various distances, including local area networks and wide area networks. DSW addresses this concern. The results of this project include the following: (1) Identification of special issues in the design and usage of distributed collaborative applications, including the problems of consistency and confidence in the data and decisions managed by such applications, as well as the need to adapt to the varying performance capabilities of the underlying computing resources; (2) Identification of a spectrum of notions for distributed consistency that are applicable to distributed collaborative applications; and (3) Compilation of a set of applicable metrics to describe quality of service in distributed collaborative applications.
