Hans‐Peter Dommel, Jose Joaquin Garcia-Luna-Aceves · 1995
Abstract { Collaboration in networked multimedia applications requires means to coordinate the activities of a dynamically aggregating set of distributed users, working with various multimedia data on heterogeneous platforms. A oor denotes a control right over a shared resource within a collaborative workspace. Floor control, similar to concurrency control for databases, is gradually being integrated into shared applications to orchestrate the access and dynamic process of joint work on shared data, supporting or substituting a human conference chair. This paper presents a comprehensive view on oor control, analyzing requirements for protocols with respect to the variety of shared tools, describing an architecture to meet these requirements, and nally placing our work in the context of previous e orts.
