Improved Distributed Tree Algorithm and It Application in CSCW-Based Group Communication

Based on computer supported cooperative work (CSCW), some basic group communications are discussed. Following the segregated OSI/RM methods, group communication architecture is put forward and the main technology applications are described. A four-layer structure are divided into mainframe and extended routing sub-layer, resource reservation sub-layer, and reliable transmission sub-layer and application support layer. The divisions reflect the relationship between the classifications of group addresses communications services and service functions. Distributed tree algorithm is very important in CSCW, through mathematical deduction, the algorithm is improved to adapt well to the calculation and design.
