Abstract


With the merging of computer network technology and communication technology , computer support based on these two technologies work together ( Computer Supported Cooperative Work of CSCW ) technology, has been the rapid development . The traditional collaborative framework widely used model of client / server (C / S) , In this architecture , the overall operation of the system to some extent by the limitations of server performance , load Center Server node system often become bottlenecks and poor scalability . At the same time over a single structure , making the system unable to meet the special requirements of different applications , such as streaming media synergy requires high synchronization and low latency , and the sharing of resources you need to ensure that the system network load balancing . The development of P2P technology gradually changed the way people communicate . P2P network so that each user both as a client and as a server , and greatly improve the utilization of each node , reducing the load of the entire network . Therefore , the P2P network is used in collaborative research collaborative P2P model - based architecture , has important research significance and application value . Design a double-layer hybrid P2P model - based collaborative framework , which combines the transmission tree structure and structured backbone network structure of the local group , the structure of the backbone network is a key nodes returned by each local group . Through simulation and analysis , proved this double hybrid structure has better scalability , robustness and load balancing capabilities . Collaborative architecture design , the key node is used to contact the local group and the backbone network , and thus play a very important role . The local group , the key nodes save information of each member node , and so create a tree structure is passed . The establishment of the transmission tree , the different application needs , according to the actual establishment of a different tree structure . Backbone network to take a structured model , to make up for the defects of the the single transmission tree structure on the scalability . The realization of this collaborative framework , to make full use of the advantages of P2P network to achieve a safe , efficient, stable collaborative application environment .
