为研究混合式P2 P网络中基于文档分区的实时协同访问控制技术，对P2 P网络中的各节点及文档分区资源设置了不同的角色操作权限与资源访问权限，并重点讨论了新节点加入P2 P网络的访问控制。利用基于文档分区的协作小组域划分优势，依照加入节点平均距离与协作小组域平均距离的偏离度判定是否可以加入协作小组域，并在许可新节点加入的同时重新计算小组域内超级节点与备用超级节点，从而提升了协同系统的可靠性，保障了协同小组域间的协同效率。进一步，通过对典型操作实例的分析，验证了该方法的有效性。

A real-time collaborative access control technology based on document partition in hybrid P2P network is proposed, which sets different role’s operating authority and resource access authority for each node and document partition resources. The access control method of adding new node in P2P network is emphatically discussed in the paper. It takes advantage of domain division of cooper-ation group based on document partition and determines whether a node can join in the collaboration group domain according to the deviation degree of average distance between new added node and group domain. In addition, it re-calculates the super node and the backup node in group domain when a new node is allowed to join in the domain, which can improve the efficiency of collaborative editing and enhance the reliability of collaborative systems. This method has been proved to be effec-tive by analyzing typical examples.
