网络环境下协同设计的多服务器技术

提出了一种分布式客户枳／多服务器系统结构，通过有效的多服务器冲突协商机制实现由多台网络服务器对协同设计用户的联合管理，避免协同过程对单一服务器的依赖，克服了单服务器系统的瓶颈，提高了协同设计过程的稳定性和可靠性．提出了一种基于排队理论的具有多服务器的客户／服务器系统的数学模型，通过分析求解服务器平均利用率、排队队长、等待时间等系统性能的解析结果，方便、直观地反映系统的动态行为，合理地组织系统、优化多服务器系统的设计．

Multi-server Technology for Internet-based Collaborative Design

A distributed Client/Multi-Server system is developed, in which the multi-server system controlled the collaborative clients by the mechanism of collision arbitration. This is made to avoid collaborative clients to become completely dependent on the single server and to improve the stabilization and reliability of the server system. A mathematic model of multi-server system based on queuing theory is presented. The solution of mathematic model is analyzed, which includes the average utilization frequency of servers, the length of queuing and waiting time. The theory system, which is intuitionistie and convenient, is redounded to reflecting the dynamic data change of the system, reasonably organizing the system and optimizing the design methodology of the multi-server system.
