【摘要】 针对大规模分布式CORBA应用系统存在的服务请求响应的瓶颈问题,在分析系统级和中间级的多线程机制基础上,提出了应用级的动态优先多线程池机制,给出了从先来先服务单线程池到动态优先多线程池方式的处理多请求服务的分配算法,提高了基于Internet/Intranet的分布式应用系统的吞吐量与时间响应性能,并在基于CORBA的异地产品协同设计原型系统中,验证了动态优先多线程池机制的有效性。更多还原

【Abstract】 The throughput and latency of server response are the important performance for large-scale distributed CORBA application systems. In order to solve the bottleneck of CORBA servers, the dynamic priority multi-thread-pool mechanism on the application level is presented. A thread-pool is divided into multiple thread-pools logically. The algorithm to assign requests is introduced so that the client requests are queued dynamically, and this new mechanism is applied in network-oriented products collaborated design prototype system through Internet. The result shows that the response time of server applied in this new mechanism is shorter than other mechanism of one thread-pool in First-come First-serve queue. The throughput of the distributed application system is improved.更多还原
