摘要:
文中在分析智慧城市建设中解决异构系统资源共享重要性的基础上,提出一种基于企业服务总线(ESB)的共享平台架构模型,并以“贵阳市城市综合应急管理共享平台”为例探讨了该共享平台的实现方案.为了在复杂企业应用集成环境中,能够高效率、实时地实现各部门间信息的共享,提出了基于PQ(优先级队列,Priority Queueing)算法和DWRR(赤加权轮询,Deficit Weighted Round Robin)算法的改进算法P-DWRR.实践表明,该算法能够使得该共享平台在大量用户并发使用时,依然保持较高的共享效率,避免有些用户请求长时间得不到回应的问题
Abstract:
Based on the analysis of the importance of resources sharing between heterogeneous systems in the intelligence urban construc-tion,an shared platform structure model based on enterprise service bus (ESB) is proposed,and use an example,“Guiyang city compre-hensive emergency management sharing platform”,to discuss the implementation of sharing platform. In order to complete information sharing between various departments efficiently in real time,put forward P-DWRR algorithm based on the PQ (Priority Queueing) algo-rithm and the DWRR (Deficit Weighted Round Robin). Practice shows that under a large number of concurrent users,this algorithm maintains high efficiency of the sharing and avoids some requests time without response for a long
