Further , for the purpose of practice , we implement a simulated cluster system with the remote memory paging system using the trace - driven simulation method 隨后,從實踐的角度出發,進一步采用基于跟蹤的模擬技術實現了一個具有遠程存儲分頁系統的模擬集群。
Using trace - driven simulation , the results show that acr algorithm is better than several traditional algorithms in staleness - hit rate , hence acr algorithm proves to be rational , effective and practical 通過trace d yen4g擬實驗,結果表明acr算法在陳舊命中比上均憂于傳統的幾個替換算法,從而證明了新提出的acr算法是合理、有效和實用的。
( 2 ) the study of load balancing based on web server cluster . the paper outlined the main characteristics , and analyzed the famous scheduling policies for web server cluster in the world . the paper give one improved algorithm on lard , it can better balance the load , and provided a trace - driven simulation . ( 3 ) the paper provided a content - based request distribution , classify web service into two main categories : web publishing ( providing static information and lightly dynamic request ) and web transaction ( providing dynamic content generated from database queries and secure information ) ( 2 )針對web服務器集群負載平衡技術進行研究,總結了web服務器集群負載平衡技術的核心問題;分析了當前的主要請求調度算法,并給出了一種對經典lard算法的改進調度算法,仿真試驗表明改進算法具有良好的適應性;設計了一個基于離散事件仿真的請求調度算法仿真程序用于驗證提出的調度策略。
