【摘要】：針對當前云任務調度算法在密碼云環(huán)境中無法實現(xiàn)任務實時處理的問題,提出一種基于滾動優(yōu)化窗口的實時閾值調度方法。首先,將密鑰調用環(huán)節(jié)融入密碼任務流程中,提出一種密碼云服務架構;其次,為實現(xiàn)任務的實時調度,構建基于滾動窗口的密碼任務調度器模型和吞吐量分析模型,用于獲得實時的吞吐量數(shù)據(jù);最后,為滿足云租戶對高速密碼服務的客觀需求,提出吞吐量閾值調度算法,從而根據(jù)實時吞吐量相對于吞吐量閾值的變化情況實時遷移虛擬密碼機。仿真結果表明,該方法與未采用滾動優(yōu)化窗口或虛擬機遷移技術的方法相比,具有任務完成時間短、CPU占用率低的特點,且實時吞吐量能夠持續(xù)保持在網(wǎng)絡帶寬的70%~85%,從而驗證了其在密碼云環(huán)境中的有效性和實時性。
[Abstract]:In order to solve the problem that the current cloud task scheduling algorithm can not realize the real-time task processing in the password cloud environment, a real-time threshold scheduling method based on rolling optimization window is proposed. Firstly, the key call link is integrated into the password task flow, and a password cloud service architecture is proposed. Secondly, in order to realize the real-time task scheduling, the password task scheduler model and throughput analysis model based on rolling window are constructed to obtain real-time throughput data. Finally, in order to meet the objective needs of cloud tenants for high-speed cryptography services, a throughput threshold scheduling algorithm is proposed to migrate virtual cryptography in real time according to the change of real-time throughput relative to throughput threshold. The simulation results show that compared with the method without rolling optimization window or virtual machine migration technology, this method has the characteristics of short task completion time, low CPU utilization rate, and the real-time throughput can be kept at 70% 鈮，
