【摘要】：動(dòng)環(huán)監(jiān)控系統(tǒng)是機(jī)房穩(wěn)定運(yùn)行的保障。目前云計(jì)算被運(yùn)用于動(dòng)環(huán)監(jiān)控系統(tǒng),以管理監(jiān)控大面積的分布式機(jī)房。隨著社會的快速發(fā)展,越來越多的廠家開始架設(shè)自己的機(jī)房,機(jī)房密度和分布面積迅速增長。而分布式云架構(gòu)隨服務(wù)器節(jié)點(diǎn)數(shù)量擴(kuò)張,云服務(wù)系統(tǒng)消耗呈指數(shù)型上升,限制了其擴(kuò)張能力。為了增強(qiáng)系統(tǒng)的擴(kuò)張能力,本文提出了將邊緣云架構(gòu)應(yīng)用于動(dòng)環(huán)監(jiān)控系統(tǒng)。邊緣云架構(gòu)是在分布式云架構(gòu)的基礎(chǔ)上增加了一臺“核心云”用于協(xié)調(diào)各“邊緣云”之間的存儲、計(jì)算資源的調(diào)度,在繼承了分布式云架構(gòu)的基礎(chǔ)上,解決了分布式云架構(gòu)存在的一些缺陷。針對邊緣云架構(gòu)的特點(diǎn),分析其與星型拓?fù)浣Y(jié)構(gòu)的契合性,提出了星型拓?fù)浣Y(jié)構(gòu)下的邊緣云架構(gòu)。通過分析其網(wǎng)絡(luò)延遲模型,提出了一套鏈路選擇方案為用戶選擇更快的連接鏈路,提升用戶體驗(yàn)。針對“邊緣云”分布式架構(gòu)導(dǎo)致的協(xié)作安全維持難度大的問題,根據(jù)適用環(huán)境和邊緣云架構(gòu)的特點(diǎn),提出了一套秘鑰分配方案增加系統(tǒng)安全性。使用Canopy+K-means聚類對數(shù)據(jù)進(jìn)行進(jìn)行聚類管理。針對在Canopy算法存在的閾值T1和T2的選擇問題上,分析動(dòng)環(huán)監(jiān)控系統(tǒng)的數(shù)據(jù)分布特色,提出了一套基于概率分布的計(jì)算方法進(jìn)行優(yōu)化。實(shí)驗(yàn)結(jié)果表明,本文方法能夠在確保傳統(tǒng)動(dòng)環(huán)監(jiān)控系統(tǒng)的基本功能的前提下,實(shí)現(xiàn)數(shù)據(jù)交互和協(xié)助計(jì)算,并能提供OMC異地操作的能力。同時(shí)在系統(tǒng)消耗和擴(kuò)展性方面,相對于分布式云有較好的表現(xiàn)。
[Abstract]:The moving-ring monitoring system is the guarantee of the stable operation of the computer room. Cloud computing is currently used in mobile-ring monitoring systems to manage and monitor large-area distributed computer rooms. With the rapid development of society, more and more manufacturers begin to set up their own computer rooms. However, with the number of server nodes expanding, the consumption of cloud service system increases exponentially, which limits the expansion ability of distributed cloud architecture. In order to enhance the expansibility of the system, the edge cloud architecture is applied to the moving ring monitoring system. Edge cloud architecture is to add a "core cloud" to coordinate the storage between the "edge clouds" and calculate the scheduling of resources on the basis of the distributed cloud architecture, which inherits the distributed cloud architecture. Some defects of distributed cloud architecture are solved. According to the characteristics of edge cloud architecture, the consistency between edge cloud architecture and star topology is analyzed, and the edge cloud architecture under star topology is proposed. By analyzing the network delay model, a link selection scheme is proposed to select a faster link for the user to improve the user experience. Aiming at the difficulty of cooperative security maintenance caused by the "edge cloud" distributed architecture, a secret key allocation scheme is proposed to increase the security of the system according to the characteristics of the applicable environment and the edge cloud architecture. Canopy K-means clustering is used to manage data clustering. Aiming at the problem of selecting threshold T 1 and T 2 in Canopy algorithm, the characteristics of data distribution in moving ring monitoring system are analyzed, and a set of calculation method based on probability distribution is proposed to optimize it. The experimental results show that the proposed method can realize data exchange and assist calculation on the premise of ensuring the basic functions of the traditional moving-ring monitoring system, and can provide the ability of OMC remote operation. At the same time, the system consumption and scalability, compared with the distributed cloud has a better performance.
