【摘要】:截止目前企業(yè)面向的零售戶量已經(jīng)突破900萬,隨著信息化和數(shù)據(jù)化的加深,采集零售戶數(shù)據(jù)和信息也是勢在必行的。面對900萬的用戶量,隨之引起問題的是服務器的訪問量急劇上升,數(shù)據(jù)量呈爆炸式增長。以企業(yè)目前的服務器等硬件設備已經(jīng)無法滿足高并發(fā)、大數(shù)據(jù)的需求。如果只是增加多臺服務器組成服務器集群,提高硬件、軟件的性能,來解決大量用戶并發(fā)請求和大數(shù)據(jù)處理的問題,這顯然并不是很好的辦法。本文通過分析和對比傳統(tǒng)的數(shù)據(jù)采集模式和企業(yè)業(yè)務類型,設計了一種基于移動端的數(shù)據(jù)采集模式。并詳細的分析了該數(shù)據(jù)采集模型,為了滿足企業(yè)的要求和用戶的需求,針對新型采集模式面對的高并發(fā)、大數(shù)據(jù)處理的問題,進一步分析和研究了負載均衡調(diào)度策略,并根據(jù)基于高并發(fā)的特征和調(diào)度算法的特點,在多時間片輪詢調(diào)度機制的基礎上提出了基于任務請求預測的動態(tài)調(diào)整負載均衡算法。并通過分析多維Markov鏈和排隊論對算法進行進一步的調(diào)整和改進,經(jīng)過實驗驗證,該算法較好地提高了整體系統(tǒng)的性能和負載。具體研究內(nèi)容如下:1)本文通過對比傳統(tǒng)數(shù)據(jù)采集方法,根據(jù)目前企業(yè)的業(yè)務類型和數(shù)據(jù)請求特征,設計了一種基于分布式策略的新型數(shù)據(jù)采集模型,該模型將APP和微信企業(yè)號作為數(shù)據(jù)采集的入口,并且組建服務器集群對高并發(fā)業(yè)務進行調(diào)度處理。使用基于Hadoop平臺的策略創(chuàng)建了數(shù)據(jù)中心,并對數(shù)據(jù)進行了分析和處理。其中對全國零售戶請求的業(yè)務類型和提交的數(shù)據(jù)性質,對該模型進行了初步優(yōu)化處理。并通過分析模型系統(tǒng)中的層次結構和技術要點,提出了在高并發(fā)環(huán)境下,如何高效地調(diào)度任務請求和調(diào)整服務器節(jié)點的負載的問題,并在后文進行了分析和解決。2)深入研究了基于CPU和MEM的調(diào)度算法,根據(jù)實際任務請求的特征,改進并提出了基于預測機制的負載均衡調(diào)度算法。各個服務器節(jié)點會收集其它節(jié)點的負載情況,并預測網(wǎng)絡請求的業(yè)務類型和到達率,動態(tài)的調(diào)整請求的分發(fā),減少請求的等待時間,并縮短服務器的閑置時間,達到資源的有效利用,最終使系統(tǒng)的整體負載達到均衡狀態(tài)。通過實驗驗證,該算法在縮短響應時間方面具有良好的性能,并且比基于CPU和MEM的調(diào)度算法性能更好。3)針對基于預測機制的負載均衡算法本身存在的不足,利用排隊論的知識,對網(wǎng)絡服務器方面的負載進行了優(yōu)化,合理的安排任務請求的等待、處理和掛起。通過分析多維Markov的機制,對后續(xù)網(wǎng)絡請求的特征和聯(lián)系進行預測。通過分析多時間片輪詢策略,提出了基于預測的Markov排隊模型。經(jīng)過實驗的驗證和分析,該模型較好的協(xié)調(diào)各服務器節(jié)點的負載狀況,合理的分發(fā)后續(xù)到達的網(wǎng)絡請求,減小響應時間。4)根據(jù)數(shù)據(jù)采集模型和負載均衡技術,建立了一套集移動終端數(shù)據(jù)采集平臺、業(yè)務處理平臺、數(shù)據(jù)處理平臺的三位一體的數(shù)據(jù)采集系統(tǒng)。并將負載均衡技術應用到數(shù)據(jù)處理中,加快了服務器處理數(shù)據(jù)的時間,并展示了數(shù)據(jù)采集系統(tǒng)設計實現(xiàn)的成果。
[Abstract]:Up to now, the number of retail customers facing the enterprise has exceeded 9 million. With the deepening of information and data, it is imperative to collect data and information of retail customers. Facing 9 million users, the problem is that the amount of access to the server is rising rapidly and the amount of data is exploding. It is obviously not a good way to solve the problem of a large number of concurrent requests and large data processing, which is obviously not a very good solution. This article analyzes and compares the traditional data collection mode and enterprise business by analyzing and comparing the problems of large number of concurrent requests and large data processing. Type, a data acquisition model based on mobile terminal is designed, and the data acquisition model is analyzed in detail. In order to meet the requirements of the enterprise and the needs of the users, the load balancing scheduling strategy is further analyzed and studied for the problems of high concurrency and large data processing in the new collection mode. On the basis of the multi time chip polling scheduling mechanism, the dynamic adjustment load balancing algorithm based on the task request prediction is proposed. The algorithm is further adjusted and improved by analyzing the multidimensional Markov chain and queuing theory. The algorithm improves the performance and negative effect of the whole system. The specific research contents are as follows: 1) in this paper, a new data acquisition model based on the distributed strategy is designed by comparing the traditional data acquisition methods, according to the business types and data request features of the current enterprise. This model takes APP and WeChat enterprise number as the entrance of data collection, and sets up a server cluster for high concurrency services. The data center is created using the strategy based on the Hadoop platform, and the data are analyzed and processed. The model is optimized for the type of business and the nature of the data submitted by the national retail customers, and the high level structure and technical points in the model system are put forward. In the concurrent environment, how to efficiently schedule task requests and adjust the load of server nodes, and analyze and solve.2 in the later text, the scheduling algorithm based on CPU and MEM is deeply studied. According to the characteristics of the actual task request, the load balancing scheduling algorithm based on the prediction machine is improved and proposed. Collect the load of other nodes, predict the type of service and the rate of arrival of the network request, dynamically adjust the request distribution, reduce the waiting time of the request, shorten the idle time of the server, achieve the effective utilization of the resource, and finally make the whole load of the system reach the balance state. The inter aspect has good performance and is better than the scheduling algorithm based on CPU and MEM). In view of the shortcomings of the load balancing algorithm based on the prediction mechanism, using the knowledge of queuing theory, it optimizes the load of the network server and arranges the waiting, processing and hanging up. By analyzing multidimensional Ma. The mechanism of rkov predicts the characteristics and connections of the subsequent network requests. Through the analysis of the multi time slice polling strategy, a prediction based Markov queuing model is proposed. Through the experimental verification and analysis, the model is better to coordinate the load status of each server node, to distribute the following network requests reasonably, and to reduce the response time.4). According to the data collection model and the load balancing technology, a set of data collection system is set up, which sets the data collection platform of the mobile terminal, the business processing platform and the data processing platform. The load balancing technology is applied to the data processing, and the time for the server to deal with the data is speeded up, and the design of the data acquisition system is demonstrated. The present results.
