【摘要】：隨著網絡技術的不斷發(fā)展，越來越多的人通過網絡來了解信息，由于用戶群體的不斷增加及網絡應用的豐富，使得服務器接收到的請求數(shù)越來越多，，有關于網絡負載的問題越發(fā)突出。集群技術的出現(xiàn)很好地解決了這一問題。本文主要貢獻及創(chuàng)新點包括： 1、提出了一種基于Agent的動態(tài)自適應集群負載均衡模型。通過把Agent技術引入集群負載均衡系統(tǒng)中，創(chuàng)新性的構建了一個基于Agent的動態(tài)自適應集群負載均衡的普適模型。將Agent技術引入到傳統(tǒng)集群負載均衡模型中，增加了集群負載系統(tǒng)的智能性和自適應能力； 2、創(chuàng)新性的把請求任務識別與分類思想融合到了基于Agent的集群動態(tài)負載均衡模型中。通過引入請求任務識別與分類思想，結合Agent技術，實現(xiàn)了集群任務的自動識別及分類處理，提高了集群系統(tǒng)的運行效率； 3、針對本文提出的基于Agent的集群動態(tài)負載均衡模型，對其具體功能設計了詳細的算法，并針對模型多個指標做了性能分析。 4、提出并實現(xiàn)了一種適用于流媒體業(yè)務的基于Agent的動態(tài)自適應負載均衡集群。在詳細分析了流媒體業(yè)務存在的問題及特點的基礎上，根據(jù)這些問題及特點做了針對性的優(yōu)化，設計了針對于流媒體業(yè)務的集群模型并給出了具體實現(xiàn)。實驗結果驗證了本文模型的普適性和有效性。 5、提出并實現(xiàn)了一種針對移動互聯(lián)網業(yè)務的基于Agent的動態(tài)自適應負載均衡集群。針對移動互聯(lián)網特點及新的挑戰(zhàn)，設計了一種針對移動互聯(lián)網的基于Agent的負載均衡集群，此集群結合本文提出的模型進行設計，同時又兼顧了移動互聯(lián)網的特點。進一步驗證了本文模型的普適性和有效性的同時。
[Abstract]:With the continuous development of network technology, more and more people understand information through the network. Due to the increasing number of users and the rich application of network, more and more requests are received by the server. There is a growing problem with network load. The emergence of cluster technology solves this problem well. The main contributions and innovations of this paper are as follows: 1. A dynamic adaptive cluster load balancing model based on Agent is proposed. By introducing Agent technology into cluster load balancing system, an innovative universal model of dynamic adaptive cluster load balancing based on Agent is constructed. The Agent technology is introduced into the traditional cluster load balancing model, which increases the intelligence and adaptive ability of the cluster load system. 2. The idea of request task identification and classification is innovatively integrated into the cluster dynamic load balancing model based on Agent. By introducing the idea of request task identification and classification and combining with Agent technology, the automatic recognition and classification of cluster tasks are realized, and the running efficiency of cluster system is improved. 3. Aiming at the cluster dynamic load balancing model based on Agent proposed in this paper, a detailed algorithm is designed for its specific function, and the performance analysis is made for several indexes of the model. 4. A dynamic adaptive load balancing cluster based on Agent for streaming media services is proposed and implemented. On the basis of analyzing the problems and characteristics of streaming media service in detail, the paper optimizes these problems and characteristics, designs the cluster model for streaming media service and gives the concrete implementation. The experimental results verify the universality and validity of the model. 5. A dynamic adaptive load balancing cluster based on Agent for mobile Internet services is proposed and implemented. Aiming at the characteristics and new challenges of mobile Internet, a load balancing cluster based on Agent for mobile Internet is designed. The cluster is designed in combination with the model proposed in this paper, and at the same time, the characteristics of mobile Internet are taken into account. Furthermore, the generality and validity of the model are verified at the same time.
