【摘要】：本文的工作基于下一代互聯(lián)網(wǎng),依托國家973項目“智慧協(xié)同網(wǎng)絡(luò)體系基礎(chǔ)研究”中有關(guān)智慧服務(wù)適配的基本思想,主要對如何在服務(wù)層上進行服務(wù)的標識與描述,并實現(xiàn)服務(wù)的智慧查找與動態(tài)匹配等問題進行設(shè)計研究。服務(wù)層在對服務(wù)命名基礎(chǔ)上,又引入服務(wù)行為描述對服務(wù)進行進一步表述。 在國家973項目“一體化可信網(wǎng)絡(luò)與普適服務(wù)體系基礎(chǔ)研究”中,已經(jīng)在普適服務(wù)層上設(shè)計并實現(xiàn)了服務(wù)標識解析系統(tǒng),用來完成服務(wù)標識到接入標識的映射。該系統(tǒng)采用分布式哈希表的結(jié)構(gòu)對注冊服務(wù)信息進行管理與維護,運行穩(wěn)定并能夠達到預(yù)期目標,相較于傳統(tǒng)域名解析機制有以下幾點優(yōu)勢： 1、對服務(wù)的描述能力強。域名解析只完成了域名到IP地址的映射,服務(wù)標識解析系統(tǒng)可以存儲的服務(wù)信息包括服務(wù)標識、服務(wù)名字、服務(wù)類型、服務(wù)質(zhì)量等。這樣用戶可以直接通過系統(tǒng)得到更多的信息變化。 2、支持移動性。域名解析基于主機,用戶通過域名解析得到主機位置再獲取服務(wù)資源,服務(wù)標識解析系統(tǒng)以服務(wù)內(nèi)容為中心,即直接通過服務(wù)標識查找服務(wù)資源。 3、均衡負載。由于服務(wù)標識解析系統(tǒng)采用分布式哈希表結(jié)構(gòu),每臺服務(wù)器地位相同,能夠更好地平衡負載。 基于以上服務(wù)標識解析系統(tǒng)在結(jié)構(gòu)上及功能上的優(yōu)越性,本文工作即在此基礎(chǔ)上,根據(jù)智慧服務(wù)的設(shè)計思想,對原有的服務(wù)標識解析系統(tǒng)進行修改,添加服務(wù)行為描述信息,在用戶查詢服務(wù)信息中加入服務(wù)適配模塊,目的在于提高系統(tǒng)的智能性,最終設(shè)計并實現(xiàn)一種能夠利用服務(wù)行為描述對服務(wù)名字進行選擇適配的智慧服務(wù)解析系統(tǒng),完成服務(wù)名字到身份標識的轉(zhuǎn)換。同時在服務(wù)獲取的過程中在中間路由器進行服務(wù)緩存,實現(xiàn)服務(wù)就近獲取,以進一步提高系統(tǒng)的效率。 本文首先對下一代互聯(lián)網(wǎng)國內(nèi)外研究背景與現(xiàn)狀進行簡單說明。之后介紹了智慧協(xié)同網(wǎng)絡(luò)基本理論模型。針對服務(wù)層所需要實現(xiàn)的功能引出了內(nèi)容名字解析系統(tǒng),并簡單介紹一體化網(wǎng)絡(luò)中的服務(wù)標識解析系統(tǒng)設(shè)計目的以及系統(tǒng)實現(xiàn)功能,在此基礎(chǔ)上,根據(jù)智慧服務(wù)思想,引出智慧服務(wù)解析系統(tǒng),并對該系統(tǒng)的模塊設(shè)計進行了詳細介紹。最后,搭建實驗環(huán)境,對智慧服務(wù)解析系統(tǒng)進行了實驗驗證。
[Abstract]:The work of this paper is based on the next generation Internet, relying on the basic idea of intelligent service adaptation in the National 973 Project "the basic Research of Intelligent Cooperative Network system". It mainly describes how to identify and describe the service on the service layer. The intelligent search and dynamic matching of service are designed and studied. On the basis of naming the service, the service layer introduces service behavior description to further describe the service. In the National 973 Project "Integrated trusted Network and the basic Research of pervasive Service system", a service identification parsing system has been designed and implemented on the universal service layer, which is used to map the service identification to the access identification. The system uses the structure of distributed hash table to manage and maintain the registration service information, which runs stably and can achieve the expected goal. Compared with the traditional domain name resolution mechanism, it has the following advantages: 1. Domain name resolution only maps domain name to IP address. The service information that can be stored by service identification resolution system includes service identification, service name, service type, service quality and so on. So that users can directly through the system to get more information changes. 2, support mobility. Domain name resolution is based on the host, the user obtains the location of the host through domain name resolution to obtain the service resources, and the service identity resolution system takes the service content as the center, that is to find the service resources directly through the service identification. 3, balancing the load. Because the service identity resolution system adopts the distributed hash table structure, each server has the same status and can balance the load better. Based on the advantages of the above service identification analysis system in structure and function, this paper is based on the design idea of intelligent service, the original service identification analysis system is modified, and service behavior description information is added. In order to improve the intelligence of the system, the service adaptation module is added to the user query service information. Finally, a intelligent service parsing system is designed and implemented, which can select and adapt the service name by using the service behavior description. Complete the service name to identity conversion. At the same time, in the process of service acquisition, the service cache is carried out in the intermediate router to achieve service acquisition in order to further improve the efficiency of the system. In this paper, the background and current situation of next-generation internet research at home and abroad are briefly explained. Then the basic theoretical model of intelligent cooperative network is introduced. According to the function of service layer, this paper introduces the content name parsing system, and introduces the design purpose and system realization function of the service identification and resolution system in the integrated network. On this basis, according to the intelligent service idea, the paper introduces the design purpose of the service identification and analysis system and the function of the system. The intelligent service analysis system is introduced, and the module design of the system is introduced in detail. Finally, the experiment environment is built to verify the intelligent service analysis system.
