【摘要】：現(xiàn)代科學(xué)技術(shù)和生產(chǎn)力已經(jīng)越來越多地依賴于信息網(wǎng)絡(luò)技術(shù),從而催生了信息網(wǎng)絡(luò)技術(shù)的迅速發(fā)展,并使其成為各個(gè)國家和地區(qū)競爭的焦點(diǎn)�，F(xiàn)有的信息網(wǎng)絡(luò)如電話網(wǎng)、廣播電視網(wǎng)等都是一種網(wǎng)絡(luò)基本只支撐一種服務(wù),為了提供不同種類的服務(wù),只能通過重復(fù)建設(shè)多種網(wǎng)絡(luò)的方式實(shí)現(xiàn),從而造成了巨大的資源浪費(fèi),也導(dǎo)致了網(wǎng)絡(luò)升級換代和管理維護(hù)困難等問題,形成惡性循環(huán)。為此,必須研究和探索一種全新的網(wǎng)絡(luò)體系,從根本上解決當(dāng)前信息網(wǎng)絡(luò)存在的上述嚴(yán)重缺陷。在此背景下,一體化網(wǎng)絡(luò)提出了一個(gè)全新的分為兩層的結(jié)構(gòu)模型,可以有效地解決現(xiàn)有信息網(wǎng)絡(luò)的結(jié)構(gòu)性缺陷。 本論文對當(dāng)前一體化網(wǎng)絡(luò)中的服務(wù)注冊機(jī)制進(jìn)行了分析,針對現(xiàn)有注冊機(jī)制存在的問題進(jìn)行了研究,提出了一種基于標(biāo)簽的服務(wù)主動注冊模型,該模型可以有效地解決現(xiàn)有服務(wù)注冊機(jī)制存在的服務(wù)類型單一、服務(wù)描述不夠詳細(xì)等問題�；�于該模型,本論文設(shè)計(jì)和實(shí)現(xiàn)了基于標(biāo)簽的服務(wù)主動注冊系統(tǒng)。系統(tǒng)功能包括服務(wù)原始數(shù)據(jù)的獲取和分析,不同類型服務(wù)標(biāo)簽的定義和提取,統(tǒng)一的服務(wù)標(biāo)識的生成,服務(wù)注冊報(bào)文格式的定義,服務(wù)信息數(shù)據(jù)庫中不同服務(wù)類型的服務(wù)信息表的定義,服務(wù)信息的注冊等。該系統(tǒng)通過在網(wǎng)絡(luò)中部署服務(wù)數(shù)據(jù)捕獲模塊,捕獲服務(wù)的原始數(shù)據(jù)包,對其進(jìn)行分流和重組,從而獲得服務(wù)的應(yīng)用層數(shù)據(jù)；接著根據(jù)不同的服務(wù)類型,調(diào)用不同的服務(wù)標(biāo)簽提取模塊對應(yīng)用層數(shù)據(jù)進(jìn)行分析并提取出服務(wù)標(biāo)簽,寫入設(shè)計(jì)好的標(biāo)簽數(shù)據(jù)結(jié)構(gòu),再根據(jù)服務(wù)標(biāo)識生成策略生成服務(wù)標(biāo)識；最后將服務(wù)信息發(fā)送到服務(wù)注冊模塊,由服務(wù)注冊模塊將服務(wù)信息注冊到服務(wù)信息數(shù)據(jù)庫中。 本論文選擇了兩種典型的互聯(lián)網(wǎng)服務(wù)即SMTP郵件服務(wù)和FTP文件服務(wù)進(jìn)行了功能實(shí)現(xiàn),并對實(shí)現(xiàn)的功能進(jìn)行了測試。測試結(jié)果表明,本論文設(shè)計(jì)和實(shí)現(xiàn)的基于標(biāo)簽的服務(wù)主動注冊系統(tǒng)可以有效地實(shí)現(xiàn)原始服務(wù)數(shù)據(jù)的捕獲、服務(wù)標(biāo)簽信息的提取、統(tǒng)一服務(wù)標(biāo)識的生成以及服務(wù)信息的注冊和存儲等功能,驗(yàn)證了基于標(biāo)簽的服務(wù)主動注冊模型的正確性和有效性,為一體化網(wǎng)絡(luò)的服務(wù)注冊機(jī)制研究以及一體化網(wǎng)絡(luò)實(shí)際大規(guī)模部署做出了貢獻(xiàn)。
[Abstract]:Modern science and technology and productivity have become more and more dependent on information network technology, which has given birth to the rapid development of information network technology and made it become the focus of competition in various countries and regions. The existing information network, such as telephone network, radio and television network, is a kind of network that basically supports only one kind of service. In order to provide different kinds of services, it can only be realized by repeatedly building a variety of networks, resulting in a huge waste of resources. It also leads to network upgrading and management and maintenance difficulties, forming a vicious circle. Therefore, it is necessary to study and explore a new network system to fundamentally solve the above serious defects of the current information network. In this context, the integrated network proposes a new two-layer structure model, which can effectively solve the structural defects of the existing information network. In this paper, the service registration mechanism in the current integrated network is analyzed, the existing problems of the existing registration mechanism are studied, and a label-based active service registration model is proposed. The model can effectively solve the problems of single service type and insufficient service description existing in the existing service registration mechanism. Based on this model, this paper designs and implements an active service registration system based on label. The functions of the system include the acquisition and analysis of service raw data, the definition and extraction of different types of service tags, the generation of unified service identity, and the definition of service registration message format. The definition of service information table of different service types and the registration of service information in service information database. By deploying the service data capture module in the network, the system captures the original data packets of the service, splits and reorganizes it, so as to obtain the application layer data of the service. Then, according to different service types, different service tag extraction modules are called to analyze the application layer data and extract the service label, write the designed label data structure, and then generate the service identity according to the service identity generation strategy. Finally, the service information is sent to the service registration module, and the service information is registered into the service information database by the service registration module. In this paper, two typical Internet services, SMTP mail service and FTP file service, are selected to realize the function, and the function of the implementation is tested. The test results show that the label-based active service registration system designed and implemented in this paper can effectively capture the original service data and extract the service label information. The generation of unified service identity and the registration and storage of service information verify the correctness and effectiveness of the label-based active service registration model. It contributes to the research of service registration mechanism of integrated network and the actual large-scale deployment of integrated network.
