【摘要】：隨著信息互聯(lián)技術(shù)的飛速發(fā)展,互聯(lián)網(wǎng)的規(guī)模正在穩(wěn)健地?cái)U(kuò)大,給人們帶來更多便捷的同時(shí),也因其原始設(shè)計(jì)的缺陷帶來了各式各樣的弊端,出現(xiàn)了可擴(kuò)展性差,安全性差,移動(dòng)性差等種種問題。為了解決傳統(tǒng)互聯(lián)網(wǎng)存在的這些問題,國內(nèi)外眾多機(jī)構(gòu)都致力于下一代互聯(lián)網(wǎng)的研究,其中一種主流思想就是將身份與位置分離開來。北京交通大學(xué)下一代互聯(lián)網(wǎng)互聯(lián)設(shè)備國家工程實(shí)驗(yàn)室提出了一體化標(biāo)識(shí)網(wǎng)絡(luò)的概念,采用身份與位置分離的思想將終端的身份信息和位置信息隔離開來,用接入標(biāo)識(shí)表示終端的身份信息,用路由標(biāo)識(shí)表示終端的位置信息,通過映射系統(tǒng)來實(shí)現(xiàn)相關(guān)信息的存儲(chǔ)和查詢功能。本文基于一體化標(biāo)識(shí)網(wǎng)絡(luò),根據(jù)現(xiàn)有映射系統(tǒng)的映射緩存信息一致性較弱等缺點(diǎn),對現(xiàn)有的分布式映射系統(tǒng)進(jìn)行改進(jìn)設(shè)計(jì),通過設(shè)計(jì)進(jìn)程間通信完善映射信息的發(fā)布和恢復(fù)過程后,在此一體化標(biāo)識(shí)網(wǎng)絡(luò)下,用映射服務(wù)器來對接入交換路由器中遠(yuǎn)端映射緩存表中緩存的映射關(guān)系進(jìn)行控制,設(shè)計(jì)一種保證映射緩存強(qiáng)一致性的機(jī)制。本文首先對身份與位置分離網(wǎng)絡(luò)的映射系統(tǒng)的背景進(jìn)行討論,然后對一體化標(biāo)識(shí)網(wǎng)絡(luò)的架構(gòu)原理,工作實(shí)體以及通信流程進(jìn)行詳細(xì)的講解。在完善一體化標(biāo)識(shí)網(wǎng)絡(luò)中歸屬域信息發(fā)布和恢復(fù)的前提下,針對映射信息查詢過程中的緩存一致性信息查詢,設(shè)計(jì)具體的工作流程和解析機(jī)制,對緩存查詢解析模塊和緩存處理模塊這兩個(gè)一致性模塊進(jìn)行設(shè)計(jì),并在代碼上進(jìn)行了實(shí)現(xiàn),同時(shí)對各個(gè)功能模塊進(jìn)行功能性測試,驗(yàn)證了歸屬域信息的自動(dòng)發(fā)布和恢復(fù),以及緩存的時(shí)效性,并對緩存的弱一致性和強(qiáng)一致性進(jìn)行了性能的對比,提出了強(qiáng)一致性的必要性。最后對全文工作進(jìn)行了分析與總結(jié),并對后續(xù)的工作進(jìn)行了展望。
[Abstract]:With the rapid development of information interconnection technology, the scale of the Internet is expanding steadily, which brings more convenience to people. At the same time, because of the defects of its original design, it also brings all kinds of drawbacks, resulting in poor scalability and poor security. Poor mobility and other problems. In order to solve these problems of traditional Internet, many institutions at home and abroad are committed to the next generation of Internet research, one of the mainstream ideas is to separate identity from location. The National Engineering Laboratory of next Generation Internet Interconnection equipment of Beijing Jiaotong University has put forward the concept of integrated identification network, which uses the idea of separating identity and location to separate the identity information and location information of the terminal. The identity information of the terminal is represented by the access identification, the location information of the terminal is represented by the route identification, and the function of storing and querying the relevant information is realized by the mapping system. Based on the integrated identification network and the weak consistency of the mapping cache information of the existing mapping system, this paper improves the design of the existing distributed mapping system. After designing inter-process communication to improve the release and recovery of mapping information, the mapping server is used to control the mapping relationship of the remote mapping cache table in the access switch router under the integrated identification network. A mechanism to ensure strong consistency of mapping cache is designed. In this paper, the background of the mapping system of identity and location separation network is discussed, and then the architecture principle, working entity and communication flow of integrated identification network are explained in detail. On the premise of perfecting the distribution and recovery of home domain information in the integrated identification network, the concrete workflow and parsing mechanism are designed for the cache consistency information query in the process of mapping information query. The cache query parsing module and cache processing module are designed and implemented in code. At the same time, the functional test of each functional module is carried out to verify the automatic release and recovery of home domain information. The paper also compares the performance of cache with weak consistency and strong consistency, and puts forward the necessity of strong consistency. Finally, the paper analyzes and summarizes the work, and the future work is prospected.
