【摘要】：互聯(lián)網(wǎng)已成為當(dāng)前信息社會(huì)不可缺少的重要組成部分,隨著互聯(lián)網(wǎng)幾十年的發(fā)展,其接入方式和網(wǎng)絡(luò)功能定位發(fā)生了巨大的改變。TCP/IP體系結(jié)構(gòu)在可擴(kuò)展性、動(dòng)態(tài)性以及安全可控性等方面的問(wèn)題日漸突顯,已經(jīng)無(wú)法滿足互聯(lián)網(wǎng)持續(xù)發(fā)展的需求,基于此國(guó)內(nèi)外研究者開(kāi)展了未來(lái)網(wǎng)絡(luò)體系結(jié)構(gòu)的研究。 本文在面向服務(wù)的未來(lái)互聯(lián)網(wǎng)體系結(jié)構(gòu)(SOFIA)的架構(gòu)背景下,研究了未來(lái)互聯(lián)網(wǎng)中面向內(nèi)容和服務(wù)的命名標(biāo)識(shí)機(jī)制、尋址與解析體系。首先調(diào)研了下一代互聯(lián)網(wǎng)的研究現(xiàn)狀,并針對(duì)命名與解析問(wèn)題進(jìn)行了較為深入的研究,互聯(lián)網(wǎng)用戶更關(guān)注網(wǎng)絡(luò)中可以提供的內(nèi)容和服務(wù)比如信息搜索、內(nèi)容分享、云計(jì)算等等,而不是他們的位置信息。在未來(lái)互聯(lián)網(wǎng)體系的“革命式”架構(gòu)中,內(nèi)容和服務(wù)將取代主機(jī)成為網(wǎng)絡(luò)中命名的“實(shí)體”,詳細(xì)調(diào)研了面向內(nèi)容和服務(wù)的命名方法和解析機(jī)制,并總結(jié)分析了命名解析機(jī)制中的基本問(wèn)題和基本思想,然后從對(duì)各種基于內(nèi)容和服務(wù)的命名方法研究出發(fā),借鑒并提出了適用于描述服務(wù)的靈活命名機(jī)制,并研究了適用于此命名機(jī)制的高效的解析查詢系統(tǒng)。 本文構(gòu)建了分布式P2P網(wǎng)絡(luò)作為解析系統(tǒng),采用Chord算法做為底層路由算法,并提出了一種新的基于DHT的多屬性查詢算法,該算法適用于本文中的層次化屬性-值對(duì)描述的服務(wù)標(biāo)識(shí),使得解析系統(tǒng)在查詢效率和負(fù)載均衡方面有了更好的平衡。經(jīng)過(guò)仿真驗(yàn)證,該算法減少了服務(wù)名字的副本存儲(chǔ)量,并且有更好的負(fù)載均衡性和查詢性能。
[Abstract]:The Internet has become an indispensable part of the current information society. With the development of the Internet for decades, its access mode and network function orientation have changed greatly. TCPP / IP architecture is extensible.The problems of dynamic and security controllability are becoming more and more prominent, which can not meet the needs of the sustainable development of the Internet. Based on this, researchers at home and abroad have carried out research on the future network architecture.In this paper, based on the architecture of Service-Oriented Future Internet Architecture (SOFIA), we study the naming and identification mechanism, addressing and parsing architecture of content-oriented and service-oriented Internet in the future.First of all, the research status of next generation Internet is investigated, and the naming and parsing problem is deeply studied. Internet users pay more attention to the content and services that can be provided in the network, such as information search, content sharing, cloud computing and so on.Not their location.In the "revolutionary" architecture of the future Internet system, content and services will replace hosts as named "entities" in the network. The naming methods and parsing mechanisms for content and services are investigated in detail.The basic problems and basic ideas of naming parsing mechanism are summarized and analyzed. Then, based on the research of various naming methods based on content and service, a flexible naming mechanism suitable for describing services is put forward.An efficient parse query system suitable for this naming mechanism is also studied.In this paper, a distributed P2P network is constructed as an analytical system, and Chord algorithm is used as the underlying routing algorithm, and a new multi-attribute query algorithm based on DHT is proposed.This algorithm is suitable for the service identification described by the hierarchical attribute-value pairs in this paper, which makes the parsing system have a better balance between query efficiency and load balance.The simulation results show that the algorithm reduces the storage of service names and has better load balancing and query performance.
