【摘要】：互联网已成为当前信息社会不可缺少的重要组成部分,随着互联网几十年的发展,其接入方式和网络功能定位发生了巨大的改变。TCP/IP体系结构在可扩展性、动态性以及安全可控性等方面的问题日渐突显,已经无法满足互联网持续发展的需求,基于此国内外研究者开展了未来网络体系结构的研究。本文在面向服务的未来互联网体系结构(SOFIA)的架构背景下,研究了未来互联网中面向内容和服务的命名标识机制、寻址与解析体系。首先调研了下一代互联网的研究现状,并针对命名与解析问题进行了较为深入的研究,互联网用户更关注网络中可以提供的内容和服务比如信息搜索、内容分享、云计算等等,而不是他们的位置信息。在未来互联网体系的“革命式”架构中,内容和服务将取代主机成为网络中命名的“实体”,详细调研了面向内容和服务的命名方法和解析机制,并总结分析了命名解析机制中的基本问题和基本思想,然后从对各种基于内容和服务的命名方法研究出发,借鉴并提出了适用于描述服务的灵活命名机制,并研究了适用于此命名机制的高效的解析查询系统。本文构建了分布式P2P网络作为解析系统,采用Chord算法做为底层路由算法,并提出了一种新的基于DHT的多属性查询算法,该算法适用于本文中的层次化属性-值对描述的服务标识,使得解析系统在查询效率和负载均衡方面有了更好的平衡。经过仿真验证,该算法减少了服务名字的副本存储量,并且有更好的负载均衡性和查询性能。
[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.
