A Hierarchical Namespace And Resolution System Based On Content And Service

Internet has become an important and indispensable component of the current information society, with the development of Internet for decades; Great changes have taken place in its means of access and network function. TCP/IP architecture has increasingly highlighted its problems in terms of scalability, dynamic and security controllability, cannot meet the needs of sustainable development of the Internet. Based on this, domestic and foreign researchers conducted the study of future network architecture.This paper study the content and service oriented naming mechanism, addressing and resolution system of the future Internet in the background of Service-Oriented Future Internet Architecture (SOFIA),First investigated the current research status quo of the next generation Internet, and in-depth studied the naming and resolution issues. Internet users focus on the content and service which network can provide such as information searching, content sharing, cloud computing, etc., rather than their location. In the "clean-slate" future Internet architecture, content and service will replace the host as the naming entity in the network. This paper researched the content and service oriented naming and resolution mechanism in detail, and analyzed the basic issues and idea of the naming and resolution mechanism, then referred to the research on various naming method based on the content and service, proposed a flexible naming scheme applicable to describe the service, and researched the resolution system suitable for this naming mechanism.In this paper, we build a distributed P2P network as the resolution system, using Chord algorithm as the underlying routing algorithm, and proposes a new multi-attribute query algorithm based on DHT, the algorithm is suitable for the hierarchical attributes-value identification of service described in this paper, made a better balance between query efficiency and load balancing. Through simulation, the algorithm reduces the copy amount of the service name, and has better load balancing and query performance.
