【摘要】：P2P(Peer to Peer)技术已成为互联网革新的关键技术之一,近些年来已应用于互联网行业的各个领域。P2P技术改变了人们的沟通交流方式,让人们通过互联网直接进行高效沟通交流。现今,P2P网络结构或其中的算法已开始应用于流媒体视频点播软件、非关系数据库、云平台底层结构,并得到很好反响。 P2P模型研究的关键在于P2P技术。目前大多数P2P应用都是基于经典模型,但经典模型算法本身是有适用范围的,并不能满足某些P2P应用运行条件,因此我们要探索开发新的网络模型。 本文首先总结并分析了当前对等网络经典模型,并在混合式对等网络模型KaZaA基础上提出一个高效路由、负载均衡、可扩展的、动态的对等网络分层路由模型LRHN(Location Relevant Hierarchy Hybrid P2P Network)。基于为用户提供用户的准确定位、用户的组群管理和文件资源传输等基本的信息服务的目标,本文对LRHN网络模型进行了详细设计,包括模型的分层架构和组网路由机制等。本文重点地描述了LRHN模型两层架构及运作机制,其中对超级节点和普通节点的基本路由和维护算法做了详细地阐述。最后,通过仿真试验对LRHN模型的合理性和路由效率进行了验证和测试,基本上达到了预期的设计目的。
[Abstract]:P2P (Peer to Peer) technology has become one of the key technologies of Internet innovation, which has been applied in various fields of the Internet industry in recent years. P2P technology has changed the way people communicate and communicate directly and efficiently through the Internet. Nowadays, P2P network structure or its algorithms have been applied to streaming media video-on-demand software, non-relational database, cloud platform bottom structure, and get a good response. The key to the research of P2P model lies in P2P technology. At present, most P2P applications are based on classical models, but the classical model algorithms have their own scope of application and can not meet the running conditions of some P2P applications, so we should explore and develop new network models. This paper first summarizes and analyzes the current classical peer-to-peer network model, and proposes an efficient routing, load balancing, extensible, dynamic peer-to-peer network hierarchical routing model LRHN (Location Relevant Hierarchy Hybrid P2P Network). Based on the hybrid peer-to-peer network model KaZaA. Based on the objectives of providing users with accurate location, group management and file resource transmission, the LRHN network model is designed in detail, including the hierarchical architecture of the model and the routing mechanism of the group network. This paper focuses on the two-tier architecture and operation mechanism of LRHN model, in which the basic routing and maintenance algorithms of super nodes and ordinary nodes are described in detail. Finally, the rationality and routing efficiency of LRHN model are verified and tested by simulation experiments, and the expected design purpose is basically achieved.
