可管可控P2P覆盖网管理方法研究
|
摘要
互联网在过去的十年中得到迅速的发展和普及,已经成为人们日常生活和工作中不可或缺的信息承载工具。P2P技术具有去中心化、可扩展性强、健壮性、负载均衡等优势,极大地促进了互联网业务的发展和应用类型的丰富,也加快了P2P技术的发展。P2P技术及应用的迅速发展对传统的电信业务及运营管理造成了巨大的挑战,对P2P网络进行有效的管控成为亟待解决的问题。本文围绕P2P覆盖网的管控问题,探讨有效的P2P覆盖网构建方案,并通过构建的可管可控P2P覆盖网对覆盖网的网络、资源、节点进行有效的管理。
本文首先分析了国内外可管可控P2P网络的研究现状及P2PSIP为了规范P2P网络提出的RELOAD协议。针对P2P覆盖网“无政府状态”引起的网络无管控问题,提出了一种可管可控P2P覆盖网架构对P2P覆盖网中网络、资源和节点进行管理。
为了解决非结构化P2P随着网络规模增大而增加的查找代价、扩展性不好及结构化P2P不支持资源的复杂查询方式的问题,提出了一种层次化的P2P覆盖网,由运营商预先部署的服务节点或网络中选举出的高能力节点作为网络中的负责节点构成上层覆盖网。在P2P覆盖网中,由业务覆盖网对P2P业务进行管理,由资源覆盖网对网络中的资源进行管理。基于可管可控P2P覆盖网架构及分层的P2P网络结构,明确了P2P覆盖网网络、资源及节点的管控方式,包括分层覆盖网的构建及维护方法,资源存储、发布、定位、删除与管理方式,访问负载均衡方法,节点认证管理及节点选取方式等。最后通过理论验证说明所构建的覆盖网的性能优势,包括资源定位效率与网络维护代价等,并通过仿真对其优势进行论证说明。
本文首先对P2P覆盖网及其相关技术进行了综述,并介绍了可管可控P2P覆盖网架构的设计。接着阐述了本文提出的针对网络、资源、节点的P2P覆盖网管理方法,对可管可控P2P覆盖网的管理性能进行理论分析和仿真分析。最后对本文的工作进行了总结和展望。
In the past decade, internet has been rapidly developed andpopularized and has become an indispensable tool in each person's daily life and work. The features and advantages of P2P technology promote the development of Internet services and enrich the application types, and in the same time, speed up the development of itself.
However, the rapid development of P2P technology and applications brings huge challenges to the traditional telecommunications services andoperation management.It becomes anurgent problem to control the P2P networks in effective ways. To address this problem, this thesis aims to explore effective P2P overlay construction schemes to manage the overlay's networks, resources and nodes.
In this thesis, the authoranalyzed the research status of the manageable and controllable P2P networks and the RELOAD protocol proposed by P2PSIP. To solve the problems caused by "anarchy" of the P2P overlay, the author put forward amanageable and controllable P2P overlay architecture to manage the networks, resources and peers in the overlay.
To solve the high-costs for searching and poor scalabilitywhich is caused by the increasing network size in unstructured P2P network and the problem that does not support complex queries in structured P2P network, this thesis put forward a hierarchical P2Pnetwork. The service nodes which are pre-deployed by ISP and the nodes which are selected by network are acted as the responsible node in the upper overlay.The service overlay is responsible for managing P2P service and the resource overlay is responsible for managing P2P resourcein the network. In addition, with the construct P2P overlay network and the hierarchical P2P overlay network, this thesis make clear how to control the overlay network, resource and nodes. Including the construction and maintenance methods of the hierarchical overlay network, the management of resource store, release,locate and delete, load balancing method for accessing, and the authenticate and management of nodes. At last, theory verification instructions will be given to explain the performance of the overlay, the theory verification including the resource location efficient and the cost of network maintenance, in addition, use the simulation to demonstrate the overlay's advantages.
This thesis firstly introduces the related technologies of P2P overlay, while describes the design of manageable and controllable P2P overlay architecture. Secondly, this thesis describes the management methods of the network, resources, and node in the P2P network. Then it makes theoretical analysis and simulation verification of the P2P overlay management performance. Finally, work summary and outlook are given by this thesis.
