Research On Management Methods Of Manageable And Controllable P2P Overlay Network

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.
