Problems solved by technology

In a P2P network, retrieved content needs to be distributed and stored in each peer node, but for a P2P network where nodes frequently join and exit, maintaining the P2P network will occupy most of the system resources of the peer node

Embodiment Construction

[0033] The development computer is "DELL microcomputer, Intel(R) Core(TM) 2Duo CPUE7400 3.00GHz, 2GB memory, 250G hard disk" among the present embodiment. The development environment of VisualStudio2008+SQLServer2005 is adopted, and the programming language is C#. The hardware includes servers and ordinary PCs, and the operating environment of the servers is Windows Server 2003+IIS6.0+.net framework2.0. The client is an ordinary PC, and the operating environment is an operating system of Windows XP or above +.net framework2.0. Directory retrieval is based on C / S mode and P2P mode, applied to Internet network environment, using TCP / IPv4 protocol.

[0034] The present invention operates on 3TNet (high-performance broadband information network), deploys two retrieval servers, supports division of 1000 regions, and each region can include 200 nodes, thereby reaching the scale of 200,000 nodes online at the same time in the entire network.

[0035] The invention can switch between ...

Abstract

The invention discloses a directory distribution method and network architecture orienting to a high-concurrency retrieval system, and belongs to the field of computer network. The invention provides a retrieval method combining the integrated retrieval based on servers with the distributed retrieval based on directory distribution according to the behavior characteristics of video retrieval of users, and makes full use of the server capability of each user node to complete the update of the consistency in the directory file when the user node resource is free, so that the user can acquire data consistent with those on the retrieval server when retrieving. The user firstly searches for the required retrieval result by reading the local directory file when retrieving, and adopts the integrated retrieval based on the retrieval server when the directory file cannot meet the requirements of the user, thereby not only guaranteeing the retrieval response time and improving the user experience, but also guaranteeing the accuracy and integrity of the retrieval result. Under the pressure of high-load and high-concurrency retrieval access, the invention, which has high expandability, can obviously relieve the pressure of servers in a retrieval center, reduce the hardware input and reduce the system cost.

Description

Technical field: [0001] The achievement of the invention can be used in various large and medium-sized multimedia information retrieval systems, and can improve system performance and expandability while reducing hardware cost. By constructing a P2P overlapping network, the commonly used search information of users is organized into directory files and transmitted in the network. When users search, they only need to obtain the local directory files to complete the preliminary search, thus greatly reducing the pressure on the server. , to improve user experience. The achievement of the present invention belongs to the technical field of computer network. Background technique [0002] As people's enthusiasm for video program creation continues to rise, the quality of video program sources is improving day by day, and they tend to create and share through the Internet, as evidenced by the rapid development of video sharing sites such as Tudou.com and Youku.com.
