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.
