Problems solved by technology

[0006] The main problem of the first solution is that the number of shared nodes is too small, and if the original upload node is not online, the network cannot provide the media service at all
Although the second solution solves the problem of the first solution, it needs to record while watching, and the processing and storage costs are also very high, which is likely to cause the user's disgust, and then cause the user to delete or transfer the recorded media after watching. content
Therefore, it is not an ideal storage solution
At the same time, neither of the two schemes can guarantee that the published content can get guaranteed service, and only when the user with the content is online, other users can get the content service

Embodiment Construction

[0032] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, the system divides the media file into segments, and divides a media file into segments 1 to n, where n represents a natural number.

[0034] The segments of each media file can be independently stored in each central office node. Here, the imported central office nodes include central office node 1 to central office node m, where m represents a natural number. Segment 1 to segment N are respectively stored on central office node 1 to central office node m, and the original copy of each media file segment must be stored on one central office node to ensure service.

[0035] Such as figure 2 As shown, the media gateway is connected between the backbone network and the metropolitan area network, and multiple user nodes and multiple central office nodes are connected through the metropolitan area network....

Abstract

A method for storing VOD media files in peer to peer network, includes the following steps: the media file is segmented; the peer to peer network have at least one local office node, which stores the media file in segments; each segment of the media file is stored in at least one office node; the local office nodes are partitioned to multi areas, and every area sets at least one media gateway, this media gateway manages the storing status of segmented media files in current area. A system for storing VOD media files in peer to peer network is disclosed. The present invention stores media files in segments, user node does not need to store the whole media file, and only stores some segments of media file; the storage of a large media files is finished by the operation of multi nodes; the record and storage cost of the user node is lightened effectively.

Description

technical field [0001] The present invention relates to a peer-to-peer network (Peer To Peer Network, hereinafter referred to as P2P) and broadband streaming media technology, in particular to a storage method for peer-to-peer network video-on-demand media and a media-on-demand system. Background technique [0002] With the rapid development of the Internet and broadband access networks, the use of P2P technology has been able to successfully carry out large-scale video media downloads and live broadcasts on the Internet. However, there are still many problems in the large-scale development of P2P on-demand services, among which media storage is one of the problems. [0003] In the existing P2P on-demand system, there are mainly the following two storage solutions: [0004] 1. The original upload node saves a complete piece of media data. General user nodes do not store media data on the disk, but only cache a small part of the data in memory during playback. User nodes can...
