Problems solved by technology

[0003] However, when there is a new popular video resource that has just come online (that is, the network device has just been released), since there is no such new popular video resource in all P2P nodes, a large number of users simultaneously request the network device to obtain the popular video resource. This poses a serious challenge to the load capacity of network equipment
Moreover, since most network devices do not have the ability to respond to such a large number of user requests at the same time, many requesting users cannot access the popular video resource at the first time, or often experience freezes or long buffering times when playing the popular video resource

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] figure 1 It is a schematic diagram of the P2P system according to the present invention. Such as figure 1 As shown, the P2P system includes a network device 1 and a plurality of P2P nodes 2; wherein, the network device 1 includes but not limited to a network host, a single network server, a collection of multiple network servers or a collection of computers based on cloud computing, wherein cloud computing It is a kind of distributed computing, a super virtual computer composed of a group of loosely coupled computers.

[0023] The network device 1 is equipped with a resource pushing device 10 for pre-pushing video resources to P2P nodes. Optionally, the resource pushing device 10 may be installed in one or more devices in the network device 1 . Herein, unless otherwise specified, the network device 1 and the resource pushing device 10 are used equa...

Abstract

The invention aims to provide a method and a device for pre-pushing a video resource to P2P (peer-to-peer) nodes. The method comprises the following steps: according to heat related attributes of the video resource, extracting heat characteristic information of the video resource by network equipment; on the basis of the heat characteristic information, determining whether the video resource meets predetermined heat conditions; and when the video resource meets the predetermined heat conditions, pushing the video resource to at least one P2P node. Compared with the prior art, according to the invention, when a great amount of users subsequently and simultaneously request the network equipment to access the hot video resource, the P2P nodes also can provide the hot video resource to other requesting nodes, so that the load pressure of the network equipment is greatly relieved and the user experience is obviously promoted, for example, the play pause or buffering time and the like are reduced.

Description

technical field [0001] The present invention relates to the field of P2P technology, in particular to a technology for pre-pushing video resources to P2P nodes. Background technique [0002] In the existing P2P-based video-on-demand technology, only when a user orders a certain video resource, the video resource will be stored in the user's user equipment (that is, a P2P node), and will be provided to other P2P nodes in the future. video resources. [0003] However, when there is a new popular video resource that has just come online (that is, the network device has just been released), since there is no such new popular video resource in all P2P nodes, a large number of users simultaneously request the network device to obtain the popular video resource. This poses a serious challenge to the load capacity of network equipment. Moreover, since most network devices do not have the ability to respond to such a large number of user requests at the same time, many requesting u...
