Abstract
The invention discloses an on-line video-on-demand system based on P2P, comprising a server terminal and client terminals. The server terminal comprises a secret key providing server, a Tracker server of the BT protocol, and an NAT boring server. Each client terminal is composed of a Proxy process and a player process. Each Proxy process establishes connection with the Tracker server of the BT protocol and an Internet through a BitTorrent P2P protocol so as to obtain encrypted video data. Each player process communicates with the Proxy process through a hyper text transport protocol (HTTP) and communicates with the secret key providing server through hyper text transport protocols (HTTPS) to obtain a secret key. The Proxy processes also communicate with the NAT boring server which is in charge of NAT traversal communication with the two client terminals. The on-line video-on-demand system based on P2P performs one-time static encryption of video files at a background, and distributes the video files to users through P2P; and secret keys required for videos on demand are obtained from the secret key providing server.
Description
Technical field
The invention belongs to the video on demand techniques field of educational applications, be specifically related to a kind of online request system based on P2P.
Background technology
Along with the development of science and technology, video on demand techniques is widely applied in each medium, and also spread in education sector, the central role of video in education is that everyone admits simultaneously; It can present sound and picture simultaneously, can reach the effect of 90% of On-the-spot Interaction teaching; Add the instant messaging of network, the interaction of social networks and human contact, is main contents carrier, social activity etc. based on the Internet with video, and instant messaging is that the long-distance education of main communation means constantly developing.
The video technique of existing IT circles, be all be conceived to the contents such as traditional telecine, the making of video needs video camera as the most original input pickup; Popular video format, as mp4, wmv, rmvb, flv etc., starts, in order to these video-on-demand service in design; The network video-on-demand platform set up around these video techniques, as pplive, ppstream, be in fashion network, a sudden peal of thunder is looked at, their business model is all provide various entertainment for user, and rely on advertisement charging, profitable offering is more single.
Summary of the invention
(1) technical problem that will solve
For solving the problem, the present invention proposes a kind of online request system based on P2P, video file is disposable static encryption on backstage, is distributed to user by P2P; The key that program request needs must be unified to obtain from key providing server.
(2) technical scheme
Online request system based on P2P of the present invention, comprises server end and client;
Described server end comprises key providing server, the Tracker server of BT agreement, NAT burrow server;
Client is made up of Proxy process and player process; Described Proxy process is set up by the Tracker server of BitTorrent P2P agreement and the Internet and BT agreement and is contacted, and obtains enciphered video data; Described player process is communicated with Proxy process by http agreement, is responsible for user circle and video playback and management; Described player process also carries out communication with key providing server by HTTPS agreement, obtains key; Described Proxy process also be responsible for two clients and carry out NAT that NAT the penetrates communication server that burrows and communicate.
Further, described player process is also provided with ca authentication certificate with communicating between key providing server.
Further, described key by between user's input point sowing time, machine code, the user name and password four elements form, and issues client after encryption.
Further, described Proxy process and player process are on the same device.
(3) beneficial effect
Compared with prior art, it has following beneficial effect in the present invention: the online request system based on P2P of the present invention, by video file on backstage disposable static encryption, be distributed to user by P2P; The key unification needed during program request obtains from key providing server; Make operator have more profitable offering, also ensure that the fluency of video simultaneously.
Accompanying drawing explanation
Fig. 1 is general frame schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the online request system based on P2P of the present invention, comprises server end and client;
Described server end comprises key providing server, the Tracker server of BT agreement, NAT burrow server;
Client is made up of Proxy process and player process; Described Proxy process is set up by the Tracker server of BitTorrent P2P agreement and the Internet and BT agreement and is contacted, and obtains enciphered video data; Described player process is communicated with Proxy process by http agreement, is responsible for user circle and video playback and management; Described player process also carries out communication with key providing server by HTTPS agreement, obtains key; Described Proxy process also be responsible for two clients and carry out NAT that NAT the penetrates communication server that burrows and communicate.
Wherein, described player process is also provided with ca authentication certificate with communicating between key providing server; Described key by between user's input point sowing time, machine code, the user name and password four elements form, and issues client after encryption; Described Proxy process and player process are on the same device.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
