Abstract
The invention discloses a method for realizing p2p-based remote video education on a webpage, and belongs to the technical field of networks. The method comprises that: a lecturer and participants open the webpage, and load flash to connect a p2p server; the p2p server allocates a key to all users; the flash sends the key and account number of the users to a session server for storage; the lecturer establishes direct connection with a plurality of users in all the users through the key, and sends audio and video to the users; and the plurality of users send the audio and video to other users in the same mode until all the users receive the audio and video. The method can realize p2p-based remote video education and network video conferences on the webpage, directly establishes connection between the lecturer and the participants, and lightens the bandwidth pressure of the server so as to improve the network communication efficiency and network utilization rate.
Description
Technical field
The invention belongs to networking technology area, specifically belong to the method that realizes on a kind of webpage based on the remote video education of p2p.
Background technology
The development of Internet technology can be stayed indoors us and has just been realized instant messaging, with good friend's chat, with affiliate's negotiation or the like.At present, the immediate communication tool that downloads and installs based on needs is as MSN, QQ, POPO has been subjected to everybody liking deeply, and it provides new approach for people's communication, information interchange, is another the important information interchange mode except that mobile phone, fixed line, Email.By these instruments, the user can realize single or many people video, can hold the network teleconference, can carry out network remote education, can also allow the interchange cost between people and the people reduce greatly, and improve efficient.But, use above-mentioned IMU tool user must download and install correspondent customer terminal software, if software has upgrading, each computer all needs upgrade software; And, all data messages (such as chat record etc.) all be retained in the computer terminal, just can't obtain legacy data information in case changed computer, very inconvenience.So people have just had such demand: need not to download and install any software, can realize instant messaging once opening webpage, and all data messages can be safely stored on the webpage.At present, also occurred the communication modes on some webpages on the network, such as message board, forum etc., still, its common deficiency is that instantaneity is too poor, can't realize webpage version audio frequency and video, is difficult to satisfy the instant demand of linking up of people.Even some software has also been realized just can realizing remote video education (as fms or red5) without down loading mounting software on webpage now, but but can not realize point-to-point video communication well, can't utilize user's bandwidth resources, cause very big server and bandwidth pressure for remote video education platform provider, cause operation cost sharply to rise along with the increase of number of users, thereby the operation scale and the scope of business of these softwares have been limited, do not possess the condition of using and promoting on a large scale, to such an extent as to the product and the company of certain market scale do not appear possessing in present webpage version remote video education.The present invention proposes that a kind of what realize is the method for point-to-point remote video education based on p2p on webpage, can realize that client do not download under the situation with high instantaneity, maximally utilise the bandwidth resources that the user leaves unused and carry out the audio-video network meeting, this will greatly make things convenient for the use of Web conference and greatly reduce and dispose the hardware and software cost that remote video education need drop into.
Summary of the invention
Technical matters to be solved by this invention is: the method based on the remote video education of p2p that realizes on a kind of webpage is provided.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: the method based on the remote video education of p2p that realizes on a kind of webpage may further comprise the steps:
1) user opens webpage, loads a flash, and flash connects the stratus server, obtains key, and key and user's number of the account is saved in conversation server;
2) all users that participate in imparting knowledge to students are saved in an array variable p;
3) flash on lecturer's browser obtains n in the array variable (n is a variable, and less than array length) individual user a (for convenience, a here is set to this n user's another name);
4) search and obtain the pairing key of a from conversation server, initiate connection request to a of key correspondence by the method for calling flash;
5) after a receives connection requests, notify the flash on lecturer's browser, the flash on lecturer's browser begins to obtain the camera and the microphone of lecturer this locality, and the audio, video data of camera and microphone is sent to a;
6) after a receives audio, video data, audio frequency and video are play in flash, and from array variable p, find out also do not have audio frequency and video n user b (for convenience, the b here is set to not have n user's of audio frequency and video another name), if the number of b is 0, then execution in step 9), otherwise carry out next step;
7) a searches and obtains the pairing key of b from conversation server respectively, initiates connection request by the method for calling flash to the b of key correspondence;
8) after b receives connection request, the flash on the notice a browser, the flash on a browser sends to b with audio, video data, and b receives behind the audio, video data and plays on the flash in the browser of b;
9) if also have the user to confiscate audio, video data among the p, then represent b with a, and continue to obtain and also confiscate n user in the audio, video data (another name is set is b) among user's array variable p, execution in step 7 then), if all users have received audio, video data among the p, then begin remote video education.
Wherein conversation server is meant described in the step 1): be used for preserving the server of the data of user's number of the account and key, described stratus server is meant: flash official provides is used for the p2p communication, distributes key to give the server of flash client.
The present invention compared with prior art has the following advantages:
(1) user need not download any software and just can realize remote video education on webpage, has saved the hardware cost of buying remote video education, has also reduced the software maintenance cost simultaneously, and integral body has reduced the use cost of remote video education;
(2) instantaneity is fine, does not have to lag behind;
(3) cross-platform, may operate on any operating system that can support browser;
(4) owing to adopted the p2p technology, can alleviate server stress and conserve bandwidth greatly, cut operating costs significantly.
Description of drawings
Fig. 1, Fig. 2 are detail flowcharts of the present invention in the Figure of description.
Embodiment
The method based on the remote video education of p2p that realizes on a kind of webpage may further comprise the steps:
