Abstract

An objective of the present invention is to provide a method and apparatus for video transmission, wherein the video is initially stored in one or more other network devices. The method comprises receiving a second request for a video from a user equipment; forwarding the second request to other network device corresponding to the second request; determining a manner of obtaining the video based on a response, received from the other network device, to the second request; and transmitting the video obtained based on the manner of obtaining the video to the user equipment. Compared with the prior art, by uniformly determining a manner of obtaining a video and transmitting the obtained video to the user equipment the present invention, the present invent on lowers deployment difficulty, reduces bandwidth resource demands, and enhances the video sharing degree.

Claims

1. A method for video transmission in a network device, wherein the video is initially stored in one or more other network devices, wherein the method comprises:

receiving a second request for a video from a user equipment;

forwarding the second request to an other network device corresponding to the second request;

determining an obtaining manner for the video based on a response to the second request as received from the other network device;

sending the video obtained based on said obtaining manner for the video to the user equipment,

wherein the user equipment sends a first request for the video to the other network device.

2. The method according to claim 1, wherein the receiving a second request for a video from a user equipment comprises:

receiving a second request for the video from a user equipment, said second request being transmitted based on a response of the other network device to a first request by the user equipment for the video on said other network device.

3. The method according to claim 1, wherein the determining an obtaining manner for the video based on a response to the second request as received from the other network device comprises:

determining identification information of the video based on a response to the second request as received from the other network device;

determining whether the video is stored locally based on the identification information;

determining an obtaining manner for the video based on the result of determining whether the video is stored locally.

4. The method according to claim 3, wherein the determining identification information of the video based on a response to the second request as received from the other network device comprises:

obtaining video content for determining identification information of the video from video header information included in the response, wherein the video content has a first length;

determining a Hash value obtained from calculation based on the video content as the identification information of the video.

5. The method according to claim 4, further comprising:

setting a value of the first length based on a video type.

6. The method according to claim 3, further comprising:

storing the video locally based on times of second request for the video by respective user equipments within a first time threshold and based on the identification information.

7. The method according to claim 3, further comprising:

removing the video from local storage based on times of second request for the video by respective user equipments within a second time threshold and based on the identification information.

8. The method according to claim 1, wherein the obtaining manner for the video comprises any one of the following:

obtaining the video from said network device locally;

obtaining the video from said other network device.

9. An apparatus for video transmission in a network device, wherein the video is initially stored in one or more other network devices, wherein the apparatus comprises:

at least one processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least;

receive a second request for a video from a user equipment;

forward the second request to an other network device corresponding to the second request;

determine an obtaining manner for the video based on a response to the second request as received from the other network device; and

send the video obtained based on the obtaining manner for the video to the user equipment,

wherein the user equipment sends a first request for the video to the other network device.

10. The apparatus according to claim 9, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

receive a second request for the video from a user equipment, said second request being transmitted based on a response of the other network device to a first request by the user equipment for the video on said other network device.

11. The apparatus according to claim 9, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

determine identification information of the video based on a response to the second request as received from the other network device;

determine whether the video is stored locally based on the identification information; and

determine an obtaining manner for the video based on a result of determining whether the video is stored locally.

12. The apparatus according to claim 11, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

obtain video content for determining identification information of the video from video header information included in the response, wherein the video content has a first length; and

determine a Hash value obtained from calculation based on the video content as the identification information of the video.

13. The apparatus according to claim 12, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

set a value of the first length based on a video type.

14. The apparatus according to claim 11, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

store the video locally based on times of second request for the video by respective user equipments within a first time threshold and based on the identification information.

15. The apparatus according to claim 11, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to:

remove the video locally based on times of second request for the video by respective user equipments within a second time threshold and based on the identification information.

16. The apparatus according to claim 9, wherein the obtaining manner for the video comprises any one of the following:

obtaining the video from said network device locally;

obtaining the video from other network device.
