BACKGROUND

With constant development of information technologies, watching television programs or video programs has become one of the most common entertainment modes in people's lives. To improve user experience in watching video programs, video program downloading platforms emerge naturally. Users may download video programs from the video program downloading platforms by means of clients, and then watch the video programs on the clients locally.

At present, to improve a speed in downloading video programs, clients generally acquire video programs through content delivery network (CDN) servers corresponding to the video program downloading platforms, namely, the clients send video program downloading requests to the CDN servers, and the CDN servers send video programs corresponding to the requests to the clients through the Internet. However, there are many network nodes in the Internet and the number of network hops is large, which causes a low speed in downloading video programs and buffering of the video programs when they are started playing, thereby causing a lower speed in starting playing the video programs.

DETAILED DESCRIPTION

To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following clearly and completely describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure.

Embodiments of the present disclosure provide a method for acquiring a video program, which can be applied to a P2P server, as shown in FIG. 1, the method includes following steps.

101: A video program acquiring request sent by a client is received.

The video program acquiring request carries identification information of a video program and an Internet Protocol (IP) address of the client. The identification information of the video program can be a name of the video program or can be an identity (ID) of the video program, which is not limited in the embodiments of the present disclosure. The client can be a mobile phone, or can be a computer or a tablet computer, etc. The IP address of the client can be 192.1.1.183. In a P2P network, various nodes are equal peer nodes, where each node not only can obtain services from other nodes but also can provide services to other nodes.

102: Identification information of a router whose public IP address is identical to the IP address of the client is acquired from a preset router list.

The preset router list preserves identification information of a plurality of routers and a public IP address corresponding to each router. The identification information of a router can be a name such as Xiaoming of the router, or can be an ID of the router, which is not limited in the embodiments of the present disclosure. If the public IP address of a router is the same as the IP address of the client, this indicates that the router and the client are positioned in the same LAN. At the moment, the client downloads video programs by means of the router. In this way, a number of network hops can be reduced, and a speed in downloading video programs can be improved, thereby improving a speed in starting playing video programs.

103: It is determined whether the identification information of the video program is present in a video program list corresponding to the identification information of the router.

Identification information of different video programs is preserved in the video program list. A video program corresponding to the identification information of the video program in the video program list is downloaded by the router from a CDN server. A process of downloading a video program by the router from the CDN server may be specifically as below: a video program list sent by the CDN server is received, the video program list preserves identification information of a plurality of video programs; a video program downloading request is sent to the CDN server according to the identification information of the video program so that the CDN server sends a video program corresponding to the identification information of the video program to the router. When storage space of the router is full, requesting to download video programs from the CDN server is stopped, and a downloaded video program list is sent to the P2P server.

It is to be noted that a large number of video programs are cached in the CDN server, and the CDN server can perform statistical calculation on currently popular video programs in the form of a list, and then send the popular video programs to the router. For example, the currently popular video programs include: a video program 1-a video program 100. The CDN server sends identification information respectively corresponding to the video program 1-the video program 100 to the router in the form of a video program list. After receiving the video program list, the router can download popular video programs according to order from top to bottom from the video program list until the storage space of the router is full. For example, the storage space is full when the router downloads from the video program 1 to the video program 80. At the moment, the router sends identification information respectively corresponding to the downloaded video program 1-the video program 80 to the P2P server.

To the embodiments of the present disclosure, after Step 103, the method specifically may further include: sending prompt information to the client if the identification information of the video program is present in the video program list corresponding to the identification information of the router, where the prompt information is used for prompting the client to request to acquire the video program from the CDN server. A specific content of the prompt information may be empty. By sending the prompt information to the client, a user can timely learn about acquiring a video program. When a requested video program is not present in the router, the user can download the video program in other ways. For example, the user can acquire the video program from the CDN server. In this way, user experience can be improved.

104: The identification information of the router is sent to the client if the identification information of the video program is present in the video program list corresponding to the identification information of the router.

Further, it is convenient for the client to request to acquire the video program from the router corresponding to the identification information.

For example, the router whose public IP address is the same as the IP address of the client is a router 1, the video program requested by the client is a video program 1, if identification information of the video program 1 is present in the video program list corresponding to the router 1, the P2P server sends the identification information of the router 1 to the client so that the client can request the video program 1 from the router 1.

Embodiments of the present disclosure provide a method for acquiring a video program. A client downloads video programs from a router whose public IP address is the same as an IP address of the client, namely, the client downloads video programs by means of the router.
