Abstract

The invention relates to a real-time video delivery system and method based on mobile subscribers. The system comprises a control layer and a data layer, wherein the control layer comprises an SDN controller; the data layer is used for receiving scheduling result forwarding data of the control layer and maintaining a video content; the method is applied to the control layer and comprises the following steps of obtaining real-time video requests of the mobile subscribers to form one group of video delivery sessions; configuring session data streams, carrying out space and spectrum scheduling and combining with session-based routing constraints to obtain a scheduling result; and sending the scheduling result to the data layer. According to the system and the method, the requirements of the mobile subscribers for diversity and flexibility of real-time video demands are satisfied, the flexible control of traffic is realized and the effective resource management and the resource allocationoptimization are carried out according to the network environment change.

Description

technical field

[0001] The invention belongs to the technical field of real-time video distribution network, and in particular relates to a real-time video distribution system and method based on mobile users. Background technique

[0002] In recent years, emerging video services have led to a substantial increase in Internet traffic. In 2015, global video traffic accounted for 70% of all consumer Internet traffic and will reach 82% in 2020. With the development of the mobile Internet, mobile users will become the main consumers of Internet video; for example, as the fourth largest Internet traffic producer, Twitch provides more than 150 billion minutes of live video every month, which are generated by mobile users. Therefore, it is a challenging task to satisfy the explosive demand of mobile users for real-time video.

[0003] Video delivery network (Video Delivery Network, VDN for short) service has attracted much attention as a main video content distribution mode. Howe...

Examples

Embodiment 1

[0071] The purpose of Embodiment 1 is to provide a real-time video distribution system based on mobile users.

[0072] In order to achieve the above object, the present invention adopts the following technical scheme:

[0073] Such as figure 1 as shown,

[0074] A real-time video distribution system based on mobile users, the system includes: a control layer and a data layer;

[0075] The control layer includes an SDN controller with a VDN global view to collect mobile user requests and schedule wireless spectrum resources; configure session data streams, perform space and spectrum scheduling, and combine session-based routing constraints to obtain scheduling results and send scheduling results to said data layer;

[0076] The data layer is used to receive the scheduling result forwarding data of the control layer and maintain video content.

[0077] In the present invention, a new VDN model system for video distribution network is proposed, S-VDN, and SDN controller is an...

Embodiment 2

[0097] The purpose of Embodiment 2 is to provide a real-time video distribution method based on mobile users.

[0098] In order to achieve the above object, the present invention adopts the following technical scheme:

[0099] Such as Figure 5 as shown,

[0100] A real-time video distribution method based on mobile users, the method is applied to the control layer, including:

[0101] Step (1): Obtain the real-time video request of the mobile user to form a group of video distribution sessions;
