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...
