Video peer-to-peer stream exchange method, system and device

Abstract

The invention provides a video peer-to-peer flow exchange method, system and device, which are characterized in that each server node is set to adopt a peer-to-peer network structure, hierarchy is not distinguished, local storage of each server node is gathered into a virtual shared storage, and decentration is realized. The full links between the server nodes and the user nodes are set to communicate by adopting a real-time audio protocol, so that the time delay and the calculation cost of the distribution network are reduced. A subscription push mechanism is established, when a user requests video data, a preset user perception guarantee algorithm is adopted to calculate a correlation score between a current user node and a user node which has obtained specified video data, and the user node with relatively high correlation is selected as an associated user node for subscription. And the associated user node directly pushes the video data to the current user node, so that the network delay is greatly reduced, and the user experience quality is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of network video transmission, in particular to a video peer-to-peer stream exchange method, system and device. Background technique [0002] In recent years, the scale of network video transmission traffic has grown unprecedentedly. As an intuitive and vivid content presentation, video has gradually occupied the mainstream of domestic network content and pushed China's video transmission traffic to the forefront of the world. Faced with the huge growth of video content data, network video transmission technology is facing more severe challenges, especially for real-time video transmission systems that require low latency. [0003] On the other hand, the network transmission system has developed rapidly in recent years. From the traditional tree-like centralized distribution network, to the cloud-network interconnection architecture of all-cloud deployment, and then to the multi-platform federation a...

Problems solved by technology

The network video streaming transmission technology based on the central distribution architecture of CDN (Content Delivery Network, content distribution network) is difficult to meet the increasingly large scale of content

There is a multi-level long-path back-to-source mechanism, which will cause a large network delay; the tree structure is limited to one-way forwarding, which makes it difficult to support two-way video streaming; multi-stage transmission protocols are heterogeneous, poor in universality, and difficult to adapt to rapid changes in business needs ; The control platform is centralized in the center, and fine-grained control cannot be achieved
