Embodiment Construction

[0051] The live video matchmaking method and system of the embodiment of the present invention are characterized in that:

[0052] (1) By matching the video demand side with the video provider, provide the video demand side to watch the live broadcast service. That is to say, the video requester sends a channel request (Channel Request), and after receiving the channel request, the video provider transmits the relevant video stream to the SDN network. Therefore, the video requester can select and watch video streams in the network.

[0053] (2) The SDN device at the network edge (Edge) converts and synthesizes the video stream in the SDN network according to the selection of the video demand side to form a virtual channel (Virtual Channel) to provide live broadcast services.

[0054] (3) According to the real-time available resources of the network and the load capacity of each node, an improved optimized forwarding path (Optimized Forwarding Path, OFP) algorithm (that is, OF...

Abstract

A live video matchmaking system. One of the live matchmaking modules of the system provides a matchmaking service between a video demander and a video provider. One of the programming modules of the system dynamically adjusts the live broadcast service provided by the edge device based on Software-Defined Networking (SDN) according to the real-time available resources of the network. One of the boundary service modules of the system dynamically converts multiple video streams according to the matching results and combines them into virtual channels according to requirements, so as to provide flexible live channel services.

Description

technical field [0001] The present invention relates to a live video matchmaking method and system based on Software-Defined Networking (SDN). Background technique [0002] Network transmission technology is changing with each passing day, and the network bandwidth provided by Internet Service Providers (Internet Service Providers, ISPs) is getting larger and larger, so everyone can act as a video provider. Compared with traditional live broadcast (Live) applications, the amount of uploaded video data is quite huge, but the network bandwidth cannot be expanded without limit, so the upload bandwidth will become a bottleneck. [0003] Known technologies include using a peer-to-peer (Peer-to-Peer, P2P) communication architecture and a client-server (Client-Server) architecture to achieve the purpose of webcasting. [0004] The P2P communication architecture can make the delay (Latency) smaller. However, when the number of clients increases, the load of each node in the mesh n...
