Abstract
The invention relates to the technical field of information and communication, in particular to a dynamic routing method and a device for a live video distribution network. In the live video distribution network, when a user client requests to receive some live video service, a service management system (SMS) produces a corresponding user access route setup notification message according to access requirements of a user, and puts forward to a video distribution network global server. The video distribution network global server allocates an edge node server according to location, type and the like of the user client, the edge node server is used for supplying the requested live video service forwarding service for the video distribution network global server, and an access uniform resource locator (URL) of the edge node server is supplied for the user client which requests service through the SMS. The video distribution network global server sends a route setup request message to the edge node server, informs the edge node server to be established on the user access route of the user client, and supplies a forward service of a designated live video service.
