MANAGER FOR DASH MEDIA STREAMING

摘要

Client devices streaming content adhering to the Dynamic Adaptive Streaming over HTTP (DASH) standard may send Quality of Experience (QoE) information to a DASH manager and request server status updates from the DASH manager. The server status updates may include information regarding one or more content servers including online status information, content availability, load, and content server recommendations. The content server recommendations may be a relative ranking of servers that the DASH manager recommends that the client device select as a source server for desired media content. Based on the server status update information, the client may select a source server. The QoE information sent to the DASH manager may be used by the DASH manager, along with server status information, to generate the relative ranking.
