Abstract
A network node, and a method for operating a network node, such as a base station, may transmit multiple video streaming sessions from servers to clients in terminal nodes and can estimate client-side video buffer occupancy levels associated with the streaming sessions. To estimate a client-side video buffer occupancy level, the network node analyzes packets communicated with the terminal nodes to identify application layer messages and extract transaction information, determine payload types associated with objects conveyed in the packets identified with application layer messages, and associate the objects conveyed in the packets identified with application layer messages with one of the streaming sessions. The network node may use the estimated video buffer occupancy levels to determine scheduler parameters for use in scheduling packets for transmission to the terminal nodes. Packet scheduling may also be based on quality of experience considerations associated with streaming session clients in the terminal nodes.
