Abstract:
1. A method of sending hypertext transfer protocol (HTTP) adaptive streaming (HAS) content from a content source to a client over a transmission control protocol (TCP) connection between the content source and the client, the method comprising: measuring network delay values of the TCP connection; determining a size of a starting TCP congestion window (cwnd) based on the measured delay values; receiving a request for one or more first HAS data chunks from the client; sending the one or more first HAS data chunks from the content source to the client over the TCP connection; receiving a request for a second HAS data chunk from the client; and sending the second HAS chunk from the content source to the client over the TCP connection using the starting cwnd, wherein the network delay values include idle delay values indicating an amount of delay in the TCP connection during an idle time period, the idle time period is a time period over which no HAS data chunks are being sent from the content source to the client, and determining the size of the starting cwnd includes setting the size of the starting cwnd based on the idle delay values.
