In one example embodiment, a method of adaptive video streaming includes receiving, by a server, a request for a video segment from an end user device and determining, by the server, a plurality of variables, the plurality of variables including at least one of a download time of a previously requested video segment by the end user device, a fullness of a buffer at the end user device and a size of the buffer. The method further includes determining, by the server, a rate of the requested video segment based on one or more of the determined plurality of variables and sending, by the server, the requested video segment at the determined rate to the end user device.

System and method for enabling network based rate determination for adaptive video streaming

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 may include receiving a request for one or more first HAS data chunks from the client; sending the one or more first HAS data chunks to the client; generating idle delay values indicating an amount of delay in the TCP connection during an idle time period, the idle time period being a time period over which no HAS data chunks are being sent from the content source to the client; receiving a request for a second HAS data chunk from the client; setting the size of a starting TCP congestion window based on the idle delay values; and sending the second HAS chunk to the client using the starting TCP congestion window.
