1. A method comprising:

  • providing pseudo-streaming media data to a terminalreceiving a transport control protocol (TCP) acknowledgement from the terminal;

    estimating one or more network conditions of a network using the TCP acknowledgment;

    determining an optimal session bitrate using the estimated one or more network conditions, wherein determining the optimal session bitrate further comprises;

    determining stability criterion using the estimated one or more network conditions, wherein determining stability criterion includes at least one of;

    comparing a media time in transit and a round trip time estimate, andcomparing a bitrate received with a current bitrate session; and

    determining the stability of the media network; and

    providing the optimal session bitrate based at least in part on the media-network-stability determination; and

    providing pseudo-streaming media data to the terminal according to the optimal session bitrate.
