This is beneficial for the server side that scales to a higher load when it doesn't have to deal with TCP. ...
The transport of streaming media data over TCP is hindered by TCP's probing behavior that results in the rapid reduction and slow recovery of the packet rates. ...
In the experiment, we compare a normal web-server streaming video with a RTP server (komssys) to a client by encapsulating the video data in HTTP packets on a IXP network card close to the video server ...

To solve this problem, we proposed a novel video cache algorithm, called the Optimal Cache (OC) algorithm, for a relay video proxy. ...
The PSC algorithm reduces the decoding errors caused by packet loss, improves error recovery, and provides QoS-guaranteed video playback. ...
The PSC algorithm effectively selects the maximum amount of high priority frame data and caches it in the relay video proxy so as to minimize packet loss and improve error recovery. ...
