Abstract
Streaming multimedia applications are known to consume network bandwidth in a greedy manner because they depend on the UDP transport protocol which doesn’t pay attention to resource sharing nor congestion state of the network.
In this thesis a modified version of SCTP (Stream Control Transmission Protocol) protocol is used to transfer video data.
The proposed protocol makes best use of different existing features of SCTP such as partial reliability, partial order and multiple streams.
It deploys a new algorithm that tries to share bandwidth fairly and resolves network congestion if happens by detecting congestion state of the network and adapting the transfer rate of the video data according to this congestion state. It takes into consideration the nature of MI’EG-4 oata that was encoded into 3 dilTerenttypes of frames with diflcren! weights of importance.
At the end of the thesis, simulation experiments using NS-2 show that adapting such algorithm would reduce data send rate and increase data receive rate in congestion states with little price to pay in slight delay of frames which could be compensated by deploying buffering. Such algorithm has no side effect on non-congested network during normal operations.
