| For the last few years, many classifications and marking strategies have been proposed with the consideration of video streaming applications. According to IETF recommendation, two groups of solutions have been proposed. The firts one assumes that applications or IP end points pre-mark their packets. The second solution applies the router which is topologically closest to video source. It should perform Multifield Classification and mark all incomming packets. This paper investigates the most popular marking strategies belonging to both mentioned above groups of solutions. The pre-marking strategies based on H264 coder extensions are simulated based on NS-2 network simulator and Evalvid-RA framework. The results are compared with the IETF recommendations for video traffic shaping in the IP networks and marking algorithms proposed by other researchers |
