DiffServ is assumed as a scalable solution for service differentiation in the Internet. It applies differentiated behaviors on data packets for different quality levels on a per hop basis (PHB). However, it does not have any control on the traffic entering the network and the paths which are traversed by data packets. Therefore, if no complementary mechanism is used with DiffServ, the end-to-end service...

The SVC (scalable video coding) extension to the recent video compression standard H.264/MPEG-4 AVC paves the way for video congestion control, by allowing flexible on-the-fly adjustments of the sending rate. We study the interaction between TFRC (TCP-friendly rate control) and application level rate control, and observe that TFRC requires relatively large router buffers to keep packet loss on acceptable...
