Abstract :
We present an application layer quality of service (QoS) control protocol (QCP), which employs an additive-increase bandwidth feedback algorithm. The protocol enhances the communication between end nodes and "the network" by a QoS packet sent from the source for per n video frames. The destination calculates the delay jitter, throughput for per QoS interval, and sends a backward QoS packet to the source. Upon the receipt of a QoS packet, the source use the delay and the bandwidth contained in the QoS packet to adjusts its sending rate. The protocol is well suited for real-time rate-adaptive video streams. The primary goal is to be easy to implement and provide an efficient application layer QoS control. Through extensive simulations, we conclude that the protocol could be able to control the jitter, delay and loss very efficiently.
