1 Jitter Control in QoS Networks Yishay Mansour Dept. of Computer Science Tel-Aviv University and AT&T Research Labs Boaz Patt-Shamir Dept. of Electrical Engineering Tel-Aviv University and Northeastern University Hung, Kuo-EnNTHU/CS, Visual Communication Lab.

2 Outline Introduction Model Delay-jitter control –Off-line delay-jitter control –On-line delay-jitter control Distribute delay-jitter control

3 Introduction Delay-jitter –Bounds the maximum difference in the total delay of different packets.

4 Model Jitter-control algorithm Packet arrival sequencePacket release sequence Sequence of packet: 0, 1, 2…n : k Arrival time: a(k)
