1. A method for prioritizing a packet received at a router in a network, the method comprising the steps of:
- a. determining whether the packet is delay-sensitive;
b. if the packet is delay-sensitive, estimating a delay variation of the packet;
c. if the packet is delay-sensitive, using the delay variation of the packet to prioritize the packet for transmission from the router.

Abstract
The present invention provides a system and method for prioritizing delay-sensitive packets relative to each other for transmission from a router in a network, based on a delay variation estimated for each delay-sensitive packet by a quality of service monitor. In accordance with the present invention, late delay-sensitive packets are assigned a higher priority than, and are transmitted before, other delay-sensitive packets, thereby reducing the level of jitter and improving the quality of the packet streams that comprise late delay-sensitive packets.
