A Low Cost Multicast Routing Algorithm with Delay and Delay Variation Constraints;

Delay constraints and delay variation constraints must be taken into account for interactive real-time application such as video conferences.

Topology inference technique based on delay jitter;

An adaptive media playout (AMP) scheme was developed which adaptively follows changes of the network delay to reduce the effect of delay jitter on the visual quality.

In order to meet these requirements of long lifetime, reliability in a wide voltage range, small delay time, as well as small delay jitter, the triggered devices based on semiconductor ZnO and high dielectric BaTiO3 ceramic surface flashover devices were designed, their characteristics were investigated.

Delay and delay variation constraints must be taken into account for interactive real-time application such as video-conferences.

Utilizing its capability of searching the shortest route,proposed a QoS multicast routing algorithm based on ant colony system to solve the delay and delay variation constrained multicast routing problem.

A novel model is proposed to construct widest available-bandwidth multicast tree under the constraints of end-to-end delay,delay variation and packet-loss rate,in which available bandwidth is really considered as prime metric.

The concept of jitter is briefly introduced, and the methods for eliminating the jitter are analyzed.

The concept of jitter and the actual ATM switch queue are briefly introduced.

The quality of real-time packet voice is unacceptable due to packet loss and delay jitter.
