Abstract:

According to the jitter of the time division multiplexing services of the packet transport network, a random packaging mode and a fixed packaging mode are presented. Two math models for single node and the end-to-end serial path are established. The influence of network parameters, such as background traffic, path node number, node throughput and packaging model is studied. Present results indicates that the delay jitter could be reduced by optimizing these parameters which could provide the basis for configuration of the jitter buffer. The model of fixed packaging has a stronger ability to resist jitter than the model of random packaging.

Key words: packet transport network, time division multiplexing, jitter, packaging
