On Jitter and Reassembly Bu ers in De ection Networks

چکیده
We investigate experimentally the performance of deeection networks for stream-oriented, jitter-sensitive traac. It is a common belief that pure deeection networks are not suitable for real-time jitter-sensitive application, and networks based on a connection-oriented paradigm are the only solution is such cases. We argue to the contrary and present simulation results supporting our claims.

متن کاملThe E ects of High - Performance Processors , Real - Time Priorities and High - Speed Networks on Jitter in a Multimedia Stream
Multimedia applications have the potential to enhance work for teams of users collaborating across distances. Jitter hampers the e ectiveness of these multimedia applications. Jitter is the variation in the end-to-end delay of data sent from one user to another. Jitter can cause silent gaps in the playout of an audio stream such as in an audioconference, or a choppy appearance to a video stream...
متن کاملDecoder Bu er Modeling and Simulation for End-to-End Transport of MPEG2 Video with ATM Network Jitter
In this paper, the operation of MPEG-2 decoder bu er is modeled and simulated when a VBR MPEG2 stream is delivered through an ATM network with jitter. End-to-end packet based analysis is performed for delivery of MPEG-2 transport streams over ATM networks. A novel approach to analyzing the decoder bu er in the presence of network jitter is given in this paper. The probability density function o...
متن کاملOn the Impact of Long-Range-Dependent Tra c in Dimensioning ATM Network Bu er
Recent measurements of packet networks have shown that packet tra c exhibits long-range-dependent property. Studies have also discovered that this property is not adequately captured by the conventional Markov tra c models and often yields queueing behavior such as heavy-tailed or subexponential queue length distribution. These ndings have led to the implication that long-range-dependent tra c ...
متن کاملImpact of VC Merging on Buffer Requirements in ATM Networks
For the implementation of multipoint-to-point connections in ATM, various approaches exist, each with its own advantages and disadvantages. VP-based methods require unique sender identi cation but they do not require reassembly in merging points. In contrast, VC-based methods do not require unique sender identi cation but they do require reassembly in merging points. It is likely that VC mergin...
