A mechanism for transmitting packetized audio over wide area, shared networks is presented and its performance is studied via simulative analysis. The proposed mechanism does not need ``in advance'' allocation of either network bandwidth or computing resources, but maintains satisfiable values of the tradeoff between the audio packet playout delay and the packet loss due to late arrivals. Because of this, the proposed mechanism may be profitably integrated in industrial environments with other hard real time applications for which, instead, resource allocation is desirable. The performance of the proposed mechanism (i.e. the percentage of audio packets that arrive on time for being played out at the destination during an audio communication) is analyzed via simulation by a stochastically timed process algebra based software tool termed TwoTowers.

Abstract
A mechanism for transmitting packetized audio over wide area, shared networks is presented and its performance is studied via simulative analysis. The proposed mechanism does not need ``in advance'' allocation of either network bandwidth or computing resources, but maintains satisfiable values of the tradeoff between the audio packet playout delay and the packet loss due to late arrivals. Because of this, the proposed mechanism may be profitably integrated in industrial environments with other hard real time applications for which, instead, resource allocation is desirable. The performance of the proposed mechanism (i.e. the percentage of audio packets that arrive on time for being played out at the destination during an audio communication) is analyzed via simulation by a stochastically timed process algebra based software tool termed TwoTowers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
