Abstract: | The growing needs of multimedia communications are leading to
new developments in providing real-time communication with guarantees.
Several extensions
have been proposed for different layers of the
Open Systems Interconnection Reference
Model to accomodate these
needs. In this paper, we study methods for guaranteeing delay jitter
bounds for high-speed networks in the network and application layers of
this model. The method proposed for the network layer
provides distributed jitter control. The method proposed
for the application layer allows the destination application to control
delay jitter. We use a simulation to compare the effects on delay
jitter in each
method for various scenarios, such as constant bit rate,
cross traffic, and bursty data. In addition, the buffer space
requirements for accommodating real-time channels are monitored at
each node in the network. |
