Abstract: A new approach for bandwidth allocation and congestion control is reported in this paper, which
is of the Rate Controlled admission with Priority Scheduling service type. It is called Dynamic Time
Sharing (DTS), because of the dynamic nature of the procedure for resource partitioning to allocate
and guarantee a required bandwidth for every traffic class. This approach is based on guaranteeing specific
traffic parameters (bandwidth requirements) through a policing unit, and then optimizing the
bandwidth assignment within the network for specific parameters of interest (like delay or jitter, and
loss). The optimization process is based on the parameters guaranteed by the policing unit. A batch
admission policy is used at the edges of the network according to a specific framing strategy to follow
the traffic characteristics (e.g., the traffic constraint function) of different traffic classes. On the other
hand, another framing (congestion control) strategy is used within the network, which is based on different
(delay/loss) requirements of the traffic classes. Proper management of bandwidth and buffer
resources is provided in every (switch) node of the network, such as to guarantee the diverse performance
of interest.
