With the popular deployment of broadband Internet, the
requirement of Internet multimedia applications with provision
of QoS is growing rapidly. Usually, the Differentiated Service
(DiffServ) and/or Integrated Service (IntServ) are the feasible
solutions to achieve multimedia QoS applications in IP
networks. However, the static resources allocation of the
priority queues in the DiffServ networks has the impacts on
insufficient resources utilization when there is a burst in a
certain priority queue while there is starvation in other queues.
Therefore, the essential consideration in achieving a multimedia
QoS application is to adaptively maximize the resource
utilization. In the paper, we proposed the Dynamic QoS Queue
Mapping (DQ2M) algorithm to adopt the dynamic queue
scheduling control, which can adaptively maximize the
utilization of the queues and network resources based on the
soft states of the DiffServ network. Additionally, the evaluation
results show that if the channel congestion for some priority
queues is serious while there are still some unused resources of
the lower priority queue, the proposed DQ2M algorithm can
make the resources utilization of the lower priority queue more
fair and efficient.
