Abstract
This paper proposes a new topological design method, named BXCQ,
which optimizes logical network configuration while
guaranteeing Quality-of-Service (QoS) requirements for each service
class in an ATM network. The BXCQ method determines the optimum
logical network topology associated with each service class so as to
minimize network cost. In our previously proposed Full-Net
architecture, these different logical topologies can be suitably
mapped at the same time on the same ATM physical network by using the
Virtual Channel Handler (VCH) to create different logical
interconnection networks. The BXCQ method allows us to clarify the
relations between multimedia traffic characteristics and desirable
logical network configurations in Full-Net. Evaluation results suggest
that a service class that is bursty, delay tolerant, and cell loss
sensitive with small demand should be supported by a loop-like
topology. This study will be useful for designing flexible and
cost-effective multimedia networks that can also adapt to
not-yet-known services.
