Abstract |
The evolution of optical technology has resulted in
the emergence of several promising paradigms so as to
realize the next generation Internet backbone
infrastructure. Among all the existing switching
techniques, optical burst switching (OBS) has shown to
support the bursty nature of diverse IP traffic classes
more efficiently. Nevertheless, with increase in realtime
applications over the Internet, devising
mechanisms that guarantee quality of service (QoS)
and efficient bandwidth utilization within the OBS
network has become a major endeavor. In the
literature, resource allocation-based QoS management
has been investigated as a possible solution to
overcome this necessity. However, to the best of our
knowledge, the resource-based technique has not been
analytically studied for any arbitrary number of traffic
classes taking both, wavelengths and fiber delay lines
(FDLs) into account. In this paper, we present a novel
mathematical model for the resource-based approach
with two service classes namely, real-time (H) and non
real-time (L) classes. We then extend the model to
cover any number of classes. The effectiveness of the
model is justified through simulation experiments. |
