Abstract
One of the major hurdles in optical burst-switched (OBS) networks is
the contention problem. In this paper, we tackle this problem by proposing
a new contention resolution technique based on control packet buffering. In
particular, a rigorous mathematical model is developed to analyze the performance
of an OBS network core node employing this technique along with just-in-time
one-way reservation protocol. The key idea that makes this proposal novel
is that this buffering is implemented in the electronic domain, thus avoiding
the complexity that exist in the optical domain solutions. A detailed evaluation
of the system performance using both the burst loss probability and the steady-state
throughput is presented. Our results reveal that a considerable improvement
in the performance is achieved when adopting the proposed technique.
