Abstract
The amount of bursty Internet traffic leads to
develop new architectures and technologies, such as Optical
Burst Switching (OBS), to efficiently satisfy future bandwidth
requirements. Burst loss probability is an important quality
of service metric for OBS due to its bufferless characteristic,
even more critical without wavelengths converters. So, resource
assignment is an important issue to solve in OBS networks. In
this paper, two distributed resources assignment schemes without
wavelength conversion capability are proposed. Whereas the first
one is applied at the edge nodes to achieve a loss-free core
network, the second is an enhanced routing and wavelength
assignment scheme applied at core nodes. Simulation results
indicate that the first scheme offers a loss-free solution with
blocking probability only at ingress nodes and high traffic load.
The second one reduces the network-wide burst loss probability
significantly compared with other schemes.
