Abstract

In this paper, we tackle the problem of resource allocation in Time-Domain Wavelength Interleaved Network (TWIN), which is an optical burst switching solution for metropolitan optical networks. We propose two ways of improving the slot allocation efficiency in such networks: by minimizing the schedule length and by enforcing a cyclical QoS constraint on the allocated slots. We report the detailed simulation results on how network topology, traffic pattern and the proposed QoS improving method impact the network performance.
