Abstract
Recently, exible grid transport has gained a lot of attentions due to its higher spectral and energy efficiencies in handling dynamic diverse granularity traffic. In this paper, we introduce exible grid transport architecture and address the dynamic routing, wavelength assignment, and spectrum allocation problem. We develop a novel homogeneous irreducible Markovian model to estimate the blocking of point-to-point connections and an analytical model using the reduced load approximation technique to estimate the blocking of multi-hop connections. The numerical results show that the proposed models provide reasonable estimation of blocking for connections with lower state-space complexity and quicker convergence time.
