Abstract

In this paper, a bidimensional Quality of Service (QoS) differentiation framework, which considers both the physical layer impairments (PLIs) and the set-up delay as well as the impact of the former on the latter, is proposed to implement service differentiation in transparent optical networks. In addition, a new PLI-aware routing and wavelength assignment (RWA) algorithm based on the proposed framework is designed and simulation results show that the proposed algorithm can reduce the blocking probability (BP) of the network, guarantee the quality of transmission (QoT), and low set-up delay for multiservice offerings.
