Wavelength Division Multiplexing (WDM) optical networks with traffic grooming routes and consolidates sub-wavelength connections onto light paths, to improve network usage and to reduce its cost. It can be classified into dynamic or static depending on its connections that are given in advance or randomly arrive in/depart out. In this paper, an analytical model is developed for dynamic traffic grooming, allowing asymmetric data rates for sub-wavelength connections, arbitrary alternate routing in both physical and dynamic topologies, and arbitrary wavelength conversion.
