Hop and Bandwidth Integrated Routing For Optical Ethernet Networks Under Constraints of Dispersion Effects

The routing of wavelength channels with maximum chance of non-blocking and error free due to residual dispersion, and efficient allocations of bandwidth networks are essential, especially in ultra-high speed optical at which the impairments due to linear and nonlinear dispersion effects are detrimental and must be taken into account in the routing and interconnecting the propagation routes. In this paper we propose a routing algorithm that integrates the network layers of the networks, the physical trans-mission layer, the network wavelength channel management and the routers for connecting and routing of wavelength channels over physical lightpaths which are under constraints of wavelength availability, capacity of the lightpath and the dispersion effects over hops and impairments due to dispersion effects. The Hop and Bandwidth Integrated Routing (HBIR) is proposed for routing of lightpaths in the peer model of IP over WDM networks. Traffic performance is evaluated of some typical all-optical metro-networks.
