The paper presents the network provisioning proposed for the Future Internet solution called System IIP. The relation of the provisioning rule to the management strategy is described. The required input parameters as well as two proposed approaches to provisioning are given. The first approach formulates an optimization problem with the goal function(More)

In this paper, a novel FSR-SP-LWC algorithm of sharing the backup lightpath capacities for WDM networks with limited wavelength conversion capability, has been proposed. The key feature is that it also provides fast service recovery for the price of only a little degradation of link capacity utilization. The ILP model has been introduced and followed by the(More)
In this paper we consider a multilayer architecture: IP-MPLS over optical transport networks (OTNs). Nodes have integrated functionality of optical cross connects (OXCs) in the optical layer and of IP routers in the IP layer. Any two IP routers can be connected together by an all-optical wavelength-division multiplexing (WDM) channel, called a lightpath.(More)
