Abstract
Wavelength Division Multiplexing (WDM) is a promising technology that can construct backbone networks to comply with its exponentially increasing bandwidth requirements. An important part of this network's cost is the total length of the fiberlinks needed to create the network. A second significant cost is the bandwidth cost that reflects how efficiently the network's topology facilitates its use of bandwidth. A network model is used where nodes of the network are points on the unit square, and the costs of fiber-links between nodes are the Euclidean distances between the nodes. Fiberlink and bandwidth costs are defined with respect to this model. Two network topologies are investigated that provide both low fiber-link and bandwidth costs. These two network topologies can support survivable data rings, although their methods for routing lightpaths differ.
