A heuristic for placement of limited range wavelength converters in all-optical networks
TL;DR: Investigation of heuristics for placing limited range wavelength converters in arbitrary mesh wavelength routed optical networks finds that limited range converters at a few nodes can provide almost the entire improvement in the blocking probability as the full range wavelengths placed at all the nodes.

Dynamic routing and resource allocation in WDM transport network
TL;DR: The way non-Poisson traffic behaviour affects performance of routing strategies is investigated and how the results from dynamic routing investigation can help to optimise the network planning process is presented.

Lightpath communications: an approach to high bandwidth optical WAN's
TL;DR: It is shown that although the problem of optimally establishing lightpaths is NP-complete, simple heuristics provide near optimal substitutes for several of the basic problems motivated by a lightpath-based architecture.

Routing and wavelength assignment in all-optical networks
TL;DR: The authors derive an upper bound on the carried traffic of connections for any routing and wavelength assignment (RWA) algorithm in a reconfigurable optical network and quantifies the amount of wavelength reuse achievable in large networks as a function of the number of wavelengths, number of edges, and number of nodes for randomly constructed networks as well as de Bruijn networks.
