A Review of Routing and Wavelength Assignment Approaches for Wavelength- Routed Optical WDM Networks
TL;DR: In this paper, a distributed relative capacity loss (DRCL) scheme is proposed for wavelength-routed optical WDM networks, which works well in distributed controlled networks and demonstrates the performance of DRCL through simulation.

Blocking probabilities in large circuit-switched networks
TL;DR: It is shown that when the capacity of links and the offered traffic are increased together, a limiting regime emerges in which loss probabilities are as if links block independently, with blocking probabilities given by the solution of a simple convex programming problem.
