    Cost-efficient fiber connection topology design for metropolitan area WDM networks by Guan, Kyle C., Chan, Vincent W. S.

    Published 2012
    “…In this paper, we provide some analytical insights into physical architectures that can serve as benchmarks for designing a cost-efficient WDM metropolitan area network (MAN). For uniform all-to-all traffic and regular topologies with nodal symmetry, we identify a class of regular graphs--Generalized Moore Graphs--that have several attractive properties by formulating a first-order cost model and characterizing the tradeoff between fiber and switching resources. …”
