Traffic grooming refers to techniques used to combine low-speed traffic streams onto high-
speed wavelengths in order to minimize the networkwide cost in terms of line terminating …

We consider the problem of designing a virtual topology to minimize electronic routing, that
is, grooming traffic, in wavelength routed optical rings. The full virtual topology design …

Summary form only given. We consider an arbitrary-topology, optical mesh network which
employs wavelength-division multiplexing (WDM) to multiply the bandwidth on its links. Our …

We employ a new, generic graph model for dynamic traffic grooming in WDM mesh
networks. The novelty of this model is that, by only manipulating the edges of an auxiliary …

We consider the problem of traffic grooming in wavelength-division-multiplexing (WDM)
rings. Our objective is to minimize the required number of electronic add–drop multiplexers …

Publisher Summary The long-haul domain is extensively used for lightwave systems as the
cost of expensive hardware can be shared among many users. Nowadays, because the …

We consider the problem of traffic grooming in wavelength-division-multiplexing rings with
all-to-all uniform traffic. Our objective is to minimize the total number of electronic add-drop …

In a WDM optical network, the bandwidth requirement of a customer's connection can vary
over a wide range, and many of these connections could have a capacity that is much lower …

This work focuses on developing and implementing comprehensive unified constraint-based
routing algorithms within the generalized multi-protocol label switching framework (GMPLS) …

This paper studies the design of low-cost survivable wavelength-division-multiplexing
(WDM) networks. To achieve survivability, lightpaths are arranged as a set of rings …
