Effective traffic grooming in WDM rings
Much work has focused on traffic grooming in WDM ring networks. Previous work has considered many aspects of traffic grooming, including minimizing number of ADMs, minimizing number of wavelengths, single hub and multiple hub architectures, switching capabilities etc. In this work, we derive general and tighter bounds on the number of wavelengths in WDM ring networks that may be capable of swit...
متن کاملTraffic Grooming for WDM Rings with Dynamic Traffic
We study the problem of traffic grooming in wavelength-division-multiplexing (WDM) rings with dynamic traffic. We consider both unidirectional and bi-directional rings. In our dynamic traffic model, traffic is represented by a set of different traffic requirements that the network needs to satisfy, but at different times. Our objective is to minimize the required number of electronic add/drop m...
متن کاملGrooming of Arbitrary Traffic in SONET / WDM Rings
SONET add-drop multiplexers (ADMs) are the dominant cost in SONET/WDM rings. They can potentially be reduced by optical bypass via wavelength adddrop multiplexers (WADMs) and trafflc grooming. While many works have been done o n the grooming of all-to-all uniform trafflc and one-to-all trafflc, the grooming of arbitrary t r a c have not been studied yet. In this paper we first proves the NP-har...
متن کاملGraph theory and traffic grooming in WDM rings
This paper has a double purpose. In the first part of the paper we give an overview of different aspects of graph theory which can be applied in communication engineering, not trying to present immediate results to be applied neither a complete survey of results, but to give a flavor of how graph theory can help research in optical networks. The second part of this paper is a detailed example o...
متن کاملCost E ective Tra c Grooming in WDM Rings
We provide network designs for optical wavelength division multiplexed (OWDM) rings that minimize overall network cost, rather than just the number of wavelengths needed. The network cost includes the cost of the transceivers required at the nodes as well as the number of wavelengths. The transceiver cost includes the cost of terminating equipment as well as higher-layer electronic processing e...
