In this paper, the authors investigate the use of two destination-initiated wavelength-weighted reservation (DW2R) protocols for the distributed setup of dynamic lightpaths in wavelength division multiplexed (WDM) rings. The two protocols are based on a weight-based wavelength selection heuristic, recently proposed for mesh topologies. The main objective of the DW2R protocols is to reduce the probability of service denial due to multiple and concurrent wavelength reservation attempts, initiated by distinct sources. A detailed performance study based on simulation experiments on ring topologies reveals for the first time a number of desirable scalable properties of the DW2R protocols.

Abstract
In this paper, the authors investigate the use of two destination-initiated wavelength-weighted reservation (DW2R) protocols for the distributed setup of dynamic lightpaths in wavelength division multiplexed (WDM) rings. The two protocols are based on a weight-based wavelength selection heuristic, recently proposed for mesh topologies. The main objective of the DW2R protocols is to reduce the probability of service denial due to multiple and concurrent wavelength reservation attempts, initiated by distinct sources. A detailed performance study based on simulation experiments on ring topologies reveals for the first time a number of desirable scalable properties of the DW2R protocols.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
