Performance of All-Optical Networks with Limited-Range Wavelength Conversion
Previous works have shown that wavelength conversion can considerably improve the performance in all–optical networks. However, it is an unrealistic assumption under the current technology and wavelength conversion with a limited range, not a full range, is more promising. In this paper, we propose a new analytic approach for such networks by virtue of the layered–graph where each wavelength is...
متن کاملA Heuristic for Placement of Limited Range Wavelength Converters in All-Optical Networks
KR Venugopal, M Shiva Kumar, P Sreenivasa ... Computer Networks, 2001 Elsevier Wavelength routed optical networks have emerged as a technology that can effectively utilize the enormous bandwidth of the optical fiber. Wavelength converters play an important role in enhancing the fiber utilization and reducing the overall call blocking probability of the ... Cited by 80 Related articles BL Direct...
متن کاملDimensioning Wavelength-Routed Multi-Fiber WDM Networks with Limited Number of Wavelength Converters
Sparse-partial wavelength conversion in WDM networks has been shown as a very efficient network architecture. We present a network analysis and network dimensioning approach for stochastic path requests based on a reduced load approximation. This model enables us to dimension the number of WDM-systems per link and the number of wavelength converters per node needed to guarantee a maximum blocki...
متن کاملWavelength assignment scheme for WDM networks with limited-range wavelength converters
We propose a new wavelength assignment scheme that improves the blocking probability of WDM networks that use limited-range wavelength converters. Limited-range wavelength converters are attractive for wavelength-routed networks, given current technology, since they offer good utilization of the wavelength resource and improved blocking probability. However, their conversion ranges are limited;...
متن کاملPerformance Analysis of Wavelength Assignment Policies in All-Optical Networks with Limited-Range Wavelength Conversion1
Previous analytic approaches for all-optical networks have only allowed a random wavelength assignment policy in spite of the fact that network performance can be improved by other wavelength assignment policies such as first-fit wavelength assignment. In this paper, we develop an approximate analytic method to allow flexible wavelength assignment policies by virtue of a layeredgraph approach. ...
