Splittable tra c partition in WDM = SONET rings to minimize SONET
SONET ADMs are the dominant cost factor in the WDM=SONET rings. Recently several articles (Belvaux et al., European J. Oper. Res. 108 (1) (1998) 26–35; C+ alinescu and Wan, Tra c partition in WDM=SONET rings to minimize SONET ADMs, submitted for publication; Gerstel et al., Proc. IEEE INFOCOM’98, vol. 1, pp. 94–101; Liu et al., Proc. INFOCOM, vol. 2, 2000, pp. 1020–1025; Sutter et al., Oper. Re...
متن کاملA Wavelength Assignment Heuristic to Minimize SONET ADMs in WDM Rings
Optical Wavelength Division Multiplexing (WDM) rings are being deployed to support multiple SONET/SDH selfhealing rings over a single physical optical ring. In such systems, the dominating cost is the SONET Add/Drop Multiplexers (ADMs). To minimize the system cost, algorithms must be developed to assign wavelengths to lightpaths in the system so that the number of ADMs required is minimized. Ho...
متن کاملWavelength Assignment to Minimize the Number of SONET ADMs in WDM Rings
Optical Wavelength Division Multiplexing (WDM) rings are being deployed to support SONET/SDH self-healing rings. The cost of such a system is dominated by the SONET Add/Drop Multiplexers (ADMs). To minimize the system cost, algorithms must be developed to assign wavelengths to lightpaths in the system so that the number of ADMs required is minimized. This problem of optimal wavelength assignmen...
متن کاملBetter Bounds for Minimizing SONET ADMs
SONET add-drop multiplexers (ADMs) are the dominant cost factor in SONET /WDM rings. The number of SONET ADMs required by a set of traffic streams is determined by the routing and wavelength assignment of the traffic streams. Following previous work, we consider the problem where the route of each traffic stream is given as input, and we need to assign wavelengths so as to minimize the total nu...
متن کاملSelect Line Speeds for Single-Hub SONET/WDM Ring Networks
Minimizing SONET ADM costs in single-hub SONET/WDM ring networks via traffic grooming has been discussed in a number of recent works. Recent work [12] gives the exact minimum costs of uniform traffic in both UPSR and BLSR/2 and proves that the BLSR/2 would never be more expensive than UPSR under any traffic pattern, if all wavelengths have same capacity. In this paper we consider how to groom b...
