Hybrid Dynamic Bandwidth and Wavelength Allocation Algorithm to Support Multi-Service Level Profiles in a WDM-EPON
A novel bandwidth assignment algorithm in WDM Ethernet Passive Optical Networks, called DyWaS-SLA, is proposed not only to provide service differentiation but also to offer subscriber differentiation. Simulation results show that DyWaS-SLA outperforms other bandwidth allocation algorithms in WDM-EPONs as it makes fairer bandwidth distribution than those methods. Consequently, it always insures ...
متن کاملFractional Optimal Golomb Ruler Based WDM Channel Allocation
A novel channel allocation method, based on optimal golomb ruler, that allows reduction of FWM effect while maintaining bandwidth efficiency, is presented. Simulation is carried out to show performance improvement in WDM systems without inducing bandwidth increase.
متن کاملWDM Dynamic Bandwidth Allocation Schemes for Ethernet PONs
WDM based dynamic bandwidth allocation schemes are proposed as potential future-proof upgrade solutions for access PON systems. The schemes represent cost-efficient ways to exploit the virtually unlimited bandwidth afforded by passive optical architectures whilst remaining fully compatible with the IEEE Ethernet standard for the first mile (EFM 802.3ah).
متن کاملNew and Improved approaches for Dynamic Bandwidth and Wavelength allocation in LR WDM/TDM PON
Dynamic Bandwidth Allocation is a major open research challenge in the migration of Passive Optical Network (PON) systems towards Long Reach PON, especially when hybrid WDM/TDM is used (LR WDM/TDM PON). New and efficient solutions for Dynamic Bandwidth and Wavelength Assignment are sought to address two main critical issues of such PON systems: how to schedule the transmissions over multiple wa...
متن کاملChannel allocation algorithm for WDM systems.
An algorithm for WDM channel allocation, based on the concept of Optimal Golomb Ruler (OGR), is proposed. This algorithm enhances system performance by locating an allocation set, where the degradation caused by the effects of interchannel interference and Four-Wave Mixing (FWM) is minimal. Two sets of simulation were performed on an 8x10Gbpschannel system (channel spacing of 50GHz for equally ...
متن کامل(WDMA) to support multiple wavelengths in either or both upstream and downstream directions [2]. For employing the WDMA technology, the passive arrayed waveguide grating
This study proposes a novel fault-tolerant architecture in WDM-EPON, Cost-based Fault-tolerant WDM-EPON (CFT-WDM-EPON), to provide overall protection. The CFT-WDM-EPON only equips a backup feeder fiber to recover the system failure. Additionally, a prediction-based fair wavelength and bandwidth allocation (PFWBA) scheme is also proposed to enhance the differentiated services for WDM-EPON based ...
