Energy Efficient Dynamic Wavelength and Bandwidth Allocation for TWDM PON
This paper proposes a new dynamic bandwidth and bandwidth allocation (DWBA) algorithm for energy saving in time and wavelength division multiplexing passive optical networks (TWDM PONs). Decreasing the number of active upstream wavelengths, the proposed algorithm not only saves power but also provides good efficiency for TWDM PON systems. Using simulations, we evaluate performance of the propos...
متن کاملDynamic Wavelength and Bandwidth Allocation with QoS for TWDM PON
We propose a dynamic wavelength and bandwidth allocation algorithm with QoS (quality-ofservice) for a TWDM PON (time and wavelength division multiplexing passive optical network) system of NG-PON2 (next generation PON stage 2). Unlike other existing methods, the proposed method supports multiple service classes and is compliant to the NG-PON2 recommendation. To increase the wavelength allocatio...
متن کاملDynamic Wavelength and Bandwidth Allocation for Power Saving in TWDM PON
This paper proposes a dynamic bandwidth and bandwidth allocation (DWBA) algorithm for time and wavelength division multiplexing passive optical networks (TWDM PONs). The proposed algorithm saves power by decreasing the number of active wavelengths of a TWDM PON system.
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 کاملPipelined Dynamic Bandwidth Allocation for Power Saving in XG-PON
This paper proposes a pipelined dynamic bandwidth allocation (DBA) scheme for 10-gigabit-capable passive optical networks (XG-PONs). The proposed scheme performs a DBA operation in multiple stages to save power. Also, requests are forwarded to next stages to obtain high performance.
