摘要

Energy-efficiency and green communications have become dominant topics related to access network implementation, since their energy consumption is a major contributor of energy consumption within the Internet. In this paper we analyze an implementation of anew energy-efficient dynamic bandwidth algorithm in afour-channel Wavelength Division Multiplexing Ethernet Passive Optical Network(WDM EPON), in which wavelength assignments take place per service class and not per Optical Network Unit(ONU). The improved Dynamic Bandwidth Allocation (DBA) algorithm introduces independent bandwidth allocation for each wavelength, which results in efficient bandwidth management and utilization. The mathematical model for new DBA algorithm is described, as are changes to the Multi-Point Control Protocol(MPCP), necessary for its implementation. The obtained results show thatthe redefined DBA algorithm improves Key Performance Indicators(KPIs) and as a consequently enables delivery of enhanced services to end-users. Significant energy savings are achieved without Quality of Service (QoS) degradation, and without network or equipment architecture changes.
