—One of the main challenges for the future of information and communication technologies is the reduction of the power consumption in telecommunication networks. The key consumers are the home gateways at the customer premises for fixed line access technologies and the base stations for wireless access technologies. However, with increasing bit rates, the(More)
Information and Communication Technology (ICT) devices and services are becoming more and more widespread in all aspects of human life. Following an increased worldwide focus on the environmental impacts of energy consumption in general, there is also a growing attention to the electricity consumption associated with ICT equipment. In this paper we assess(More)

— We propose a dynamic bandwidth allocation (DBA) algorithm for Ethernet passive optical networks (EPON). The DBA algorithm exploits the sleep mode functionality, where the optical network unit (ONU) at the user premises is put to sleep in every cycle according to the traffic load of the ONU. The DBA algorithm achieves up to 93% power savings in comparison(More)
— This paper describes extensive research in the field of the Multipoint Control Protocol (MPCP) for the Ethernet Passive Optical Network (EPON). More in particular the dynamic bandwidth allocation (DBA) algorithm IPACT (Interleaved Polling with Adaptive Cycle Time) is analytically modeled. The main focus has been on analyzing cycle times and packet delay(More)
Access networks must further advance to address the intensification of the requirements of growing speeds and the usage of Internet applications, and time and wavelength division multiple access (TDMA/WDMA) based passive optical networks (TWDM-PONs) have been widely considered as one of the evolutionary steps of next-generation optical access (NGOA)(More)
