Abstract

Abstract In the last decade, the bit rates achieved on fiber broadband networks have increased multiple times and every new generation of passive optical network (PON) technologies must unlock more of fiber’s potential and must be backward compatible to ensure easy and iterative upgrade of operator’s networks. In this paper we present two novel dynamic wavelength (in the case of multichannel system) and bandwidth allocation models for realization of fully QoS (Quality of Service)-aware single-channel i.e. multichannel Ethernet passive optical network (EPON). The both presented models include a novel approach for inter/intra –ONU (Optical Network Unit) scheduling mechanism as well as advanced support for multimedia and business-related services. Moreover, the single channel system could be upgraded to multichannel system on per-need basis i.e., only nodes with higher traffic demands could be upgraded. The aim of this approach is twofold. On the one side we hope to avoid the implementation of additional, complex algorithms usually related to QoS support in the access segment and on the other side to develop a solution in which new and old EPON technologies are able to coexist. This approach would eliminate the need for complex migrations, complicated and time consuming procedures as well as possible service outages in the access network. We present detailed simulation experiments with the aim of conducting a study of the performances of both presented approaches and validate both of them in the terms of the future application, further service development and implementation in the next generation broadband networks (NGNs).
