Abstract
The access network infrastructure plays an important role in the overall
performance of the network, next generation access networks (NGA) must be able to
access diverse services, and should incorporate adequate architectures that include
mechanisms for the integration of different technologies. New optical access
technologies trends are: WDM, 10 Gb/s, and longer reach/higher splits. It is also
important to take into account the evolution of the installed legacy PONs to the next
generation optical access networks. The present paper goes through such topics,
focusing on the research being carried out to develop dynamic bandwidth algorithms for
the 10 Gb/s new EPON standard (IEEE 802.3av). We summarize results and point out
issues that will require further investigation
