Quality of service management in hybrid optical-LTE access networks

In this work we show how to manage the integration between wireless and wired networks. In particular, as wireless technology LTE (Long Term Evolution) was chosen for its characteristics of bandwidth, point-to-multipoint, nomadic and mobile characteristics. We show how to extend the wired network performances, in terms of bandwidth and QoS, to the wireless access assuming different access and backhaul configurations: point-to-point, point to multipoint (or Passive Optical Networks, PON) and Wavelength Division Multiplexing (WDM) PON. The investigation has been carried out by means of OPNET simulations. We will show how it can be ensured the QoS of specific services by working both directly in the cell LTE and in the optical network with techniques DiffServ over MPLS.
