Assume a Full-Service STOLAS network with aggregated traffic inputs. Create a realistic traffic input scenario for this network that may be representative of a typical European region in year 2009. Realistic traffic input created using three generic sources: Voice (Poisson), Data (Pareto), Video (Gamma).

• GigaPON is based on passive optical technology (1.25 GBit/s symmetrical) ; it can be seen as an upgrade for a BPON which is standardised up to 622 Mbit/s.
• The system will be packet oriented with a mixture of real-time and non-real time data in an IP dominated world. A GigaPON system that combines high transmission efficiency with a guaranteed level of QoS clearly represents a competitive opportunity.
• The main technical issues are found in the upstream link, from the user side (ONU) to the network side (LT).

•A management architecture for flow based IP services across core, and multiple access domains has been developed and tested for different QoS.•A novel time-and-wavelength MAC protocol for packet-based access networks has been designed. An implementation in an emulator for real data traffic will be used for the field trial.
