Shared-Wavelength WDM-PON Access Network --- Bursty Traffic Accommodation and User-defined SLA Support

We investigate the shared-wavelength WDM-PON architecture which accommodates bursty downstream traffic. Based on the architecture, the proposed flow-scheduling algorithm can support user-specified service level agreements (SLAs), especially under high traffic load. Illustrative results demonstrate that the new architecture can provide a user with a number of streaming flows with bandwidth and maximum delay guarantees, as well as average bandwidth guarantee for data flows, as specified by the user-defined SLA.
