METHOD AND APPARATUS OF MULTI-SERVICE BANDWIDTH ALLOCATION IN ETHERNET PASSIVE OPTICAL NETWORK

摘要

The present invention provides a method and apparatus of multi-service bandwidth allocation in an Ethernet Passive Optical Network (EPON) System. The System comprises the Optical Line Termination (OLT) and several Optical Network Units (ONUs) connected to the OLT, wherein, ONUs locally distinguish the types of service flows and allocate different logical link channels to each service flow based on its type, while OLT selects different bandwidth allocation methods and corresponding service scheduling for the logical link channels based on the types of service flows; ON Us perform corresponding local service scheduling based on the bandwidth allocation methods. ONUs may further identify the user group properties of the service flows, OLT and ON Us can schedule the services reasonably according to the characteristics of user groups to meet the requirements on user bandwidth or service application. As to the Multi-Dwelling Unit/Multi-Tenant Unit type of ONU, the present invention can effectively solve the limitations of application on multiple users and multiple services.
