Abstract:
The invention provides a method and system for Dynamic Bandwidth Assignment (DBA) Virtualization in a Passive Optical Network, comprising an Optical Line Termination (OLT) point and a plurality of Optical Network Units (ONU) and a plurality of Virtual Network Units (VNO), wherein each VNO is configured with a virtual Dynamic Bandwidth Assignment module to schedule a bandwidth assignment independently of the other VNOs and using a merging engine to implement a detailed bandwidth scheduling allocation over the Passive Optical Network.
