Abstract
An apparatus comprising a receiver configured to receive a plurality of transmission requests from a plurality of end nodes via an optical network and an electrical network, a processor coupled to the receiver and configured to dynamically allocate optical transmission time slots to the end nodes according to measured RTTs of the end nodes, and a transmitter coupled to the processor and configured to transmit the allocated transmission time slots to the end nodes. Also disclosed is a method performed by an OLT comprising receiving a plurality of transmission requests from a plurality of network units via a PON and an electrical network, and allocating optical transmission time slots to the network units dynamically according to measured RTTs of the network units.
