Abstract
A technique for transferring information in a passive optical network is disclosed. The technique may be realized as a method for transferring information in a passive optical network having a plurality of network nodes. The method comprises transmitting a downstream signal during a control/management time slot of a periodic frame having N control/management time slots and M data time slots, wherein the downstream signal includes an identifier of a service node in the network, wherein each of the N control/management time slots corresponds to a respective one of N possible service nodes in the network. The method also comprises responding to the downstream signal with an upstream signal during the control/management time slot of the periodic frame. The method further comprises allocating at least one of the M data time slots of the periodic frame to the service node based at least in part upon the upstream signal.
