摘要： In general, techniques are described for monitoring downstream traffic in order to schedule delivery of upstream traffic in a computer network. The techniques may be implemented by an optical line terminal (OLT) comprising a control unit and an interface. The control unit determines an amount of upstream data that is waiting at one of a plurality of ONTs to be transmitted upstream to the OLT, and determines an amount of downstream data that is transmitted by the OLT to this ONT. The control unit increases the determined amount of upstream data based on the determined amount of downstream data transmitted by the OLT to the ONTs and, after increasing the determined amount of upstream data, generates an upstream grant map that grants time slots to the ONTs based on the determined amount of upstream data. The interface transmits the upstream grant map downstream to the ONTs.

摘要： In general, techniques are described for performing grant scheduling in optical networks. An optical line terminal (OLT) comprising a control unit may implement the techniques. The control unit determines an amount of upstream data associated with a category of service that is waiting at a first one of a plurality of ONTs to be transmitted upstream to the OLT and computes a number of GCPs for each of the ONTs based on a determined amount of data associated with the category of service that is waiting to be transmitted upstream to the OLT for each of the ONTs. After computing the number of GCPs, the control unit then grants time slots to the one or more of the ONTs based on the number of GCPs computed for each of the ONTs, wherein the time slots comprise time slots for upstream communication form the ONTs to the OLT.
