Method for dynamic allocation of bandwidth in passive optical networks with traffic prediction

摘要

Summary method for dynamic allocation of bandwidth in passive optical networks with traffic prediction.The present invention relates to a method in which the OLT uses prediction of traffic load carried by a TDNN (time delay neural network, neural network with time delay) in the DBA (dynamic bandwidth assignment, dynamic band allocation), allowing to estimate and predict the demand fut URA traffic (band), based on the history of upstream traffic of each ONU.The said method of DBA performs the inference of traffic load in the UN based preferably on TM method and comprises the following steps: DBA prediction (701) of the demand of traffic RIL of each alloc ID I through the TDNN; assigning a fixed band (702) RIF for each alloc ID I; Atri Distribution of band ensured (703) for each alloc ID I until a level is supplied at AlcanUnder cover or the travel demand is satisfied; the allocation of the band extra (704) for all alloc IDS in proportion to the demands of traffic remaining up to the limit of their respective maximum levels set kidney; generating as a result of the information required for assembly of the Map of bandwidth (bwmap) to be sent to the onus. 1 / 1
