dynamic bandwidth allocation method (dba); dynamic bandwidth allocation device (dba); and xg pon system

摘要

summary dynamic bandwidth allocation method (dba); dynamic bandwidth allocation device (dba); and system xg pon a dba method is disclosed, including the acquisition of an upstream data size and a dynamic bandwidth report (dbru) of a current transmission container (tcont) which estimates a width estimate value of current tont band; performing a bandwidth allocation calculation according to the current tcont bandwidth estimate value and pre-configured service layer agreement (sla) information to obtain a bandwidth allocation value from the tcont current. a dba device and xg pon system are disclosed which can, taking into account the negative return adaptive compensation during band allocation, accurately allocate bandwidth for different tconts in case of different overload, thus avoiding lower such as a binding error or a statistical error and ensuring adaptive bandwidth compensation by implementing accurate bandwidth allocation, thus avoiding packet loss caused by insufficient bandwidth allocation and waste caused by excessive allocation of bandwidth.
