Abstract

An OLT connected with a controller managing slices includes a bandwidth allocating unit capable of allocating bandwidths in a PON system to ONUs through allocation methods, a slice managing unit that calculates a guaranteed delay time for each allocation method, receives, from the controller, a resource reservation request including a bandwidth requested to be reserved in the PON system for a slice and a requested delay time, and determines an allocation method associated with the request based on the requested delay time and the guaranteed delay time for each allocation method, and a resource information generating unit that holds, as abstract resource information, an available bandwidth for the guaranteed delay times of each ONUs, calculates an available bandwidth in the allocation method of the associated ONU based on the allocation method associated with the request and the requested bandwidth, and updates and transmits the abstract resource information, to the controller.
