Abstract
A frame input/output unit allows a frame to pass according to directions output by a flag judging unit while consuming resources. A resource managing unit manages amounts of resources supplied and consumed. A management information storage unit stores passing information indicating policers that have passed frames during each period and management information including flag information on skip flags and the like. A flag updating unit catalogs a resource surplus flag and a supply filled flag at the end of a previous period and a skip flag that indicates whether a self-policer skips consuming resources in the following period based on the passing information in the previous period and the current period. The flag judging unit refers to a latest skip flag and judges the presence or absence of frame passing in the following period.
