Communication device, address learning method, and program

Abstract

An object of the present disclosure is to reduce band compression even in a case where a frame addressed to an original (overwritten) MAC is received again after a MAC address is overwritten. A communication device according to the present disclosure measures a traffic amount in any predetermined determination data unit, holds MAC entry information including the measured traffic amount and a MAC address in a MAC learning data holding unit, at the time when the number of pieces of MAC entry information held by the MAC learning data holding unit reaches an upper limit, searches for minimum MAC entry information with a minimum traffic amount from among traffic data amounts in determination data unit held by the MAC learning data holding unit, and overwrites the minimum MAC entry information obtained by search with unlearned MAC entry information that is not held by the MAC learning data holding unit.

Dependencies are inferred from the claim text.
