<p>A transmission information transfer apparatus for realizing the MAC VLAN function with low latency includes: a VLAN table memory (114) that manages a VID and a VLAN membership; a VLAN cache (115) which is a cache memory that manages a VLAN Cache Index and VLAN membership in association with one another; an FDB (112) that manages the VID, DA, and output port information in association with one another and further manages the VID, SA, and VLAN Cache Index in association with one another; an extraction section that extracts the VID, DA, and SA included in an input packet; an FDB search section (111) that acquires output port information associated with the VID and DA, as well as the VLAN Cache Index associated with the VID and SA; a table controller (113) that acquires the VLAN membership associated with the VLAN Cache Index; and an output port determination section (116) that determines an output port of a packet.</p> |
