<p><P>PROBLEM TO BE SOLVED: To provide a network node for which it is highly possible to recover from an abnormal state in a short time, and a network node program. <P>SOLUTION: When a frame is received, an FDB control unit 460 retrieves an FDB 470 and selects an output port corresponding to a destination MAC address of the received frame. In the case where a registration time of an entry corresponding to the selected output port is after an FDB flash request time of an FDB flush management table 490, the FDB control unit 460 sets a field indicating presence/absence of corresponding entry reference in an FDB entry management table 480 and a switch unit 420 performs unicast transmission. In the case where the registration time is not after the FDB flash request time, the FDB control unit 460 sets an aging time and clears the field indicating the presence/absence of corresponding entry reference, and the switch unit 420 performs broadcast transmission. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
