<p><P>PROBLEM TO BE SOLVED: To provide a packet update apparatus capable of flexibly revising contents of packet update processing and supporting versatile protocols and packet forms so as to sophisticate the packet update processing. <P>SOLUTION: An update information table T3 is used for managing packet update information obtained by a protocol processing section 12. An update processing contents determining table T4 that can optionally be revised and set from a host device is used to manage packet update processing contents corresponding to an update code C2. An update processing section 14 searches the update processing contents determining table T4 by using the update code C2 for a key to determine the update processing contents of a received packet, searches the update information table T3 by using a packet identification code C1 for a key to read packet update information on the basis of the determined update processing contents thereby carrying out update processing of the received packet, and directly carries out the update processing on the basis of the update processing contents determined by the update code C2 when the update processing section 14 desires to revise the update contents of the packet update information. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
