PROBLEM TO BE SOLVED: To apply processing, regarding various additional functions, to an IP packet while improving the performance and reducing the load. SOLUTION: In a routing module 2, first transmission route information is obtained by retrieving a route information table from a reception packet from a low-order bus transmitting/receiving section 19, a route retrieval section 17 stores the obtained information in an identifier; a packet detection section 21 retrieves a detection condition table 22, corresponding to the predetermined retrieval conditions for obtaining second transmission route information containing a module number of a function extension module 6 for applying additional function processing to the reception packet; and a route information rewriting section 20 rewrites the first transmission route information in the identifier into the second transmission route information. In the function extension module 6, a reception packet is transferred from a higher-order bus transmitting/receiving section 9, a distribution section 8 transfers the reception packet to a function execution module 7, additional processing is applied therein, and a re-routing processing section 27 determines a transmission route of the packet after processing.
