<p>PROBLEM TO BE SOLVED: To enable security control and priority transfer control corresponding to a session by giving a subsequent packet belonging to the same session to the bypass path of a main processing part based on the packet information. SOLUTION: When a received packet (S1) is managed as a session (S2), the packet is directly transferred to a switching part and a packet scheduling processing part (S7) without performing routing processing (S3), filtering processing (S4) nor priority control processing (S5), is transmitted (S8) and transferred without performing redundant processing. Information (packet information) for identifying a specified packet is defined by detecting the session in this way, the hardware part of a packet transferring device processes security control and priority transfer control to be executed based on the definition information while cooperating with a main processing part, and about a packet capable of being analogized from a previously arriving packet, the packet is transmitted by bypassing the main processing part.</p> |
