Abstract
A TCP 2003 is terminated in an intermediate driver 2006 within a gateway device 20, a TCP 3003 is terminated in an intermediate driver 3006 within a gateway device 30, and a frame is transferred between the intermediate drivers with a method not causing a congestion control such as a UDP. Besides, an SSL session is constructed between an SSL 2002 and an SSL 3002, and upon completing construction of the session, a public key and a secret key are sent by means of an Ethernet frame from a processing speed acceleration engine control to a processing speed acceleration engine. Thus, the gateway device transfers the frame not through a CPU but by employing the processing speed acceleration engine within an NIC in later communication between a terminal 21 and a server 31.
