A network environment capable of performing a smooth and comfortable TCP session operation is provided to a user. The session relay equipment includes a bridge portion which relays a session by which a sequence of packets are transmitted and received between terminals connected with each other via a network; a socket information table which has socket information containing (1) address information of the terminal and (2) protocol information used in the session, the socket information being associated with information on whether or not the session is to be terminated; and a service information table which has information on a communication service to be provided for each service provision unit, the communication service being identified based on predetermined information within a header of the packet. The bridge portion terminates the session and executes a communication service based on the information contained in the header of the packet and the socket information.
