  • Relay device, packet filtering method, and packet filtering program
    Patent number: 7633957
    Abstract: A relay device 10 is a relay device for relaying a communication message on a packet-by-packet basis, which comprises an order determiner 13 for determining whether a packet received is one received in an order to be received, a packet holder 14 for, when it is determined that the packet is not one received in the order to be received, holding the packet, and for performing such a control as to relay the packet, a merger 15 for merging a payload of the received packet with a payload of the held packet, a verifier 16 for verifying whether a payload of a packet satisfies a predetermined rule, and a relay controller 17 for, when a packet satisfies the rule, performing such a control as to execute relay of the packet. This prevents an increase of a communication delay and enables detection of an irregular communication message in an application layer protocol, irrespective of types of protocols.
