TRANSMITTER AND METHOD OF ARP COMMUNICATION VERIFYING VALIDITY CHECK AND SYSTEM OF ARP COMMUNICATION VERIFYING VALIDITY CHECK USING THE SAME

摘要

The present invention relates to an address resolution protocol (ARP) communication method and a transmitter capable of checking the validity and an ARP communication system capable of checking the validity using the same. The present invention can add a specific algorithm, agreed in a transmission end and a receipt end, to a region not used in operation codes in an ARP communication, and can check whether a response with respect to a MAC address request is effective. The ARP communication transmitter capable of checking the validity according to the present invention, in transmitting the MAC address request data of a receiver capable of checking the validity in the ARP communication, comprises: a valid region setting part for using all or a part of a region not used among operation codes to check the validity; and a request data transmitter for adding the specific algorithm, agreed with the receiver, to the validity check region and transmitting the MAC address request data to the receiver.
