Abstract
An address resolution protocol (ARP) processing method for Ethernet matching is provided in which a message authentication code (MAC) request message including IP information is received from another application module and provides a MAC corresponding to the MAC request message, the method including: determining whether a MAC matching the IP information included in the MAC request message is stored; determining whether the MAC request message includes Ethernet over synchronous optical network/synchronous digital hierarchy (SONET/SDH) (EoS) channel information; if it is determined that the MAC request message does not include EoS channel information, detecting EoS channel information that is previously stored and that matches the IP information; and broadcasting an ARP request message to an external host via an EoS channel. The ARP processing method is performed using the EoS channel, thereby reducing unnecessary broadcast traffic packets.
