What hardware is needed for frame relay?

In computer networking, the Address Resolution Protocol (ARP) is the method for finding a host's hardware address when only its network layer address is known. Due to the overwhelming prevalence of IPv4 and Ethernet, ARP is primarily used to translate IP addresses to Ethernet MAC addresses. It is also used for IP over other LAN technologies, such as Token Ring, FDDI, or IEEE 802.11, and for IP over ATM.
