  • Wide area network (WAN) interface for a transmission control protocol/internet protocol (TCP/IP) in a local area network (LAN)
    Patent number: 5802285
    Abstract: The invention relates to a method for interfacing a transmission control protocol/internet protocol (TCP/IP) area network (LAN) to a wide are network via a MAC manager. The TCP/IP software uses a lower-level address resolution protocol (ARP) protocol to find physical network addresses corresponding to logical internet protocol (IP) addresses, and a lower-level IP protocol to transfer useful traffic in IP data packets. In the invention, the media access control (MAC) manager of the wide area network (3) simulates operation complying with the ARP protocol towards the TCP/IP software, and transmits and receives only IP data packets over the wide area network (3) in a manner specific to the wide area network.
