Mobile internetworking protocols for wireless networks with ATM backbones

Protocols for the interoperable implementation of internetworking protocols (IF) and asynchronous transfer mode (ATM) address the issues of address resolution and routing of IP datagrams in an ATM environment to support stationary hosts. To provide mobile computing a protocol, called Mobile IP allows users to move around in the network and yet maintain continuous network connectivity. Mobile IP and IP over ATM protocols have been designed for commercial networks, with less stringent quality and survivability requirements than military networks. We discuss the limitations of the Mobile IP and IP over ATM protocols for tactical military network applications. We define solutions for providing mobility support to mobile IP hosts in an integrated network environment comprised of IP and ATM networks. We present a solution interworking Mobile IP and a specific IP over ATM protocol-Next Hop Resolution Protocol (NHRP) for an initial architecture with wireless access to ATM backbones
