- Seamless integration of an organization’s mobile and fixed networking infrastructures.
- Optimal utilization of scarce resources such as the bandwidth of low-capacity satellite links.
- A robust connectivity service that eliminates the impact of mobility on new and existing connections as long as connectivity exists.
IBM’s support for mobile ATM networks is described in detail in a companion White Paper, "IBM Mobile ATM Networking Technology Overview" [1]. The reader should be familiar with this document. In addition, IBM’s suggested ATM architecture and addressing scheme are described in the White Paper entitled "IBM Mobile ATM Networking Network Design and Addressing Considerations" [2].
After providing a brief overview of the Mobile ATM network components and topology, this paper introduces IBM’s solution for efficiently using IP over mobile ATM and discusses alternatives for providing quality of services at the IP layer in a mobile environment.
IBM’s Mobile IP/ATM Networking solution is applicable in both commercial and military environments, and therefore the examples presented in this paper are intentionally generic.
