Wide area data services (WDS) are a superset of smaller market segments that include WAN optimization, WAFS (wide area file services), and application acceleration. Wide area data services allow the consolidation of file servers from remote sites to the data center without compromising end-user performance and also enable the acceleration of distributed applications based on file systems.
To date, wide area wireless data services have not grown nearly at the speed of their wired counterparts. Reasons include the lack of bandwidth on the wireless interface, the form factor of wireless devices and the cost of wireless services. However, emerging services and research activities are currently addressing these constraints. New standards, such as the General Packet Radio Service (GPRS) and the GSM Evolution Enhanced Data Rates (EDGE), are being developed to allow access to wireless packets at hundreds of kilobits per second and various types of new wireless and portable devices available. The remaining obstacle to the success of wireless data services is cost. One way to keep the cost of wireless data packet networks low is to reuse the infrastructure of existing packet networks and comply with accepted data network standards. This will enable integrated wireless / wired packet data networks and allow applications to operate on both types of networks. In addition, advances in packet technology can be applied directly to wireless networks. In this article, we discuss the use of the IETF Mobile IP 1 as a network protocol to provide wireless broadband packet data services. The use of Mobile IP complies with the previously established objectives of allowing reuse of the existing packet infrastructure for integrated wireless data / cabling and adherence to a widely accepted data network standard. In addition, as IP telephony and quality of service (QoS) standards are finalized and deployed, they can be applied to a mobile IP based network.
