Abstract

many axes, including screen size, color depth, effective bandwidth, processing power, and ability to handle specific data encodings, e.g., GIF, PostScript, or MPEG. As shown in tables 1 and 2, each type of variation often spans orders of magnitude. High-volume devices such as smart phones [12] and smart two-way pagers will soon constitute an increasing fraction of Internet clients, making the variation even more pronounced. These conditions make it difficult for servers to provide a level of service that is appropriate for every client. Application-level adaptation is required to provide a meaningful Internet experience across the range of client capabilities. Despite continuing improvements in client computing power and connectivity, we expect the high end to advance roughly in parallel with the low end, effectively maintaining a gap between the two and therefore the need for application-level adaptation.
