Adapting to Network and Client Variation Using Active Proxies: Lessons and Perspectives Armando Fox Steven D. Gribble Yatin Chawathe Eric A. Brewer 1.1 Heterogeneity Thin Clients and luding 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. Although we expect clients to improve over time, there will always be older systems still in use that represent relatively obsolete clients, and the high end will advance roughly in parallel with the low end, effectively maintaining a gap between the two: there will always be a large difference between the very best laptop and t The Pennsylvania State University CiteSeerX Archives 2009-04-12 2007-11-22 1998 application/postscript text http://citeseerx.ist.psu.edu/citeseerx/viewdoc/summary?doi=10.1.1.42.2177 http://www.cs.berkeley.edu/~yatin/papers/adaptation.ps.gz en 10.1.1.38.1298 10.1.1.12.448 10.1.1.112.9002 10.1.1.21.1584 10.1.1.145.8046 10.1.1.1.2034 10.1.1.32.6145 10.1.1.37.8716 10.1.1.132.6511 10.1.1.112.6464 10.1.1.41.6760 10.1.1.32.7346 10.1.1.41.4993 10.1.1.41.4031 10.1.1.35.8868 10.1.1.39.8564 Metadata may be used without restrictions as long as the oai identifier remains attached to it.
