Existing Approaches

Provide multiple versions of content, e.g. Xinside
  • Increased administration at server
  • Changes to server code, to support e.g. Odyssey [Satyanarayanan et al. ]
  • Difficult and getting worse, since "anyone" can be a server
Progressive encodings
Use ALT text
  • WWW is already graphics-intensive
  • Advertising is making "logo visibility" important
Caching and prefetching
  • Reduces latency but not bandwidth to client
  • Caching is necessary, but orthogonal to our approach
