| Hypothesis: Multimedia Information with real time video will be very important and require a megabit/second bandwidth or more per client |
| The total national network bandwidth needed is minimized if server is near to the client |
| It is least expensive to install local rather national or state high speed links |
| Deduction: We have familiar "Data Locality" problem of Parallel Computing |
| Hypothesis: It is possible to define "communities" so that most material accessed by many (in particular more than one) people. |
| Data replication in hierarchical fashion is known solution with "pre-fetching", "caching" and "cache coherence" as issues |
