Summary

This is an overview of the decisions made in the previous sections of this chapter:
  1. Only shared files and applications are supported.
  2. Assumptions made regarding file usage:
  3. Session semantics were chosen for file sharing.
  4. Granularity of replication is whole files, a sensible choice in light of the above assumptions.
  5. A replica control strategy based on a primary copy scheme:
  6. The file system should require minimal changes to existing applications.
  7. The clients are assumed to be synchronized with the server, but a simple service to check this, based on Cristian's algorithm, will be provided.
  8. Caching is done in a simple least-recently-used (LRU) fashion.
