Foil 6 Event Broadcasting: Criticism

From Overview of Tango Collaboratory XII and DISA Meetings -- January--March 98. by Marek Podgorny


Sharing possible only if applications deterministic
  • applications ARE deterministic or can be made so
Copies of applications must be present everywhere
  • but they are, being applets or downloaded via a push channel
Environments must be identical
  • Java VM takes care about this
Initial state of a newcomer impossible to define
  • not so for good OO design and object serialization mechanism
Cannot maintain consistency among copies
  • Difficult ? Impossible. Variety of sync mechanisms available
Web model enables event broadcasting!
