Foil 17 Event Broadcasting: con and pro

From Use of Tango in Multidisciplinary Interactions MAPINT97 Workshop -- 16-18 June 97. by Geoffrey C. Fox, Marek Podgorny *

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