Foil 28 Gateway Technologies

From Overview of Gateway Project DoD MetaSystems Workshop Charlottesville Va. -- August 11-13 99. by Geoffrey C. Fox, Bill asbury, Ken Flurchick, Tom Haupt


1 Built with multi tier architecture using secure CORBA and sophisticated WebFlow Java front end allowing task composition
  • tasks defined in XML and can be saved/re-executed/edited
2 Kerberos built on Secure CORBA today but PKI Security fine
3 All object interfaces defined in XML and so front end totally independent of middle tier implementation
4 Supports Dataflow and more general object based computing model (executing objects linked by events)
5 Middle Tier Components based on Javabean model
6 Custom Middle-tier event model consistent with security
7 Middle Tier is wrappers (proxies) and so insensitive to performance problems in CORBA or RMI
8 XML Interface between Middle Tier and backend -- object model for backend not required
