Connectivity

Defines the core communication and authentication protocols required for Grid-specific network transactions.
Communication uses TCP/IP, DNS.
Authentication demands:
- Single sign on.
- Delegation: let this program access those files.
- Integration: with Kerberos and Unix.
- User-based trust relationships: If I can use A and B then my program should be able to use both together.
Globus implements the public-key Grid Security Infrastructure (GSI) protocols which extend TLS.
