Requirements
• Universal mechanism for integration
• Service architecture for scalability and
high availability
• Any-to-Any data type conversion
mechanism
• Mechanism for User-Preference
specification
• Name mapping across different types of
end-devices

Components of Initial Design
• NINJA service model for scalability and
fault-tolerance
• Operators, Connectors and Paths for datatype conversion
• User Preference & Name mappings stored
in “directory service”
• Preferences - should be in an active script
(not a static database)

• The Services
– Univ-Inbox Service - handles incoming and
outgoing calls
– Directory Service - stores name mappings and
preferences
– APC Service - Handles path creation for datatype conversion
• Univ-Inbox services make RMI calls
between themselves for call setup
• Directory service invoked at caller end
• APC service invoked at callee end

Problems
• Too slow: UPSim side, RMI
• Speech <--> Text problems
To do
•
•
•
•
Real-time data-type conversion
User-Preference script design
Make services run in iSpace
IP signaling protocol for call setup between
Univ-Inbox services
• DTMF signaling for vat
