Scenario: Web Portfolio Manager
Latency: Observation = ~0 (triggered by update 15 mins after stock prices change), Delivery = HTTP connection
Intermediation: Portfolio Server computes total portfolio value before sending information to the client
Initiator: Portfolio Server receives “pushed” quotes from Stock Server, does recalculation, then initiates with client
Delivery Constraints: Reliable Connection
Notification Management:
- Client subscription request enumerates current holdings
