   The H.323 Testbed
      Provide a web interface.
      Integrate with the IMAP email service.
      Web server (H.323 proxy using the upgraded Lucent Elemedia
       H.323 protocol stack).
      Relational database.
      Upgraded Motorola Vanguard H.323 gateway.
      Primary Rate ISDN line (24 simultaneous voice calls), 100 Mbits
       Ethernet.

Experiment 1: Congestion
Pricing
   Design Features:
       Provide real-time pricing & billing
        information.
       Allow callers and callees to split the call
        costs.
       Provide all the control functions through
        both the phones and the computers.
Experiment 1: Congestion
Pricing
    500 users using the gateway to make and receive
     telephone calls.
    Capacity limited to 24 simultaneous voice
     connections.
    First come first service with fat rate per minute
     leads to high utilization, but poor availability.
    Congestion pricing with price per minute
     depending on the network load can lead to high
     utilization and good availability.
         Price per minute can depend on the call duration.
         Price per minute can depend on the amount of usage in
          a time period.
        Experiment 2: Multiple Service
        Providers
          Logically: one service provider responsible for calls in each area
           code.
          Physically: emulate multiple service providers in our H.323
           gateway.

Experiment 2: Multiple Service
Providers
   Provide one integrated bill across multiple service providers.
   Perform settlements between service providers.
   Using a Clearing House to find the best path across multiple
    service providers.
   Allow the best path to change depending on the network
    conditions.
   See if prices can solve congestion across multiple service
    providers.
   See if prices can perform load balancing across the network.
   Provide mechanisms to deal with network stability issues.
Experiment 3: Multicast
Services
   Provide multiple party calls.
       Handles membership changes.
       Handles different link prices in the
        multicast tree.
       Allow members to negotiate how to split
        the cost.
Experiment 4: Reliable
Datagram Services
   Provide voice message delivery service.
       Sending reliable datagram across multiple
        service providers.
       Allow senders & receivers to negotiate on
        who should pay.
