    55The first !ChoiceNet service that we will use is the ''!ChoiceNet Source-Routed Forwarding Service'' described [wiki:GEC21Agenda/ChoiceNet/gt_tool  earlier].  We assume you have [wiki:GEC21Agenda/ChoiceNet/ already created two terminal windows], '''TERMINAL 1''' and '''TERMINAL 2''' that are logged into slice nodes '''H1''' and '''H2''' respectively.  You objective in this part of the tutorial is to run ''iperf'' between H1 and H2 several different ways:
     6 1. Requesting a low cost but lower-bandwidth path (and providing the payment need to get back low bandwidth paths from the PS)
     7 1. Requesting a higher cost but higher-bandwidth path (and providing the payment need to get back high bandwidth paths from the PS)
     8 1. Requesting a medium cost, high bandwidth but high latency path and providing the payment need to get back high bandwidth/high latency paths from the PS)
    69 1. Without providing sufficient payment to the ''path service (PS)'' -- which should cause iperf to fail
    7  1. Requesting a higher cost but higher-bandwidth path (and providing the payment need to get back high bandwidth paths from the PS)
    8  1. Requesting a lower cost but lower-bandwidth path (and providing the reduced payment need to get back low bandwidth paths from the PS)
    9  1. Requesting a medium cost, high bandwidth but high latency path and providing the payment need to get back high bandwidth/high latency paths from the PS)

    1011You will run your iperf server on H1 and the iperf client on H2.  For each test case, we will be able to see the throughput achieved by iperf, indicating that the PS found an appropriate path, and iperf received the requested performance characteristics.   If you are logged into the GENI Desktop, you will be able to visually see the traffic taking different paths across the topology.
