    62 To chose (and pay for) a higher bandwidth path (and higher cost), you will need to edit the config.txt file and replace the current policy that prefers low bandwidth paths.  In particular, you will need to change the line '''lb 1 USD''' to '''hb 10 USD'''.  This tells the wrapper library that you prefer high bandwidth paths for the iperf program and that you are willing to pay 10 USD for the paths you receive.  Having changed the policies in config.txt, all you need to do is to return iperf as you did above.

    6464Asking for high bandwidth paths results in the PS returning a high bandwidth path passing through the router HB.  As a result, the output from iperf should now jump to be roughly 7-8Mbps.

    68 Now repeat the test, but change the line '''hb 10 USD''' to '''hbhl 5 USD''' in the config.txt file.  This will cause the path service (PS) to return a path across the high bandwidth but also high latency path.  While this path will have worse performance than the HB path, it is more cost effective.
