    8384We are now ready to ask graphs of traffic on the four links of our topology.

     1251. At this point you will see four graphs showing traffic on each of the four links on your experiment.  The traffic you see on the links is broadcast traffic from the switch on the rack to which these nodes connect.  It is not related to your experiment.

     134     <li> Use the client.py program to fetch precipitation data for a time period you had not previously fetched.  This is to make sure the data will be fetched from the data source (<tt>dsrc1</tt>) and not from the cache at some node.  The time period must be between 1 Jan 1901 and 31 Dec 31 1902. </li>

     1412. Your graphs should now show traffic on the {{{rschr-router}}} and {{{router-dsrc1}}} links (see example below).  This is because the precipitation data was not cached anywhere and had to be fetched from the data source.
