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. 126 127 {{{ 128 #!html 129 <table> 130 <tr> 131 <td> 132 <ol type='a'> 133 <li> Go back to the ssh window you used to log into the researcher node when you did the CCN exercise. </li> 134 <li> Use the client.py program to fetch precipitation data for a time period you had not previously fetched.

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. 142 143 Image( )
