title: Cybersecurity (Internet topology classification)
body: <p>I am trying to draw some insights on a set of Autonomous System (AS) relationships given to me. Data looks like this -</p>
  
  <pre><code>as1   as2   relationship
  
   4     567      0       
  
  14     6079     0
  
  18     276      0
  
  18    26468     0
  
  24     293      0
  
  24    6509      0
  
  24    7575      0
  
  24    10343    -1
  
  24    11537     0
  
  24    19401     0
  
  24    27750     0
  
  26    19401     0
  
  31    567       0
  
  32    71       -1
  </code></pre>
  
  <p>I believe that 0 and -1 indicate whether relationship is c->p or p->p, but I am not sure. Please help me identify what this data actually means and what insights could I possibly draw from a set of 250000 such points spread over 2 days and how?</p>
