AS Summary
         35344  Number of ASes in routing system
         15034  Number of ASes announcing only one prefix
          4447  Largest number of prefixes announced by an AS
                AS4323 : 
      97312512  Largest address span announced by an AS (/32s)
                AS4134 : CHINANET-BACKBONE No.31,Jin-rong Street


Aggregation Summary
The algorithm used in this report proposes aggregation only
when there is a precise match using the AS path, so as 
to preserve traffic transit policies. Aggregation is also
proposed across non-advertised address space ('holes').
