Prefix distribution: findings


Changes in global routing not captured by bulk 
     measures such as number of prefixes in a table

Net change is a sum total of commensurable
     contributions of opposite sign, so...
Total variation is not the difference,
     but rather the sum of their magnitudes. 

Most measures of routing system complexity 
     demonstrate slow growth, dynamic equilibrium 
     and/or decrease for May-Dec. 2001.

         Current state of the Internet routing system
         shows large variation but NOT rapid growth!
