Conclusions



Internet undergoes refinement process 
Some bulk measures are stable
Others change slowly 
Opposite trends cancel each other
More churn than bulk measures suggest
Internet churn comes from everywhere
mostly from large ISPs, .gov/.mil, and developing nation telecoms
Small ASes generate little churn and table growth
Invariant or almost invariant relations do exist
e.g. AS paths/AS ratio 


still a lot left to analyze...
