CAIDA animated its observed AS core outdegree data between July 2000 and January 2002. As with the still image above, each AS represents a block of IP addresses controlled by a single organization, and relative outdegree reflects the richness of the connectivity of different ASes. Note that the large jump in connectivity that you will observe in July 2001 was the result of a substantial increase in sampling coverage by CAIDA monitors. Interestingly, the relative ranking of observed connectivity among major ISPs remained essentially unchanged.
