Slide 11 of 21
Notes:
observations:
some consistently high regardless of type of access link (same top 3)
some consistenly low, regardless of type of access link (same botom 5)
some high for one type of access link and low for another
This isnít quite a POP-to-POP matrix. Actually it is a matrix between a single ingress access link and all egress POPs. The POP-to-POP matrix would be the sum of the next 4 graphs (plus the missing access links).
