Your statement makes something of a presumption as to the architecture
of a network. In many networks, edge aggregation devices do not
participate in backbone routing, but simply pass the traffic they are
aggregating into the core.
One fairly well instrumented network that does have this edge/core
collapsed model is the Internet2 network. You can find a lot of
and other data for the network at:
You should be able to extract all the info you need from there.

In preparation of a course, I'm looking for reference material
report, talk...) giving real world data on the amount of transit
(ie. not locally dropped or added, but passing through to other
(backbone) routers) in a "typical" edge router of a core network,
ratio of local vs passthrough traffic (is it 30%, 40%...?) -- I don't
need absolute figures, just realistic estimates of that ratio.
Any help in locating such references would be highly appreciated.
