Hi,
Is it fair to say that most traffic drops happen in the access layers, or
the first and the last miles, and the % of packet drops in the core are
minimal? So, if the packet has made it past the first mile and has
"entered" the core then chances are high that the packet will safely get
across till the exit in the core. Sure once it gets off the core, then all
bets are off on whether it will get dropped or not. However, the key point
is that the core usually does not drop too many packets - the probability
of drops are highest in the access side.
Is this correct?
Glen
