Frank-- Two times is sufficient for an invitation ;-))
I enjoy your informative posts on the many threads we cross on. The
wonders of the cyber-world. I have a hard time keeping up with you!!
..edge routing, while I was trying to lure my cyber-mentor Curtis into a debate!
OK, I'm getting sucked in-- Here are a few of my views on what is
happening in the BIG net. ISPs are changing to meet the needs of the
customers that they serve. The customers require secure connections
and that invokes firewalls; customers require security, authentication, encryption and all that--that invokes the whole suite
of things in what is called IPSEC, and the RFC's that describe it.
Virtual Private Networks, VPN's, which can be constructed using
tunnels (GRE tunnels), are required and all the *quality* kinds of
issues that go with all the above. Packet classification to allow
all of these things to happen is important and all of this is done
at the edge. Throw VOIP in there ;-).
So, if this is what you mean by taking the current intelligence out
of the core, then I agree--BUT--the intelligence requirements in the
core have changed--not getting stupid--just changing. The core needs
bandwidth--the edge gets more complex. The final end customer of an
ISP is currently bandwidth limited and fancy *quality* things have to
be invoked to allow that customer to choose the groomed traffic that
will flow to them. Tis getting better on the bandwidth front with
competition--take NYC as an example. You have some cool bypass
folks in operation there--MFNX, LVLT and more. Heck, I remember
when a intra-LATA DS1 costs 10K/month. You can get a DS3 from that
now, maybe even an OC-3c.
Europe is bandwidth deprived by PTNs but I see changes happening.
So, is that enough for a debate or questions ?? I got suckered ;-)) |
