Re: mSQL Attack/Peering/OBGP/Optical exchange

I have received information on router utilizations, some routers it
seems may have held up better then others. That information is
useful. But I am working on some optical exchange point/optical metro
designs and this might have a dramatic impact if one considers things
like OBGP, Uni 1.0, ODSI etc etc.



A working hypothesis on the affect of this type of attack on a
dynamically allocated bandwidth network (such as an optical exchange
running OBGP etc) would have had a drastic affect on resources. All
the available spare capacity would have likely be allocated out. So
the "bucket" would have run dry. Understanding that exchange points
of this type (or metro area dynamic layer1 transport networks) will
manage the total bandwidth needs to always maintain adequate available
capacity





The problem with ONI and MP<whatever>S models is that there is little
or no correlation between the topology aware layers. You will most
likely sooner or later end up in a situation where the layers will
start to oscillate.



So, I would not build a optical IX around this model - if I would build
a optical IX at all.
