TOR Question

Hi,

   There was a thread on Nanog in January about TOR and deep buffers
(http://seclists.org/nanog/2012/Jan/966). I have a follow-up,
related question.

   Has anyone used a TOR switch to aggregate connections to from major
network providers? For example, 2 or more 10GE ingress connections
(pick your favorite CDNs) into one 10GE egress back to our router
(which is at a remote location). We are worried that queue buffers
are too small to handle the traffic going to the egress port.

Thanks,
Joe Lappa
