Re: Route optimization using GPUs?

[Jason Bothe via NANOG <nanog () nanog org>]

WIth merchant silicon getting faster and stronger everyday, and capacity and transit in a freewill, I’m not sure what 
GPU optimization would buy you, not to mention the ROI. The Internet routing table is not showing substantial signs of 
growth and in some cases has experienced a plateau. Also, the experience with ‘route optimization tools’ is that while 
they may bring you some priority in your traffic, they are also known for making horrible decisions resulting in 
widespread outages.
