So back in the.. hell I don’t know like… early 2010s there was a push for ‘route optimization’ from products like RouteScience and the Avaya CNA and more recently whatever Noction is doing.

The big pain point for this technology at the time was that it could only optimize the top N egress routes due to how many probes it could send out and how many results it could process.

It seems like now with a modest GPU in a router you could pretty easily ‘optimize’ [to the extent that you believe this technology worked] pretty much the whole routing table.

We used these tools extensively back then and they actually worked pretty well in most cases. The biggest issue we ran into was people complaining that we pinged their IP addresses… which now a days seems like a great worst problem to have.

Anyway is anyone doing any work on implementing GPUs into the BGP decision making process? Seems like a no brainer.
