Performance metrics used in commercial BGP route optimizers

Wed Jul 17 18:51:08 UTC 2019

I was attracted to BGP route optimizers for latency/jitter reduction and
partial black hole detection scenarios.  Our traffic is low enough in
volume that we aren't playing the circuit commit game, but rather
optimizing the path to VoIP customers who don't care that provider Y in
path X-Y-Z had a fiber cut causing issues with their phone service.

They are a piece of the SDN and automation fun. Hopefully the vendors will
devise ways of dealing with traffic load balancing without splitting
prefixes.Or maybe RPKI will become more ubiquitous and leaks won't be as
painful. Similar to how DNSSEC led many ISPs to remove their DNS
redirecting "search services".
