I have no experience with OER, but I have had a FCP5000 for a while
now. We have numerous transit links, all of which have significantly
more burst capacity than we actually use (or commit to). To some extent
it is a bit magical and I don't always understand how it decides the
"target" traffic level for a link, but in general it works great. Since
installing it we've pretty much done away with any other regular BGP
changes to balance traffic. It does a good job of keeping out many
transit links all below commit unless total traffic exceeds all commits.



We've used the FCP500 and FCP5000 for several years now, and though we
have had our ups and downs in terms of hardware failures, bugs, and
capacity concerns. I must agree that it does a very good job at the
basics of balancing out traffic for commits, bursting (based on cost)
and minimally for performance.



If you have transit and peering, there are some things about it that
don't fit real well into that model.








In general, I'm skeptical that it is really providing much of a
performance boost. However, it does a good job at balancing traffic
levels and that is the main value we get from the product. It was
basically a "fire and forget" system. Once installed, we were able to
just forget about traffic engineering and only touch things when
adding/removing a link (or for special situations like manually routing
around bad paths).



If you'd like technical information about how it works or the potential
scaling issues that can result let me know what you're interested in and
I can expand a bit.
