I used Pathcontrol with great success, moving bandwidth from one provider t=
o another at a very granular level. It beat the Netflow/CAIDA tools manual =
approach hands down. I don't understand the performance issue, though, and =
this is not the first time performance has been raised as an issue. Some ha=
ve seemed to think that the Pathcontrol existed inline in the data plane, s=
o, it was maintained, Pathcontrol could not scale to 10 GiGE and higher ISP=
links. But Pathcontrol was defined as a route-reflector BGP client in the =
control plane, and functioned as a method of calculating the fastest path t=
o destination BGP prefixes, and then advertising the best BGP route to IBGP=
route-reflector peers, which, in the absence of route table churn, did not=
require a super high-performing device.
Avaya should either bring the product back, or release the licensing for so=
meone else to use.

I used the PathControl for years (~2003-2007) and it rocked. We used
it for both performance and cost, preferring cheaper links as long as
the performance was comparable. It was super stable, I think we had
one or two problems with it the entire time it was installed. The
only drawback was it was too good, we got lazy and just let it do
everything.
