I used Pathcontrol with great success, moving bandwidth from one provider to 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 have seemed to think that the Pathcontrol existed inline in the data plane, so, 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 to 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 someone else to use. -----Original Message----- From: Gregor Visconty [mailto:gvisco...@gmail.com] Sent: Tuesday, August 23, 2011 11:15 AM To: Drew Weaver Cc: nanog@nanog.org Subject: Re: Route Optimization Software / Appliance 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. -Gregor On Tue, Aug 23, 2011 at 10:34 AM, Drew Weaver <drew.wea...@thenap.com> wrote: > Honestly someone should just convince Avaya to opensource and/or sell the > Route Science product. > > It's only real flaws (even today) are the performance of the hardware it was > built on and the lack of IPv6 support. > > Give it an x64 kernel that supports 32GB of RAM and you could probably still > be using it today. > > -Drew > > > -----Original Message----- > From: David Israel [mailto:da...@otd.com] > Sent: Tuesday, August 23, 2011 12:12 PM > To: nanog@nanog.org > Subject: Re: Route Optimization Software / Appliance > > > This is basically Arbinet's "Optimized" product; it uses actual > measurements for loss, round trip time, and jitter to choose routes. > Right now, it is just sold as a service, going through the providers > they sell access to; I don't know if you could purchase/license the > software for your own use. > > -Dave > > (Full disclosure: Arbinet is my current employer.) > > > On 8/22/2011 1:27 PM, Babak Pasdar wrote: >> Hello Group, >> >> I was wondering if anyone could share their experience with any route >> optimization approaches, methodologies or platforms, either open source or >> commercial (Internap FCP), that can actively adjust BGP parameters based on >> latency and number of layer 3 hops to a network rather than AS hops.
