The Talari device appears to operate like the old Routescience Pathcontrol BGP load balancer circa 2002 (Routescience is now owned by Avaya I believe). Routescience was able to compile the best path to Internet BGP prefixes so that a web site could connect to multiple 2nd tier ISPs (for circuit cost and redundancy reasons), and control the Mbps traffic over the best path, irrespective of the BGP feed supplied by the upstream ISP. In my experience devices such as Routescience automated the tedious work of using CAIDA tools to manually calculate the best BGP path to destination prefixes, and eliminated the almost daily reconfiguration of BGP route maps on Internet border routers. Routescience was a great product that put dashboard BGP routing control in the hands of the network engineer, and saved MRC circuit costs to pay for itself within a few months. -----Original Message----- From: Tim Utschig [mailto:tim@tetro.net] Sent: Tuesday, March 10, 2009 4:02 PM To: nanog@nanog.org Subject: Redundant Array of Inexpensive ISP's? [Please reply off-list. I'll summarize back to the list if there is more than a little interest in me doing so.] I'm curious if anyone has experience with products from Talari Networks, or anything similar, and would like to share. Did they live up to your expectations? Caveats? -- - Tim Utschig <tim@tetro.net>
