"It's nice to see that Vyatta isn't relying on open source's alleged good name along as it tries to carve out a prominent place in the networking realm. More young companies should have the guts to kick their rivals where it counts."
Unfortunately passe marketing tricks are about all Vyatta has going for them (and no I don't work for a gear vendor).
Their entire product line is based around commodity PC hardware. Performance is horrid compared to gear from any real vendor, where traffic is switched at a hardware level using dedicated ASICs.
The whitepaper on their site favorably compares the performance of a modern PC to an old, small Cisco router designed to route T1s (1.5mbit/s), something even a 486 could handle.
Apparently this means they "beat cisco."
Additonally there's really nothing their product offers that a competent administrator with a copy of FreeBSD couldn't brew up in an hour or two.
There is no way CPU based switching can handle the traffic of a Cisco 6500. There's a reason Real ISPs use Real Hardware, and not just off the shelf Dell boxes to route their traffic, and it's not because they don't have "super magic open source Vyatta software."
