PCI bus bandwidth is just not an issue in this application at all. The FreeBSD part of the juniper router has a an Ethernet interface on it for management and control purposes; it's primary job is to run the routing protocols. As far as performance, it's just not meaninful to talk about packets per second and the like. The only important measure is "wire-speed forwarding performance on all interfaces all the time regardless of packet size." On a box with 8 OC-48c interfaces (2.4 Gb/s, full duplex), this sure doesn't involve a bunch of boards on a PCI bus. louie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
