There is no software involved in the forwarding plane, including the line cards, in the Juniper routers. There is another CPU in the box running an embedded system kernel, which does supervisory things, but that's also not involved in the forwarding operation. The forwarding is done in Juniper's custom designed ASIC hardware, and is the other significantly valuable intellectual property they have along with the routing protocol implementation (e.g., BGP, IS-IS, etc.) louie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
