What is bifrost? Small Linux USB For infrastructure For research Name of network and collaboration

Networking people Unix/Linux Needing a small flexible disto For who? Networking people Unix/Linux Needing a small flexible disto

Hardware selection Software selection Testing Development Objectives? Hardware selection Software selection Testing Development

Routing Firewalling Login services Traffic logging Gateways etc Basic funtions? Routing Firewalling Login services Traffic logging Gateways etc

Basic funtions? Routing Firewalling Login services Traffic logging Gateways etc Ipv4, ipv6

Routing uses tested versions of quagga Bgp, OSPF both Ipv4, ipv6

R & D Close collaboration with Linux networking Developers and industry NAPI (3 years) Pktgen, fib_trie, (routing algo) routing stats Etc, etc

Cache effect/Performance

Measuring throughput drops breakpoint capacity overload overload

Overall Effect Inelegant handling of heavy net loads System collapse Scalabiity affected System and number of NICS A single hogger netdev can bring the system to its knees and deny service to others March 15 report on lkml Thread: "How to optimize routing perfomance" reported by Marten.Wikstron@framsfab.se - Linux 2.4 peaks at 27Kpps - Pentium Pro 200, 64MB RAM
