This is one of the several public labs dedicated to fixing bufferbloat.
This lab is at the offices of the Internet Systems Consortium which is the home of the f-root server, ntp.org, the internet archive and many other wonderful projects. They have 10GigE connectivity to the internet.
Presently much of this lab has been dissembled and moved to yurtlab.
IPv4, native IPv6 and 6to4 are being tested on a cluster of 7 routers, 2 switches, a pair of PDUs and a perfsonar machine, and a network measurement box, equipped with multiple gigE and wireless-n interfaces. There are also various other random (and growing) pieces of test gear - olpcs, windows XP boxes, 802.11b gear, etc.
In addition to the normal core machines, there are also 2 meshed cerowrt routers spread throughout their (very large) building, doing network measurements as well.
All machines are in the .lab.bufferbloat.net subdomain. DNS for the lab is served by jupiter.lab.bufferbloat.net, signed with dnssec, which is, of course, a cerowrt router, also.
The principal public facing routers (jupiter and europa ) are equipped with strongswan and web and rsync servers for network measurements. Jupiter acts as a real-world native ipv6 gateway, europa used to act as a 6to4 gateway, and is now testing quagga-re. There is also a stock netgear router, also public-facing.
There is a native IPv6 /48 network in place behind the routers, with quagga doing BGP multi-homing (one day). We are in the process of adding snmp monitoring tools.
io.lab.bufferbloat.net is an x86 box equipped with multiple gigE cards and a wireless card for comparison purposes on the same wire.
Huchra.bufferbloat.net and shipka.bufferbloat.net, in the same data center are also in use for testing, but are used for production purposes.
All these machines have iperf and netperf running, although not configured the same all the time.
A babelweb instance was used on “io” to monitor the health of the routers.
All internal IP addresses are of the form: 172.29.X.Y.
For router’s main addresses, Y=1 (cerowrt 3.3 and later) or Y=33. The NETworks are the 172.29.X.Z networks they serve.
The ipv6 subnets follow a similar scheme, except in hexadecimal
2001:4f8:fff8:0X00::/56 per router, where X = the X in the ipv4 address.
