You may find this interesting: http://simet.nic.br/ NIC.br has it deployed nation-wide in Brazil, with remote endpoint servers in most public IXPs ("PTTMetro" IXPs, which are also managed by NIC.br). The end user client is available over the web (java applet), and also as a mobile app for Android and iOS. There's also an openwrt-based firmware for a very inexpensive home-router box ("SIMET box"), which they've been giving out to the general public so as to increase their test coverage. SIMET does bandwidth (TCP and UDP) as well as latency and jitter measurements, but it doesn't attempt to measure bufferbloat so I never thought of mentioning it around here. One interesting detail is that SIMET measurements are trusted (as in "can have legal standing in Brazil"): the SIMET system is certified[1] by INMETRO, Brazil's national body for scientific, industrial and legal metrology. There's not much material in english about SIMET, unfortunately. Outside of Brazil, I like the Berkeley ICSI Netalyzr (http://netalyzr.icsi.berkeley.edu/). VERY comprehensive measurements and several network diagnostics... and it does measure worst-case steady-state latency (aka bufferbloat). [1] "certified" is not exactly correct. I don't know an exact word in english for "has been verified to be correctly calibrated in accordance with the official measurement standards and procedures", in portuguese: "aferido". -- "One disk to rule them all, One disk to find them.
