Dear Peter; There is software and a program to do this. 1.) Multicast enable your network. 2.) Install AccessGrid / NLANR beacons : http://dast.nlanr.net/Projects/beacon/ 3.)

Dear Peter;
There is software and a program to do this.
1.) Multicast enable your network.
Good plan no matter what.
2.) Install AccessGrid / NLANR beacons : http://dast.nlanr.net/Projects/beacon/
Useful for rtt, etc..
3.) Monitor away : http://beaconserver.accessgrid.org:9999/
This doesn't solve the http://get/ part of the situation. good idea: Someone with a fast machine with reasonable memory+time to insure the scheduler is used properly could do something like the following install vmware on a host machine (www.vmware.com) set up a few 'virtual' machines, insure they can not use more than X% of the overall cpu set up rate-limit on upstream router (or similar router configuration commands) to prevent user from abusing the link. you could then install (linux|(Open|Net|Free)BSD|Win(95|98|NT|2k|me)) within the guest machine and set it up to have a seperate ip address and let people run whatever they desired. Obviously there are a few disk space, and memory as well as other resource allocation issues on the 'host' machine, but they can be resolved fairly easy. This would allow people that want to do this to offer many OS'es on a single machine. (ideally for free for people to do interesting traffic matrix things). I am going to ignore the tcpdump/packet sniffing abilities of each virtual machine to talk to each other as well as the other security aspects of this idea. obviously you want the people involved to be 'trusted' sufficently to offer these services. One could always generate some software daemons that can be connected to that perform these exact tasks also. the vmware idea is neat because you can offer access to development tools and customize rate-limits, etc on a per-IP basis and do some interesting things as far as network testing. - jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.

This is a very good idea. If you want to use www.gitoyen.net, ask me in private.

Unfortunately, there is no such list for Europe :-( The closest is lir-wg@ripe.net which talks more about bureaucratic issues and less about technical ones.

A Web site to exchange easily beacon hosts would be a great idea. That's why I reply in public.

Would eof-list@ripe.net fit the bill? Charter: The European Operators Forum deals with the operational issues of networks in Europe, such as new backbones and Internet Exchange Points. Rob

I'm a member of that list. Traffic is almost nil. Also, it depends on RIPE which is not good if you want to bash RIPE.

All the more reason for injecting some life into it. :)

Why? Is it moderated? If you have a reason for RIPE-bashing, I'd have thought RIPE lists would be the perfect place to air your views so "they" might listen. Might be best to take followups off NANOG, as this is starting to stray. Rob

Would you like to elaborate on that last part, please? BTW, feel free, within measure, to use www.ripe.net as a beacon host. Location is Amsterdam, The Netherlands. Joao Damas RIPE NCC --

I'm sure we could do something similar, if we could get access to a similar set of targets in exchange.

It would probably be nice to have some sort of moderated machine-readable list of targets, with geographical locations, and a simple bit of code to pick a "random" set of hosts to sample, such that you can build up a profile of network performance to geographic areas of the internet (transfer rate, hop count, RTT, packet loss). I'm fairly sure there's commercial services which offer this, but it wouldn't be too difficult to build a freeware solution.

Sure, if this turns into something we can all gain something from, we'll be interested, and will probably put up a box to support it.

Witbe, for instance (http://www.witbe.net/) but an exchange point (a marketplace of beacon hosts, on the Web) would be a grassroot and free alternative.

I have had many positive replies both public and private. I will summarise to the list in the next day or two and thanks for all the kind offers. Peter
[catching up on old nanog mails] there is a distributed project out there somewhere for doing just this. (Multiple sites, distribution of URLs to be monitored, etc.) <URL:http://webperf.org/> is it, I think. James.
