Extended bandwidth/connectivity test

Hi
We have three sites - each connected with a VPN tunnel (CISCO asa 5505 or 5510 at the sites).

We do speedtests at each site, and they seem to be just fine, but what i'd like to do is an extended test between facilities - something like an application i run at each site, that connects to the other site, and just transfers data, measuring packet drops, jitter, bandwidth, etc.

Is there anything like that you can think of?

Ok here is a good discussion on iperf -- looks like just what you could use.

http://sourceforge.net/projects/iperf/

Download IPERF (linux src, etc or Windows binaries)

Select a "server" this is something on one side of VPN
iperf -s

Select a "client" this can be your system or something on remote side.
iperf -c x.x.x.x

Quick and dirty that'll test with TCP. Read the manual an you can select other options.

Iperf has the ability to push more than 99% of the users of this board can send/receive. So it will give you a decent benchmark.


Server side:
$ iperf -s -V

Client:
$ iperf -c <server address> -I <<< The server IP should be THE PRIVATE IP INSIDE THE VPN.

This will test base TCP performance inside the tunnel.

Read through the second link. Forcing to UDP mode will allow you to brute force your connection and see what you can possibly shovel through it.

+1 for iperf/jperf

also smokeping can be quite useful as well as something like mrtg to graph actual bandwidth used

2nd the SmokePing suggestion.  You can tell immediately by looking at the graph when something is amiss.
