Tools for Bandwidth Measurement?

[Dimpa1]

I have a cisco router connected to a vsat, which is suppose to give me 128K but it seems a lot slower than that.
What tools can I use to see how much bandwidth I have on a private circuit?

I use Iperf, it rocks. It is free, it is easy to use, and it supports multiple platforms. Here is a link to it:

From the commandline type iperf -s on the receiving end. Then iperf -c <ip address of receiver> on the other end. It will transfer data for 10 seconds and report back the throughput. It supports different port numbers, UDP and a number of other cool options.

I download it (windows) and I tried using the iperf.exe but I cant type anything on there. Am I suppose to install it on 2 pc, 1 at each end?

Yes, you need to run Iperf on both ends of the connection. On one end type:

iperf -s

This end will receive the data. On the other end type:

iperf -c <ip address of receiver>

This end will transmit the data. You must give the transmitter the IP address of the receiver.

MRTG is good for monitoring the router stats by all accounts and I am told PRTG is ok too.

I use SolarWinds Adbanced Bandwidth Monitor to look at the same stats, you can download a demo from the solarWinds website.

I use a SNMP monitor from Castle Rock, SNMPc is the name, is easy, fast, and complete.
