Lan connection throughput measurement

[Krystian.]

Im looking for fairly easy and reliable way to measure Lan throughput between 2 Lan cards in one PC (lan cards connected with hub). Ive found simple example with ftp server but it wasnt accurate enough comparing with other software. 

thanks

Krystian,

We typically use a ping command from a command prompt invoked in Labview which will get you accuracies in the ms.  Is this fast enough or do you need <1ms accuracy?

Ping would be good for round-trip times.

Throughput tests would involve passing different sized data sets from one node to the other, then dividing the data set size by the time required to transfer.

Krystian,

For accuracy software may not be your best option.  You may want to look into hardware solutions such as Ixia (http://www.ixiacom.com/)

Thanks all

dont need extreme accuracy, as minimum I need to specify whether speed between 2 lan cards attached to one PC working with or 100Mbit or 10Mbit. 

sending different sized data sounds like plan
