data throughput measurement on application layer

[punto]

Hello,
I would like to open a new subject , surely interested for all of us > data throughput measurements on application layer.

Please, share which SW tools and methods you use to measure 2G/3G data throughput measurements , and respond time of your networks ... could someone share some report and some advices and know how about measuring while making http, wap, email, DL UL ftp, ping ... ?

Lets share ...

Very Good Topic....

The VIP Members should response.....
I mean the super engineer...Hassen...

Hopefully Hassen is the right person for this topic..

thanks

I use the following tools in my company..

For application layer throughput monitoring..

Netpersec & DU meter

For latency measurements..

ping command from the DOS prompt & Perfping

For throughput measurements using UDP there is a very good utility called UDP flood that you can run on a test server hanging off your GGSN. This way you can measure throughput with worrying about TCP peculiarities..

[Mr.David]

ethereal is the usefull one

[hassen]

we use business objects for gprs statistical according to counters and formula
ping to know time responce
The use of WAP to access the various servers of the operators
create a session at SGSN and from drive test make downloading in order to measure
throughput .

Thanks Hassen and all

@all
Do you use only ping volume of the data 32 bytes ... to be assured that you have information how customer see response of your network ... or , you have done pinging with bigger then 32 bytes of volume of data sent by this command ... maybe, to be closer to simulate some service access , like http ? Logically I think, we should discard first PING result in making precise statistics of consecutive PINGs, as at start TBF takes time to establish ... and we are looking for average of all resuts made by some sequence (except that first longer one ... ) Do you agree ?

I would suggest varying the ping size in order to uncover any potential bottlenecks you might have. Perfping has a nice interface that allows you to do that and will also start off with a small ping packet and keep increasing it.

Thanks M
what is range of ping size/volume you set in Perfping ... from minimum xx bytes , to how mucho Max yy bytes ? Can you share with us install of these nice tools ? Correct me if I am wrong , but I am not sure they were offered by someone before ... If is not a hassle to you ... we know how to return smile and thanks ...

Also, here is link to many SW tools from the similar family of tools, like Perfping ... useful, scroll down ..

Actually Zte BSC use rollcall polling way to process ping test packets which is different from traffic packet. And the way increases the ping packets' delay..

"Because ping is only one test tool with which we test the link connected or not, so we use rollcall
polling way. With rollcall polling way, we can decrease the ping packets’ processing load and the
influence of normal traffic packets.
However we do not the rollcall polling way to process traffic packets. In one word, the delay of ping
packets does not mean that the true delay of traffic packets."

Any one can help me what is the acceptable RTT(latency) for both GPRS and EDGE .
