Is there any way to customize every packet and send using UDP?

[lxdjame...@gmail.com]

I know "UdpEchoCilent" has a function "SetFill" that can set the content of packets for each client. However, I am wondering if there is a way to cutomize every packet to simulate the real data traffic? I know there is a class "Packet" but I do not know how to use it and send it. Any help would be appreciated.

Hi,

this has been covered many times.

Shortly put: it depends on the packet you have to build and how you plan to decode it afterwards.

Mind that the SetFill function (study it to learn how it works on a low level on the bare packet) is extremely powerful.

Hi Tommaso,

Thanks for your help. In this topic https://groups.google.com/forum/#!topic/ns-3-users/zZulmS2JR2E, someone said "If you want to have an application that sends different data for each packet, you need to develop it.". Is it also true for the newest release now?
