Hi Sangita,
I see that there is another way to create different Interests. But I didn't
quite understand about the number of contents. In my case, I want to define
the maximum number of generated Interest packets in one step, and I want to
define the maximum number of generated Data packets in another step. Does
the line:
consumerHelper2.SetAttribute("NumberOfContents", StringValue("100"));
specifies the maximum number of Interest or Data packets?
My best regards,
Zakaria
