[Ns-developers] New BulkSend application

[Josh Pelkey]

Gustavo,

Sorry for the delayed response.

just better documentation for OnOffApplication to explain to do bulk send
with it?

In order to create a "BulkSend" type application with OnOff, you must set
the OnTime to 1 (easy), but you must also set the DataRate appropriately so
that the buffer remains full.  You can see several examples where something
like this is used in the examples folder (search for WriteUntilBufferFull).
 So while it is possible to create BulkSend with OnOff, I think ns-3 could
benifit from a simpler-to-use BulkSendApplication.
