[ns] How to perform actual data transmission in NS2?

[Teerawat Issariyakul]

Dear Ying,

In fact, NS2 can transmit actual data. But NS2 does not usually transfer
the entire file because it does not have to. What NS2 does is to specify
the file size and simulation the time that the time that the entire file
is received (of course there are details that I omit to say here).

You may use C++ class AppDataType and/or AppData (see file
~ns/common/ns-process.h,cc) to store the entire file. There is a string
which can be used to store anything you want.


For the information about classifier, please refer to chapter 8 of the
book from Springer:

T. Issaraiyakul and E. Hossain, "Introduction to Network Simulator
NS2", Springer 2008.
