I guess that is a misrepresentation. You can send "real" data between
transport agents by putting them in the userdata_ (or some similar
fields) field in a Packet. To facilitate that goal and to provide a
uniform interface for passing application data, AppData was
introduced. You can find a summary in that application part in the ns
manual. 

Alternatively, you can instrument existing transport agents, e.g., udp, or
write your own agents to handle data in your own format, for example, the
SRM agent.
