rtp implementation

[Kamil Sarac <ksarac@cs.ucsb.edu>]

Hello all,
I have a question about rtp implementation in ns. There is a sample
script which has an rtp session in
~ns-2/tcl/ex/simple-rtp.tcl. But in the documentation, it also says that
rtp is not completely implemented.
I want to learn which parts of it are not  implemented.

My question is: Are the following features implemented or not?

1) timing of  rtcp packets depending on changes in number of
participants,
2) packet loss information of reception reports
3) jitter information of reception reports

Thanks in advance.

Kamil Sarac.
