Re: RTP v/s UDP

[ankur aggarwal <ankur.mast.frn () gmail com>]

Hi Anders,
 Thanxs for the reply. My problem is bit different. I want to use UDP only.
As http://www.mail-archive.com/wireshark-users () wireshark org/msg03818.htmllink
suggest we cannot use UDP for these calculation, instead use RTP
directly. In my project i need to know the difference in RTP and UDP.


Can any body tell me how to convert .pcap (wireshark file) to excel file. I
found this link http://packetbone.com/ . But unfortunately i donot PC with
32 bit + XP in my lab..
