Re: RTP v/s UDP

Try
RTP http://tools.ietf.org/html/rfc3550
UDP http://tools.ietf.org/html/rfc768

The UDP protocol can carry RTP as it's payload.

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.html link 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..

    Hi,
      Goggling for VLC player found http://www.videolan.org/vlc/ very
    breifly looking at the info it looks like there are several options
    for how the video stream is sent if it really is RTP in your case
    you could use decode as and select RTP and then use the RTP analysis
    Note that it designed to analyse Audio and some values may not be
    entirely correct/applicable for Video.

    You can also use the IO-graph to calculate the  bandwidth. If RTP
    isn't used you may have to digg trough the documentation/sources
    of the VLC player to find out if you can do the calculations you
    need. You may have to export the data from the RTP analysis and
    perform your own calculation from the raw data or update
    Wiresharks sources to do it for you. You may also have to know
    what codec(s) are used to do correct calculation. You must also
    consider where your traces are made and perhaps compare results
    from the sender side with results on the receiver side. No easy
    answers here :-)
    Regards
    Anders

    Hi Antony ,
      Thanxs for your response. What does this mean *"RTP is commonly
    carried within UDP"** ??* I found that wireshark provide support
    for RTP* *as http://wiki.wireshark.org/RTP_statistics* . If i
    need to calculate jitter,bandwith etc. What should i use. How can
    i use UDP

        Hi Ankur,

        RTP is commonly carried within UDP. Although this is not
        mandatory, there are other possible underlying protocols such
        as AAL5.

        Regards,

        Hello All,
          I am a new user of wireshark. I am working on stream video
        packets and receving at other end through wireless hops
        (Access point). I used to do this using VLC player and thru
        UDP protocol. I started using Wireshark for analysis of my
        packets. In between i found we cannot calculate jitter ,
        delay etc.. through UDP. Later i found RTP protocol. Now the
        question is what exactly is the difference between UDP and
        RTP in term of networking and in term of Wireshark s/w working.

        I need some proof as this information will be needed for my
        publication.
        Help me plz
