Wireshark · Wireshark-users: Re: [Wireshark-users] Fwd: sequence number and packet id

["Fabiana moreno" <fvmoreno@xxxxxxxxx>]

thanks but i did some research already about the subject...
this is what i found...

http://www.freesoft.org/CIE/RFC/1889/9.htm

sequence number: 16 bits

The sequence number increments by one for each RTP data packet sent, and may be used by the receiver to detect packet loss and to restore packet sequence. The initial value of the sequence number is random (unpredictable) to make known-plaintext attacks on encryption more difficult, even if the source itself does not encrypt, because the packets may flow through a translator that does. Techniques for choosing unpredictable numbers are discussed in [7].

So i might be wrong, but i dont think sequence number represent how much data is being sent.
