[AVT] RTP - Last sequence number vs highest sequence number

["pieter.demuytere" <pieter.demuytere at intec.ugent.be>]

Hi all,

In RFC 3550, the number of packets expected is defined to be the 
extended last sequence number received less the initial sequence number 
received. However, in the example code given in appendix A.1, the 
(extended) highest sequence number is used, and not the (extended) last 
sequence number. My feeling is that the last sequence number received is 
not automatically equal to the highest sequence number received, due to 
packet reordering. Is it allowed to use the (extended) highest sequence 
number for the calculation of the number of packets expected?

Thanks
Pieter Demuytere
