If the smoothed RTT kept by the TCP sender is currently 30 ms and the following measured RTTs are 26, 32, and 24 ms, respectively, what is the new RTT estimate?

The RTP incorporates a sequence number field in addition to the timestamp field. Can RTP be designed to eliminate the sequence number field and use the timestamp field to resequence the out-of-order received packets? (Yes/No, why?)
