Jonathan RFC2543 specifies in Section 10.5.1 that a server should retransmit a final response with an interval that starts at T1 seconds and doubles after each subsequent packet until the response has been transmitted 7 times. RFC2543bis-02 specifies in Section 10.3.1 that a server should retransmit a final response with an interval that starts at T1 seconds and doubles for each subsequent packet until it reaches T2 seconds. Why was this change made? Just curious for the rationale. The 03 version of the PRACK draft references the RFC 2543 and specifies that the retransmit interval be doubled until 96 seconds have elapsed from the first transmission. This makes a total of 9 transmissions (8 retransmissions). Some questions on this - 1. Why such a large value of 96 seconds was chosen when the final response for INVITE itself completes in 32 seconds? 2. Why is the retransmission of the provisional response in the 03 draft of 100rel modeled on the RFC2543 and not the technique proposed in the bis02? 3. Will the 100 rel draft be revised to match the bis02 or later version of the RFC? I also suggest that Section 7 explicitly specify that it refers to Retransmission Interval Computation for Reliable provisional Responses (not PRACK) although this can be inferenced from the context.
