| For what it's worth, it's as close to in the RFC as it can get without a
| revision. The authors of the RFC agree that we meant the initial
| Request-Response RTT to be usable as an initial RTT estimate; the
| working group agreed; errata has been sent.
So we are RFC-compliant for the moment. One point which remains unresolved is,
the above is about RTTs, but what about the initial sending rate of 1 packet
per second, which implies an initial t_ipi of 1 second?
"Therefore, in contrast to [RFC3448], the initial CCID 3 sending rate is
allowed to be at least two packets per RTT, and at most four packets per
RTT, depending on the packet size. ..." [RFC4342, Sec 5]
Since CCID3 always has an estimate of the round trip time when it sends
packets, there is no such thing as an initial sending rate of 1 packet
per second. The initial sending rate, after the Response arrives (thus
providing an initial estimate of the round trip time), is 2-4 packets
per RTT, depending on s.
