We propose to send in the following erratum about RFC 4342 initial
sending rates. Any comments?
RFC 4342, "Profile for Datagram Congestion Control Protocol (DCCP)
Congestion Control ID 3: TCP-Friendly Rate Control (TFRC)"
Reported By: Eddie Kohler, from Arjuna Sathiaseelan
Date:
Section 5, 6th paragraph:
Explanation: Clarification of initial sending rates
It states:
Translating this to the packet-based congestion control of CCID 3,
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. The initial rate is only allowed to be three or four packets
per RTT when, in terms of segment size, that translates to at most
4380 bytes per RTT.
It should say:
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. The initial rate is
only allowed to be three or four packets per RTT when, in terms of
segment size, that translates to at most 4380 bytes per RTT. This
might be implemented, for example, by setting the initial sending
rate to min(4*s, max(2*s, 4380 bytes)), where "s" as usual is the
packet size in bytes.
