Hi Arjuna, CCID3 allows an initial sending rate of at least two and up to four packets depending on the packet size (up to 4380 bytes in the initial burst of three or four packets). Tom P. > -Original Message- > From: Arjuna Sathiaseelan [mailto:[EMAIL PROTECTED] > Sent: Wednesday, Augus

Hi Arjuna, By my reading of RFC 4342, it seems to be talking about the *initial* sending rate -- that would be before you know what the RTT is. Is this confusion over initial sending rate of 1 packet/second instead of 1 packet/RTT? They're functionally equivalent -- as soon as you get feedback f

Hi Tom, Thanks for your reply :). Yes it does, but I thought it was only after it has got a RTT sample (which is got by setting the rate to one packet per SECOND, sending that packet and when the feedback is received) and then setting to 2 or 4 packets per RTT? RFC 4342 says: "[RFC3448], Section

Dear All, I presume that CCID 3 is still following RFC 3448's slow start behaviour of 1 packet per second during the start of the connection, and when the ACK is received for that packet, the INITIAL ALLOWED SENDING RATE is set to 2 packets to 4 packets per RTT appropriately. Now my question is
