Is this the correct interpretation ??? I seem to recall that I asked a similar question a while back, and while I do not have a definitive answer, I tend to agree with your interpretation: (a) Just do a simple binary exponential backoff, i.e. double the interval on every retransmission. (b) Back off for individual messages, not whole sequences. This is because there is no way to shrink the interval with exponential backoff, therefore you might soon end up with a very large interval and all its associated problems, foremost that of not being able to detect loss on time, just because a few messages had to be resent. > Thanx, > Chamikara Regards, Philipp Reinecke --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
