Although this looks interesting, I'm unsure it will help these cell folks. Actually I can't tell for sure until Rick provides us with some more details of the exact issue at hand. NCR seems to deal with when the trigger loss recovery, whereas the cell phone network folks aparently want to jack up TCP_RTO_MIN so that hard timeout based retranmits are deferred a lot more than normal. And reading NCR some more, we already have something similar in the form of Alexey's reordering detection, in fact it handles exactly the case NCR supposedly deals with. We do not trigger loss recovery strictly on the 3rd duplicate ACK, and we've known about and dealt with the reordering issue explicitly for years. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
