*Hi Pascal and Jonathan,Thank you very much for draft-thubert-roll-forwarding-frags-02,Abstract:In order to be routed, a fragmented packet must be reassembled at every hop of a multihop link where lower layer fragmentation occurs. Considering that the IPv6 minimum MTU is 1280 bytes and that an an 802.15.4 frame can have a payload limited to 74 bytes in the worst case, a packet might end up fragmented into as many as 18 fragments at the 6LoWPAN shim layer. If a single one of those fragments is lost in transmission, all fragments must be resent, further contributing to the congestion that might have caused the initial packet loss. This draft introduces a simple protocol to forward and recover individual fragments that might be lost over multiple hops between 6LoWPAN endpoints.We would like to know please how you see that this draft is aligned with the roll charter, it seems that the intention is in this thread: http://www.ietf.org/mail-archive/web/roll/current/msg07784.html <http://www.ietf.org/mail-archive/web/roll/current/msg07784.html>, is that correct? do you have some additional information for intention? Thank you in advance,Michael and Ines.*
