Hi all. I have been reading through the minutes of the BoF in Berlin, and I think we have to discuss about some things, and then improve the documents and the charter proposal accordingly.
These things are to be discussed in the [email protected] mailing list. We would like to ask people interested to subscribe to that list, in order to get their opinions and to get a fruitful discussion ( <https://www.ietf.org/mailman/listinfo/tcmtf> https://www.ietf.org/mailman/listinfo/tcmtf). Reading the BoF minutes ( <http://www.ietf.org/proceedings/87/minutes/minutes-87-tcmtf> http://www.ietf.org/proceedings/87/minutes/minutes-87-tcmtf), if we remove TCP optimization from the proposal, these would be the remaining questions (IMO): 1) It is clear that some TCP functions can be impacted by TCM-TF, so let us assume that we remove from the charter the possibility of multiplexing TCP flows. Do we still need some of that TCP functions? If the answer is "yes", then we have a problem. 2) "This is not being done by a host; it is in network, if a separator does not include timing, it could lose delay signals for congestion control based on delay". 3) Path MTU discovery issues 4) Are we "adding latency and complexity to save relatively little bandwidth"? Additional delays: "bufferbloat - could be increasing buffers to group packets up." Are we adding undesired delays? 5) "Do vendors want standards in this space? There are a lot of proprietary products; I would like to hear from other vendors who also would like to see this." 6) "application can sometimes send multiple packets with the same message so that they have unique probability of loss (not correlated), this is an application choice that needs to be known by a tunnel." Any other questions? Thanks a lot, Jose Saldana
