Well, it made most sense to me to ask for the HighSpeed TCP draft to be considered as an agenda item of tsvwg, and to be considered for an Experimental RFC, but if tsvwg decides otherwise, then that is OK by me. I just thought I would explain my reasons for asking it to be considered as a WG agenda item: * HighSpeed TCP proposes a rather significant change in the underlying TCP response function. Any such change would have to be globally agreed-upon. It seemed advisable to me to bring such a proposal to the IETF for feedback even in its preliminary stages. * While several people have conducted evaluations of HighSpeed TCP using simulations, my own belief is that the "real" evaluations will have to happen in experiments and in actual deployment. As part of this experimentation, HighSpeed TCP has been implemented in the Linux 2.4.16 Web100 kernel. It seemed to me that it was incumbent upon me, at this stage, to bring this to the IETF and to seek Experimental status. * I no longer view the world as divided between the "public" and the "private" Internet, with the IETF only concerned about the "public" Internet. I understand that there are ISPs, and parts of the net operated and controlled by governmental agencies (such as DOE and NASA in the U.S.) or by other institutions (e.g., schools), parts that are behind firewalls, etc. Thus, the fact that some/most/all(?) high-bandwidth transfers currently are on DOE/NASA/CERN and similar networks did not seem to me a reason not to bring something to the IETF. * A fourth reason to bring this to tsvwg is to get feedback, both positive and negative, from people who I don't happen to know, and who I would not otherwise talk with. Fortunately, this one can easily be satisfied simply by discussions on the mailing list, or on some other mailing list, and has nothing to do with being a WG item or with Experimental status one way or another.
