The following may be of interest to some of you. The Telecommunications Industry Association (TIA) has started a new project (TR-41.3.4) to create a standard for "Performance and Interoperability Requirements for VoIP Telephone Terminals. First meeting will be the Monday of the next TIA meeting Feb 15-19 in Sarasota. They plan to establish relationships with related work in the IETF, ITU and ETSI. > Press release is online at > http://www.tiaonline.org/pubs/press_releases/1999/99-11.html > > Nancy > -------------------------------------------------------------------------- > Nancy M.

Hi Paul, I received two responses to my question, one from you and one from Tom Taylor. The fact that there are at least two people that know about it (and several dozens more that have actually implemented the protocol stacks), makes it hard to believe that this is an "oversight" in the recommendation. In fact, not knowing about this makes it impossible to implement an interoperable protocol stack! Shouldn't action be taken to get this into the recommendation ASAP (e.g. through the Implementor's Guide)?

Please note the following excerpt from Section 2/APC-1485 (Report of the Torino meeting): ------------------------------------------------------------------- The meeting notes that contributors are requested to upload the documents on time, otherwise their proposals can legitimately be rejected on the ground that the group members lack reviewing time. Contributors are also requested to pay attention to the ITU-T copyright policy when producing their documents. ------------------------------------------------------------------- Please quickly advise me if anyone is planning to submit a contribution or have discussion on the security aspects at the Monterey meeting.

TPKT is a necessary addition to TCP-based messaging, to provide advance delineation of individual messages. TCP by itself doesn't do this very well, since it is stream-oriented.

TPKT is defined in RFC 1006. Not identifying TPKT was an oversight that has never been fixed in the Recommendation. Paul Long Smith Micro Software, Inc.
