Subject: RTP - conflicting acronyms

I don't know if you care, but IBM has a protocol called "RTP" which
means "Rapid Transport Protocol".  It is part of Advanced Peer-to-Peer
Networking (APPN) High Performance Routing (HPR), the next-generation
SNA architecture.  RTP is defined by a draft standard of the APPN
Implementers' Workshop that is likely to receive final standards
approval at the next AIW meeting on May 1, 1995.  I am writing to you in
my capacity as Chair of the AIW's working group on HPR to point out the
possibly conflicting acronyms.

Having two protocols with the same name is likely to cause confusion.
Since IBM and the 40+ AIW member companies have been working on and
publicly discussing RTP for several years now, and many in the industry
will soon be shipping products with HPR's RTP, I would like to suggest
that your working group consider using some other acronym for your
"Transport Protocol for Real-Time Applications."

Speaking on behalf of IBM for a moment, it is unlikely that IBM would
change its "RTP" acronym, since this term is used in marketing materials
and it now has good name-recognition among customers.

The HPR specification that defines Rapid Transport Protocol is available
by anonymous ftp from the AIW document repository at
//networking.raleigh.ibm.com; the filename is
/pubs/standards/aiw/appn/hpr/hprspec-v2.psbin or .zipbin.

Thanks for your consideration.

Subject:  RTP

Marcia,
I don't suppose this RTP is the same as ours, and just wondered if the
duplicate names would cause problems for the IETF or us (e.g., bbns->nbbs).

No need to respond, this is just FYI.

The IESG has received a request from the Audio/Video Transport Working
Group to consider "RTP: A Transport Protocol for Real-Time
Applications" <draft-ietf-avt-rtp-07.txt, .ps> for the status of
Proposed Standard.

The IESG plans to make a decision in the next few weeks, and
solicits final comments on this action.  Please send any comments

RTP has also been a term that we use to describe what in this RFC too.

So why would you think other companies can handle the change of a more
public terminology?

A humorous ancedote on this acronym collision ... 

    I attended an Interop conference session last autumn in Paris
    entitled "High-Speed Transport Protocols".  They talked about TCP,
    XTP and some research work being done in Europe on high-speed
    transport protocols on top of IP.  The two main speakers were from
    IBM-Germany (ST-II folks, I think).

    After the session was over, I went up to the front to talk to one
    of the speakers from IBM about RTP (of the APPN variety).  He
    thought I was talking about IETF one ... he had never heard of
    APPN's RTP.

    Education begins at home :-).
