[comp.protocols.iso.x400] Why TP2? - an adhoc survey

ralph@geac.UUCP (Ralph Flotner) (08/31/89)

We are currently working with the ISODE package (which provides ACSE,
ROSE, RTSE, Presentation, Session, over TP0) which we have operating over
X.25.  We will be working primarily with X.500, X.400
and custom ROSE based applications, and occasionally with FTAM and VT.
Most of our traffic will originate from an X.500 DSA or an X.400 MTA 
(which in effect multiplexes user requests) and requires only one 
connection per remote DSA/MTA site.  

We are in the process of deciding whether to offer TP2 as well as TP0, 
over X.25.  
     TP2 would offer   i)  multiplexing (which we don't currently need)
                       ii) transport layer flow control (the merit of
                           which is unclear without multiplexing)

I am interested in what transport protocols others are working with, and WHY,
 - so I have prepared this simple survey:

Please fill out and return via email .... thank you in advance.

TP4 (Yes/No): ___   If Yes, Why? __________________________________________

TPx Package Name: _______________  Vendor: _________________________

If I receive more then 10 responses, I will summarize the results.
