- This does not answer the questions above directly ... but just adds a
- comment to it.
-
- Back a year or more ago, I had implemented a protocol that ws inspired
- by the delta-T protocol, and attempted to Unify UDP and TCP in some
- sense, and work well over Thin-Wires. (below 300 bauds). The product of
- that work was called ALAP-GUT (with ALAP providing an IP like service
- with cut-thru routing to avoid packet framing delays) and GUT providing
- a Generalised User Transport Service.
-
- The effort was to gateway both TCP and UDP traffic back and forth
- and was achieved quite OK.
-
- In fact, this proved to be good enough to run telnet and talk over
- lines as slow as 50 bauds (yup, I needed to set up large Wide Area
- networks using Teleprinter lines !! Nightmarish ... but I'm not
- talking in my sleep :-) , running multiple hops, with the instant
- connection establishment features of GUT, adapted from Delta-T and the
- cut-thru source-routing of ALAP contributing very well.
-
- I guess I must wrap it up and write about it sometime ... Guess
- I need some pushing ! ;-)
-
- Is Delta-T being used someplace else ... I'd be very very keen to know!

- PS: Since this is the firt time I've had the oportunity to mention
- this, let me mention my tnx to Jon Postel for digging out the
- elusive IEN 116 for me when I was looking desparately for it, and
- also to the 60 students of PGDST90 at NCST, Bombay, who very eagerly
- implemented the stuff with great enthusiasm. I'd dedicate this to
- them one day, when I get to wrapping it up.
