Most protocols discussed on the net are standard interactive stuff; i.e.,
an acknowledgement of some sort is generated by the recipient upon successful
transmission.  I have an application for a uni-directional transfer where
acknowledgement is not possible.  Does anyone know if there has been any
detailed work in this area and where I might find it?

Thinking about the problem, it must be similar to a telemetry application,
particularly in a deep-space environment where acknowledgement would be so
delayed, if otherwise possible, as to be pointless.  Is the only solution
for reasonable probability of success to retransmit several times?  If so,
are there any formulas available to predict success as a function of, say,
number of transmissions and quality of circuit?

Thanks for any assistance available.  I'd especially appreciate any referrals
to books or articles.  If there is any general interest, I'll be happy to
post a summary of the response.
