Summary: Looking for a File transfer protocol
Apparently-To: kermit.misc@watsun.cc.columbia.edu
I am looking for information on one-way file transfer protocols. What
I mean by this is a protocol that will support file transmissions in
which the receiving side has no transmission capability at all. It
cannot send flow control, error-checcking responses, or anything else
it might do in traditional ftp-style protocols. Ideally, some type of
error-checking information could be send with the file, so that the
receiving end could interpret what it has received, and establish
whether the transmission was corrupted or not.
I imagine that one could simply add up all of the bytes transmitted,
and then transmit that sum as a checksum byte. Unfortunately, this
would only allow the receiver to discard erroneous files, not correct
them in any way. If there is a more sophisticated type of one-way
transmission, I'd like to hear about it.
Does such a protocol exist? Is there some kind of a standard? Where
can I find out about it?
Please mail any responses to opel@leland.stanford.edu.
Also please understand that I am a bit of a novice on the issues
surrounding file transfers (if it's not obvious from the questions
that I'm asking...).
Thanks in advance,
Dylan Mackay
