Large-datagram hop-by-hop delivery mechanism
I am seeking a mechanism for reliable delivery of large blobs through a network of occasionally-connected hosts that can forward the blobs using available transport protocols. I can't find it, though. Most of the networking materials I can find deal more with immediate-transmission networks, where the destination host is reachable at the instant that the source host transmits. (This isn't a catenet.) If anyone knows of such a common or standardized system, please drop me a note. And if there's not already such a system, then we'll just have to make one. --- Mark R.

Sounds to me like UUCP. "Mark R. Lindsey" wrote:

sounds to me like email, where the sending host tries again and again over a defined period of time to delivery data. no? -- |-----< "CODE WARRIOR" >-----| codewarrior@daemon.org * "ah! i see you have the internet twofsonet@graffiti.com (Andrew Brown) that goes *ping*!" andrew@crossbar.com * "information is power -- share the wealth."

You could take a look at how networks of IRC servers or Usenet servers manage to remain connected or manage to push articles around even when large chunks of intermediate networks fail, or you could use some fancy mail routeing system and treat your blobs as email. Do the blobs have specific destinations (think Email), and even if they do is it acceptable for the blobs to also be delivered to every other host on your network (think Usenet) ? (In other words, you might need to look a couple of layers up from the network layer to get a good result on this one.)

UUCP. It does exactly what you just described. If you want to run over an existing IP network, use UUCP-over-TCP. <DIV mode=digression> You know, five years ago, we wouldn't have given a moment's thought to this problem, since the solving technology was so blatantly obvious.

(As I slowly try to hide in a corner so noone can see where this suggestion came from..) UUCP? All kidding aside, I'd love to talk about your applicaton off-list. - Forrest W.
