Programmers Stack Exchange is a question and answer site for professional programmers interested in conceptual questions about software development. It's 100% free, no registration required.

I have following scenario,

  • a central server which will receive all artifacts (it doesn't have to be software, just any kind of opaque blob)
  • a number of other machines connected with a low bandwidth connection to the same network (think UMTS or Satellite)
  • a large blob of software (around 300 MB) where a xdelta between the revisions is much smaller (a few KB to a few MB)

I need some kind of software which is able to distribute the artifacts, using some kind of delta, bandwidth throttling and the ability to remove older versions from its repository when they not needed anymore, a nice management GUI and it should work on linux and windows. Also it should be relatively lightweight and easy to install.

Is there anything like it?

Just a 2 cent, but the venerable rsync tool was designed with this scenario in mind. –  Steve Schnepp Jan 25 '13 at 12:05

I googled for something like this, but the only stuff that came up was not really what I was looking for. I want to have a slim solution, not TIVOLI. –  Mauli Jan 25 '13 at 14:13

Look into some of the work in the Amateur Radio community, especially from the 1990s, around using AX.25 to access amateur satellites (particularly the "microsats"). They had extreme bandwidth constraints and yet wanted to be able to upload and download (literally!) files between ground stations and orbit. Their work included other interesting aspects, like the improbability of being able to fully download a file during a single session, and blending partial downloads into a coherent result.

Ah, that brings back memories. A project I once worked on used AX.25 to transmit telemetry from a high altitude research balloon to the ground (ground software was basically a LabView interface). Very bandwidth constrained (maybe 1200 baud if memory serves)... but it worked. And it was fun. –  James Adam Jan 25 '13 at 13:47
