Dealing with lossy links?

Posted by Anonymous on Tue 12 Dec 2006 at 09:35

Sometimes you have to deal with lossy IP connections. Your ISP has packet loss somewhere, or a cable in your network is rotten, or a switch is soaked with traffic.

While most of the time it's best practice to tackle the source of the problem, sometimes you just have to get tough.

Possibly because you're the admin trying to fix things, or because you have life-saving important data that you must transmit at the expense of your neighbour's bittorrent practices.

I'm looking for a system to minimise the effects of this.

Currently I'm thinking about a VPN over UDP (nicely transparant for all IP applications) that does redundant transmits, eg each packet twice or three times depending on the loss.

A Linux client is of course mandatory, and a Debian vpn terminator (set up beforehand) wouldn't hurt.

Any ideas?
