## What it is
A lightweight Linux VPN tool that uses Reed-Solomon forward error correction to reduce packet loss and improve TCP latency on high-latency, lossy network links. It runs in VPN mode over a tun device and shares its FEC library with the UDPspeeder project.

## Use cases
- reduce packet loss on a high-latency lossy link
- improve TCP download speed over a lossy connection
- establish a VPN with built-in forward error correction
- make SSH/SCP transfers usable on 10% packet-loss networks
- run a VPN on an OpenWRT router or Raspberry Pi
- lower ping packet-loss rate to under 0.01%

## When to choose
- your link has significant packet loss that FEC can compensate for
- you can spare extra bandwidth for redundancy packets
- you run Linux hosts, routers, or embedded ARM/MIPS devices
- you need IP-level (not just UDP) traffic improvement via a tun VPN

## When to avoid
- your link is already reliable and low-latency
- you need Windows/macOS native support (only via a VM image)
- bandwidth overhead from FEC redundancy is unacceptable
- you need a full-featured VPN with strong encryption or multi-user support
