# UDPspeeder
Network Speed-Up Tool. Boost your Connection on a High Lantency High Packet-Loss Link by using Forward Error Correction.
When used alone,UDPspeeder speeds-up only UDP connection.Nevertheless,if you used UDPspeeder + any UDP-based VPN together,you can speed-up any traffic(include TCP/UDP/ICMP),currently OpenVPN/L2TP/ShadowVPN are confirmed to be supported。

For Windows and MacOS You can run UDPspeeder inside [this](https://github.com/wangyu-/udp2raw-tunnel/releases/download/20170918.0/lede-17.01.2-x86_virtual_machine_image_with_udp2raw_pre_installed.zip) 7.5mb virtual machine image.
# How does it work
UDPspeeder uses FEC(Forward Error Correction) to reduce packet loss rate,at the cost of addtional bandwidth.The algorithm for FEC is called Reed-Solomon.
