kcp-go - A Production-Grade Reliable-UDP Library for golang

•    Go

---

kcp-go is a Production-Grade Reliable-UDP library for golang.It provides fast, ordered and error-checked delivery of streams over UDP packets, has been well tested with opensource project kcptun. Millions of devices(from low-end MIPS routers to high-end servers) are running with kcp-go at present, including applications like online games, live broadcasting, file synchronization and network acceleration.

UDPspeeder - A Tunnel which Improves your Network Quality on a High-latency Lossy Link by using Forward Error Correction,for All Traffics(TCP/UDP/ICMP)

•    C++

---

A Tunnel which Improves your Network Quality on a High-latency Lossy Link by using Forward Error Correction. Assume your local network to your server is lossy. Just establish a VPN connection to your server with UDPspeeder + any UDP-based VPN, access your server via this VPN connection, then your connection quality will be significantly improved. With well-tuned parameters , you can easily reduce IP or UDP/ICMP packet-loss-rate to less than 0.01% . Besides reducing packet-loss-rate, UDPspeeder can also significantly improve your TCP latency and TCP single-thread download speed.

tinyfecVPN - A VPN Designed for Lossy Links, with Build-in Forward Error Correction(FEC) Support

•    C++

---

A Lightweight VPN with Build-in Forward Error Correction Support(or A Network Improving Tool which works at VPN mode). Improves your Network Quality on a High-latency Lossy Link. tinyfecVPN uses Forward Error Correction(Reed-Solomon code) to reduce packet loss rate, at the cost of additional bandwidth usage.

Sia - Your decentralized private cloud

•    Go

---

Sia is a new decentralized cloud storage platform that radically alters the landscape of cloud storage. By leveraging smart contracts, client-side encryption, and sophisticated redundancy (via Reed-Solomon codes), Sia allows users to safely store their data with hosts that they do not know or trust. The result is a cloud storage marketplace where hosts compete to offer the best service at the lowest price. And since there is no barrier to entry for hosts, anyone with spare storage capacity can join the network and start making money.

A Reed-Solomon error-correcting encoder/decoder library written in C. Useful for forward error correction applications such as streaming audio, magnetic and optical storage, or just plain amusement value. GPL license with commercial license available.

BaconQrCode - QR Code Generator for PHP

•    PHP

---

BaconQrCode is a port of QR code portion of the ZXing library. It currently only features the encoder part, but could later receive the decoder part as well. As the Reed Solomon codec implementation of the ZXing library performs quite slow in PHP, it was exchanged with the implementation by Phil Karn.

udp2raw-tunnel - A Tunnel which Turns UDP Traffic into Encrypted UDP/FakeTCP/ICMP Traffic by using Raw Socket,helps you Bypass UDP FireWalls(or Unstable UDP Environment)

•    C++

---

A Tunnel which turns UDP Traffic into Encrypted FakeTCP/UDP/ICMP Traffic by using Raw Socket, helps you Bypass UDP FireWalls(or Unstable UDP Environment). It can defend Replay-Attack and supports Multiplexing. It also acts as a Connection Stabilizer. When used alone,udp2raw tunnels only UDP traffic. Nevertheless,if you used udp2raw + any UDP-based VPN together,you can tunnel any traffic(include TCP/UDP/ICMP),currently OpenVPN/L2TP/ShadowVPN and tinyfecVPN are confirmed to be supported.

udptunnel - It allows TCP/UDP/ICMP traffic over UDP tunneling

•    C

---

It allows TCP/UDP/ICMP traffic over UDP tunneling. It's useful to avoid Internet restrictions. So far, I've tested this technique in an OSX machine (connected to cellphone) and a Linux machine (connected to full access Internet connection). Once you have access to mobile operator's portal cautivo, you can access to limited services, such as DNS, and TCP ports distinct to 80 (HTTP). I don't use proxy over TCP because TCP connections receive an arbitrary RESET at any time. Also, I figure out that 53 UDP port has the best performance, with lower packet loss.

PacketSender - Network utility for sending / receiving TCP, UDP, SSL

•    C++

---

Packet Sender is an open source utility to allow sending and receiving TCP, UDP, and SSL (encrypted TCP) packets. The mainline branch officially supports Windows, Mac, and Desktop Linux (with Qt).
