paqet
Ferries Packets Across Forbidden Boundaries
paqet is a bidirectional packet-level proxy that transports traffic over raw packets instead of relying on the host operating system’s normal TCP/IP stack. It forwards traffic between a local client and a remote server using KCP as the reliable transport layer. The project is written in Go and is aimed at users who need a low-level tunnel that can operate in restricted or heavily filtered network environments. It is described as an alpha-stage tool, so compatibility and protocol behavior may change between releases. Paqet is most relevant to technical users who are comfortable with raw sockets, server-client tunnel setup, and system-level networking requirements. It should be used responsibly for authorized connectivity, testing, and research scenarios where the user controls the infrastructure. -

KCP
A fast and reliable ARQ protocol
KCP is a fast and reliable protocol that can achieve the transmission effect of a reduction of the average latency by 30% to 40% and reduction of the maximum delay by a factor of three, at the cost of 10% to 20% more bandwidth wasted than TCP. It is implemented by using the pure algorithm, and is not responsible for the sending and receiving of the underlying protocol (such as UDP), requiring the users to define their own transmission mode for the underlying data packet, and provide it to KCP in the way of callback. Even the clock needs to be passed in from the outside, without any internal system calls. The entire protocol has only two source files of ikcp.h, ikcp.c, which can be easily integrated into the user's own protocol stack. You may have implement a P2P, or a UDP-based protocol, but are lack of a set of perfect ARQ reliable protocol implementation, then by simply copying the two files to the existing project, and writing a couple of lines of code, you can use it. -
