GameNetworkingSockets
Reliable & unreliable messages over UDP
GameNetworkingSockets is a basic transport layer for games. A reliability layer significantly more sophisticated than a basic TCP-style sliding window. It is based on the "ack vector" model from DCCP (RFC 4340, section 11.4) and Google QUIC and discussed in the context of games by Glenn Fiedler. The basic idea is for the receiver to efficiently communicate to the sender the status of every packet number (whether or not a packet was received with that number). ... -

TCP Optimizer
The TCP Optimizer is a free, easy Windows program that provides
...The tool uses advanced algorithms, and the bandwidth*delay product to find the best TCP Window for your specific connection speed. It provides for easy tuning of all related TCP/IP parameters, such as MTU, RWIN, and even advanced ones like QoS and ToS/Diffserv prioritization. The program works with all current versions of Windows, and includes additional tools, such as testing average latency over multiple hosts, and finding the largest possible packet size (MTU) -

Zapret
Advanced open source tool for bypassing DPI-based censorship
Zapret is an open source, cross-platform tool designed to help users bypass and evade Deep Packet Inspection (DPI)-based traffic blocking and censorship systems. Rather than acting as a traditional proxy or VPN, it works by manipulating network packets and traffic streams locally to confuse or disrupt DPI mechanisms used by ISPs and network filters, making it possible to access restricted websites and services without relaying traffic through third-party servers. Zapret implements multiple... -

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. ... -

SMTP Tunnel Proxy
A high-speed covert tunnel that disguises TCP traffic as SMTP email
SMTP Tunnel Proxy is a high-speed covert tunneling proxy that disguises regular TCP traffic as legitimate SMTP email communication to evade deep packet inspection (DPI) firewalls and censorship systems. It implements a SOCKS5 proxy interface on the client that wraps outbound traffic into an SMTP-like handshake (EHLO, STARTTLS, AUTH) and encrypted payload, making the session appear to DPI systems as a normal email exchange. -

fq
jq for binary formats
...It was originally designed to query, inspect and debug codecs and metadata in media files and containers like mp4, FLAC, mp3, and jpeg. But has since been extended to support a variety of formats like executables, and packet captures including TCP reassembly and serialization formats like ASN1 BER, Avro, CBOR, protobuf, and a lot more. In summary, it aims to be something like jq, hexdump, dd and gdb combined into one. fq is still early in development so things might change, be broken, or do not make sense. That also means that there is a great opportunity to help out! -

modbusmplex
modbusmplex - a MODBUS/TCP multiplexer
There are some MODBUS/TCP slave implementations around in this world with a limitation to serve only one concurrent master. Multiple masters accessing such a slave implementation causes all kind of havoc, from aborted TCP connections to packet loss and transmission errors. Modbusmplex is a MODBUS multiplexer that provides a way to work around such a limitation by multiplexing multiple MODBUS/TCP master connections into one MODBUS/TCP connection towards a slave. ... -

PJON
Experimental, arduino-compatible, multi-master, multi-media network
PJON® (Padded Jittering Operative Network) is an experimental, Arduino-compatible, multi-master, multi-media, software-defined network protocol that can be easily cross-compiled on many microcontrollers and real-time operative systems like ATtiny, ATmega, SAMD, ESP8266, ESP32, STM32, Teensy, Raspberry Pi, Zephyr, Linux, Windows x86, Apple and Android. PJON operates on a wide range of media, data links and existing protocols like PJDL, PJDLR, PJDLS, Serial, RS485, USB, ASK/FSK, LoRa, UDP, TCP, MQTT and ESPNOW. PJON is an experimental network protocol stack crafted in 10 years of research and experimentation. It was originally developed as an open-source alternative to i2c and 1-Wire but during development, its scope and features have been extended to cover use cases where IP is generally applied. PJON has been engineered to have a variable footprint (4.2-8.2 kB program memory) and overhead (5-35 bytes per packet) depending on its configuration.
