TCP/IP Protocol stack

tcp/ip protocol stack implememtation with golang for learning purpose

A user-space TCP protocol stack implemented in modern C++17 over UDP, featuring connection management, reliable transfer, flow control, and a simplified RFC 6582 NewReno congestion control.

SoftTCPStack is an open-source, software-implemented TCP/IP stack designed for educational and experimental purposes. This project aims to provide a simple yet functional implementation of the TCP/IP protocol suite, entirely in software, to facilitate a deeper understanding of network protocols and their interactions.

Unified neural infrastructure for the next-generation internet. A programmable, protocol-agnostic, distributed execution layer combining ENTENCY UP and GNS.

Audio Transmission Control Protocol

This paper is a state-of-the-art review of the implementation, challenges, and future opportunities of quantum internet networks.

DTP-Ω1 (Divinitus Transmission Protocol) is a layered, stateful, checksum-verified communication standard designed for sanctified data transfer across Mechanicus-aligned systems, cogitator units, and blessed network links. It ensures purity, order, and compliance in all transmissions.
