TCPIPhin
TCPIPhin is a fictional protocol framework proposed to augment the traditional TCP/IP stack with a modular, transaction-oriented processing layer. The name pairs TCP/IP with “Phin,” a notional phase-based engine intended to handle session state, flow control, and extensibility. In this concept, TCPIPhin resides between the IP layer and high-level application protocols, offering reliable transport while exposing programmable hooks for codecs, security, and policy enforcement.
Architecture of TCPIPhin defines a core transport module that provides reliable, in-order delivery and congestion control;
Operation and features emphasize a capability-driven startup where endpoints declare supported features during a capability exchange
Development status and usage indicate that TCPIPhin exists as a theoretical concept found in academic discussions
