TNnett

TNnett is a term used in discussions of computer networking to describe a proposed transport-layer approach intended to enable low-latency, reliable data delivery for distributed applications. The name combines a reference to transport networking with the suffix nett, and in published materials it is typically presented as a concept rather than a formal standard.

Overview: TNnett is described as a lightweight protocol stack that can operate on top of existing IP networks while exposing application-level cues to guide routing, flow control, and recovery. Proponents emphasize small control messages, data chunking, and selective acknowledgments to reduce head-of-line blocking and retransmission delays. In theory, TNnett aims to complement traditional transport protocols by offering predictable latency for time-sensitive workloads.

Architecture and features: Core ideas include a modular transport core, per-flow state management, and optional path-selection logic that can prioritize low-latency routes. It supports out-of-order delivery and in-order reassembly at the receiver, with adaptive congestion control that can react to deadlines or quality-of-service requirements. Security considerations typically involve end-to-end encryption and authenticated signaling between endpoints.

Status and usage: There is no formal standard for TNnett. It remains primarily a topic in academic papers and experimental or reference implementations rather than widespread production use. Reported use cases in the literature include real-time analytics, edge computing, Internet of Things backhaul, and multiplayer gaming scenarios where conventional protocols either add too much latency or fail to meet reliability needs.
