This document describes the architectural aspects of Future Network (FN) Quality of Service (QoS) based on an FNProxy model, taking into account the requirements described on ISO/IEC TR 29181-8. It describes: — the concept of future network QoS (FNQoS), — the architectural model of FNQoS system, — the usage of FNQoS system.

Overview

ISO/IEC 21558-2:2023 - "Telecommunications and information exchange between systems - Future network architecture - Part 2: Proxy model-based quality of service" specifies the architectural aspects of Future Network Quality of Service (FNQoS) using an FNProxy (proxy) model. It defines the FNQoS concept, a reference architectural model for an FNQoS system, and usage scenarios (including human-centric use, inter-FNQoS interaction and inter-working with legacy networks). The document takes into account requirements from ISO/IEC TR 29181-8 and complements protocol mechanisms described in related parts (e.g., ISO/IEC 21559-2).

Key topics and technical requirements

FNProxy model: Defines software or device elements (FNProxies) that both provide service and request services in an FNQoS system.

Three engines inside an FNProxy:

Perception engine - senses requirements and environmental changes.
Negotiation engine - matches perceived needs to capabilities and signs service contracts or forwards requests.
Execution engine - enforces contracts and may generate further requirements.

Bidirectional Service (Bi-S): A core interaction reference point enabling concurrent, synchronized, bidirectional exchanges between FNProxies; treated as an operator for interaction semantics and harmony measurement.

FNQoS system modes: Distributed mode (FNQoS functions distributed across FNProxies) and central mode (centralized FNQoS information system).

Harmony relations:

FHR (FNProxy Harmony Relation) for pairwise interaction assessment.
MFHR (Multiple FNProxies Harmony Relation) for composed interactions among three or more FNProxies.

Architectural constructs: FNProxy interfaces, domains (functional classification), engines, and a reference model for system composition and interoperation.

Operational concerns: Negotiation, binding, registration and administration of FNProxies; applicability to AI-enabled networking (AIEN) and evolution paths for FNQoS.

Applications and who should use this standard

Telecommunications architects and network engineers designing future network architectures and QoS systems.

Vendors and integrators building AI-enabled networking (AIEN) components or proxy-based QoS services.

Protocol designers and system implementers developing Bi‑S interaction mechanisms and FNProxy engines.

Research groups and standardization bodies working on next-generation QoS, interoperability, and migration strategies for legacy networks.

Solution owners needing a reference architecture for distributed vs. centralized FNQoS deployments.
