The concept of this document considers the FNQoS related to the FNProxy based in ISO/IEC TR 29181-8. The protocol mechanism given in this document supports both the interaction between two FNProxies of a basic FNQoS system (BFS) and the interaction among multiple FNProxies in a synthetic FNQoS system (SFS).

Overview

ISO/IEC 21559-2:2023 - "Telecommunications and information exchange between systems - Future network protocols and mechanisms - Part 2: Proxy model‑based quality of service" describes a proxy‑model approach to Quality of Service (FNQoS) for Future Network (FN) environments. The standard defines protocol mechanisms that enable synchronous interactions between intelligent proxies (FNProxies), supporting both a two‑proxy Basic FNQoS System (BFS) and multi‑proxy Synthetic FNQoS System (SFS). It complements ISO/IEC 21558‑2 and relates to ISO/IEC TR 29181‑8.

Key technical topics and requirements

FNProxy concept and engines: Specifies three core engines inside an FNProxy - perception, negotiation and execution - to support autonomous, harmonized QoS behavior.

Interaction models: Defines Bi‑directional Service (Bi‑S) interactions for both pairwise (BFS) and multi‑proxy (SFS) configurations.

Data and protocol units:

FPDU (FNProxy Protocol Data Unit) - the data unit exchanged between FNProxies.
BFSP / SFSP - protocol definitions and message semantics/timing for BFS and SFS respectively.

Topology and linking:

FIB (FNProxy Interaction Bridge) - logical linking paths for proxy interactions in an SFS.
FLM (FNProxy Link Mode) - link templates to standardize linking, negotiation and transition behavior; Annex D lists example FLMs.

Strategies and procedures:

FNProxy Strategy (FNPS) and FSB (FNProxy Strategy Base) - predefined response sets and storage for strategy schemes.
Service transition rules and conditions for when an FNProxy must hand off requirements it cannot serve.

Protocol behavior and modeling:

UML usage for system modeling, sequence diagrams for SFS procedures, and procedures described as ordered interactions.

Supplementary material: Informative annexes include quantitative harmonization methods, C++ Bi‑S examples, methods for domains, and guidance to avoid infinite transitions.

Note: the standard calls out possible patent claims and recommends use of Artificial Intelligence Enabled Networking (AIEN) for FN development.

Practical applications and who uses it

Network architects and engineers designing Future Network QoS frameworks that rely on autonomous, proxy‑based coordination.

Vendors building FNProxy software/hardware implementing perception, negotiation and execution engines.

System integrators and service providers who need standardized mechanisms for inter‑proxy QoS negotiation, service transition and multi‑domain coordination.

Researchers and developers working on AIEN, semantic networking, and advanced QoS harmonization strategies.

Standards bodies and implementers who need interoperable FPDU/BFSP/SFSP definitions and examples (including Annex B C++ sample).
