Full title and description

ISO/IEC/IEEE 8802-1AC:2018 — Information technology — Telecommunications and information exchange between systems — Local and metropolitan area networks — Part 1AC: Media access control (MAC) service definition. This international joint standard defines the MAC Service and the Internal Sublayer Service (ISS) and specifies the media-dependent convergence functions that map IEEE 802 MAC interfaces to the ISS.

Abstract

The standard defines the Media Access Control (MAC) Service and the Internal Sublayer Service (ISS), and specifies the media-dependent convergence functions required to map IEEE 802 MAC interfaces to the ISS. It provides the formal service definitions used by higher-layer protocols and by IEEE 802 family MACs.

Scope

This part (1AC) of the ISO/IEC/IEEE 8802 family defines the MAC Service and the Internal Sublayer Service (ISS) and specifies the media-dependent convergence functions that map IEEE 802 MAC interfaces to the ISS. It is intended to provide a consistent service definition so that different IEEE 802 MACs and higher-layer protocols can interoperate using a common service model. The standard has been maintained with a corrigendum and an amendment to cover updates such as LLC encapsulation EtherType corrections and support for additional MAC entities.

Key topics and requirements

• Formal definition of MAC Service primitives and behavior for use by higher-layer protocols.
• Definition of the Internal Sublayer Service (ISS) used to abstract MAC entities.
• Specification of media-dependent convergence functions mapping IEEE 802 MAC interfaces to the ISS.
• Support and accommodation for multiple IEEE 802 MAC families (amendment adds support for IEEE 802.15.3 MAC entity).
• Corrections for LLC encapsulation EtherType provided via corrigendum.

Typical use and users

Primary users include standards engineers, network-equipment vendors (switches, NICs, wireless MAC implementations), firmware and device driver developers, conformance and test laboratories, and researchers designing or validating MAC-layer behavior and higher-layer protocols that rely on a stable MAC service model.

Related standards

Closely related parts of the 8802/802 family and other IEEE/ISO/IEC documents include other 8802-1 parts (for bridging, VLANs, timing and synchronization, MAC security, etc.), IEEE 802.1AE (MACsec / MAC security), IEEE 802.1Q (bridging and VLAN tagging), and standards describing specific MAC/PHY families such as IEEE 802.15.3 (support for which was added via amendment). The document is part of the broader suite of LAN/MAN standards used together for complete networking solutions.

FAQ

Q: What is this standard?

A: ISO/IEC/IEEE 8802-1AC:2018 is the international joint standard that defines the Media Access Control (MAC) Service and the Internal Sublayer Service (ISS) for IEEE 802 local and metropolitan area networks, and specifies how IEEE 802 MAC interfaces map to the ISS.

Q: What does it cover?

A: It covers the formal MAC Service primitives and behavior, the ISS definition, and the media-dependent convergence functions needed so different IEEE 802 MACs and higher-layer protocols can use a consistent service model. The standard has a corrigendum addressing LLC EtherType and an amendment adding support for additional MAC entities.

Q: Who typically uses it?

A: Network equipment manufacturers, firmware and driver developers, standards engineers, test and certification labs, and researchers who implement or verify MAC-level behavior and higher-layer protocol interactions.

Q: Is it current or superseded?

A: The 2018 edition is the published edition and has been maintained with a 2020 corrigendum and a 2023 amendment; it remained current upon ISO review. Check with the issuing organizations for any newer revisions or additional amendments before procurement or design.

Q: Is it part of a series?

A: Yes — it is one part (1AC) of the ISO/IEC/IEEE 8802 (IEEE 802) family of standards covering LAN/MAN technologies; other parts specify bridging, timing, security, and other MAC/PHY services.

Q: What are the key keywords?

A: MAC Service, ISS, IEEE 802, media-dependent convergence, LLC, EtherType, LAN, MAN, MAC definition.
