AES Standards data references – AES Standards, registered values

Organisationally-Unique Identifier (OUI)

Organisationally-Unique Identifiers are registered with the IEEE Registration Authority for use Local and Metropolitan Area Network applications. They can be used to generate LAN MAC addresses and protocol identifiers. For more information, see ISO/IEC 8802, IEEE 802.3, and the IEEE Registration Authority Web site.

An OUI comprises a 3-octet value:

AES OUI00-0B-5E

Unauthorised use of the AES OUI is prohibited.

AES OUI applications

It is important that the various uses of the AES OUI do not conflict. If you are drafting an AES document that requires an OUI, please contact the AES standards manager to obtain authorisation. Current applications include:

AES47ATM signalling: BHLI IE
AES51Ethernet packet addressing: multicast MAC address
AES67AES profile: High-performance streaming audio-over-IP interoperability

EtherType

Ethernet Type Field values (“EtherTypes”) are registered with the IEEE Registration Authority and provide a context for interpretation of the data field of an Ethernet frame (protocol identification). For more information, see IEEE 802.3-1998 3.2.6 and the IEEE Registration Authority Web site.

An EtherType comprises a 2-octet value:

AES Ethertype88DD16

Unauthorised use of the AES EtherType is prohibited.

In any Ethernet packet using the AES EtherType value, the first octet of the MAC client data will be an AES Protocol Identifier and the remainder of the MAC client data will conform to the standard indicated in the table below.

AES47ATM signalling: BHLI IE
AES51Ethernet packet addressing: multicast MAC address
AES67AES profile: High-performance streaming audio-over-IP interoperability

AES Protocol Identifiers

Current protocol identifiers, assigned by the AES standards secretariat for specific standards and development projects, include:

0016reserved
0116AES50-2005 (HRMAI)
0216AES51-2006 AES Ethernet (ATM-E) protocol identifier
0316reserved for project AES-X182
0416 to FE16reserved pending assignment by AES standards secretariat
FF16reserved

An EtherType comprises a 2-octet value:

AES Ethertype88DD16

Unauthorised use of the AES EtherType is prohibited.

In any Ethernet packet using the AES EtherType value, the first octet of the MAC client data will be an AES Protocol Identifier and the remainder of the MAC client data will conform to the standard indicated in the table below.

AES47ATM signalling: BHLI IE
