802.1 WG - Higher Layer LAN Protocols Working Group

Glenn Parsons

This standard specifies how all or part of a network can be secured transparently to peer protocol entities that use the MAC Service provided by IEEE 802? LANs to communicate. MAC security (MACsec) provides connectionless user data confidentiality, frame data integrity, and data origin authenticity.

This amendment to IEEE Std 802.1Q-2011 specifies shortest path bridging of unicast and multicast frames, including protocols to calculate multiple active topologies that can share learned station information, and support of a virtual local area network (VLAN) by multiple, per topology VLAN identifiers (VIDs).

The MAC service provided by all IEEE 802(R) MACs along with the Internal Sublayer Service (ISS) that is provided by IEEE 802 MACs to the relay function of a Media Access Control(MAC) Bridge are defined in this standard.

This standard provides an overview to the family of IEEE 802? standards. It describes the reference models for the IEEE 802 standards and explains the relationship of these standards to the higher layer protocols; it provides a standard for the structure of IEEE 802 MAC addresses; it provides a standard for identification of public, private, prototype, and standard protocols; it specifies an object identifier hierarchy used within IEEE 802 for uniform allocation of object identifiers used in IEEE 802 standards; and it specifies a method for higher layer protocol identification.

Link Aggregation allows one or more links to be aggregated together to form a Link Aggregation Group, such that a Media Access Control (MAC) Client can treat the Link Aggregation Group as if it were a single link. To this end, it specifies the establishment of data terminal equipment (DTE) to DTE logical links, consisting of N parallel instances of full-duplex, point-to-point links operating at the same data rate. The MAC independent Link Aggregation capability, and general information relevant to specific MAC types that support Link Aggregation, are defined in this standard.
