IEEE specification for Precision Time Protocol (PTP).

A family of IEEE Local Area Network (LAN) standards. The services and protocols specified by the 802 standards map to Layer 1 (L1) and Layer 2 (L2) of the Open Systems Interconnection (OSI) Reference Model:

IEEE specification for Link Layer Discovery Protocol (LLDP).

Amendment to IEEE 802.1Q for Provider Bridging (PB).

Amendment to IEEE 802.1Q for Connectivity Fault Management (CFM).

IEEE specification that adds Provider Backbone Bridging (PBB) to 802.1ad Provider Bridging (PB):

Amendment to IEEE 802.1Q for Multiple Registration Protocol (MRP).

Amendment to IEEE 802.1D for Shortest Path Bridging (SPB).

IEEE specification for link aggregation and Multi-Chassis Link Aggregation (MLAG).

IEEE specification which allows multiple LANs to be connected together through what the standard calls a “MAC bridge” which filters data sent between LAN segments, allowing networks to be partitioned for administrative purposes and reducing network congestion. The more common term for a MAC bridge is switch. The 802.1D standard includes Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP).

IEEE 802.1Q defines priority signaling for traffic that can be used by Quality of Service (QoS) mechanisms to differentiate traffic. Packets are tagged as belonging to a queue, which determines the priority of the packet. Although this technique is often called “802.1p”, there is no standard by that name. Instead, the technique is incorporated into 802.1Q standard.

IEEE Virtual Local Area Network (VLAN) and Multiple Spanning Tree Protocol (MSTP) specifications. This standard refers to VLANs as “virtual bridged networks”. The 802.1D standard covers “VLAN-unaware” switches, while 802.1Q extends 802.1D for “VLAN-aware” switches.

Amendment to IEEE 802.1Q for Quantized Congestion Notification (QCN).

Amendment to IEEE 802.1Q for Provider Backbone Bridge-Traffic Engineering (PBB-TE).

Amendment to IEEE 802.1Q for Data Center Bridging Capability Exchange (DCBX) and Enhanced Transmission Selection (ETS).

Amendment to IEEE 802.1Q for Priority-based Flow Control (PFC).

Amendment to IEEE 802.1Q for Edge Virtual Bridging (EVB).

Amendment to IEEE 802.1Q to classify incoming packets based on data link layer protocol identification.

IEEE specification for Ethernet to the First Mile (EFM).

IEEE specification for flow control.

ITU-T specification for Ethernet Linear Protection Switching (ELPS).

ITU-T specification for Ethernet Ring Protection Switching (ERPS).
