IEEE 802.1ad is an amendment to the IEEE 802.1Q-1998 networking standard which adds support for provider bridges. It was incorporated into the base 802.1Q standard in 2011. The technique specified by the standard is known informally as stacked VLANs or QinQ.
IEEE 802.1 is a working group of the IEEE 802 project of the IEEE Standards Association. It is concerned with: 802 LAN/MAN architecture; internetworking among 802 LANs, MANs and wide area networks; 802 Link Security; 802 overall network management; protocol layers above the MAC and LLC layers; LAN/MAN bridging and management.

IEEE 802.1ad ist eine Änderung des Netzstandards IEEE 802.1Q-1998, mit der die Unterstützung für Provider-Bridges hinzugefügt wird. Sie wurde 2011 in den Basisstandard 802.1Q aufgenommen. Die in der Norm spezifizierte Technik ist informell als gestapelte VLANs oder QinQ bekannt.
IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames.
