IEEE 802.1Q, also known as Dot1q, is a standard that supports virtual local area networking (VLANs) on Ethernet networks. It adds a 32-bit tag to the frames to indicate the VLAN membership and priority level, and defines procedures for bridges and switches to handle tagged frames.
An Ethernet frame is a data link layer protocol data unit that carries payload data and other headers. The payload data is preceded by a preamble, a start frame delimiter, a destination MAC address, a source MAC address, an EtherType or length field, and an optional tag.
The physical layer of Ethernet is the lowest layer of the network protocol stack that defines the electrical or optical properties and the transfer speed of the connection between devices. Learn about the history, standards, media types, and naming conventions of Ethernet physical layer.
EtherNet/IP is an industrial network protocol that adapts the Common Industrial Protocol (CIP) to standard Ethernet. It is widely used in the United States and supports various Ethernet standards and services for real-time control applications.
Terabit Ethernet (TbE) is Ethernet with speeds above 100 Gigabit Ethernet. Learn about the development, specifications and applications of TbE, from 400 Gbit/s to 1.6 Tbit/s, and the companies and organizations involved in its research and deployment.
Data center bridging (DCB) is a set of enhancements to Ethernet for data center environments, such as clustering and storage networks. Learn about the motivation, approach, terminology and standards of DCB, as well as related protocols such as TRILL and SPB.
IEEE 802.1ad is a networking standard that allows multiple VLAN tags to be inserted into an Ethernet frame, known as QinQ or stacked VLANs. It is used for metro Ethernet and provider bridges, and has a different EtherType for the outer tag (0x88A8).
