IEEE 802.1Q. 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.
Artur Phleps (29 November 1881 – 21 September 1944) was an Austro-Hungarian, Romanian and Nazi officer who was an SS-Obergruppenführer und General der Waffen-SS in the Waffen-SS during World War II. He was an Austro-Hungarian Army officer before and during World War I. During the interwar period, he joined the Romanian Army and became an ...
Ethernet packet. The SFD (start frame delimiter) marks the end of the packet preamble. It is immediately followed by the Ethernet frame, which starts with the destination MAC address. [1] In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport
Terabit Ethernet (TbE) is Ethernet with speeds above 100 Gigabit Ethernet. The 400 Gigabit Ethernet (400G, 400GbE) and 200 Gigabit Ethernet (200G, 200GbE) [ 1 ] standard developed by the IEEE P802.3bs Task Force using broadly similar technology to 100 Gigabit Ethernet [ 2 ][ 3 ] was approved on December 6, 2017. [ 4 ][ 5 ] On February 16, 2024 ...
The Ethernet physical layer has evolved over its existence starting in 1980 and encompasses multiple physical media interfaces and several orders of magnitude of speed from 1 Mbit/s to 400 Gbit/s. The physical medium ranges from bulky coaxial cable to twisted pair and optical fiber with a standardized reach of up to 80 km.
EtherNet/IP is one of the leading industrial protocols in the United States and is widely used in a range of industries including factory, hybrid and process. The EtherNet/IP and CIP technologies are managed by ODVA, Inc., a global trade and standards development organization founded in 1995 with over 300 corporate members.
Data Center Ethernet (DCE) was a term trademarked by Brocade Communications Systems in 2007 but abandoned by request in 2008. [3] DCE referred to Ethernet enhancements for the Data Center Bridging standards, and also including a Layer 2 Multipathing implementation based on the IETF's Transparent Interconnection of Lots of Links (TRILL) standard.
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. [1] The technique specified by the standard is known informally as stacked VLANs or QinQ. The original 802.1Q specification allows a single virtual local area network (VLAN ...
