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.
With ISL, an Ethernet frame is encapsulated with a header that transports VLAN IDs between switches and routers. With IEEE 802.1Q the tag is internal. This is a key advantage for IEEE 802.1Q as it means tagged frames can be sent over standard Ethernet links. ISL does add overhead to the frame as a 26-byte header containing a 10-bit VLAN ID.
Multiple MAC Registration Protocol is a data link layer (layer 2) protocol to register group MAC addresses (i.e. multicast) on multiple switches. It is an MRP application, originally defined in IEEE 802.1ak-2007 and subsequently included in 802.1Q. It replaced the 802.1D-based GMRP.
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards.
Wireless network cards for computers require control software to make them function (firmware, device drivers). This is a list of the status of some open-source drivers for 802.11 wireless network cards. Location of the network device drivers in a simplified structure of the Linux kernel.
In contrast to standard Ethernet according to IEEE 802.3 and Ethernet bridging according to IEEE 802.1Q, time is very important in TSN networks.For real-time communication with hard, non-negotiable time boundaries for end-to-end transmission latencies, all devices in this network need to have a common time reference and therefore, need to synchronize their clocks among each other.
The company championed the technology and brought it to the IEEE 802.1 committee where it was renamed to PBB-TE and a working group, P802.1Qay, was chartered on May 7, 2007. [5] 802.1Qay was in sponsor ballot from January 2009 [6] to April 2009. [7] It was ratified by the IEEE Standards Association on June 18, 2009. [1] It was published in ...
IEEE 802.1 is a working group of the IEEE 802 project of the IEEE Standards Association.. It is concerned with: [1] 802 LAN/MAN architecture; internetworking among 802 LANs, MANs and wide area networks
