but is not identical to the maximum frame size that can be transported on the data link layer, e.g., Ethernet frame. Larger MTU is associated with reduced...

jumbo frames. Each Ethernet frame must be processed as it passes through the network. Processing the contents of a single large frame is preferable to processing...

is a two-octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving...

Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared...

catches up. Flow control on Ethernet can be implemented at the data link layer. The first flow control mechanism, the pause frame, was defined by the Institute...

This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Within the Open Systems Interconnection (OSI) network...

RoCE v1 protocol is an Ethernet link layer protocol with Ethertype 0x8915. This means that the frame length limits of the Ethernet protocol apply: 1500...

VLAN tag changes the frame, 802.1Q encapsulation forces a recalculation of the original frame check sequence field in the Ethernet trailer. The IEEE 802...

networking, Fast Ethernet physical layers carry traffic at the nominal rate of 100 Mbit/s. The prior Ethernet speed was 10 Mbit/s. Of the Fast Ethernet physical...

Terabit Ethernet (TbE) is Ethernet with speeds above 100 Gigabit Ethernet. The 400 Gigabit Ethernet (400G, 400GbE) and 200 Gigabit Ethernet (200G, 200GbE)...

The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers...

Ethernet frame. Each frame contains one LLDP Data Unit (LLDPDU). Each LLDPDU is a sequence of type–length–value (TLV) structures. The Ethernet frame used...

Ethernet II encapsulation comprises an Ethernet II frame header (destination MAC, source MAC, EtherType 0x8137) followed by IPX data. In non-Ethernet...

memory (CAM) is initially empty. For each received Ethernet frame the switch learns from the frame's source MAC address and adds this together with an...

Industrial Ethernet (IE) is the use of Ethernet in an industrial environment with protocols that provide determinism and real-time control. Protocols for...

allow PTP to apply beyond wired Ethernet networks. To account for data path delays, the gPTP protocol measures the frame residence time within each bridge...

40 Gigabit Ethernet (40GbE) and 100 Gigabit Ethernet (100GbE) are groups of computer networking technologies for transmitting Ethernet frames at rates...
