Ethernet is one of the most common computer-networking components, and the standardization of this technology has created some of the easiest ways to connect a few computers with or without wires. There's a good chance you're using it right now. Find out what Ethernet is and how it creates a computer network.
For Ethernet, the IEEE 802.2 standard describes the LLC sublayer functions, and the 802.3 standard describes the MAC sublayer and the Physical layer functions. Logical Link Control handles the communication between the upper layers and the networking software, and the lower layers, typically the hardware. LLC can use a number of LAN (and MAN/WAN?) protocols as its transport protocol: Ethernet: LLC can be used for packets on Ethernet networks, although many protocols don't use it when running atop Ethernet. IEEE_802.11: LLC is used for data packets on IEEE_802.11 networks. FDDI: LLC is used for data packets on FDDI networks. Ethernet Delivery - Our services are delivered traditional Ethernet so no special equipment is necessary to connect to existing LAN. The FiberAir Advantage - Discover the FiberAir difference and experience a new stream of productivity. May 20, 2020 · An Ethernet frame can be no shorter than 64 bytes, and no longer than 1518 bytes in total length. The 802.2 Logical Link Control Header (LLC) Following the Data Link Header is the Logical Link Control Header, which is described in the IEEE 802.2 Specification. The SharkTap is a special purpose 10/100Base-T ethernet switch that allows you to 'tap into' an ethernet connection. It is intended to be used with the open source Wireshark network analyzer or equivalent. Conventional switches route packets only to the intended destination port, reducing traffic, but preventing a third port from seeing all
Following the address fields, IEEE 802.3 Ethernet uses a 2-byte "length" field that includes the IEEE 802.2 Logical Link Control (LLC) bytes and the data bytes. The length field in IEEE 802.3 Ethernet frames is always less than hex '05DC'. This corresponds to 1500 bytes which is the maximum frame size for Ethernet.

In fact, most frames do not have an LLC header, since most frames today are transporting IPv4/IPv6 via ETHERNET II header. 802.3 does have an LLC header though. The different frame formats are indicated by the preceding start frame delimiter (Preamble) which ends in "11" instead of "10" for 802.3 formatted frames.

The length field in IEEE 802.3 Ethernet frames is always less than hex '05DC'. This corresponds to 1500 bytes which is the maximum frame size for Ethernet. Webinar: Interoperability and the Ethernet Ecosystem. Interoperability and the Ethernet Ecosystem webinar panelists will discuss the multivendor integration showcasing a live 400 GbE switch fabric, an implementation of Flex Ethernet (FlexE), 100Gb/s per lane over a direct attach cable (DAC) and analysis of PAM4 signaling, and a broad array of the latest Ethernet products and solutions. Aug 18, 2011 · Logical Link Control (LLC) is one of two Data Link Layer (DLL) network protocol sublayers within the Open System Interconnection (OSI) data communication model. LLC is located in the upper DLL area of OSI Layer 2 above the Physical Layer (PHY) of OSI Layer 1. LLC is standardized as IEEE 802.2 by the Institute of Electrical and Electronics The 802.2 Logical Link Control (LLC) Information-----The IEEE 802.3 Ethernet specification was intended to be used with the 802.2 Logical Link Control (LLC) specification. The LLC information envelops the data of the frame, and the 802.3 headers envelop this 802.2 LLC protocol data unit (PDU). This is the frame structure for an 802.3 Ethernet
