The LLC layer is an IEEE mechanism for identifying the data carried in an Ethernet frame. The MAC layer defines the protocol used to arbitrate access to the Ethernet system. Both of these systems are described in detail in Chapter 3 .

Our service is unmatched. Excellent performance, fast delivery and the most competitive prices in the market place Ethernet Extender is a concept and term that Enable-IT invented, branded and coined in the 90’s. Designed to transparently drive long distance Ethernet beyond the IEEE 802.3 specifications for today’s twisted pair wiring distance limitation of 328 feet or 100 meters, creating very cost-effective, bridged Ethernet connections. LLC: BACnet Ethernet uses LLC atop Ethernet as its transport protocol, and BACnet ARCNET uses LLC atop ARCNET as its transport protocol. For BACnet traffic, DSAP is 0x82, SSAP is 0x82. MSTP: BACnet MS/TP uses either MSTP natively, or from the Cimetrics U+4 converter, LLC SNAP as its transport protocol. Example traffic. Wireshark

An Ethernet frame can be no shorter than 64 bytes total length and no longer than 1518 bytes total length. THE 802.2 LOGICAL LINK CONTROL (LLC) HEADER . Following the Datalink Header is the Logical Link Control (LLC) Header, which is described in the IEEE 802.2 Specification. Jul 16, 2012 · For example, Ethernet, Token Ring, FDDI and 802.11 ("wireless Ethernet" or "Wi-Fi') are all sometimes called "data link layer technologies". The set of devices connected at the data link layer is Global Provider Ethernet LEADERBOARD: AT&T, Colt, CenturyLink, Verizon Challenge Tier: SingTel, T-Systems, Tata, Telefonica, Vodafone. Detailed Ethernet share results that power the Year-End 2018 Global Provider Ethernet LEADERBOARD are available nowexclusively through Vertical Systems Group’s ENS Research Program subscribers of @Ethernet.

Ethernet II frame, or Ethernet Version 2, or DIX frame is the most common type in use today, as it is often used directly by the Internet Protocol. Novell raw IEEE 802.3 non-standard variation frame; IEEE 802.2 Logical Link Control (LLC) frame; IEEE 802.2 Subnetwork Access Protocol (SNAP) frame

When transmitting data over Ethernet, the Ethernet frame is primarily responsible for the correct rulemaking and successful transmission of data packets. Essentially, data sent over Ethernet is carried by the frame. An Ethernet frame is between 64 bytes and 1,518 bytes big, depending on the size of the data to be transported. 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.
