Chapter 5 - Data-link layer protocols. Chapter summary: Supports multiple cable types and speeds, uses the CSMA/CD MAC mechanism to detect collisions, uses a logical ring topology, uses the token passing MAC mechanism, uses a double ring or star topology, uses the token passing MAC mechanism, runs at speeds up to 11 Mbps, uses the CSMA/CA MAC mechanism. | Chapter Overview Ethernet Token Ring FDDI Wireless Networking Ethernet Standards Ethernet is the most popular local area network (LAN) protocol operating at the data-link layer. There are two sets of Ethernet standards: DIX Ethernet Institute of Electrical and Electronic Engineers (IEEE) DIX Ethernet Standards DIX Ethernet. Also known as thick Ethernet, ThickNet, or 10Base5 DIX Ethernet II. Retains 10Base5 and adds 10Base2 (thin Ethernet) IEEE Standards IEEE . 10Base5, 10Base2, and 10Base-T IEEE . Fast Ethernet IEEE and IEEE . Gigabit Ethernet DIX Ethernet/IEEE Components Physical layer specifications Frame format CSMA/CD MAC mechanism Standard 10-Mbps Ethernet Specifications Designation Cable Type Topology Maximum Length 10Base5 RG-8 coaxial Bus 500 meters 10Base2 RG-58 coaxial Bus 185 meters 10Base-T Category 3 UTP Star 100 meters Fiber Optic Inter-Repeater Link (FOIRL) Multimode fiber optic Star 1,000 meters 10Base-F . | Chapter Overview Ethernet Token Ring FDDI Wireless Networking Ethernet Standards Ethernet is the most popular local area network (LAN) protocol operating at the data-link layer.
