1. Introduction to the Gigabit-Ethernet by Yun Qi Source : http://www.mcinfo.com Rivier College, CS699 Professional Seminar

2. What is Gigabit Ethernet u Gigabit Ethernet is an extension to the 10 and 100 Mbps IEEE 802.3 standards. u Gigabit Ethernet is a connectionless protocol that each Ethernet frame contains a destination address, and is routed through the network.

3. Gigabit Ethernet System Layers u Physical Layer - 1000Base-X - 1000Base-T u MAC Layer - Carrier Extension - Packet Bursting

4. Gigabit Media Independent Interface (GMII) Gigabit Ethernet Protocol Architecture

5. GMII (continued) u The GMII is divided into three sublayers: - PCS (Physical Coding Sublayer) - PMA (Physical Medium Attachment) - PMD (Physical Medium Dependent)

6. Gigabit Ethernet Migration Gigabit Ethernet LAN

7. Topologies u Upgrading server-switch connection. u Upgrading switch-switch connection. u Upgrading a fast Ethernet backbone. u Upgrading a shared FDDI backbone. u Upgrading high performance workstations.
