N1	Ethernet and switching

This course covers both 802.3 (10, 100, 1000 Mbps) and 802.1P/802.1Q

Objectives The course explains the IEEE802.3 specification, and especially the evolution between Ethernet 10Mbps, 100Mbps, 1000Mbps and 10 Gbps. An architectural view of an Ethernet network is provided, highlighting the differences between repeaters, switches and routers. The MAC layer is studied through various Freescale implementation examples. The course explains how the spanning tree algorithm works. Quality of Service through the VLAN tag is explained. Switch related protocols are detailed, especially IGMP snooping. The course details the operation of the PHY-to-MAC bus. The course describes the transmission protocol according to the medium. An introduction to TCP-UDP/IP allows to understand how upper layer data are encapsulated into Ethernet frames. This course has been delivered several times to companies implementing Ethernet in embedded systems, such as missiles, railway equipments and avionics systems A more detailed course description is available on request at info@ac6-formation.com
