LAN Overview
Technologies
Gigabit & 10 Gigabit Ethernet
Fibre Channel
High Speed Wireless LANs
Applications requiring High Speed LANs
Centralised server farms : user needs to draw huge amounts of data from mulple centralised
servers
Power workgroups
Small number of cooperating users : draw massive data files across network
High-speed local backbone
Processing demand grows
LANs proliferate at site
High-speed interconnecon is necessary
Hierarchical Network Design
LAN Architecture Evolution
Topologies
Bus and Tree
Characterised by the use of mulpoint
Transmission propagates throughout medium
Heard by all staons
Head -end connected to branching cables
Ring
