1 Key Technologies (cont.)
  • switches - second generation of bridges; hybrid switch routers; low cost; high performance; used for wiring closets and also central campus hubs
  • Virtual LANs - require sophisticated hardware and software; essential component of future high-performance networks
  • Advanced Network Management - necessary but very expensive; SNMP /RMON; difficult to implement; management with limited success
2 High-Speed Network Technology (most strategically important)
  • ATM - high speed, guaranteed bandwidth, superior price/performance; immature, complexity, lack of standards
  • FDDI and switched FDDI - backbone technology based on token passing, high speed, firmly established standards, very robust, long distances; rather expensive
