Local Area Network Architectures

  • Identify the LAN architectures in place.
  • Is the company running a standard LAN architecture at all sites or do they vary?
  • Examples: Ethernet, FIDDI, Token Ring, 802.11 etc.
  • Note the bandwidth on each LAN site.
  • Identify the network media in place. Examples: Fiber Optic, Unshielded Twisted Pair Copper, Wireless, Satellite.

Wide Area Network Architectures

  • Identify the WAN technologies used to interconnect your company‚Äôs Local Area Networks.
  • Examples: 10 Gigabit Ethernet, T1 Carrier Family, Frame Relay, X.25, SONET, ISDN, Asynchronous Transfer Mode (ATM).
  • Develop a diagram that shows the WAN interconnection of all LAN sites company wide.
