Networking Fundamentals​, Quick Notes – Wide Area Networks Part 2

SOHO Router

SOHO Router, wired & wireless devices

  • Small Office Home Office or Residential/Home Router, a.k.a Residential or Home Router.
  • Simple “Network address translation (NAT)” device with facilities such as an Unmanaged Network Switch + Access Point + DSL Modem + SIM Ports + USB Ports…
  • Simple & easy to Use, requires almost no technical experience.
  • Usually administered through a web interface.
  • Widely used in Home & Small Office Networks mostly for sharing Internet Connectivity.

 

Wireless Router

4G Router

 

Tip(s):

  • Wired networks can be extended by using a Network switch or a SOHO Router (as long as SOHO Router has sufficient network connectivity ports).
  • Wireless networks can be extended using a range extender (some models of access points & Wi-Fi Routers may have the option to work as a range extender).

VPN

  • Virtual Private Network refers to private networks across public network.
  • A special virtual “Tunnel” created between end-points.
  • Typically used for connecting to office networks from remote locations, over Internet.
  • Require VPN Software or Hardware at both ends.
  • Uses Protocols like PPTP & L2TP.
  • VPN’s are created over technologies such as Dial-ups, DSL, leased lines, etc.

Example: Allows users to connect to a B) office networks from A) home network through the Internet
