Routing and IP

  • Subrata Goswami


Routing is the way IP packets gets transported in the Internet. Routers are computers that run one or more routing protocols. Routers usually have one or more interfaces. In the early days routers were used to connect a few LANs of various layer-2 protocols (e.g. Ethernet, Token Ring, ATM, etc.). Over time network evolved in complexity and currently it is loosely considered there are four different levels in a hierarchical network architecture: Local Network, Access Network, Metro Network, and Core (or Backbone) Network. A number of different IP routing protocols are overlaid in these networks to end-to-end connectivity.
