IP Routing

• Each router or host makes its own routing decisions

• Sending machine does not have to determine the entire path to the destination

• Sending machine just determines the next-hop along the path (based on destination IP address)

  • This process is repeated until the destination is reached, or there’s an error

• Forwarding table is consulted (at each hop) to determine the next-hop
