From an IP router perspective, packets enter a router interface, and they contain an IP address that identifies the destination device. The router uses the IP address to perform a routing table lookup to see which router interface is the shortest path to the destination. A CO switch is similar in that it too contains a table. But instead of IP addresses, the table consists of telephone digits. These digits have a hierarchical structure similar to IP addresses. A hierarchical structure helps to reduce the lookup table size and makes decision making faster and more efficient.
