How address resolution is performed with table lookup? Explain with the help of a suitable example.
The approach of table lookup to address resolution needs a data structure which contains information regarding address bindings. The table contains an array.
All entry in the array consists of a pair [P,H], here P is a protocol address and H is the corresponding hardware address. A separate address binding table is utilized for each physical network. Therefore all IP addresses into a specified table have similar prefix. For illustration the following address binding table equivalent to a network with the class C number 197.15.3.0. Consequently, each IP address into the table will start with 197.15.3 prefix. The chief advantage of such table lookup approach is as a table can store the address bindings for an arbitrary set of computers upon a specified network.
