The network installation services determine the data paths, which may be used between any pair of nodes in the network. There are several organizations such as banks, insurance companies, hospitals, railways etc. that need on-line processing of large number of transactions and require many computer system to communicate and interact with each other on the same network. In such a computing environment the role of network installation services is vital.
