What problems are faced during the implementation of a network-transparent system?

A designer primarily faces two major problems while implementing a network-transparent system. They are as follows:

- The primary problem is to make all the processors and storage devices to appear transparent on the network. This 

implies that the distributed system should appear as a single centralized system to the users using the network.

There are two solutions to it:

- The Andrews files system

- The NFS system.

- Both these file systems (distributed) appear as a single file system to the user whereas in reality it may be distributed over the network.

- The secondary issue is regarding the user mobility. The designer would want any user to connect to the entire system overall rather than to a particular machine.
