Define RPC is nothing more than socket hiding

Question

Criticise the statement that ‘RPC is nothing more than socket hiding’.

Answer 1

I am not agree that ‘RPC is nothing more than socket hiding’ because Socket Programming only uses message passing between client and server. RPC, on other hand, utilizes higher level abstraction where the portmapper takes care of the socket communication via XDR (External Data Representation) language whilst the RPC abstraction layer takes care of the application. They are also responsible for converting the (remote) procedure’s (local data) parameters into a format suitable for network transportation and again into a format that can be used on remote host. The network-transparent transmission of data ensures both end machines can interpret the information content correctly.
