The Network.hpp File

// Network.hpp: The header file for the network implementation 

// class. While not a first-class citizen in this design (i.e., a key

// abstraction), it is a very important implementation class. This

// class is a basic wrapper for the physical network, whatever it

// happens to be (a pipe, sockets, a LAN, a WAN, a telephone, two

// soup cans). The data of the Network class can be filled in with the

// reader's favorite mechanism. The methods of the class clearly

// state where a send buffer or receive buffer needs to be placed.

// This code has a simulation so that both sides of the application

// can be tested.
