Implementing a synchronous parallel TCP server

A synchronous parallel TCP server is a part of a distributed application that satisfies the following criteria:

• Acts as a server in the client-server communication model
• Communicates with client applications over TCP protocol
• Uses I/O and control operations that block the thread of execution until the corresponding operation completes, or an error occurs
• May handle more than one client simultaneously

A typical synchronous parallel TCP server works according to the following algorithm:

1. Allocate an acceptor socket and bind it to a particular TCP port.
2. Run a loop until the server is stopped:
   • Wait for the incoming connection request from a client
   • Accept the client's connection request
   • Spawn a thread of control ...
