Pretty much every introduction to BSD sockets ever written uses a TCP echo
client server pair to start with. It then moves to a UDP echo client server
pair to illustrate datagrams.
We wrote the udp-echo.cc example when there was no TCP in the system. Now that
we have some TCPs, it would be useful to make a tcp-echo.cc and associated
applications. In our documentation, it would be very useful go through the
same kind of tutorial as everyone else in the world, with a tcp echo
walkthrough followed by a udp echo walkthrough.
Currently, what is quite easy to do in the real world (find out how to write
different flavors of sockets-based clients and servers) is much more hidden in
This sounds like a good topic for a sockets chapter in the tutorial.
