Spring 2018						Exercise 4
-------------------------------------------------------------------
A client-server application is running on top of a TCP connection
with two sides: side1 and side2. The application client runs on top
of side1 and the application server runs on top of side2.

Which one of these two sides has a circular buffer to store the data 
bytes received from the other side until these bytes are read by the
application? Explain your answer.

--------------------------------------------------------------------
Solution
--------------------------------------------------------------------
In general, the TCP connection is two-way sending data bytes from
side1 to side2 and from side2 to side1. Therefore, each of the two 
sides has a circular buffer to store the data bytes received from
the other side until these bytes are read by the application.
