Question

I just need some help understanding this problem. Pointing in the right direction would be very helpful.

C++ in a UNIX Environment

Part1 Create a one-directional ring of pipe for N processes (N ≥ 1)

Part2 Create a one-directional ring of pipe for N threads

Part3 Create a one-directional ring of socket for N hosts (or all in one).

                        You may run N processes in one host.

                        Each process has two designated ports - one for sending and the other for receiving.

                        Each program for each process will be run with an argument telling which process (Nth process)

                        You may assume that each process has a table of process with 2 ports as following:

Process i	IP address	Port# to send	Port# to receive
0	127.0.0.1	9000	9001
1	127.0.0.1	9100	9101
2	127.0.0.1	9200	9201
and so on

When N processes (or threads) in a ring are up and ready, Process 0 sends a message to be received by Process 1, and so on, to back to Process 0 and done. Whenever a process sends or receives a message, it prints its process # (N), "the message", and "sent" or "received".
