traffic_relay

This repo used as an example to demonstrate how to use epoll in a single thread, served both as client and server.

TODO

• Eliminate the use of hard-coded address and port.
• Add example of kqueue, and maybe iocp.
• Exploring io_uring.
• Refactor, especially add more comments.

Usage

1. Compile main.cpp using

   g++  main.cpp -lpthread -o main
   

2. Running main

   ./main
   

3. In another machine, use a tcp server listen to the port 50007

   nc -l 50007
   

4. In another machine, use a tcp client connect to the port 50007

   nc <ip> 50007
   

5. Try to send some data to the server or send data back from server to the client, and see the result. You could also use multiple clients to connect to the server.
