Note:

In order to make myself to familar with Java NIO and Network API, I write this tiny tcp servers Java framework.

It can handle thousands client tcp connections at same time.

Base on the framework, I implement a simple echo server as an example.

And I also write a echo testing tool---echoStressTest.erl by Erlang.

I use echoStressTest.erl to simulate thousonds clients to connect the tinyTCPServer.

Build:

  1. Make sure you have installed the JDK 1.7 and ant

  2. run ant

Usage:

  1. execute "ant run", or "java -cp tinyTCPServer.jar tinyTCPServer.example.EchoServer"

    The echo server will listen to the 6678 port to accept the tcp connection.

    Please refer to tinyTCPServer.example.EchoServer.java

  2. run your client to access the echo server.

Stress Testing:

1) Make sure you have installed the erlang(http://www.erlang.org/)

2) execute command: "./echoStressTest.erl -h" to see the usage info

3) If you need to run a lot of concurrent connections testing, 

   Please tune your linux server at first, and check the system limit(ulimit -a)
