ROUTER PROXY APP

How I would do it:

  1. ROUTER arrives
  2. it opens a tcp/ip connection to the PROXY
  3. it worms up, waits a few seconds, stretches :)
  4. it says: HELLO, I'm marek and I can accept 1k concurrent connections, and I have a cpu of a weight 2
  5. the PROXY responds with HELLO-OK
  6. The PROXY starts sending NEW_CONNECTION messages to the ROUTER
  7. messages flow in and out
  8. The ROUTER gets a SIGHUP from administrator, it should prepare to tear down

Passing TCP socket descriptors around

Passing TCP socket descriptors around

In linux, normally, it is impossible to "bind()" to the same TCP port twice. If you try to bind to the same port from second proces unix processes you'll see:

socket.error: [Errno 98] Address already in use
