TCP keep-alive is to detect a broken connection. It can be enabled with 
the LuaSocket library and setsocket( 'keepalive', true )
WebSocket keep alive (PING - PONG) does the same two layers higher. This 
may be implemented in the WebSocket library or application.

The latter is the more reliable operation as TCP keep-alive may be 
spoofed by, e.g. routers.
