Condition:

The App will talk with a Device with IP host. The device has its own communication protocol above IP layer (Transport layer) in Session layer.
To start talking, the App needs establish a Session by several times handshake on session layer.
The App needs keep feeding watch dog (timer) to let device know the session is still alive.
All of those processes should work without interrupt user interface.

Questions:

Which kind technology is better to involved? NSThread? NSOperaton? or GCD?
Is there any other solution can handle this job?

give `WebSocket` a try: http://en.wikipedia.org/wiki/WebSocket – Malloc Aug 01 '13 at 03:44
@Malloc Thank you! But my project needs to talk with a special hardware on the Session Layer. It has own protocol to encode and decode data. – Yi Jiang Aug 01 '13 at 03:52
If you're just running one background process, GCD is easy to implement and maintain. – JeffRegan Aug 01 '13 at 03:54
