Thanks, every one I got it from another source and I realize that might question was not defining well. So, the answer i found is that SIP existed at all layers of OSI model. http://my.safaribooksonline.com/getfile?item=NzE1ZC9wL210L2M5Z2lzZTg5MDg3MWFzNHM0NXJhNzVfZWdwLy9ndHIwaWFzYzQxOV8uMTBqcHNo

They are both application-layer protocols.

As a matter of fact they don't exist in the OSI model at all. They are both TCP/IP protocols, and therefore fit into the application layer of the TCP/IP model.
