Nope I was decomposing a Measurement agent... somewhat like this


     			  	 --------------------
				|  Measurement Agent |
      			|   Control function |
				 --------------------   
					/	   \		
			           /          \
  	      --------------------        -----------------
           |  Test initiator    |      |  test responder |  
	     |    function        |      |    function     |  
		--------------------        ----------------- 

Where a Measurement agent has two separate sub-functions under it, both biding for resources of running a test.
The measurement agent control function talks to the Measurement controller.
The test initiator / responder functions roll up under the Measurement agent, but can work independently of each other.

I think we are facing terminology clashes. Can we agree to use one terminology? I assume what you call a 'test initiator' is what [1] calles a Measurement Agent and what you call a 'test responder' is what [1] calls a Measurement Peer. These are functions. How you package them is an implementation decision.

I am trying to translate from what I assume is your terminology but I get somewhere lost in the second sentence.
