DRAG DROP Drag and drop the functions from the left onto the correct Path Computation Element Protocol roles on the right 
I can see why C is marked as Initiator since it deals with starting the path request. But looking closer, function A seems more about handling updates rather than just responding, so it might be more limited to Responder. B definitely fits Both because it involves message exchange between both roles. I’d say sticking C with Initiator, A with Responder, and B with Both makes the most sense based on what each function is responsible for in the protocol.
I think C makes the most sense as Initiator because it talks about setting up the initial path request. A fits Responder since it handles replies and updates. B seems like it covers both roles because it deals with message forwarding and error handling, which can happen on either side. So yeah, C for Initiator, A for Responder, and B as Both looks right to me too.
B fits best as Both since it handles messages from Initiator and Responder.
I’d put C as Initiator, A as Responder, B only fits Responder here.
C for Initiator, A for Responder, B for Both.
