[Sri] I though we had some discussion on this in the last IETF. In the context of Forwarding path, the key point is the interface between a control plane entity and a data plane entity. May be Marco has a better explanation > >- What is a controller "type"? [Sri] In deployments there could be controller entities on function basis; Ex: Mobility Controller, Routing controller ..etc. I agree with you we should not decompose the controller, but should look at this as one single entity. > >- Should QoS really be part of this work? I think notŠ [Sri] There is QoS support in all mobility architecture. QoS is tied to subscription and a key function of the mobility gateway. The CP entity should be able to provide the QoS parameters to the DP entity > >- Why would DP be querying CP? [Sri] Keeping the interface between CP and DP flexible allows us to support all types of scenarios. Lets take a simple example of a DP node loosing state, there should be mechanism to make a query to the CP entity. > >- Slide 13: It's not immediately clear why we need these identifiers, and >how they are used.
