Rereading this draft, I realized that I am either confused by or disagree with the description of the "Network Slice Endpoint" contianed there. The endpoint that I think matters is the place where the IETF Network Slice Controller starts controlling the QoS and traffic delivery. The Controller doesn't care about the identity of the device outside of that. Figure 1 in section 4.2 seems to define that endpoint as the network slice realiation endpoint, and describes the network slice endpoint as the thing outside the IetF network slice. This seems counter-productive to me. It complicates teh relationship between the endpoitn and the service being abstracted. For example, if the service is beign delivered with MPLS, the Network Slice Endpoint likely can not put the labels on the packet for the MPLS, as it is outside of the IETF network Slice. So we will need yet another layer of classification, and yet more interworking. Further, someone has to get the queueing right for traffic coming out of the Network Slice Endpoint. But it is not part of the IETF Network Slice, so we don't have any way to get it right. If we define the edge of the space we care about co-incident with the edge of the space we influence, things get a lot cleaner. Yours, Joel
