Zafar, el al,

draft-ali-spring-network-slicing-building-blocks-03 has a very comprehensive description of various components of SR and how they can be put together.

However, I find the draft hasn't touched upon addressing the fundamental features of Network Slicing.
Maybe the term "network slice" means very different things to different people.

In 3GPP, a Network Slice includes the capabilities to manage, control and orchestrate the subset of network resources independently from other Network Slices.

The draft has a very good description on how SR achieves the On-demand policy, automatic steering and loop prevention. But the draft doesn't have any description on how subscribers can view and manage their dedicated network resources, or even what kind of network resources are visible/controllable by subscribers, which are the key components of Network Slicing. For example, can SR allows a subscriber to specify their traffic not to be shared on link/nodes with others?

Best regards,
Linda Dunbar
