Hi Hannu

Thank you for your interest in Network Slicing and for your valuable comments and suggestions which are already actioned as part of the update draft-01 - 'Network Slicing - Introductory Document and Revised Problem Statement'  planed for release this week.

Best Regards
Alex

It looks to me that the use cases are very close if not the same as what is being discussed in the 3GPP. Should the draft focus only those use cases that are of relevance to transport? And how much to use cases are then left? It seems that the slicing is more of a service provisioning and management notion that transport.

Equally, it shows similarly to the use case section that the scoping to transport slicing is not yet crisp enough; i.e. what is the scope of the problem? What makes this as transport issue? Isn’t this more of service problem than transport resource issue. This would need more motivation.
