Hi Satoru, 

Thanks for introducing the network slicing related work in DMM. 

While I don't have much expertise in DMM, my rough understanding is the separation of data plane and control plane in mobile network may have some requirement on network slicing, and for E2E network slicing it may be needed to jointly consider the slicing in mobile network and transport network. It would be great if you could help to describe the slicing requirements from DMM perspective. 

Best regards,
Jie
