Hi, Authors:
Interesting work, two quick comments are:
1.Section 4.1 of draft-lee-teas-actn-5g-transport-00 said:
"
The MTNC represents a transport network slice, QoS configuration for a transport path/VN between two 3GPP user plane functions (e.g., between gNB and UPF and between UPF-ULCL and UPF-PSA) and between UPF-PSA and Application Servers (AS). The MTNC include a set of requirements, such as quality of service (QoS) requirements, class of service (CoS), a resilience requirement, and/or an isolation requirement, and so on, according to which transport resources of a transport network are provisioned for routing traffic between two service end points.
"
How does MTNC relate to 5QI and DSCP? How is the problem solved without MTNC proposal today?
2. The relationship between 3GPP slice and Transport slice is N:M, How N 3GPP slice is mapped to M Transport with MTNC identifier?
