The scope of this page is to explore the use of the ETSI (Nested) Network Services model at Design Time and Run Time in the context of the Network Slicing.
This analysis is based on a Presentation, User Operation Guidance for E2E Network Slicing Use case, from
LIN MENG, Swaminathan S, Chuanyu Chen shared during the latest LFNetworking virtual Event in Aprile 2020 (https://wiki.lfnetworking.org/display/LN/2020+April+Technical+Event+Schedule)
The best understanding of the model today is reported :
The Guilin Service IM allows for a (nested) Network Service (NS) model that is referenced from an ONAP Service.
Since the NS can be composed VNFs, CNFs, PNFs and nested NSs, the ETSI NS model is well suited to describe the hierarchical structure of 3GPP Network Slice Subnets.
NOTEs:
1) CST chain of objects and NST chain do not have any relation at DT.
