Use Case Overview & Description

The goal here is to enhance the CCVPN use-case to support Intent-based networking. Intent separates “what”(description of the desired outcome) from “how”(actual network configurations), and can be used to enable the full network automation. This requirement wants to make CCVPN offer an Intent NBI that can be used to enable the closed-loop automation of the transport network. Also, Cloud Leased Line (CLL) is another use-case which comes as an enhancement to CCVPN. In CLL, one VPN service connects an enterprise network to multiple clouds; i.e. multiple VPNs can co-exist (service-isolation, performance monitoring).

BUSINESS DRIVER

Executive Summary - An End-to-End 5G Network Slice consists of RAN, Transport and Core network slice sub-nets. This requirement is devoted to the realization Transport Slice sub-nets. It implements TN NSSMF, of which the functionality includes the modeling, orchestration and assurance of a Transport Slice. While TN NSSMF is a self-contained entity and thus this requirement can be independent, ensuring the integration with the E2E Network Slicing is an important aspect of this requirement. Standards-based interfaces and architectural framework (e.g., ETSI ZSM, IETF) are used by this requirement.

Business Impact - This requirement is important because Transport Slicing is an essential feature of the overall E2E Network Slicing, whose value is stated in its requirement.

Business Markets - Transport Slicing is an essential feature of Network Slicing. Any operators who would like to deploy ONAP-based Network Slicing solution will require this feature. Equally important, this feature (ONAP TN NSSMF) is self-contained and deployable. Thus, an operator who wishes to deploy an ONAP-based TN NSSMF may also benefit from it.

Funding/Financial Impacts - Intent CCVPN provides service automation, assurance, and the optimal use of network resources. Thus, it helps reduce OPEX for a service provider.

Organization Mgmt, Sales Strategies - There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider.
