ABSTRACT:

One of the many challenges facing the adoption of 5G is the validation and verification of 5G services in different platforms and testbeds. Validation is sometimes expressed by the query "Are you building the right thing?". Verification is similarly expressed as "Are you building it right?". 5G services typically leverage multiple complex Virtual Network Functions (VNF's) and Network Services (NS's). These services need not only to work across different execution platforms but also must work in a verificable and repeatable manner. Service Operators must be confident that VNFs and NSs will behave as expected when services are launched in production. As such, validation of these services proves that the service conforms to what was desired by the customer, i.e. "the right thing". The verification of these services proves that the service works and is fit for production, i.e. "built right".


This document, Deliverable D3.3, describes the features and architecture of the final release for the Validation and Verification (V&V) platform, as well as the overall DevOps testing lifecycle for service creation. A DevOps lifecycle is all about agility and automation. Each phase in the DevOps process ow focuses on closing the loop between development and operations and driving production through continuous integration, delivery, deployment, and feedback. As such, this document explains the three-phased approach to the service creation and testing lifecycle and then describes the technical components that were created to deliver such a lifecycle. D3.3 describes the use cases, scenarios and tests of the V&V platform for each of our three industry pilots (Communications, Immersive Media and Smart Manufacturing). The V&V platform features were driven by the requirements of the three pilots that illustrate the extensibility and interoperability of the V&V platform, while also providing concrete examples of services and their tests. More details on that will be provided in D7.3 (M33).


The 5GTANGO V&V platform confronts the multidimensional challenges posed by 5G services and networks to help achieve the cloud-native agility requested by our end-users to be competitive in their respective marketplaces. The platform is developed by catering to the respective needs of different operators and different services. Using an agile development process, combined with Continuous Integration and Continuous Delivery (CI/CD) best practices, the V&V platform provides a vehicle for this service-agnostic evolution of the platform, whilst also allowing platform extensibility where specific features for tests can be added incrementally over time. The V&V platform addresses the very real problem of test verification for service operators, and in doing so it can also increase the confidence operators have in deploying third-party provided network services. A better, more automated, test qualification platform will help promote the adoption of 5GTANGO V&V Platform across multiple vertical segments, creating a long-lasting ecosystem where the software evolves and matures far beyond the project development timeframe.
