Overview

This side meeting, which has been organised by WP6 of the new GÉANT GN4-3 project, explores issues around the adoption and use of orchestration, automation and virtualisation (OAV) in the GÉANT and NREN communities.

Existing network infrastructures require significant operational workload when it comes to configuration, troubleshooting and management of network services. Traditional approaches require a significant amount of manual and repetitive configuration by network managers to deploy and manage a network service. Thus, in recent years, the R&E networking community has started taking steps towards low-level automation as a way to reduce human, error prone, intervention and instead abstract their multi-vendor, multi-technology platforms to a programmatic environment. Such low-level automation capabilities can further be exploited using service orchestration to synthesise high-level automation of workflows and processes, coupled with back-end configuration management databases.. Interoperability and standardisation are important properties for a successful transition towards automated, flexible and cost-effective service orchestration of single and multi-domain services.

The main purpose of the meeting is to act as a BoF session for the consensus building phase of the GÉANT GN4-3 WP6 activity on Network Services Evolution and Development by discussing the current status and future plans and trends concerning service orchestration in automated and/or virtualised network environments, with a view to exploring common ground within the R&E networking community that in turn can foster interoperability and use of common standards. The result of the consensus building will shape the future work of the project.

The project has already run a survey of NRENs, structured into the areas of current OSS/BSS systems, current OAV use cases, challenges in adopting OAV, future use cases, and how the GÉANT project might help the NRENs. The survey drew responses from 30 NRENs, the results of which were presented at the GN4-3 Future Service Strategy Workshop in Amsterdam on 9 May 2019, and where open discussion was then held on the future strategy and immediate next steps to take. The outcome of those discussions will be presented in this session to seed discussion.

In this session we include talks by some of the NRENs who are more advanced in their OAV work, so we can explore commonalities and differences in their approaches. General areas of discussion might include current use of automation by attendees (initial services targeted; what works, what does not, and lessons learnt), the appetite to build and deploy “service provider architectures” within (in particular) NREN networks;, including the standards used (such as TMF, MEF), their architecture elements;, interfaces, APIs, etc, and the appetite for trust and use of common interfaces (and AAAI) to support inter-domain service provisioning and configuration.
