7C: Multilayered service orchestration and monitoring
18 June 2019

2. Key objectives of Task2 (1/2)
To build a consensus-building team drawn from the NRENs to consult with the wider NREN community (paying due attention to international collaborators) to establish and maintain consensus on a direction for interoperable network service orchestration, automation and virtualisation (OAV), which will then drive the further work of Task 2.
In response to specific identified use cases, to foster partner interoperability by piloting enhanced/new technology-agnostic service platform components, based on interoperable standards in a multi-domain environment.

3. Key objectives of Task2 (2/2)
To identify existing and/or develop new software components and APIs needed to enable single and/or multi-domain service orchestration and partner interoperability.
The task continues the work on the Service Provider Architecture (SPA) in particular looking for possibilities to grow the services offered through the self- service portal (SSP) and other SPA components.

4. The Service Provider Architecture (SPA)
The Service Provider Architecture (SPA) is a software architecture for an OSS/BSS solution bringing OAV (orchestration, automation and virtualisation) mechanisms to be used in the R&E environment by GÉANT and the NRENs.
Provide a common way to introduce new services
Reuse available common blocks
Fast forward new service development
User-centric
Unified view of service offerings, service monitoring and management
TMForum standards

10. SPA and Generic Connection Service (GCS)
Generic Connection Service (GCS) provides fully transparent Ethernet circuits over the GÉANT network using specific software tools for automated provisioning
GCS is being developed by WP7
SSP Portal to manage circuits in the GCS service
Close collaboration between WP6 T2 and WP7 T2
Test deployment in GÉANT VMs
R&S Inventory
Camel
Activiti
OTRS
SuiteCRM
Self-service Portal (SSP)

11. OpenNSA
Key resource facing component for the E-LINE service (and the GCS service)
Implementation of NSI
NSI network abstraction layer for Self-service Portal (SSP)
STPs as circuit end points

14. Ongoing activities and plans
Policy management in SPA
The use of SSP Portal to set up MS ExpressRoute connectivity
Integration of SSP with eduGAIN
Support for WP7 at production deployment of SPA with GCS in the GÉANT network
Input from the T2 Consensus Building group (a new service in SPA, new use cases)
Testing, testing, testing …

15. Conclusions
SPA – user-centric, standards-based OSS/BSS platform to manage network services
Continuation of OAV efforts started in GN4-2
Focus on standards and quality
Deployment in the GÉANT network – the GCS service
Collaboration with WP7 and WP9
We have plans to enhance and improve SPA
Next releases, next deployments, next services managed by SPA and use cases
