PoC Drivers
1. Design time: End-to-end validation required when building new service chains
• Prior to publishing NSDs to the catalog
2. Run time
1. The chain must be activation tested as part of the fulfilment process.
2. Prior to customers are on-boarded
3. The chain must be constantly monitored that it provides its functionality according to SLAs
1. Prior to customers detecting issues
3. Frequent changes will occur to service chains during the life-time
1. No time to manually test and validate that changes will not break anything
2. Testing has to be programmable and automatable
4. Assurance capabilities must be designed into the lifecycle management of every service chain

Testing and Assuring the Network Service
• What is service assurance?
8
VNF VNF VNF Functionality, characteristics as seen by client
Traffic
Only aggregating NFVI KPIs from the VNFs to the Network Service does not tell how the service is working- No traffic before customers are
using it, too late- No service KPIs
Active tests at the service layer

NS Monitoring
22
• Needed “proxy” VNF in order to represent NS
• as first class citizen. NS can not have stand-alone monitoring parameters.

Key PoC Takeaways
25
5G network slice deployments require different, critical SLAs that must be met depending on slice use case
Active service testing and monitoring that is orchestrated, fully automated and provides DevOps flexibility is needed

Arctos Labs, Netrounds and RIFT.io have developed ETSI OSM PoC #1 with Telenor on Intel Architecture to
showcase solution.
