IoT-NGIN has been listed in the ETSI OSM Ecosystem Research by our partner, i2CAT (https://osm.etsi.org/wikipub/index.php/Research#IoT-NGIN ).

ETSI-hosted Open Source MANO (OSM) delivers a production-quality MANO stack for NFV, able to consume openly published information models, suitable for all VNFs and independent of virtualized infrastructure managers (VIMs). OSM is aligned to NFV ISG information models while providing first-hand feedback based on its implementation experience. The following figure illustrates OSM interaction with VIMs and VNFs in which OSM interacts with the VIM for the deployment of VNFs and VLs connecting VNFs, and ii) OSM interacts to the deployed VNFs in a VIM to run day-0, day-1 and day-2 configuration.

In order for OSM to work, it is assumed that:

  • Each VIM has an API endpoint reachable from OSM.
  • Each VIM has a so called management network providing IP address to the VNFs.
  • That management network is reachable from OSM.

Moreover, OSM is capable of 

  • Network service lifecycle management in different types of infrastructures, across different locations and through different VIMs such as OpenStack and Kubernetes, 
  • on-boarding and management of network service descriptors,
  • performance and fault management of the network service, and
  • provision of a platform to create networks as a service and to manage them conveniently later. 

In IoT-NGIN project, i2CAT utilizes ETSI OSM as the NFV MANO for the orchestration of container-based network services, which is integrated in its Network Slice Management tool (SOE) offering network slice management API features as a part of the 5G Resource Management API. The Slice Manager as a part of SOE provides various features in three different scopes:

  • Management of infrastructure resources from different domains such as registration of cloud/edge and RAN resources.
  • Slice management through which reserved resources per slice are registered and configured. These reserved resources are composed of i) cloud/edge compute chunks, ii) RAN chunks, and iii) 5GCN/Cloud/edge network chunks.
  • Network services management, which not only includes service instantiation, termination, and migration, but also service update, and recovery. 

The developed network slice management API within IoT-NGIN will enable the service migration for IoT devices so that they can run their processes as container-based network services in the 5G edge cloud.
