Main features of the 5GCity Orchestrator – Final Release
This section lists and explains the main features offered by the released 5GCity Orchestrator software in its final release. The goal here is to list features that have been implemented based on the specifications provided in Deliverable D4.1. Many of these features were present in the interim release (Deliverable D4.2) and have been further tested or enhanced for the final release. Components and features that are completely new in this final release are annotated as. The rest of listed features have undergone a refinement and bug fixing process thus incorporating updates aimed at stabilizing operation.

5GCity platform component for Authentication and Authorization of Platform users.
- Integration of state-of-the-art authentication and authorization in front of all interfaces exposed by the platform components, based on Keycloak and Gravitee.
- Support rules for data access security required by multi-tenancy features of the neutral hosting model.
Slice Manager
Manage infrastructure owner resources.
- Create, read, and delete “partitionable” resources that shall be offered by the infrastructure owner/neutral host for the creation of slices, namely:
- Compute resources.
- Physical network resources (for the network interfaces of the above compute resources)
- Access network resources (currently only Wi-Fi APs)
- Network link resources (for the links that interconnect compute and access network resources)
Manage chunking/partitioning of infrastructure owner resources
- Create, read, and delete chunks (i.e., partitions) of the previously listed resources, by specifying quotas, i.e., what part/percentage of the whole resource a chunk shall include/reserve a chunk. According to the supported resources (see previous feature), the following chunks are currently supported:
- Compute chunks (provisioned based on OpenStack projects)
- Physical network chunks (provisioned based on OpenStack physical networks)
- Access node chunks (currently only for Wi-Fi access)
- Physical link chunks (as portion of the bandwidth offered by a physical link, currently not enforced by an SDN controller)
Manage slices
- Create, read, and delete slices, which are defined as collections of previously listed chunks, belonging to a specific slice user and potentially having specific characteristics.
- Activate of the RAN ingredients of a slice on-demand after its creation. This involves:
- The automated launching of vEPC (virtual Evolved Packet Core) instances if the slice includes an LTE/5G RAN part.
- The automated launching of a DHCP service if the slice includes a Wi-Fi part.
- The appropriate matching of VLAN tags used in the core network with those used in the RAN.
Manage slice users
- Create, read, update, delete (CRUD) slice users, who can manage slices and deploy network services on them.
Manage network services (on slices)
- Create, read, and delete network services, including deploying and un-deploying network service instances on specific slices.
Integrate intelligent resource placement for service instances
- For the aforementioned network services an optimal deployment is retrieved by providing slice and service info from the placement module, and then appropriately triggering the placement-aware API of the MTO, including all the required placement details.
Infrastructure Abstraction
Provide abstraction of multiple underline RAN controllers and technologies to the Slice Manager.
- Create, read, update, delete (CRUD) RAN controller profiles.
Manage a catalogue of virtualized network resources.
- Create, read, update, delete (CRUD) a dictionary of virtualized resources.
Delegate virtualized network resources requests from the Slice Manager to the controllers.
- Receive and retransmit requests of virtualized network resource to/from different RAN controllers.
MTO
Provide abstraction in front of multiple underlying orchestrators:
- Delegate service lifecycle management calls to ETSI Open Source Mano (OSM).
- Retrieve MEC application descriptors associated with instantiated network services from a catalogue and pass them to a MEC platform to be applied.
Implement fine-granular placement instructions for the service instances:
- Translation of placement instructions into configuration commands as required by the NFVO in order to realize the desired placement.
MEAO
Manage Mobile Edge (ME) platforms
- Create, read, update, delete (CRUD) operations, allows the definition and lifecycle management of ME platforms running on different mobile edge hosts
Manage ME applications

- Register a service to any ME platform registered with this MEAO.
- Removal of a given service from any ME platform registered with this MEAO.
- Update of a given service from any ME platform registered with this MEAO.
- Service discovery within any ME platform registered with this MEAO.
Manage the Domain Name Service (DNS) rules across ME platforms
- Create, read, update, delete operations, providing a dynamic DNS service for a given ME platform.
MEC-Platform
Manage MEC services
- Create, read, update, delete operations exposed by the ME platform enabling:
- Register a service in this platform
- Removal of a given service from this platform
- Update of a given service in this platform
- Service discovery within this platform
Manage DNS (Domain Name Service) rules
- Create, read, update, delete operations, providing a dynamic DNS service for all ME apps connected to this ME Platform.
Manage ME app notifications
- The ME Platform can notify other ME Apps or Services about lifecycle management changes of a given ME app.
OSM
As NFVO core engine, we use OSM Release 6 by referring the official documentation in https://osm.etsi.org/ to describe its features.
- Note 1: The 5GCity extensions to ETSI OSM release 5 (which can be found in the modified OSM version of the 5GCity GitHub repository) enabled the support of fog05 (https://projects.eclipse.org/proposals/eclipse-fog05) as a VIM, in order to add MEC features required by the 5GCity platform. These additions (5GCity contributions) have been integrated in OSM release 6, so now we are just using release 6 unmodified.
- Note 2: 5GCity partners have contributed in the OSM WIM plugin, which was already included also in the official OSM Release 5 and can be used to implement part of the Infrastructure abstraction and WAN resource manager of 5GCity.
Monitoring
Manage monitored nodes
- Create, read, update, and delete operations allow the definition of a resource that is exposing monitoring parameters.
Manage monitored jobs (exporters)
- Create, read, update, and delete operations allow the definition of a job as the group of monitoring parameters to be collected, e.g.:
- NODE (VM related metrics).
Manage monitored services
- Create, Read, Update, Delete operations that allow the definition of the set of resources and jobs that are used to monitor a service.
Expose collected metrics
- Query monitoring parameters, e.g.:
- Read all system (VM) metrics for a resource
- Read all system (VM) metrics for all the resources of service
Support for custom metrics
- Register and query custom (service-specific) metrics.
View collected metrics
- Expose monitoring parameters through a local Dashboard, grouped by service and/or resource.
Alerting support (partly implementing the 5GCity SLA Manager functionality)
- Create Alert Rules to define thresholds and alerts
- Send Alerts to a custom endpoint (e.g.: Dashboard)
- Get the list of active alerts
Resource placement
Calculate the optimal placement of VNFs that compose a network service by taking into consideration the network topology and resources.
