Aether ROC Control API

Access

The ROC API specification can be accessed from the running ROC cluster at the API URL.

e.g. on a local system (if the GUI has been port-forwarded on port 8183) http://localhost:8183/aether-roc-api/

On the Production system it would be https://roc.aetherproject.org/aether-roc-api/

Note

Opening this in a browser will display a HTML view of the API (powered by ReDoc).

To access the raw YAML format use curl -H "Accept: application/yaml" http://localhost:8183/aether-roc-api/aether-2.0.0-openapi3.yaml This YAML format can be imported in to various different tools e.g. Postman

Background

The Aether ROC control API is available via REST or via gNMI. It is expected that most external consumers of the API will use REST.

The REST API supports the typical GET, POST, PATCH, DELETE operations:

  • GET. Retrieve an object.

  • POST. Create an object.

  • PUT, PATCH. Modify an existing object.

  • DELETE. Delete an object.

Endpoints are named based on the type of object. Some examples:

  • GET http://roc/aether/v2.0.0/connectivity-service-v2/enterprises. Get a list of enterprises.

  • GET http://roc/aether/v2.0.0/connectivity-service-v2/enterprises/starbucks. Get the Starbucks enterprise.

  • POST http://roc/aether/v2.0.0/connectivity-service-v2/enterprises. Create a new enterprise.

  • POST http://roc/aether/v2.0.0/connectivity-service-v2/enterprises/enterprise/starbucks/site/starbucks-newyork. Update the Starbucks New York site.

This document is a high-level description of the objects that can be interacted with. For a low-level description, see the specification (Access section above).

Identifying and Referencing Objects

Every object contains an id that is used to identify the object. The id is only unique within the scope of a particular type of object. For example, a site may be named foo and a device-group may also be named foo, and the two names do not conflict because they are different object types. The id is model specific. For example, a site has a site-id and an slice has a slice-id. The models are generally nested, for example slice is a member of site, which in turn is a member of enterprise.

In addition to the id, most identifiable objects also include a display-name. The display-name may be changed at any time by the user without affecting behavior. In contrast, the id is immutable, and the only way to change an id is to delete the object and make a new one.

Some objects contain references to other objects. References are constructed using the id field of the referenced object. It is an error to attempt to create a reference to an object that does not exist. Deleting an object while there are open references to it from other objects is also an error.

Common Model Fields

Several fields are common to all models in Aether:

  • <modelname>-id. The identifier for objects of this model.

  • description. A human-readable description, used to store additional context about the object.

  • display-name. A human-readable name that is shown in the GUI.

As these fields are common to all models, they will be omitted from the per-model descriptions below.

Key Aether Objects

The following is a list of Aether models, generally organized in a top-down manner.

Enterprise

Enterprise forms the root of a customer-specific Enterprise hierarchy. The Enterprise model is referenced by many other objects, and allows those objects to be scoped to a particular Enterprise for ownership and role-based access control purposes. Enterprise contains the following fields:

  • connectivity-service. A list of connectivity services that realize connectivity for this enterprise. A connectivity service is a reference to the SD-Core, and reflects either a 4G or a 5G core.

Site

Enterprises are further divided into Sites. A site is a point of presence for an Enterprise and may be either physical or logical (i.e. a single geographic location could in theory contain several logical sites). Site contains the following fields:

  • imsi-definition. A description of how IMSIs are constructed for this site. Contains the following sub-fields:

    • mcc. Mobile country code.

    • mnc. Mobile network code.

    • enterprise. A numeric enterprise id.

    • format. A mask that allows the above three fields to be embedded into an IMSI. For example CCCNNNEEESSSSSS will construct IMSIs using a 3-digit MCC, 3-digit MNC, 3-digit ENT, and a 6-digit subscriber.

  • small-cell A list of 5G gNodeB or Access Point or Radios. Each small cell has the following:

    • small-cell-id. Identifier for the small cell. Serves the same purpose as other id fields.

    • address. Hostname of the small cell.

    • tac. Type Allocation Code.

    • enable. If set to true, the small cell is enabled. Otherwise, it is disabled.

  • monitoring Configuration of how the monitoring framework of the site can be connected:

    • edge-cluster-prometheus-url the URL of the site’s Edge cluster Prometheus service

    • edge-monitoring-prometheus-url the URL of the site’s Edge monitoring Prometheus service

    • edge-device a list of monitoring devices that verify end-to-end connectivity

      • edge-device-id the identifier of the edge monitoring device. Serves the same purpose as other id fields.

      • display-name the user-friendly name for the edge device. It is recommended that the short hostname be used for the display-name as a convention.

      • description an optional description

Device-Group

Device-Group allows multiple devices to be logically grouped together. Device-Group contains the following fields:

  • devices. A list of Devices. Each device has an enable field which can be used to enable or disable the device.

  • ip-domain. Reference to an IP-Domain object that describes the IP and DNS settings for UEs within this group.

  • mbr. Per-device maximum bitrate in bits per second that the application will be limited to:

    • uplink the mbr from device to slice

    • downlink the mbr from slice to device

  • traffic-class. The traffic class to be used for devices in this group.

Slice

Slice connects a Device-Group to an Application. Slice has the following fields:

  • device-group. A list of Device-Group objects that can participate in this Slice. Each entry in the list contains both the reference to the Device-Group as well as an enable field which may be used to temporarily remove access to the group.

  • default-behavior. May be set to either ALLOW-ALL, DENY-ALL, or ALLOW-PUBLIC. This is the rule to use if no other rule in the filter matches. ALLOW-PUBLIC is a special alias that denies all private networks and then allows everything else.

  • filter. A list of Application objects that are either allowed or denied for this Slice. Each entry in the list contains both a reference to the Application as well as an allow field which can be set to true to allow the application or false to deny it. It also has a priority field which can be used to order the applications when considering the enforcing of their allow or deny conditions.

  • upf. Reference to the User Plane Function (UPF) that should be used to process packets for this Slice. It’s permitted for multiple Slice to share a single UPF.

  • SST, SD. Slice identifiers. These are assigned by Aether Operations.

  • mbr.uplink, mbr.downlink. Slice-total Uplink and downlink maximum bit rates in bps.

  • mbr.uplink-burst-size, mbr.downlink-burst-size. Maximum burst sizes in bytes for the maximum bit rates.

Application

Application specifies an application and the endpoints for the application. Applications are the termination point for traffic from the UPF. Contains the following fields:

  • address. The DNS name or IP address of the endpoint.

  • endpoint. A list of endpoints. Each has the following fields:

    • name. Name of the endpoint. Used as a key.

    • port-start. Starting port number.

    • port-end. Ending port number.

    • protocol. TCP|UDP, specifies the protocol for the endpoint.

    • mbr. The maximum bitrate in bits per second that UEs sending traffic to the application endpoint will be limited to:

      • uplink the mbr from device to application

      • downlink the mbr from application to device

    • traffic-class. Traffic class to be used when UEs send traffic to this Application endpoint.

Supporting Aether Objects

Connectivity-Service

Connectivity-Service specifies the URL of an SD-Core control plane.

  • core-5g-endpoint. Endpoint of a config4g or config5g core.

  • acc-prometheus-url. Prometheus endpoint where metrics may be queried regarding this connectivity service.

IP-Domain

IP-Domain specifies IP and DNS settings and has the following fields:

  • dnn. Data network name for 5G, or APN for 4G.

  • dns-primary, dns-secondary. IP addresses for DNS servers.

Template

Template contains connectivity settings that are pre-configured by Aether Operations. Templates are used to initialize Slice objects. Template has the following fields:

  • default-behavior. May be set to either ALLOW-ALL, DENY-ALL, or ALLOW-PUBLIC. This is the rule to use if no other rule in the Slice’s application filter matches. ALLOW-PUBLIC is a special alias that denies all private networks and then allows everything else.

  • sst, sd. Slice identifiers.

  • uplink, downlink. Guaranteed uplink and downlink bandwidth.

  • traffic-class. Link to a Traffic-Class object that describes the type of traffic.

  • arp. Allocation and Retention Priority.

  • qci. QoS class identifier.

  • pelr. Packet error loss rate.

  • pdb. Packet delay budget.

UPF

Specifies the UPF that should forward packets. A UPF can only be used by one Slice at a time. Has the following fields:

  • address. Hostname or IP address of UPF.
