CAMARA - Quality on Demand Beta
The Quality-On-Demand (QoD) API provides programmable interface for developers to request improved latency or throughput performance.
0.9

Getting started



Introduction

The CAMARA Quality on Demand API provides a standardized mechanism for requesting, retrieving and terminating a mobile connectivity session with improved performance (bandwidth and latency).

When an application on a mobile device triggers an enhanced QoD it has to provide expected quality of service (qos) profile between the user equipment (ue) and the application server (as). It may also provide a requested duration, ports, and a notification url.

The QoD server will (if provided) sent a notification to this notification url when the session terminated. In future release we can add other notification type.

Subscribe to the API

You get the Authorization header credentials when you register your application on the Orange Developer Console.

API Authentication

HTTPS requests to the REST API are protected with 2-Legged OAuth. To learn more about how Orange Developer handles authentication, please refer to our documentation.

In short, you will use your Orange Developer Authorization header as authorization_header for the Basic authentication with Orange Developer.

curl -X POST \
-H "Authorization: {{ authorization_header }}" \
-d "grant_type=client_credentials" \
https://api.orange.com/oauth/v3/token

In response, you will get an access_token.

{
       "token_type": "Bearer",
       "access_token": "66AeYJF8eJQ...2SjkFg9LB1LePC",
       "expires_in": "3600"
}

API Description

Summary of resources

This API has two resources managed by QoD server: sessions and qos-profiles .

  • qos-profiles are the profiles managed by Orange server. A profile is list of technical attributes defining quality on demand performance. This could be considered as 'catalog' information.
  • sessions is a quality on demand session requested to Orange server between a device (defined by IP address & port) to an application on a server (defined by IP address & port). A session request MUST provides both device/application information but also the qos-profiles wished.

API consumer mays provide in POST /sessions a callback URL on which notifications (eg. session termination) regarding the session can be received from the service provider. The notification will be sent to this URL and accordingly to the OAS callback definition

Retrieve QoS Profile information

The operation GET "https://api.orange.com/camara/quality-on-demand/orange-lab/v0/qos-profiles allows to get all Qos Profile managed by Orange server.

An array of QoS profile is provided in the response. for each QoS profile following information are provided:

maxUpstreamRateThe maximum best effort data for upstreamRate
maxUpstreamBurstRateThe burst rate for best effort data - Not managed in Orange Lab implementationRate
targetMinDownstreamRateThe target minimum data rate. Set to zero when no target minimum is defined in this profile. Not managed in Orange Lab implementationRate

maxDurationThe maximum length of time that this profile can be deployedDuration (see below)
priorityThe priority that will be given to sessions using this QoS profile, where a lower value indicates a higher priority - set to 0.0 in Orange Lab implementationnumber

unitenum: Kbps, Mbps, Gbps, Tbpsstring

Duration type is defined as following:

NameDescriptionType

unitenum: Nanoseconds, Microseconds, Milliseconds, Seconds, Minutes, Hours, Daysstring

It is also possible to query all information for one QoS profile id by using operation GET "https://api.orange.com/camara/quality-on-demand/orange-lab/v0/qos-profiles/{name}

In order to be globally unique it has to be formatted in international format, according to E.164 standard, optionally prefixed with '+'. Optionally prefixed with '+'stringNo
Ipv4AddressThe device should be identified by either the public (observed) IP address and port as seen by the application server, or the private (local) and any public (observed) IP addresses in use by the device (this information can be obtained by various means, for example from some DNS servers).See below information on device Ipv4 addressNo

Most frequent errors

If a session is already existing for the same device an error 409 will be sent

HTTP/1.1 409 Conflict
Content-Type: application/json
{
{
  "code": "CONFLICT",
  "status": 409,
  "message": "Another session is created for the same device"
}
}

There are some cases where your client application will no longer gain access to API resources, and get an error back.

Please check the following points:

  • Here, you attempt to use an expired or revoked access_token and you get an invalid token error. You will have to request a new access_token. As an example:
HTTP/1.1 401 Unauthorized
Content-Type: application/json
{
  "code": "UNAUTHENTICATED",
  "status": 401,
  "message": "Authorization failed: ..."
}
  • Here, you removed your subscription to the API so that the capability to generate an access_token is not allowed anymore. As an example:
HTTP/1.1 403 Forbidden
Content-Type: application/json
{
  "code": "PERMISSION_DENIED",
  "status": 403,
  "message": "Operation not allowed: ..."
}
