Internet-Draft This memo specifies RESTful application layer interface for gateways providing operations against non-IP devices. The described interface is extensible. This memo initially describes Bluetooth Low Energy and Zigbee as they are the most commonly deployed.

Introduction

Scope Low-power sensors, actuators and other connected devices introduced in environments and use cases such as building management, healthcare, workplaces, manufacturing, logistics and hospitality are often battery-powered. Often they do not support wireless of wired interfaces that support the IP protocol. Most of these environments however mainly support IP-based networking infrastructure. Therefore, applications on the IP network that aim to communicate or receive telemetry from these non-IP low-power devices must do so through a gateway function on the IP network. This gateway functions then translates the communication to the non-IP protocol that the low-power device supports. Promiment examples of such protocols are and .

There have been efforts to define Gateway functions for devices that support a particular protocol, such as a BLE GATT REST API for BLE Gateways (), however they have been limited to a single protocol or a particular use case. In absence of an open standard describing how applications on an IP network communicate with non-IP devices, bespoke and vendors specifia implementations have proliferated. This results in parallel infrastructure of both gateways and non-IP networks being deployed on a case by case basis, each connecting separately into the IP network, with a distinct set of APIs. At the same time, wireless access points supporting IP-based wireless connectivity are deployed ubiquitiously. Many of these wireless access points are equipped with multiple wireless radios, of different types. These radios can transmit and receive different frame types, such as and . This specification aims to define a Gateway API for these Non-IP protocols that can be leveraged by this wireless infrastructure in order to connect Non-IP devices into IP networks. A standardized Non-IP Gateway interface has following benefits: Avoid the need for parallel Non-IP infrastructure. Avoid the need for applications to perform bespoke integrations for different environments. Faster and more cost-effective adoption of Non-IP devices in IP network environments.

Non-IP Gateway functions A non-IP gateway MUST provide at least following functions: Authentication and authorization of application clients that will leverage the gateway API to communicate with Non-IP devices. The ability to onboard Non-IP devices on the Non-IP Gateway. Onboarding ensures that the Non-IP Gateway can identify a device and has sufficient context about the device to service gateway API requests. It also ensures segmentation of devices that were onboarded by particular applications. A persistent inventory of onboarded devices mapping to the application that onboarded them and the access point/radio that is serving them. An API that allows for bi-directional communication to non-IP devices. One or more channels to process requests, responses, and asymmetric communications with the non-IP radio resources (Access Points) in its inventory. The ability to stream telemetry received from non-IP devices in real-time to applications on the IP network. The onboarding function is out of scope of this document, but can be provided by a provisioning interface such as leveraging . All other defined functions are supported by Non IP-Control (NIPC). The Application gateway is a network functions, so its goal is to proxy payloads between Non-IP and IP networks. It is not intended to be a middleware functioni that interprets, decodes or modifies these payloads.

shows us applications, the application layer gateway (ALG), an access point (AP), and a device (D). The applications, application layer gateway and access point are deployed on an IP-Network. The AP also has a Non-IP interface, which it uses to communicate with the device. The Application is deployed in a different administrative domain than the network elements (ALG & AP). The role of the ALG is to provide a gateway function to applications wishing to communicate with non-IP devices in the network domain served by the ALG. Applications implementing Non-IP Control can leverage RESTful interfaces to communicate with Non-IP devices in the network domain and subscribe to events levering MQTT.

Interaction flow In order to enable a network wishing to offer NIPC ALG functions, the network administrator authorizes application(s) to perform operations on the Gateway. This happens out of band and may be accomplished by means of exchanging tokens or public keys. Authorization can be role-based. The 3 primary roles are: Onboarding: Authorize an onboarding application against a SCIM server co-located with the gateway. Control: Authorize applications that may control devices. Data: Authorize applications that may receive telemetry.
It is possible to further refine roles down to an API basis. Applications can perform the API requests they were authorized for. In order for application to perform a NIPC operation on a device, the device must be first onboarded, for example by means of SCIM. Previous steps are prerequisites and not within the scope of this specification, but are provided for context.i Subsequent operations are defined by NIPC. An application authorized for Control can perform NIPC calls to the gateway in order to establish bi-directional communication to one or more devices. Optionally, also set up a publish/subcribe topic to receive streaming data from a device (telemetry interface). An application authorized can receive streaming data on a pub/sub topic configured by the control interface (telemetry interface).

Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 when, and only when, they appear in all capitals, as shown here.

Architecture

Overview Non-IP protocols, such as BLE or Zigbee, typically define a number of basic operations that are similar across protocols. Examples of this are read and write data. NIPC leverages a unified API to support those operations. NIPC defines actions, which are implemented as REST over HTTP request-response APIs. NIPC Also defines events, which are implemented as MQTT topics. In case NIPC is not leveraged in combination with a data model such as ASDF , which can define the properties of a devices, NIPC also support registrationsr. REgistrations perform mapping of properties to protocol-specific attributes. All operations pertain to a devices or a group of devices, which are addressed by UUIDs. These UUID's were generated at time of onboarding and returned to the application, for example in a SCIM response.

NIPC Operations NIPC adheres to nomenclature defined by Semantic Definition Format (SDF) for Data and Interactions of Things . Therefore NIPC defines actions and events on properties.

Actions NIPC supports 3 types of actions: connection: Allows an application to establish to manage connections with a device (if so required by the technology). property: Allows applications to read or write device properties. In case the property supports streaming data, a subscription property can be managed. broadcast: This allows the application to send a broadcast message to a device or group of devices.

Registrations In absence of a model such as SDF that defines device properties, NIPC allows an application to register them. NIPC defines 2 types of registrations: property: Manage registrations of properties and their protocol mappings. For example, a property called temperature can be mapped to a BLE Service Characteristic. event: Manage registrations of events and their MQTT properties such as MQTT topic definition.

Extensions The final set of operations are not fundamental NIPC operations, but are extensions. Extensions are compound API's. They leverage basic NIPC operations but combine multiple operations in to one API call for efficiency. An example of this is the the bulk operation, allowing to send multiple operations is one operation. extension allows for extensions, either generic extensions that anre IANA registered, or vendor specific extensions

Events Events are published over MQTT. Events can be normal sreaming data, but also broadcasts or connection events.

Protocols NIPC actions, registrations and extensions are request/response APIs. They makes use of a JSON schema over RESTful HTTP. NIPC events are encoded in CBOR () and delivered over MQTT.

Schema

Device schema Most operations (except registations) are executed against a device or a group. NIPC operations refer to either of these as "Object" with an ID as an identifier. The common schema for Object is defined as follows: Attribute Req Type Example id T uuid 12345678-1234-5678-1234-56789abcdef4 type T enum device, group technology F enum ble, zigbee where- id is the unique uuid of the device. This is generated when registering the device, for example against a SCIM server. As such this ID is known both to the application as well as the NIPC Server. type is either "group" or "device". technology is the radio technology supported by the device. The mappings defined in this spec are "ble" or "zigbee". Mappings are extendable to new technologies. Example device object:

Property mapping An object can support one or more communications protocols. Even though Non-IP communications protocols all perform operations on properties, implementations differ between protocols. For example BLE will address a property as a service characteristic, while a property in Zigbee is addressed as a property in a cluster of an endpoint. In order for NIPC to support protocol-agnostic APIs, a property mapping is required between a NIPC property and a protocol-specific property. A property mapping can be done by means of a property registration API. Property mapping allows for integration of new protocols in NIPC, new mappings can be created without the need to update the base schema.

BLE | - BLE property | |> Zigbee - Zigbee property ]]>

As shown in , protocol-specific properties must be described in a protocol object, for example a "ble" or a "zigbee" object. Attribute Req Type Example ble T object an object with BLE-specific attributes zigbee T object an object with Zigbee-specific attributes where- "ble" is an object containing properties that are specific to the BLE protocol. "zigbee" is an object containing properties that are specific to the Zigbee protocol. Other protocol mapping objects can be added by creating a new protocol object Example property mapping:

Protocol mapping allows applications to perform a one-time registration to a propertyID for a property, and leverage the propertyID in all API calls that perform an operation on this property. It might be useful for applications to directly use protocol objects in action API's as well, therefore there are a limited set of API's avaialbe that have protocol objects directly embedded in the API, in ordur to perform operations on properties without having to first register them.

Response As most operations have a common base schema, based on a device ID and a property, so do responses. Every NIPC API returns a status in the response, as well as a requestID, which allows for tracking and logging of requests and responses. If the operation was performed on a device or group, the ID is also returned. If the operation is to read or write a property, the resulting value is also returned. Success response: Attribute Req Type Example status T enum SUCCESS id F uuid 12345678-1234-5678-1234-56789abcdef4 requestID F uuid abcd0987-1234-5678-1234-56789abcdef4 Example success response:

Failure responses additionally include an error code and optionally a reason, which contains a textual explanation of the error. Failure response: Attribute Req Type Example status T enum SUCCESS id F uuid 12345678-1234-5678-1234-56789abcdef4 requestID F uuid abcd0987-1234-5678-1234-56789abcdef4 errorCode T int 12 reason T string "Not Found" where- status is the status of the request, either "SUCCESS" or "FAILURE". In case of failure an error code and reason are added. id is the id the operation was executed against, found in the request requestID is a correlation ID that can be used for end-to-end tracing. errorCode is a numerical value representing the error. reason is a human readable explanation of why the error occurred. Example failure response:

NIPC Actions The primary goal of NIPC actions is to exchange data with a Non-IP device, by means of reading, writing or streaming NIPC properties to applications. An explicit connection may be required, which is also an action. An application may also want to transmit a broadcast.

Connections A connection is an operation that establishes or tears down an association or connection with a device. Optionally during connection setup properties supported by a device can be discovered. /action/connection The connection API allows an application to request to connect to a device. Operations: Connect to a device: POST Return active connections: GET Disconnect a device: DELETE

Connection API

Connect to a device Method: POST /action/connection Description: Connect to a device Parameters: None Request Body: an Object, as defined in optionally a set of properties to be discovered. These are supplied in protocol objects, as defined in . In the case of BLE, if no protocol object is included, service discovery is performed to discover all supported properties when connecting to a device. Optionally, service discovery may be limited to properties defined in the "ble" protocol extension. The services to be discovered can be added in an array. Property discover can be buffered across connections, so the API also supports caching parameters. Connection retry parameters Example body of a connection without specific discovery of properties:

where- "id", "type" and "technology" are part of the object definition (device or group), as defined in . "retries" defines the number of retries in case the operations does not succeed "retryMultipleAPs" can be used in case there is an infrastructure with multiple access points or radios that can reach the device. If set to "true" a different access point may be used for retries. In case the application would like to discover specific properties of a device, a protocol object can be added that defines what properties should be discovered. Example body of a BLE connection with specific discovery of properties:

where in the BLE protocol object: "services" is an array of services defined by their serviceIDs. "cached" refers to whether the services need to be cached for subsequent connects, in order not to perform service discovery on each request. "cacheIdlepurge" defines how long the cache should be maintained before purging some devices support notifications on changes in services, "autoUpdate" allows the network to update services based on notification (on by default) "bonding" allows you to override the bonding method configured when onboarding the device Response: Success responses include standard success response properties as defined in as well as a protocol object with an array of discovered properties, as defined in the specific protocol. For example, for BLE, this is an array of supported services, which in turn contains an array of charateristics, which in turn contains an array of descriptors, as shown in .

NIPC Registrations NIPC allows an application to register properties to use in action API's. NIPC supports 2 types of registrations: Registrations for properties and registrations for events.

Event registration /registration/event The event registration API allows an application to register an event for a data application to a specified property. This event is mapped to an MQTT pub/sub topic. By activating a subscription on one or more device(s) for that property, streaming data will get published to the associated pub/sub topic on MQTT.

NIPC Extensibility NIPC is extensible in two ways: Protocol mapping: New protocol mapping can extend NIPC with support for new non-IP protocols API extensions: API extensions leverage compound statements of basic NIPC action APIs to simplify common operations for applications.

Protocol extensions As described in NIPC supports mapping protocol specific mapping to NIPC properties. BLE and Zigbee are used as examples, but protocol mapping is extensible to other protocols, so noew non-IP protocols can be supported by NIPC without a schema change.

BLE | - BLE properties | |> Zigbee | - Zigbee properties | |> New protocol | - New protocol properties ]]>

As shown in , a protocol mapping can be added by adding a new technology specific extension to the schema. This is performed by adding the new protocol to the technology enum in the base object definition Furthermore, the protocol objects need to be extended with the new protocol as well. Protocol objects will be extended as follows: Attribute Req Type Example ble T object an object with BLE-specific properties zigbee T object an object with Zigbee-specific properties newProtocol T object an object with newProtocol-specific props In the new protocol object, protocol specific properties can be added. Protocol mappings need to be IANA registered.

API extensions /extension The extension APIs allow for extensibility of the APIs, either IANA registered extensions or vendor-specific extensions. Extension APIs must leverage the basic NIPC defined APIs and combine them in compound statements in order to streamline application operation against devices, make operations more expediant and convenient in one API call. In principle they do not add any basic functionality. In the OpenAPI model below, we have defined a few example extensions.

Publish/Subscribe Interface The publish/subscribe interface, or data streaming interface, is an MQTT publishing interface. Pub/sub topics can be created and managed by means of the /registration/event NIPC element. In this memo, we propose the data format to be CBOR .

CDDL Definition We have a CDDL definition where we define the DataSubscription struct that will be used by all the messages published to the MQTT broker. The DataSubscription struct is a CBOR map that will contain the raw data in bytes and a timestamp of the data. Optionally, the message will also have a deviceId that corresponds to the SCIM ID of the device if the payload is associated to a known device. Other fields in the CDDL such as apMacAddress and rssi can be optionally included but these fields can expose the underlying network topology. Each message also has a subscription choice group that will define the type of data that is being published.

CBOR Examples This section contains a few examples of the DataSubscription struct depicted in CBOR diagnostic notation.

Examples This section contains a few examples on how applications can leverage NIPC operations to communicate with BLE and Zigbee devices.

BLE Advertisement In this example, we will onboard a device, and setup an advertisement subscription event for that device. The sequence of operations for this are: Onboard a device using the SCIM Interface (out of scope of this memo) Register an eventc with the device id to subscribe to advertisements POST /register/event Subscribe to the topic from the data receiver app MQTT subscribe topic

BLE Property Read/Write In this example, we will connect to a BLE device and read and write from a property. The sequence of operations for this are: Onboard a device using the SCIM Interface (out of scope of this memo) Connect to the BLE device POST /action/connection Read a property from the BLE device GET /action/property Write to a property on the BLE device POST /action/property Disconnect from the BLE device DELETE /action/connection

Zigbee Property Read/Write In this example, we will connect a zigbee device to a Zigbee mesh and read and write from a property The sequence of operations for this are: Onboard a device using the SCIM Interface (out of scope of this memo) Connect the Zigbee device POST /action/connection Read a property from the Zigbee device GET /action/property Write to a property on the Zigbee device POST /action/property Disconnect from the Zigbee device DELETE /action/connection

Security Considerations TBD.

IANA Considerations This section provides guidance to the Internet Assigned Numbers Authority (IANA) regarding registration of values related to NIPC, in accordance with .

OpenAPI definition The following non-normative model is provide for convenience of the implementor.

file "openapi.yml" openapi: 3.0.3 info: title: Non IP Device Control (NIPC) API description: |- There has been a large influx of non-IP devices supporting processes in manufacturing, healthcare, hospitality, retail, the home, and the office. At the same time, wireless access points have been deployed nearly everywhere, many of which have radios that can transmit and receive different frame types, such as BLE, Zigbee. To integrate multiple of these use cases leveraging a single wireless infrastructure and avoid the need for parallel infrastructure, a Non IP device gateway function is necessary. The gateway provides the following functions: - authentication and authorization of application clients that will communicate with devices - APIs that onboard a device on the network (out of scope for this specification, but covered in SCIM for devices) - APIs that allow an app to set up a connection with a device - APIs that allow an app to exchange action with a device - APIs that allow a device to create registrations in the network for a device These collection of these APIs, in combination with the onboarding API (SCIM for devices) will allow an application to perform a complete set of operations on Non-IP devices. termsOfService: http://swagger.io/terms/ contact: email: bbrinckm@cisco.com license: name: TBD url: TBD version: 0.3.5 externalDocs: description: NIPC IETF draft url: TBD servers: - url: https://{gw_host}/nipc variables: gw_host: default: localhost description: Gateway Host tags: - name: action description: APIs that allow apps to perform actions on devices. - name: registrations description: |- APIs that allow apps to register properties of devices. - name: extensions description: |- APIs that simplify application interaction by implementing one or more basic API's into a single API call. paths: ### Action /action/connection: post: tags: - action summary: |- Connect a device to the network, optionally with service discovery description: |- Connect a device to the network, optionally with service discovery operationId: Connect requestBody: content: application/json: schema: $ref: '#/components/schemas/Connection' required: true responses: '200': description: Success content: application/json: schema: $ref: '#/components/schemas/PropertyResponse' '400': description: Bad request '401': description: Unauthorized '405': description: Invalid request '500': description: Server-side failure content: application/json: schema: $ref: '#/components/schemas/FailureResponse' get: tags: - action summary: |- Get connection state devices for a device or group of devices description: |- Get all connection status for connections made by control ap or connection status by object ID, multiple ids can be provided with comma separated strings, or a group id can be provided operationId: GetConnections parameters: - name: id in: query description: device or group ids that need to be filtered required: false explode: false schema: type: array items: type: string format: uuid example: 12345678-1234-5678-1234-56789abcdef4 responses: '200': description: Success content: application/json: schema: $ref: '#/components/schemas/MultiConnectionsResponse' '400': description: Bad request '401': description: Unauthorized '405': description: Invalid request '500': description: Server-side failure content: application/json: schema: $ref: '#/components/schemas/FailureResponse' delete: tags: - action summary: Disconnect a device or group of devices description: |- Disconnect a device or device group by object ID, Multiple ids can be provided with comma separated strings, or a group id can be provided operationId: DeleteConnections parameters: - name: id in: query description: device or group ids that need to be filtered required: false explode: false schema: type: array items: type: string format: uuid example: 12345678-1234-5678-1234-56789abcdef4 responses: '200': description: Success content: application/json: schema: $ref: '#/components/schemas/MultiConnectionsResponse' '400': description: Bad request '401': description: Unauthorized '405': description: Invalid request '500': description: Server-side failure content: application/json: schema: $ref: '#/components/schemas/FailureResponse' /action/connection/id/{id}: post: tags: - action summary: |- Connect a device by device id (device technology needs to support connection) description: |- Connect a device by device id, full service discovery will be performed.
