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 Use cases in building management, healthcare, workplaces, manufacturing, logistics and hospitality have introduced low-power devices into these environments. These devices typically do not support IP-based interfaces, hence there is a need for gateway functions to allow these devices to communicate with the applications that manage them.

| Gateway |<------------>| Non-IP | | app | IP-based | | Non-IP | Device | +-------------+ Operation +---------+ Operation +--------+ ]]>

In abscence of a standard describing how applications communicate with such non-IP devices, vertically integrated infrastructure prolifilates and applications have bespoke integrations with that infrastructure for every use case. The Application interfaces are non-standard. This stunts the eco-system growth. At the same time, wireless access points have been deployed nearly everywhere, many of which have soft or separate radios that can transmit and receive different frame types, such as and . To avoid the need for parallel infrastructure and bespoke application integration, a standardized gateway function is necessary. The gateway provides at a minimum the following functions: authentication and authorization of application clients that will access devices the ability to onboard devices that are intended to be deployed within the use case maintenance of an inventory of onboarded devices that are intended to access and be accessed by the deployment and applications. interfaces that allow for bi-directional communication to non-IP devices one or more channels to process requests, responses, and asymmetric communciations with the non-IP radio resources (Access Points) in the system. Combined with a provisioning interface such as , this specification supports these aspects, specifically focusing on providing bi-directional communication with non-IP devices.

shows us the application layer gateway (ALG), an access point (AP), and a device (D) in the enterprise environment. The role of the ALG is to provide a application gateway to non-IP devices connecting into one or more AP. Applications implementing this memo can leverage RESTful interfaces to communicate with these devices and subscribe to streaming data or broadcasts levering MQTT. The flow of operations are as follows: The operator of the network deployment 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:
a. Authorize an onboarding application against a SCIM endpoint supported by the gateway.
b. Provision and authorize applications that may control devices.
c. Provision and authorize applications that may receive telemetry. The authorized application can now provision one or more devices on the gateway leveraging SCIM. Steps 1 and 2 are not within the scope of this specification, but are provided for context. The authorized application can perform RESTful calls to the gateway in order to establish bi-directional communication to one or more devices. Optionally, set up a publish/subcribe topic to receive streaming data from a device (telemetry interface). Optionally, an application can receive streaming data on a pub/sub topic configured by the control interface (telemetry interface). Step 3 and 4 are the subject of this memo. This specification is organized into three sections: Basic non-IP control functions described in narrative. Extensibility of the interfaces. A specification that can be mapped to a publication/subscribe interface, such as MQTT. Examples of use cases leveraging both BLE and Zigbee-based devices. OpenAPI definitions for the control interface and Protobuf definitions for the streaming data 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.

Non-IP Control Functions This section will describe a standardized protocol-agnostic interface that allows the application to establish bi-directional communication with a non-IP device, such as a BLE or Zigbee device. The interface will be supported on a gateway as show in .

Approach In non-IP protocols such as BLE or Zigbee, a number of basic operations are defined that are similar across protocols. Examples of this are read and write data. Devices may choose to implement all of the operations or a subset. For example in BLE a device may choose to implement a binding, but could also allow connection without a binding. In this memo we have therefore defined a control interface that exposes these basic operations with a communications protocol-agnostic schema, with protocol specific extensions to transmit and receive attributes that are specific to the communications protocol supported by the device. This enables extensions to integrate new non-ip communications protocols, without the need to update the base schema.

BLE | - BLE attributes | |> Zigbee - Zigbee attributes ]]>

As shown in , the control interface addresses device and group objects as IDs, hence the requirement to declare a device to the gateway before addressing a NIPC operation to the device. This is done by means of SCIM. A NIPC operation can either be performed against a device-id or a group-id. The gateway will leverage information from the SCIM object to execute a specific NIPC operation. For example, keying material found in the SCIM object may be required to connect to a device. Please refer to for more information on SCIM device objects. Apart from enabling bi-directional communication with non-ip devices, NIPC also allows an application to register pub/sub topics in order to support a programmable data streaming interface.

Common base schema As described, most operations are executed against a device or a group. Control 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 technology F enum ble where- id is the id returned in the response when registering a device against a SCIM server. type is either "group" or "device". technology is the radio technology extension(s) supported by the device, in this memo either "ble" or "zigbee".

Protocol extensions An object can support one or more communications protocols. These attributes 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 attributes that are specific to the BLE protocol. "zigbee" is an object containing attributes that are specific to the Zigbee protocol. Other protocol extensions can be added

Response As most operations have a common base schema, so do responses. As mandatory, a status is returned, optionally also device id and request id. 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 Failure response: Attribute Req Type Example status T enum SUCCESS errorCode T int 12 reason T string "Not Found" requestID F uuid abcd0987-1234-5678-1234-56789abcdef4 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

Categories of operations supported The common operations are categorized in common categories that describe high level sets of functionalities. Each of the NIPC operations belong to a category. The categories are: /connectivity: Allows an application to establish connectivity with a device (if so required by the technology) /data: Allows applications to exchange data with a device /registrations: Allows an application to make registrations in the network, for example to register a pub/sub topic /extensions: This is a category of operations that leverage basic connectivity, data or registration operations, but are optimized for application usage, allowing applications to perform functions with a reduced number of round-trips. An example of this is the the bulk operation, allowing to send multiple operations is one operation. This category also allows for further extensions based on the basic operations.

Connecting to the Non-IP Control Interface NIPC makes use of RESTful HTTP. The connection endpoint is provided out of band, most likely through the SCIM devices model extension, in which an authorized application can be registered for a SCIM object. Similarly authentication of the interface can be specified using that SCIM interface. It may be based on a device certificate or an authorization token.

NIPC Extensibility NIPC is extensible in two ways: Protocol extensions: Protocol extensions can extend NIPC with support for new non-IP protocols interface extensions: Interface extensions allow extensions that leverage compound statements of basic elements to simplify common operations for applications.

Protocol extensions As described in the NIPC interface supports protocol specific extensions that allow bi-directional communication of attributes that are specific to the protocol supported by the device. This allows for extensions to the schema to integrate new non-ip communications protocols, without the need to update the base schema.

BLE | - BLE attributes | |> Zigbee | - Zigbee attributes | |> Protocol extension | - Protocol extension attributes ]]>

As shown in , a protocol extension 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 objext 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 attributes zigbee T object an object with Zigbee-specific attributes newProtocol T object an object with newProtocol-specific attr In the new protocol object, protocol specific attributes can be added.

Interface extensions /extensions The interface extension elements are freely extendible interfaces. These elements leverage the basic NIPC defined elements 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, and we will describe them here at a high level to provide some context on other possible extensions.

Write file /extension/write/file This extension make use of multiple write operations (attribute post) to write an entire file to an attribute. The interface allows the application to define the chunk size. Operations: Write file: POST

Read conditional file /extension/read/conditional This extension performs a read operation sequentially for a defined amount of time until a specified value is read. Operations: Read Conditional: POST

Bulk /extension/bulk This extension allows you to create a compound operation made out of multiple connection and data operations that are to be executed sequentially until they all succeed or there is a failure. Supported operations are: /extension/connection/create /extension/connection/delete /extension/attribute/read /extension/attribute/write /extension/attribute/write/file /extension/attribute/write/blob /extension/attribute/read/conditional Operations: Bulk: POST

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 /register/topic NIPC element. In this memo we propose the data format to be protocol buffers, as fully described in the protobuf definition.

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 topic for that device. The sequence of operations for this are: Onboard a device using the SCIM Interface (out of scope of this memo) Register a topic with the device id to subscribe to advertisements POST /register/topic Subscribe to the topic from the data receiver app MQTT subscribe topic

BLE Attribute Read/Write In this example, we will connect to a BLE device (BLE device does not require binding) and read and write from an attribute 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 /connectivity/connection Read an attribute from the BLE device GET /data/attribute Write to an attribute on the BLE device POST /data/attribute Disconnect from the BLE device DELETE /connectivity/connection

Zigbee Attribute Read/Write In this example, we will bind a zigbee device to a Zigbee mesh and read and write from an attribute The sequence of operations for this are: Onboard a device using the SCIM Interface (out of scope of this memo) Bind the Zigbee device POST /connectivity/binding Read an attribute from the Zigbee device GET /data/attribute Write to an attribute on the Zigbee device POST /data/attribute Disconnect from the Zigbee device DELETE /connectivity/connection

Security Considerations TBD.

IANA Considerations TBD.

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 data 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: 2.0.0 externalDocs: description: NIPC IETF draft url: TBD servers: - url: https://{gw_host}/nipc variables: gw_host: default: localhost description: Gateway Host tags: - name: connectivity description: APIs that allow apps to manage device connections - name: data description: |- APIs that allow apps to exchange data with non-IP devices - name: registrations description: |- APIs that allow apps to make registrations in the network for devices. - name: extensions description: |- APIs that simplify application interaciton by implementing one or more basic API's into a single API call. paths: ### Connectivity /connectivity/connection: post: tags: - connectivity summary: |- Connect a device to the network, optionally with service discovery description: |- Connect a device to the network, optionally with service discovery operationId: connConnect requestBody: content: application/json: schema: $ref: '#/components/schemas/Connection' required: true responses: '200': description: Success content: application/json: schema: $ref: '#/components/schemas/ServiceResponse' '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: - connectivity 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: - connectivity 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' /connectivity/connection/id/{id}: post: tags: - connectivity 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.
