# OpenWiFi RRM Service
[See here](owrrm/README.md) for details.
OpenWiFi uCentral-based radio resource management (RRM) service, providing a
cloud-based Wi-Fi RRM layer for APs running the OpenWiFi SDK.
## Project Structure
This is an [Apache Maven] project with the following modules:
* `lib-cloudsdk` - OpenWiFi CloudSDK Java Library
* `owrrm` - OpenWiFi RRM Service
This service collects data from OpenWiFi APs (e.g. Wi-Fi scans, stats,
capabilities) via the uCentral Gateway and Kafka, and integrates with the
OpenWiFi Provisioning service to perform optimization across configured
"venues". It pushes new device configuration parameters to APs after RRM
algorithms are run (manually or periodically).
## Requirements
* **Running:** JRE 11.
@@ -14,7 +16,7 @@ This is an [Apache Maven] project with the following modules:

$ mvn package [-DskipTests]
```

This will build a runnable JAR located at `target/openwifi-rrm.jar`.

```
Unit tests are written using [JUnit 5].
## Code Style
## Usage
```
$ java -jar openwifi-rrm.jar [-h]
```
To start the service, use the `run` command while providing configuration via
either environment variables (`--config-env`) or a static JSON file
(`--config-file`, default `settings.json`). The following data is *required*:
* Service configuration
* Env: `SERVICECONFIG_PRIVATEENDPOINT`, `SERVICECONFIG_PUBLICENDPOINT`
* JSON: `serviceConfig` structure
* Kafka broker URL
* Env: `KAFKACONFIG_BOOTSTRAPSERVER`
* JSON: `kafkaConfig` structure
* MySQL database credentials
* Env: `DATABASECONFIG_SERVER`, `DATABASECONFIG_USER`, `DATABASECONFIG_PASSWORD`
* JSON: `databaseConfig` structure
## OpenAPI
This service provides an OpenAPI HTTP interface on the port specified in the
service configuration (`moduleConfig.apiServerParams`). An auto-generated
OpenAPI 3.0 document is hosted at the endpoints `/openapi.{yaml,json}` and is
written to [openapi.yaml](openapi.yaml) during the Maven "compile" phase.
## For Developers
See [IMPLEMENTATION.md](IMPLEMENTATION.md) for service architecture details and
[ALGORITHMS.md](ALGORITHMS.md) for descriptions of the RRM algorithms.
Code is auto-formatted using [Spotless] with a custom Eclipse style config (see
[spotless/eclipse-java-formatter.xml](spotless/eclipse-java-formatter.xml)).
This can be applied via Maven (but is *not* enforced at build time):

# OpenWiFi RRM Service
OpenWiFi uCentral-based radio resource management (RRM) service, providing a
cloud-based Wi-Fi RRM layer for APs running the OpenWiFi SDK.
This service collects data from OpenWiFi APs (e.g. Wi-Fi scans, stats,
capabilities) via the uCentral Gateway and Kafka, and integrates with the
OpenWiFi Provisioning service to perform optimization across configured
"venues". It pushes new device configuration parameters to APs after RRM
algorithms are run (manually or periodically).
See [IMPLEMENTATION.md](IMPLEMENTATION.md) for service architecture details and
[ALGORITHMS.md](ALGORITHMS.md) for descriptions of the RRM algorithms.
## Usage
```
$ java -jar openwifi-rrm.jar [-h]
```
To start the service, use the `run` command while providing configuration via
either environment variables (`--config-env`) or a static JSON file
(`--config-file`, default `settings.json`). The following data is *required*:
* Service configuration
* Env: `SERVICECONFIG_PRIVATEENDPOINT`, `SERVICECONFIG_PUBLICENDPOINT`
* JSON: `serviceConfig` structure
* Kafka broker URL
* Env: `KAFKACONFIG_BOOTSTRAPSERVER`
* JSON: `kafkaConfig` structure
* MySQL database credentials
* Env: `DATABASECONFIG_SERVER`, `DATABASECONFIG_USER`, `DATABASECONFIG_PASSWORD`
* JSON: `databaseConfig` structure
## OpenAPI
This service provides an OpenAPI HTTP interface on the port specified in the
service configuration (`moduleConfig.apiServerParams`). An auto-generated
OpenAPI 3.0 document is hosted at the endpoints `/openapi.{yaml,json}` and is
written to [openapi.yaml](openapi.yaml) during the Maven "compile" phase.
