Stories

Customer Service Operations

• Ops Web Interface
  build a javascript or equiv web page with an MQ client subscribing to the MQ server.

Platform services:

• SoftwareManifest Management

  • add software artifacts, manage deploy sets, query for the deploySet for a DeviceHost

• Configuration Management (handshake values for a DeviceHost)
  Manage handshake values like the tablet does

• Credential management
  Api to get associations of alias, key, allowed packages

• Content Management

  • provide list of content to download and cache for local apks and venue devices. Like tablet content calls.
  • associate name,value pair lists to each content item to provide info regarding usage and deployment

Device Host

• Volley client

  • create support library for platform REST calls and JSON result parsing
  • incorporates jsonWebToken logic for Cheerios
  • client implements generics to simplify and codify usage norms in apps

• LockboxProvider : firmware specific storage for credentials and secrets to be securely distributed to appropriate apps.
  Provisioning can occur before any targeted apps are installed on a device. Highly sensitive data must be stored in the event keydata is required to establish network connectivity (wifi certificates, pre-shared keys , etc). This provider is embedded in firmware and is responsible for securely storing and dispensing keys to the designated apps when they request them. This flow is designed to allow white-label deployments in addition to our internal deployment.

• DeviceAdmin : customization for the BridgeReceiver
  BridgeReceiver is carrying forward the SERI model of interaction through Broadcasts. The broadcasts are not secured. Anyone through app or adb can send a broadcast and trigger our system level events. Broadcasts should be secured by permission or a calling package whitelist.

  • refactor to a secure calling model

• Warehouse Setup/ copy

• update calls to download content and apks during provisioning or post provision stages
• enable Json / Cheerios format calls

• ManagedProvisioning :
  • wireless Out-of-Box configuration stage (Aurora mode)
  • convert to use cheerios calls

BTHost / Core

• MQ Client to Platform MQ Broker
  ICC replacement connection. Use MQTT on the device-host side connecting to RabbitMQ on the datacenter side.

• ConfigurationProvider

  • retrieve / store handshake settings
  • retrieve / store secure configuration data (url's, etc)
  • retrieve / store manifest/software installation details

• Platform Upkeep Manager
  Performs the work of downloading apps and content described in Configuration manifests. Prunes unneeded content and apps, caches preferred content and apps.

  • Config/Software/Content : update/download/install/notify

  • Create cache mechanisms for content

  • Create cache mechanism for apks to enable branch switching in DEV mode

  • JobScheduler / tracker
    Sets up and tracks periodic upkeep that should happen

    • Download manager tracking and pacing

• Service tracker
  Starts and tracks services that should be running on the system. Specify Categories for activities and Services that indicate the timeline for

Host Services:

• FieldService messaging
  Create an extensible mechanism to receive MQ messages from PlatformMQ, execute status checks & operations and return the results through the PlatformMQ

• MediaContentProvider
  Work with Game/DIning teams to define

  • insert/remove content, garbage collection, downstream notifications (more sophisticated than upkeep mgr)

• Software Download Manager / Installer
  During the build process, manifest will be created (json) describing the deployment targets (sitehost, tablet, etc), the binary runtime artifacts and their binary runtime dependencies and content uri's.

  • The installer will be responsible for double-checking the runtime dependency lists prior to installation to verify that when an apk is installed it will immediately be usable.
  • get manifest declaration from runtime components and dependencies
  • stop all runtime dependency apps
  • up/downgrade apks to target version
  • identify and launch startup tasks and services.

Tablet Host Software

• Beacon / Tablet status
  • UDP Connection
  • MQ Broker for beacon / hive
  • Spread ?
• Hive commands
  • connect to Ops Web IF
  • deliver to tablets
• SIteConnection
  • UDP connection to transmit messages to and from game engines and game renderers.
• HTTP server to provide apks and content to tablet devices.
  • configuration options, port mapping
  • mechanism to work with file content providers (translate url's to content Uri's)

Game Host

• insure that MediaContentProvider is capable and compliant with the needs of game host apps.
• provide notification methods to trigger packages when content changes.
