XConf DataService Overview

Xconf is slated to be the single entity for managing firmware on set-top boxes both in the field and in various warehouses and test environments.

Xconf's primary purpose is to tell set-top boxes (STBs) what version of firmware they should be running. Xconf does not push firmware to the STB, nor is not involved in any way in the actual download / upgrade process. It simply tells the STB which version to use. Xconf also tells STBs when, where (host), and how (protocol) to get the firmware.

Xconf DataService is the app that the STBs talk to. Xconf Admin allows humans to enter all the information necessary for Xconf to provide the correct information to STBs.

The interface between STBs and Xconf is simple. STBs make HTTP requests to Xconf sending information like MAC address, environment, and model. Xconf then applies various rules to determine which firmware information to return. The information is returned in JSON format.

Architecture

• Golang
• gorilla/mux
• Cassandra DB

Run the application

1. Run cassandra DB and create a corresponding schema using db_init.cql file in db folder.
2. Use config/sample_xconfwebconfig.conf to add/override specific environments properties.
3. Build the binary:

cd .../xconfwebconfig
make

1. Run the application:

export SAT_CLIENT_ID='xxxxxx'
export SAT_CLIENT_SECRET='yyyyyy'
export SECURITY_TOKEN_KEY='zzzzzz'
mkdir -p /app/logs/xconfwebconfig
cd .../xconfwebconfig
bin/xconfwebconfig-linux-amd64 -f config/sample_xconfwebconfig.conf

Endpoints

XConf Primary API

Headers

For /xconf/swu/{applictionType} API:
HA-Haproxy-xconf-http to indicate if connection is secure

Device Configuration Manager (DCM)

Remote devices like set top boxes and DVRs have settings to control certain activities. For instance, STBs need to know when to upload log files, or when to check for a new firmware update. In order to remotely manage a large population of devices, we need a solution that lets support staff define instructions and get the instructions to the devices.

RDK Feature Control (RFC)

Headers

HA-Haproxy-xconf-http - indicate if connection is secure
configsethash - hash of previous response to return 304 Not Modified http status

Rule Structure

There are 6 different rule types: FirmwareRule, DCM Rule (Formula), TelemetryRule, TelemetryTwoRule, SettingRule and FeatureRule (RFC Rule).

Extended from Rule object: DCM Rule, TelemetryRule, TelemetryTwoRule. It means that rule object itself has rule structure, corresponding rule fields like negated, condition, compoundParts and relation are located in root json object itself.

Otherwise there is rule field.

TelemetryRule json extended by Rule object:

Rule Object

There are following fields there:
negated - means condition is with not operand.
condition - key and value statement.
compoundParts - list with multiple conditions.
relation - operation between multiple conditions, possible values OR, AND.

Condition structure

Each condition has freeArg and fixedArg field. freeArg typed key. fixedArg value meaning.

If rule has only one condition there are no compoundParts, relation field is empty. If there are more than one condition - they are located in compoundParts object. First condition does not have any relation, next one has a relation.
