Controller

The BNG Blaster controller provides a REST API to start and stop multiple test instances. It exposes the BNG Blaster JSON RPC API as REST API and provides endpoints to download logs and reports.

Installation

The BNG Blaster controller should run on any modern linux distribution but is primary tested on Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.

Download and install debian package: https://github.com/rtbrick/bngblaster-controller/releases

API

OpenAPI: https://rtbrick.github.io/bngblaster-controller/

Create Test Instance

PUT /api/v1/instances/<instance-name>

This API endpoint creates a test instance if not already created. The body of this request is stored as bngblaster configuration (config.json).

Each test instance creates a directory in /var/bngblaster/<instance-name>. This directory contains the following files:

config.json: bngblaster configuration
run.pid: bngblaster process ID (if running)
run.json: bngblaster arguments
run_report.json: bngblaster report (if enabled)
run.pcap: bngblaster traffic capture (if enabled)
run.sock: bngblaster control socket
run.stderr: bngblaster standard error
run.stdout: bngblaster standard output

Start Test

POST /api/v1/instances/<instance-name>/_start

The start API endpoint will start the bngblaster with the argument options defined in the body.

Status

GET /api/v1/instances/<instance-name>

The status API endpoint returns the status of the test.

Command

POST /api/v1/instances/<instance-name>/_command

The JSON body of this API call will be passed to the bngblaster instance control socket (/var/bngbnlaster/<instance-name>/run.sock). The result will be passed back to the client.

curl --location --request POST 'http://<IP>>:8001/api/v1/instances/<instance-name>/_command' \
--header 'Content-Type: application/json' \
--data-raw '{
    "command": "session-info",
    "arguments": {
        "session-id": 1
    }
}'

{
    "status": "ok",
    "code": 200,
    "session-info": {
        "type": "pppoe",
        "session-id": 1,
        "session-state": "Established",
        "...": "..."
    }
}

The result code is passed as HTTP response status code.

{
    "status": "warning",
    "code": 404,
    "message": "session not found"
}

Stop Test

POST /api/v1/instances/<instance-name>/_stop

The stop API endpoint will send the SIGINT signal to the corresponding BNG blaster instance (kill -INT <pid>).

Delete Test Instance

DELETE /api/v1/instances/<instance-name>

This API endpoint deletes the test instance directory. The corresponding test run is forcefully terminated (kill -9 <pid>) if running.
