Fast Online Synchronization

Dramatically reduce synchronization time of online devices from 15 minutes to 10 seconds.

Overview

Fast Online Synchronization is a performance optimization feature that reduces the synchronization time of online devices from the traditional 15 minutes to just 10 seconds. This enables near-instant propagation of configuration changes and access rights updates to connected devices.

Available since: Version 23.03 (March 2023)

How to Use

Prerequisites

• DOMController with API v23 or later
• Online devices (RFNM, ACM with network connectivity)
• Optimized Access Control Software implementation recommended

Configuration Steps

1. Enable Fast Online Synchronization

Configure the global parameter via API:

POST /api/global-conf
{
  "fast_online_sync": true
}

1. Verify Configuration

Check the current sync interval:

GET /api/global-conf

Response:
{
  "fast_online_sync": true,
  "sync_interval_seconds": 10  // Changed from 900
}

1. Monitor Synchronization

Track sync events via logs or API:

GET /api/devices/{device_id}/last-sync

Response:
{
  "last_sync_timestamp": "2025-02-18T10:30:05Z",
  "sync_duration_ms": 340,
  "items_synchronized": 15
}
