OpenVault Vantage – Automated Actions to Improve Broadband Network Performance & Extend the Life of Your DOCSIS® Network
OpenVault Vantage is a network optimisation software platform that aggregates real-time broadband telemetry to automate network maintenance and capacity management. The software is vendor-agnostic and functions across hybrid network footprints via a single management interface.
Core Functional Modules
Proactive Network Maintenance (Vantage PNM)
Automates the detection and location of physical layer impairments using CableLabs and SCTE standards.
- Correlated Impairment Mapping: Groups modems exhibiting identical RF degradation patterns to isolate the specific node, tap, or drop causing the issue.
- Automated Diagnostics: Analyzes upstream and downstream telemetry to generate precise repair recommendations for field technicians.
- Predictive Threat Identification: Evaluates historical subcarrier data to flag failing plant components up to 48 hours before service degradation occurs.
Profile Management Application (Vantage PMA)
Maximizes capacity on DOCSIS 3.1 and 4.0 OFDM and OFDMA channels.
- Dynamic Profile Generation: Continuously tracks modulation error ratio (MER) data across all subcarriers.
- Modulation Optimization: Assigns optimized profiles to individual cable modems based on actual line conditions.
- Capacity Enhancement: Restores up to 40% of lost network efficiency by maintaining higher modulation orders in noisy plant environments.
Congestion Management
Manages network capacity constraints caused by peak traffic volume.
- Real-Time Detection: Monitors interface utilization to detect localized micro-congestion events.
- Dynamic Bandwidth Allocation: Applies automated fair-share scheduling algorithms to manage heavy users during peak intervals.
- QoE Stabilization: Stabilizes packet delivery and latency metrics without enforcing hard, static data caps.
Operational & Economic Metrics
Field deployment data indicates the following operational outcomes:
- Repeat Field Visits: Reduced by 50% through accurate root-cause identification on the first truck roll.
- Onsite Resolution Velocity: Improved by 22% via targeted diagnostic panels that eliminate manual RF tracing.
- Critical Alerts: 15% reduction in high-priority network alarms due to automated closed-loop optimization.
