Nexus Insight NMS

A cloud-native network management system for small-cell fleets: device, fault, performance, and configuration management with northbound integration.

Flagship NMS · operator deployments

Overview

Nexus Insight NMS is Nybsys’ network management system for 4G LTE small cells. I worked across most of it: the TR-069 auto-configuration server, fault, performance and configuration management, northbound integration, and the Kubernetes platform it runs on in operator networks, including the GP deployment.

Architecture

Kubernetes

01 Network

  • 4G LTE small cells

02 Management

  • Auto-configuration server
  • Fault · performance · configuration
  • File ingest & inventory

03 Data

  • Device & fault data
  • Performance time series
  • Message queues

04 Northbound

  • SNMP traps
  • Scheduled exports
  • Web portal & map
Simplified view of the parts I worked on.

What I did

01 Telecom protocols & OSS

  • Built a TR-069 auto-configuration server in Python, with device connectivity tooling and firmware upgrades.
  • Added SNMPv3 support and fault traps for northbound systems, validated against real radios.
  • Worked across fault, performance, configuration, and inventory management: scheduled data exports, historical reports, alarm synchronization, and device health alarms.
  • Added bulk configuration for groups of sites, plus device grouping, configuration backup, and remote operations.
  • Built northbound delivery of performance data to operators’ systems.

02 Kubernetes & operations

  • Wrote the Kubernetes deployments, staged and tested them, and documented how to build the cluster.
  • Set up TLS ingress, cluster DNS, and multi-network pods for operator environments.
  • Resolved networking and capacity issues in operator networks.
  • Built device monitoring with Prometheus. Log dashboards with Grafana and Loki are in progress.
  • Improved service resilience with async processing, message-queue recovery, and retry handling.

03 Scale & quality

  • Scaled file transfer and device data storage, and started load testing the auto-configuration server.
  • Built a base-station traffic simulator to exercise the NMS without real hardware.
  • Wrote the NMS training material for the team.
