100-Terabit Core Network Quality Assurance
A Major Telco Provider embarked on a major upgrade of its national backbone, introducing 100-Terabit IP/MPLS systems to support growing demand across broadband, TV, mobile, and 5G services.
Plexinor Technologies partnered with the carrier to deliver end-to-end quality assurance, ensuring the new high-capacity platform was validated, stable, and ready for production rollout.
The Customer Challenge
The carrier needed to:
Deploy a next-generation core capable of supporting massive traffic growth
Ensure operational stability during the transition
Test and validate new hardware, features, and capacity profiles
Identify issues early and avoid service-impacting failures
Maintain very high availability during upgrade cycles
A structured, repeatable, and engineering-led QA process was required to verify performance and readiness before integration into the live network.
Plexinor’s Role
Plexinor Technologies was appointed to perform full quality control and validation for the new 100-Terabit systems.Our engineers worked closely with the customer’s network engineering and test teams to build a reliable assurance framework.
We delivered:
A tailored system-level test plan based on the target architecture
End-to-end execution of functional, performance, and stability tests
Rapid defect identification, reporting, and fix-validation cycles
Collaborative support with vendor and customer teams to resolve issues
Assurance that the platform met operational expectations prior to rollout
Delivery Approach & Technical Execution
Our quality engineering process followed a structured and collaborative workflow:
Tailored Test Plan Creation
A custom QA plan was produced to align with the project scope, including:
Core routing functionality validation
MPLS behaviours and forwarding validation
Platform and line-card capability verification
High-availability and failover testing
Traffic-load and throughput checks
End-to-End Test Execution
We executed tests across all relevant scenarios, ensuring hardware and software stability under realistic service conditions.
Issue Identification & Fix Verification
Where defects were discovered:
Details were logged and escalated
Vendors and engineering teams collaborated on fixes
Plexinor re-tested and validated corrections
Retests ensured expected behaviour and operational readiness
Collaborative Engineering Support
Our team worked closely with customer stakeholders to maintain clear communication, transparent reporting, and fast feedback loops.
Outcomes and Business Impact
Through structured testing and disciplined execution, Plexinor enabled the customer to:
Introduce a next-generation 100-Terabit backbone with confidence
Minimise operational risk during deployment
Validate the performance and resilience of new IP/MPLS systems
Maintain high availability while transitioning to a modern platform
Prepare the backbone for future service growth across broadband, TV, mobile, and 5G
The result is a carrier-grade, high-capacity core network aligned to the operator’s long-term demands.
Conclusion
Plexinor Technologies delivered the quality assurance foundation required for a major national carrier to deploy one of its most significant backbone upgrades.Our structured approach, rapid issue handling, and close collaboration ensured a smooth and reliable introduction of the new 100-Terabit architecture.
