ISP Core & BNG Modernization
Challenge: Growth in subscribers and traffic created pressure on the existing core and subscriber edge.
Engineering: Reviewed routing, BNG/AAA placement, QoS and capacity boundaries, then mapped a staged migration path.
Focus: Scalability, failover, observability and controlled change windows.
Multi-Upstream BGP Design
Challenge: An operator needed clearer routing policy and resilient upstream connectivity.
Engineering: Designed eBGP sessions, prefix filtering, local preference, MED/communities where applicable and failover policy.
Focus: Predictable routing behavior and easier troubleshooting.
High-Traffic QoS Optimization
Challenge: Peak utilization affected latency-sensitive services during congestion.
Engineering: Reviewed traffic classes, queue hierarchy, reserved capacity and the cost of packet classification.
Focus: Performance without unnecessary router CPU overhead.
Redundant L2 Uplinks
Challenge: A site had fiber and wireless uplinks and needed automatic backup while keeping the service layer at Layer 2.
Engineering: Planned VLAN consistency, trunking and spanning-tree behavior across both sides.
Focus: Deterministic failover and loop avoidance.
Enterprise WAN Resilience
Challenge: Distributed branches required better WAN continuity and centralized policy.
Engineering: Reviewed primary/backup links, routing domains, segmentation and monitoring.
Focus: Availability and operational visibility.
ISP Platform & NMS Deployment
Challenge: An operator needed subscriber management, monitoring and service visibility across a growing network.
Engineering: Planned platform deployment, RADIUS integration, SNMP monitoring, dashboards and operational access.
Focus: Reliable operations, centralized visibility and maintainable workflows.
NOC Visibility Improvement
Challenge: Multiple network platforms made fault isolation and capacity tracking difficult.
Engineering: Structured SNMP, syslog, interface health and service-level monitoring around operational needs.
Focus: Faster detection and clearer incident response.
