Implementation Timeline
4 Months
A regional bank with 18 branch offices and 400+ employees faced recurring network outages that directly impacted customer service, ATM availability, and core banking operations. Legacy WAN infrastructure lacked redundancy and relied on a single primary connectivity path that created single points of failure.
The bank required a solution that could provide enterprise-grade reliability without requiring significant capital expenditure on new infrastructure.
The Challenge: Network Outages Impact Revenue
- 1
Unplanned Downtime
Network outages occurred 2-3 times monthly, lasting 30-90 minutes each. During these periods, branch staff couldn't process transactions, ATMs went offline, and customer calls went unanswered.
- 2
Single Point of Failure
All branches relied on a single fiber connection to the headquarters data center. A single fiber cut or provider outage affected all locations simultaneously.
- 3
Bandwidth Bottlenecks
Transaction processing, online banking, and video conferencing competed for limited bandwidth. Peak hours saw significant performance degradation.
- 4
Manual Failover Processes
When outages occurred, IT staff had to manually redirect traffic, a process that took 15-20 minutes and extended downtime impact.
Business Impact: Each 30-minute outage resulted in lost transaction fees, customer dissatisfaction, and regulatory compliance concerns. The bank estimated annual losses at $150,000+ from downtime-related issues.
The Solution: SD-WAN with Multi-Path Redundancy
Nubiscore Networks designed and deployed a carrier-grade SD-WAN solution that consolidated multiple connectivity paths and added intelligent failover capabilities.
Multi-Path Connectivity Architecture
Each branch was connected through:
- Primary: Fiber connection to headquarters
- Secondary: Business-grade broadband backup
- Tertiary: LTE failover for critical sites
Intelligent Traffic Steering
SD-WAN continuously monitors each path for latency, packet loss, and availability. When degradation is detected, traffic automatically shifts to the healthiest path without manual intervention, typically within seconds.
Application-Aware Optimization
Transaction processing applications receive prioritized bandwidth, while less critical traffic (backup jobs, updates) is deprioritized during peak hours.
Centralized Management & Monitoring
A single dashboard provides real-time visibility into all branch connectivity, application performance, and automated alerting for proactive issue prevention.

Key Learnings & Recommendations
Multi-path redundancy is non-negotiable for mission-critical operations
A single connectivity path creates unacceptable business risk. SD-WAN enables cost-effective redundancy by intelligently using diverse carriers and technologies.
Automatic failover eliminates human error and response time
Manual failover processes introduce unacceptable delays. Automated intelligent routing ensures immediate recovery without operational intervention.
Application-aware optimization improves user experience and efficiency
Not all traffic has equal business importance. Intelligent prioritization ensures mission-critical transactions always receive optimal performance.
Centralized management simplifies operations at scale
Managing 18 distributed locations through a single dashboard reduces complexity, improves visibility, and enables proactive problem prevention.
