WAN Architecture Design and Optimization
Design optimized multi-site WAN architectures with cost analysis and risk assessment
What You Can Do
You can evaluate WAN technologies (MPLS, SD-WAN, DIA, broadband), design resilient multi-site architectures, perform detailed cost-benefit analysis, and assess technology and operational risks. Claude helps you create comprehensive network design recommendations with topology diagrams, technology comparisons, ROI projections, and implementation roadmaps tailored to your business requirements and constraints.
Features
Create optimized network layouts for 2-100+ locations with hub-and-spoke, full-mesh, or hybrid topologies based on traffic patterns and business requirements.
Compare MPLS, SD-WAN, DIA, broadband, 4G/5G, and hybrid approaches across performance, cost, security, and scalability dimensions.
Project capital and operational expenses, calculate payback periods, and model 5-year TCO scenarios for different architectural approaches.
Identify single points of failure, design redundancy strategies, model failure scenarios, and quantify business impact of network outages.
Right-size links based on traffic forecasting, QoS requirements, and growth projections while minimizing costs and latency.
Design WAN security zones, recommend placement of firewalls and DLP, and align network design with security compliance requirements.
Develop phased migration plans from legacy networks, minimize disruption windows, and define success metrics for transitions.

Key Recommendations:
- Deploy SD-WAN for branches, retain MPLS for critical sites
- Implement dual-ISP at all locations, triple-redundancy at DCs
- Estimated savings: $450k over 5 years vs. current MPLS-only design
- Go-live in phases: DC first (month 1), branches (months 2-3), remote sites (month 4)
