Cisco SD-WAN & Multi-Domain Architecture
Branch offices and remote sites need secure, high-performance connections to corporate data centers and cloud apps. Traditional MPLS-based WANs are expensive and inflexible.
Rising Bandwidth Costs
Heavy reliance on MPLS can drive up costs for large distributed networks.
Limited Agility
Adding new branches or adjusting bandwidth is slow and tedious.
Security Overlaps
Balancing direct internet breakouts with corporate security policies is complex.
Detailed Use Case
A global retail operation with hundreds of branches across multiple continents needs a cost-effective WAN solution for connecting POS systems and staff to HQ and cloud services.
SD-WAN Architecture
Dhanyaayai designs a Cisco SD-WAN overlay with a mix of MPLS, broadband, and LTE links to optimize performance and resilience.
Policy-Based Routing
Critical traffic (POS transactions) is prioritized, while less critical services use cheaper broadband routes.
Secure Internet Breakout
Branches connect directly to Cisco Umbrella for safe browsing, reducing latency and backhaul costs.
Performance Monitoring
Cisco ThousandEyes monitors end-to-end performance, quickly identifying bottlenecks.
