For many years, MPLS networks were the standard way to connect multiple business locations. MPLS circuits offered predictable performance and centralized routing control across private carrier networks.
As internet connectivity has improved and cloud platforms have become central to business operations, organizations are increasingly evaluating SD-WAN as an alternative.
SD-WAN allows businesses to use multiple internet connections while maintaining intelligent routing and application performance optimization.
What is MPLS Networking
MPLS stands for Multiprotocol Label Switching. It is a private carrier network that routes traffic through a provider’s infrastructure rather than across the public internet.
This approach has historically offered reliable performance, since the network path was controlled directly by the carrier.
Typical characteristics of MPLS networks include:
- Dedicated carrier circuits
- Predictable latency and packet delivery
- Centralized routing through provider networks
- High cost per location
MPLS still serves some enterprise environments well, but it often lacks the flexibility that modern, cloud-first organizations need.
How SD-WAN Provides a New WAN Architecture
SD-WAN allows businesses to build wide area networks using standard internet connections such as fibre, cable, or wireless.
Instead of relying on a single private carrier network, SD-WAN dynamically selects the best available path for traffic.
This allows organizations to combine multiple connections into a single, optimized network.
MPLS vs SD-WAN Comparison
| Feature | MPLS Network | SD-WAN |
|---|---|---|
| Connectivity type | Private carrier network | Internet-based connectivity |
| Routing control | Carrier managed | Software-defined routing |
| Cloud access | Often routed through a central data center | Direct cloud connectivity |
| Cost structure | Higher monthly circuit cost | Uses standard internet connections |
| Scalability | Requires new circuits | New sites added easily |
| Traffic optimization | Limited application awareness | Application-aware routing |
Why Businesses Transition from MPLS to SD-WAN
Several changes in technology have made SD-WAN a practical alternative to MPLS.
Cloud platforms now host many business applications, reducing the need for centralized data centers. Internet connectivity has also improved significantly, providing reliable bandwidth at a lower cost.
SD-WAN builds on these changes by providing intelligent traffic management across multiple connections.
Organizations often choose SD-WAN when they want:
- Greater flexibility in network connectivity
- Improved cloud application performance
- Simplified expansion to new locations
- Centralized control over network routing policies
- More cost-effective connectivity options
OnePort SD-WAN and Modern WAN Design
OnePort SD-WAN from Fidalia Networks combines multiple internet connections into a unified network platform, part of the broader OnePort connectivity platform.
This architecture helps organizations maintain reliable connectivity while optimizing application performance across offices and cloud platforms.
Fidalia’s managed service approach also includes proactive monitoring and network management, so businesses can maintain high performance without managing complex WAN infrastructure internally.
