From MPLS to SD-WAN

Intercloud.Aug 21, 2024

Navigating the transition

As digital demands surge, businesses are under pressure to ensure their networks are both adaptable and robust. Many are finding that traditional technologies like MPLS (Multiprotocol Label Switching) struggle to keep up with modern, cloud-driven environments. Designed for a time of predictable, centralized data traffic, MPLS now faces challenges in supporting today’s decentralized enterprises. This is where SD-WAN (Software-Defined Wide Area Network) steps in. By using software to manage application traffic and IP packets, SD-WAN enables businesses to adapt more easily to changing needs while reducing costs. As digital transformation accelerates, SD-WAN is quickly becoming the preferred solution for building smarter, more efficient networks. However, this shift requires careful planning and strategic consideration.

Key differences between MPLS and SD-WAN

MPLS is a protocol designed to accelerate data transmission across wide area networks (WAN) by routing traffic based on short path labels rather than long network addresses. While MPLS offers reliability and the ability to prioritize traffic types, it also has limitations, especially when it comes to meeting the demands of modern, cloud-first business environments.

On the other hand, SD-WAN (software-defined wide area networking) is a technology that decouples network control from hardware, using software to intelligently route IP address-based traffic across multiple WAN connections. This approach offers dynamic path selection, which is crucial for businesses that rely heavily on cloud applications, mobile workforces, and IoT devices.

Why are enterprises shifting to SD-WAN?

While MPLS has long been a trusted solution for secure and reliable networking, it struggles to keep up with the demands of modern, cloud-first operations and widespread remote workforces. Today’s business environment requires a network that can adapt quickly to change, scale with growing needs, and do so cost-effectively. SD-WAN solutions are now the preferred choice for enabling flexible, high-performance networks that can handle diverse application traffic across multiple locations. By seamlessly integrating with cloud-based applications and optimizing user experience, SD-WAN not only enhances operational efficiency but also reduces costs, making it an attractive choice for forward-thinking organizations.

Advantages of SD-WAN

SD-WAN offers several key advantages that make it a compelling alternative to MPLS:

  • Flexibility: SD-WAN is designed to be highly adaptable, accommodating the evolving needs of businesses. Whether integrating new applications, supporting remote sites, or managing a mobile workforce, SD-WAN adjusts effortlessly to these changes.
  • Cost savings: By utilizing cost-effective broadband internet instead of relying on expensive MPLS circuits, SD-WAN significantly cuts networking costs while maintaining high performance.
  • Improved performance: Through intelligent traffic management, SD-WAN ensures that critical applications receive the bandwidth they need, optimizing overall network performance and ensuring smooth, uninterrupted operations.
  • Simplified management: SD-WAN centralizes network management, providing enterprises with a unified view of the entire network. This centralization simplifies troubleshooting, enhances visibility, and allows for more efficient network management.
  • Avoiding vendor lock-in: SD-WAN offers the flexibility to design a WAN tailored to specific business needs without being tied to a single service provider. This freedom ensures that businesses can adapt their networks as they grow, scaling bandwidth and services without significant infrastructure changes.

Key considerations when switching to SD-WAN

While the benefits of SD-WAN are clear, transitioning from MPLS presents several challenges that enterprises must carefully navigate to ensure a successful migration:

  • Security concerns: Unlike MPLS, which typically operates over private, dedicated circuits, SD-WAN often uses public internet connections to route traffic. This shift increases exposure to potential security threats. To mitigate these risks, enterprises must implement robust security measures, such as end-to-end encryption, next generation firewalls, and comprehensive monitoring tools, to protect sensitive data and maintain compliance with industry regulations.
  • Deployment complexity: Deploying SD-WAN can be particularly complex in large, geographically dispersed environments. The process involves reconfiguring network architecture, establishing new routing protocols, and ensuring seamless connectivity across multiple sites—all while maintaining uninterrupted business operations. Due to this complexity, careful planning is essential. Many organizations choose to engage external expertise to guide the deployment, manage challenges, and ensure a smooth transition.
  • Infrastructure compatibility: Many organizations rely on legacy hardware that may not be compatible with SD-WAN. This may necessitate costly and time-consuming upgrades or replacements. A thorough assessment of current network components is crucial.
  • Transition management: Moving from a legacy infra to a brand new technology, mainly, but not exclusively based on public transport layers, is not an easy task.  To ensure smooth transition, continuity of service and limit overlapping infrastructure and costs, a flexible, on-demand connectivity solution is required during that phase.
