SD-WAN vs MPLS: The Key Differences, Explained

Unless you’re heavily involved in the world of technological networks, you probably won’t be aware of the nuances of SD-WAN vs MPLS.

Well, a high-performance, dependable vast area network (WAN) was previously only possible with MPLS. This isn’t the case anymore.

Alternatives like SD-WAN, or software-defined wide area networks, are available for today’s network.

You should consider many factors while deciding on the optimum connection solution. This includes the operational budget, the degree of flexibility required. You’ll want to consider the distance between distant branches.

So, before asking MPLS or SD-WAN, let’s take a deep dive into what makes each of them unique. Keep on reading for our full breakdown of both concepts.

What Is MPLS?

Data engineers move data packets as rapidly and effectively as feasible using the MPLS transport protocol. It’s utilized in conventional networking. In use for more than two decades now.

Organizations must physically install MPLS circuits at locations where data interchange is essential.

Think of the distant branch office and corporate data center. For example, might both have MPLS connections established for the benefit of the branch office’s users.

Predetermined data pathways are a hallmark of MPLS’ dependability and performance. If you’re moving your business to the cloud, you need a network that is more agile, adaptable, and cost-effective than ever before.

What Is SD-WAN?

It’s a software-based technique to manage the wide-area network (SD-WAN). Businesses use MPLS to link distant branches, data centers, and cloud instances. It also connects mobile devices used by workers who work from home.

A step above regular MPLS, SD-WAN is a new way to link remote locations.

Several transport techniques, such as MPLS circuits, direct internet access, and LTE/5G, are available for clients’ use. A separate transport layer simplifies and decouples the administration of the wide-area network (WAN).

More enterprises are using SD-WAN due to the increase in remote work and cloud computing. Using SD-WAN, end users can access business apps and data from any location. It also comes with greater security and reliability while enjoying a more consistent user experience.

As a result of SD-WAN, organizations may prioritize data by their specific needs and then choose the most efficient route to get it there.

General Pro and Cons of MPLS

As a general rule, MPLS provides excellent service for preventing packet loss. It’s also great for keeping an organization’s most critical traffic flowing.

As a vital feature of MPLS, it ensures that packets reach their intended locations with high levels of reliability. Real-time protocols, such as Voice over IP (VoIP), depend heavily on this level of trustworthiness.

This is feasible by the use of labels for forwarding in MPLS. The labels serve as a virtual barrier between the various types of packets.

You might give specific network traffic a higher priority by MPLS service providers. These advantages bring about predictability. Packets can only move over the specified network pathways that they’ve been assigned.

There is a monetary expense associated with MPLS. Video and augmented reality (AR) use a lot of bandwidth. And, customers may not be able to afford the expensive per-megabit costs related to MPLS because of this.

Finally, an MPLS network lacks built-in data protection. And, if constructed poorly, might expose the network to vulnerabilities.

Benefits and Drawbacks of SD-WAN

As we continue our comparison between SD-WAN vs MPLS, we can see that SD-WAN has various advantages over MPLS. SD-WAN strengthens key benefits like scalability, visibility, performance management, and scalability.

SD-WAN, unlike MPLS, does not impose bandwidth restrictions. With no infrastructure or network upgrades required, customers may effortlessly enhance their service.

For SD-WAN, the ability to cost-effectively mix and match network lines based on content type. It can also be the priority, and that’s the best selling feature of all.

Consumers may choose less costly alternatives. These are broadband internet or mobile connections for lower-priority traffic. They can keep the more expensive MPLS network for more sensitive traffic.

Security virtualization is one of SD-most WAN’s appealing features. Today’s enterprises prefer network designs that combine security, policy, and orchestration. SD-WAN security takes care of these concerns. It combines several methods for ensuring safe communication.

End-to-end encryption throughout the whole network is an advantage of the SD-WAN design. Software-defined security and scalable key exchange ensure that all devices are authorized.

SD-WAN vs MPLS: When SD-WAN Is Better

SD-WAN is an investment in the future.

Enterprises may preserve their network investment and prepare for cloud-based computing. They can also secure networking by establishing an SD-WAN architecture, as previously stated. MPLS technology doesn’t support that future since it relies on inflexible physical connections.

MPLS connection prices will continue to rise. As more costly connections are needed as more enterprises shift to the cloud and more people work remotely and access data and apps from the cloud.

Improved Performance and User Satisfaction

Thanks to SD-WAN technology, businesses can deliver more stable and high-quality connections. This works even to distant sites and edge users, including bandwidth-intensive real-time applications.

The video data packets may be routed via SD-WAN in various ways, such as the optimal path or numerous pathways. Call latency and jitter for all participants, regardless of where they are, may be reduced with this feature. You can add additional bandwidth as required using SD-flexible WAN’s provisioning capabilities.

Lower Pricing and More Options

You’ll want to transport data packets for bandwidth-intensive real-time applications. It secures several gigabit lines from carriers might be costly.

Businesses may save expenses by using SD-WAN. It gives them the freedom to choose the best possible channel for transferring data.

Using SD-WAN, a company doesn’t need to route data via its data center. They also don’t need to do so across the carrier network since they can access the cloud directly.

Depending on the situation, the best route for data packets might be wifi or 5G. Another option would be an MPLS circuit. With SD-WAN, the system may determine the optimal route on its own.

Enterprises may save money by using SD-WAN, which is another benefit. SD-WAN allows businesses to consolidate networking and security into a SASE paradigm. This way, it can be ready for the next step in digitalization.

Solid Security Protocols

MPLS is a networking technology, not a security one. Therefore, all traffic is routed to a central point where the security stack lives. Increased bandwidth costs and a bad user experience are the repercussions of this activity.

Security and networking are combined in SD-WAN, a hybrid of the two technologies. When it comes to safety, consumers have the option of choosing between on-premises and cloud-native solutions.

Even at the edge, organizations can implement security measures using SD-WAN. It guarantees that data and application traffic are safe, regardless of where it is flowing in the network.

Cloud applications may be accessed from distant branch sites and edge users. At the same time, it’ll protect them against internet-based dangers. A single security and segmentation policy may help them satisfy regulatory obligations for data.

Because no edge hardware is required at each location to provide communication, they may also lower the attack surface.

Streamlining of Business Operations

SD-automation WANs eliminate the need for human troubleshooting. Basically, it’s more straightforward for IT to adopt and administer.

Because of this, if there is a problem with the network’s equipment, the IT department will have to work quickly to fix it and redirect traffic. SD-WAN does all of the hard liftings for this task automatically.

A further benefit of SD-WAN is that it minimizes the number of onsite IT employees required at distant sites. Cloud-based, centralized administration of SD-WAN systems can give IT teams visibility and control. This makes it simpler to manage remote resources.

Special Case: MPLS May Be Superior to SD-Wan Alone 

MPLS might be a better option than SD-WAN in certain instances. For example, an MPLS connection is ideal for specific sorts of data and applications. For instance, transactions that need a high degree of integrity and anonymity.

Nevertheless, because every SD-WAN solution may use MPLS, this is not an either-or situation. MPLS may still be used for mission-critical transactions.

And in certain regions, notably in the United States, the cost of using MPLS might be prohibitive. It’s possible to save money by replacing the MPLS network with a public internet connection in certain areas.

But you may still use SD-WAN over an MPLS connection to offer better security and functionality than an MPLS solution alone. Even if MPLS is substantially less costly in comparison. Or, where security or reliability issues are more essential than cost differences.

That’s because SD-WAN offers better flexibility. It also provides more granular traffic management. Also, it’s great for integrated security, and the ability to employ connection strategies.
