Why SD-WAN Is Replacing Traditional MPLS in Enterprise Networks

Introduction:

In today’s digital age, businesses are increasingly relying on technology to operate efficiently and stay competitive. This has led to a rise in the use of cloud-based applications, remote work, and the need for a reliable and secure network to connect all these elements. As a result, traditional Multiprotocol Label Switching (MPLS) networks are being replaced by a newer and more efficient technology called Software-Defined Wide Area Network (SD-WAN). In this blog post, we will explore why SD-WAN is becoming the preferred choice for enterprise networks over traditional MPLS.

Understanding MPLS and its Limitations:

MPLS is a telecommunications service that uses labels to direct data packets across a network. It was once considered the gold standard for enterprise networks due to its reliability and security. However, with the rise of cloud-based applications, MPLS has become increasingly expensive and inflexible.

It requires a dedicated physical network and can take weeks or even months to set up, making it unsuitable for businesses with multiple branch locations or remote employees.

The Rise of SD-WAN:

SD-WAN is a newer technology that allows businesses to connect their network using software rather than hardware. It uses a centralized controller to manage and direct traffic across the network, making it highly flexible and scalable.

This allows businesses to connect multiple locations, including remote and mobile users, using the internet or other connectivity options like 4G/5G. Moreover, SD-WAN offers several benefits over traditional MPLS networks, making it a better fit for the modern enterprise.

Cost Savings:

One of the most significant advantages of SD-WAN is the cost savings it offers. Unlike MPLS, which requires expensive hardware and dedicated circuits, SD-WAN uses existing internet connections to connect branch locations. This eliminates the need for costly equipment and long-term contracts, resulting in significant cost savings for businesses.

Additionally, SD-WAN allows businesses to use multiple internet connections simultaneously, increasing bandwidth and reducing downtime, all at a fraction of the cost of MPLS.

Enhanced Performance and Reliability:

MPLS networks are known for their reliability, but they often fall short when it comes to performance. As businesses increasingly rely on cloud-based applications, MPLS’s backhauling approach can cause delays and reduced performance.

On the other hand, SD-WAN uses intelligent routing algorithms to direct traffic across the most optimal path, resulting in faster and more reliable connections. This is especially crucial for businesses with remote or mobile employees who need to access critical applications from different locations.

Improved Network Visibility and Control:

SD-WAN offers businesses greater visibility and control over their network traffic. Its centralized controller allows for real-time monitoring and management of network traffic, applications, and devices.

This means businesses can prioritize critical applications, ensuring they receive the necessary bandwidth and performance, while non-essential applications can be directed to less expensive connections. This level of control is not possible with traditional MPLS networks, making SD-WAN a more efficient and cost-effective option.

Conclusion:

In conclusion, SD-WAN is quickly replacing traditional MPLS in enterprise networks due to its flexibility, cost savings, enhanced performance and reliability, and improved network visibility and control. With its ability to connect multiple locations, including remote and mobile users, using the internet, SD-WAN is the ideal solution for businesses looking to stay competitive in today’s digital landscape. As technology continues to evolve, it is essential for businesses to adapt and embrace new and innovative solutions like SD-WAN to stay ahead of the game.
