The Difference between Traditional WAN and SD-WAN

In the world of networking, there’s been a significant shift from traditional Wide Area Network (WAN) solutions to the more contemporary Software-Defined Wide Area Network (SD-WAN). As businesses grow and diversify their operations, the need for agile, scalable, and reliable network solutions has never been more pronounced. In this article, we will delve into the distinctions between traditional WAN and SD-WAN and discover why many are making the switch.

Traditional WAN

  • Centralized Control: Traditional WANs typically rely on a centralized control system. This means that any configuration changes or updates have to be done manually on each device, which can be time-consuming and error-prone.
  • MPLS Dependency: Many traditional WANs primarily rely on Multiprotocol Label Switching (MPLS) for traffic routing. While MPLS offers a consistent and reliable method of sending data packets, it can be expensive, especially for businesses with numerous remote locations.
  • Performance Limitations: Traditional WANs often struggle with ensuring optimal application performance across the network, particularly when cloud applications or unified communications are involved.
  • Limited Visibility: With traditional WAN, there is often a lack of deep visibility into the network, making it challenging to troubleshoot issues or optimize performance.

  • Dynamic Path Selection: Unlike traditional WANs, SD-WAN can route traffic across multiple types of connections, including MPLS, broadband, and 4G/LTE. This ensures that the most efficient path is always chosen for data packets, improving overall network performance.
  • Centralized Cloud-based Management: SD-WAN solutions offer centralized control through cloud-based dashboards. This allows for easy configuration, monitoring, and updates from a single location, ensuring consistency across the network.
  • Improved Performance: SD-WAN solutions use advanced algorithms to monitor the health of different paths and route traffic accordingly. This results in better application performance and a superior user experience.
  • Enhanced Security: SD-WAN solutions are typically built with integrated security features like encryption, firewall, and secure segmentation. This ensures that data remains safe as it travels across the network.
  • Cost Savings: By leveraging cheaper broadband connections and reducing the dependency on MPLS, businesses can achieve significant cost savings with SD-WAN.
