SD-WAN vs Traditional WAN: Detailed Comparison & Benefits

TABLE OF CONTENTS:

Wide Area Networking (WAN) has been a cornerstone of enterprise connectivity, traditionally built on technologies like MPLS (Multiprotocol Label Switching), leased lines, and other private circuits. These networks provided reliable, secure connections between corporate offices and data centres. However, they were not without drawbacks. Traditional WANs are costly, inflexible, and complex to manage, particularly as businesses expand or migrate to cloud-based services. 

In recent years, Managed SD-WAN (Software-Defined Wide Area Networking) has emerged as a game-changing solution for modern networking challenges. Unlike traditional WAN, SD-WAN uses a software-defined approach to intelligently manage and optimise network traffic over multiple connection types, such as broadband, MPLS, and LTE, enhancing flexibility, reducing costs, and supporting cloud integration and hybrid work models. 

This blog will compare Managed SD-WAN and Traditional WAN, focusing on their key differences, benefits, and practical use cases. Understanding these aspects can help organisations make informed decisions when upgrading their network infrastructure to meet the demands of digital transformation and modern applications. 

What is Traditional WAN? 

Traditional Wide Area Networks (WANs) rely on dedicated private circuits, such as MPLS (Multiprotocol Label Switching) or leased lines, to connect branch offices, remote locations, and corporate data centres. These networks are designed to ensure secure and reliable communication by routing traffic through a centralised hub, often located at the data centre. This approach suited businesses when most applications were hosted on-premises, with limited dependency on the cloud. 

Characteristics of Traditional WAN 

Traditional WANs are known for their high reliability and the use of fixed, pre-defined paths for data transmission. MPLS networks, for instance, offer a private and predictable environment that minimises packet loss and latency. Their closed network nature provides an inherent layer of security, although additional measures such as firewalls or VPNs are often required to secure internet-bound traffic. 

Limitations of Traditional WAN 

• Cost: Traditional WANs involve significant operational and capital expenditures, including high MPLS circuit costs and maintenance of proprietary equipment. 

• Inflexibility: Scaling the network for new locations or increased workloads requires provisioning new circuits, which is time-consuming and expensive. 

• Complexity: Manual configurations for routing and troubleshooting make managing traditional WANs labor-intensive. 

• Performance: Traditional WANs are not optimised for modern cloud-based applications. Traffic is often backhauled through the data centre, leading to inefficient routing, increased latency, and degraded application performance.
