Are you facing challenges with your network infrastructure or strategizing a move to the cloud? If you haven’t explored the benefits of Software-Defined Wide Area Network (SD-WAN) yet, now might be the perfect time. SD-WAN, delivered via the cloud, offers streamlined network operations and reduced capital expenditure. Businesses worldwide are increasingly adopting SD-WAN solutions. According to projections by the International Data Corporation, the SD-WAN market is expected to reach $8 billion in the next five years.

So, what sets SD-WAN apart from traditional WAN? Let’s delve into the comparison.

How Traditional WAN Works

Traditional WAN has been the go-to choice for data networking, voice, and IT infrastructure for a considerable time. It serves to connect organizations with multiple offices across different locations. Traditional WAN solutions typically combine leased and public lines, fortified by Virtual Private Networks (VPNs) or MPLS (Multiprotocol Label Switching) routers for added security. MPLS ensures efficient and resilient traffic flow, enabling data traffic prioritization and supporting services like video and VoIP (Voice over IP).

Limitations of Traditional WAN

Traditional WAN installation and management are cumbersome, involving the procurement and installation of proprietary circuits, which proves to be laborious for IT teams. Additionally, WAN network security relies on access control lists and IP blocklists, necessitating extra hardware for setting up branch offices in remote locations. Furthermore, scaling traditional WAN is challenging, requiring extensive planning.

How SD-WAN Works

SD-WAN abstracts numerous network layer functions into software, deployable as an overlay atop existing infrastructure. It adopts a comprehensive approach to wide-area networking and can coexist with traditional WAN architecture. By leveraging internet and cloud capabilities, SD-WAN enables dynamic interconnection between branch offices and headquarters.

Advantages of SD-WAN

SD-WAN offers cost-efficient circuitry, reducing internet costs and providing flexibility in bandwidth upgrades. Unlike traditional architectures, SD-WAN can directly route cloud traffic to endpoints, optimizing network performance. Additionally, SD-WAN prioritizes critical applications across the WAN and provides real-time traffic monitoring.

Limitations of SD-WAN

Despite its advantages, SD-WAN has limitations. Its performance relies on underlying circuits, especially concerning cheap broadband. Achieving true Quality of Service (QoS) requires robust network infrastructure.

Adopting SD-WAN

SD-WAN solutions can be deployed in-house or managed by third-party services. Hybrid WAN models integrating current infrastructure with SD-WAN are also viable options.
