SD-WAN Architecture

Key Components of SD-WAN Architecture:

Virtual Overlay

The architecture’s virtual overlay separates the physical network connections, enabling enterprises to retain existing WAN links while centralizing network control. This abstraction allows administrators to write rules and policies that can be deployed across the entire network at once.

Control Plane

The control plane is located centrally, often at an organization’s headquarters, to enhance network oversight and response. It separates from hardware, streamlining network management and elevating service delivery and user experience. The central SD-WAN controller dictates the function of SD-WAN appliances, reducing the need for individual gateway or router management.

SD-WAN Gateways

SD-WAN gateways, compatible with hybrid WAN, enable branch appliances to sustain multiple connections through diverse transport mechanisms such as MPLS, broadband internet, and LTE. These gateways establish a virtual private network (VPN) across each WAN connection, enhancing security.

Regarding the types of SD-WAN architecture, there are three main categories. On-Premises SD-WAN involves deploying the SD-WAN hardware on-site, providing direct and secure access and control over the network and hardware. Cloud-Enabled SD-WAN connects to a virtual cloud gateway over the internet, improving network accessibility and facilitating integration with cloud-native applications. Lastly, Cloud-Enabled with Backbone SD-WAN adds an extra layer of security by connecting the network to a nearby point of presence (PoP) such as a data center, enabling traffic to shift from the public internet to a private connection.

SD-WAN v.s. Traditional MPLS

SD-WAN and traditional MPLS (Multiprotocol Label Switching) are two distinct approaches to wide area networking, each with its own benefits and drawbacks.

SD-WAN decouples the network control plane from the physical infrastructure, providing flexibility and agility in network management. It can utilize various connection types, including broadband, LTE, and MPLS, to create a secure and optimized network.

In contrast, MPLS operates on a dedicated network infrastructure, offering predictable performance and quality of service (QoS) guarantees. MPLS networks are typically managed by service providers, and traffic is routed based on predetermined labels assigned to packets.

SD-WAN offers several advantages over traditional MPLS:

Cost

SD-WAN can be more cost-effective than MPLS, as it allows organizations to leverage less expensive broadband connections while still ensuring reliable and secure connectivity. MPLS, on the other hand, often comes with steep bandwidth costs.

Flexibility

SD-WAN provides greater flexibility in terms of connection types and network configurations. It can adapt to the dynamic nature of modern networks and support interconnectivity between branch offices more effectively than MPLS. MPLS connections tend to be fixed, lacking the ability to easily adapt to changing network requirements.

Performance

SD-WAN offers enhanced performance by recognizing and prioritizing different types of traffic. It can dynamically adjust bandwidth and provide granular load balancing between multiple connections, ensuring that latency-sensitive applications receive the necessary resources. MPLS, while reliable, may not be able to meet the performance requirements of today’s traffic, leading to underutilized bandwidth or network constraints.

Security

MPLS provides a secured and managed link between branch offices and the data center through the service provider’s internal backbone. However, SD-WAN can offer better protection by integrating security functions within the network infrastructure itself. By incorporating features like encryption and threat detection into the network fabric, SD-WAN can provide enhanced security compared to MPLS.

While SD-WAN offers numerous advantages, there are cases where MPLS may still be preferred. MPLS can be desirable for certain types of data, applications, and transactions that require a high degree of integrity and privacy. Additionally, in some markets where MPLS is expensive, organizations may opt for a cost-effective public internet connection. However, even in these cases, SD-WAN can still be run over an MPLS connection to provide added protection and functionality.

KEY BENEFITS

Enhanced Agility and Flexibility

SD-WAN provides a centralized control and management platform for your wide area network. SD-WAN solution allows for the dynamic allocation of network resources based on application requirements, traffic conditions, and business needs. This flexibility enables businesses to adapt quickly to changing demands and optimize network performance.

Improved Performance and Application Quality

SD-WAN intelligently routes traffic across multiple network paths, including MPLS, broadband internet, and cellular networks. It leverages real-time analytics and application-aware routing to optimize performance and prioritize critical applications. This ensures consistent quality of service (QoS) for mission-critical applications, resulting in enhanced user experiences and productivity.

Cost Optimization

SD-WAN enables businesses to leverage cost-effective network connectivity options, such as broadband internet, alongside traditional MPLS links. By intelligently routing traffic over the most suitable and cost-efficient paths, organizations can achieve significant cost savings compared to relying solely on expensive MPLS connections. SD-WAN solution also simplifies network management, reducing operational costs associated with provisioning, configuration, and troubleshooting.

Increased Network Security

Inherent security features in SD-WAN service provide enhanced protection for data in transit. Encryption protocols, secure tunnels, and integrated firewall capabilities ensure the confidentiality and integrity of sensitive data. Centralized visibility and control enable efficient security policy enforcement across the entire network, ensuring consistent security posture and reducing the risk of breaches or unauthorized access.

Simplified Network Management

SD-WAN offers a centralized management interface that simplifies network configuration, monitoring, and troubleshooting. IT teams can efficiently provision new sites, apply policies, and monitor network performance from a single platform. This streamlines network operations, reduces complexity, and allows IT personnel to focus on strategic initiatives rather than day-to-day network management tasks.

Scalability and Ease of Deployment

SD-WAN is highly scalable, allowing businesses to easily expand their network infrastructure as needed. New branch offices, remote locations, or cloud connections can be quickly provisioned and integrated into the SD-WAN environment. This scalability and ease of deployment make SD-WAN a suitable solution for businesses with evolving network requirements or those undergoing rapid growth.
