2. How Does SD-WAN As A Service Work?

SD-WAN as a Service combines the benefits of SD-WAN technology with the convenience and expertise of a managed service model. Let’s take a closer look at how it works:

The Technology Behind SD-WAN As A Service

At its core, SD-WAN as a Service utilizes software-defined networking to centralize managing and controlling an organization’s wide area network.

The service provider deploys a software-based SD-WAN controller that interacts with edge devices located at the customer’s premises, such as routers and SD-WAN appliances.

This centralized controller allows the service provider to define and enforce network policies, monitor network performance, and make real-time routing decisions based on application requirements, network conditions, and business priorities.

These routing decisions are communicated to the edge devices, which forward the network traffic accordingly.

Features and Capabilities Of SD-WAN As A Service

SD-WAN as a Service offers a wide range of features and capabilities that optimize network performance and simplify network management:

1. Application-Based Traffic Routing: SD-WAN as a Service can intelligently route network traffic based on the specific requirements of each application. Businesses can ensure optimal performance by prioritizing critical applications and dynamically adjusting the network path, even for bandwidth-intensive applications.
2. Dynamic Path Selection: SD-WAN as a Service continuously monitors the performance of available network paths and selects the most efficient path for each application at any given time. This proactive approach minimizes latency, packet loss, and jitter, ensuring a seamless and consistent user experience.
3. Quality of Service (QoS) Controls: SD-WAN as a Service allows businesses to assign different levels of priority and bandwidth allocation to specific applications or traffic types. This fine-grained QoS control ensures that critical applications receive the necessary resources while preventing non-essential traffic from degrading network performance.
4. Security and Compliance: SD-WAN as a Service integrates robust security features to protect the network and data. Service providers can implement firewall capabilities, encryption, intrusion detection and prevention systems, and content filtering to safeguard against cyber threats.
5. Centralized Management and Monitoring: SD-WAN as a Service provides a centralized management interface that allows businesses to monitor network performance, configure network policies, and generate performance reports. This unified management approach simplifies network operations and enhances visibility across the entire WAN infrastructure.

How SD-WAN As A Service Streamlines Network Management

One of the main advantages of SD-WAN as a Service is its ability to simplify network management.

With traditional WAN solutions, businesses face the challenge of managing multiple vendors, complex hardware configurations, and disparate network protocols.

SD-WAN as a Service overcomes these challenges by providing a unified and centralized management platform.

The service provider takes care of the hardware procurement, device configuration, and ongoing maintenance, ensuring that the network operates smoothly and efficiently.

Businesses can access the management platform to monitor network performance, configure policies, and troubleshoot issues without requiring specialized IT expertise or extensive training.

This streamlined approach to network management allows businesses to allocate their IT resources strategically.

IT teams can focus on strategic initiatives and core competencies rather than spending valuable time and resources on network troubleshooting and maintenance tasks.
