What is SD-WAN (Software-Defined WAN)?

Software-Defined Wide Area Networking (SD-WAN) is a transformative technology that simplifies the IT infrastructure control and management by delivering a virtual WAN architecture that securely connects users to their applications.

The hallmarks of SD-WAN are simplified branch office connectivity, increased reliability, optimized application performance, and increased network agility. SD-WAN lowers total costs, by providing more resource usage and a more automated branch and WAN architecture that is required to fulfill modern IT business initiatives.

SD-WAN aggregates diverse network circuits, like broadband, DIA, and LTE. These circuits can be added to existing MPLS to create a hybrid network, or they can be an alternative to MPLS using all-Internet wired and wireless connections.


How SD-WAN Works

SD-WAN creates an overlay to virtualize the WAN with centralized control to simplify the management and deployment of branch-office services.

Overlay Network

Overlay Network

SD-WAN creates a WAN transport agnostic overlay network and can replace legacy branch office routers simplifying the WAN infrastructure. SD-WAN provides greater control and management, providing application-layer control of application service policies, to ensure optimum application performance.


Application Awareness

Application Awareness

A key element of SD-WAN is application-awareness. SD-WAN understands individual applications and their SLA requirements and translates them into policies that the network must adhere to. This provides active network and application experience monitoring that ensures optimal traffic delivery and QoE – whether on-premises, private/public cloud, or SaaS.

Policy-based Framework

Policy-based Framework

SD-WAN also provides an automated policy-based framework that is propagated from unified control and management, all from a single-pane-of-glass interface. Visibility is enhanced, allowing better IT insights into applications, devices, users, and networking, to ensure adherence to their business goals and objectives. This simplifies ITs ability to define, control, and change business requirements across their branches, data centers, and cloud/SaaS.


Rather than spending time and resources tediously by configuring and managing networks, an effective SD-WAN solution allows enterprises to focus on deploying applications, like IoT, VoIP, unified communications, and edge computing services.

Focusing on improving these business-oriented services, rather than managing WAN complexities, IT can add these (OTT) services to automated and programmable cloud-native platforms. Secure SD-WAN is a cloud-native platform that provides IT with an automated policy-driven, virtual WAN infrastructure. This transforms the network from a bottle-neck impediment to a business service implementation engine.

SD-WAN solutions often offer the following:

Versa Networks enables enterprises to re-architect their enterprise WAN and branch office networks through a software-based and multi-service approach to SD-WAN: leveraging Versa software and low-cost appliances and providing a full set of integrated SD-WAN and SD-Security functions. Organizations can reduce the Capex and Opex of their WAN and branch networks, while increasing IT responsiveness to business needs. The time required to manage the network is minimized, and branch security is strengthened.

Reduce Costs

Reduce Costs and Increase Performance

Versa helps enterprises significantly reduce their WAN connectivity costs by seamlessly integrating Internet, LTE, and broadband alongside MPLS. These options are often higher in bandwidth than MPLS and significantly lower the total cost. Through application-aware routing and the ability to identify thousands of specific applications, Versa Secure SD-WAN carefully map different applications across the network based on your custom business policy and application-specific SLAs.

For example, traffic to Oracle business applications in the enterprise data center can be routed over MPLS, while access to cloud apps like Salesforce and Workday as well as non-business Internet traffic, is better enabled through a secure internet connection. The traffic steering capabilities as well as the security benefits in Versa Secure SD-WAN result in lower overall WAN costs and higher performance.

Increase IT Agility

Increase IT Agility from the Network

Versa Secure SD-WAN enable network teams to remove the barriers that legacy WAN and branch architectures have placed on strategic IT projects and business processes. Versa Secure SD-WAN make the network an agile IT resource through a software-based approach that enables administrators to rapidly provision new branch offices, dynamically add new network and security functions, and seamlessly scale capacity.

If new branch offices are being opened, deploying the branch network with a Versa SD-WAN is as simple as shipping a low-cost appliance, plugging it in, and zero-touch configuring it through central management. Versa Secure SD-WAN makes it easy for you to move quickly with all of your IT requirements.

Branch Networks

Capacity increases can be quickly administered centrally from the Versa Director management platform.

Capex is significantly reduced through replacing expensive, proprietary network hardware with Versa SD-WAN software and low-cost appliances. Opex is greatly reduced as truck rolls for installation and upgrades are eliminated, hands-on time at branch sites is minimized, and system scalability is assured without hardware refreshes.

Deploying SD-WAN

Deploying SD-WAN

Network architectures have always found ways to adapt to changing business dynamics to address modern requirements. Legacy WANs are no longer adequate to meet business needs and most organizations are deploying a hybrid WAN architecture. Hybrid WANs benefited from adopting a software-defined approach, which led to the automation, agility, and increased intelligence from SD-WAN architecture.

Today, SD-WAN has gained greater value through being delivered and managed from the cloud: allowing better speed, scalability, and flexibility. Cloud-delivered SD-WAN is a powerful automated, on-demand, and proactive business approach that enterprises leverage to streamline secure connectivity services that can greatly optimize branch offices and IoT.

SD-WAN devices are better at understanding application traffic flows than legacy WAN. This optimization in application traffic flow allows an administrator to use application and identity-driven policies to make intelligent decisions that adhere to business goals and objectives.

For example: to ensure voice service is always optimal, an administrator can analyze voice traffic to determine how well the user experience is or analyze network circuits to determine how well they are performing. Then, the administrator can correlate those together to make dynamic decisions that optimally traffic steer across the WAN. Application and identity-driven policies can be contextual to who you are, what you are using, and where you are.

Secure SD-WAN for Every Enterprise
