SD-WAN vs. Traditional WAN

Make the branch office agile and efficient with virtualization and cloud.

Compared to a traditional WAN deployment, SD-WAN enables enterprises to deploy their wide area networks 100 times faster with 3 times the cost-savings.

Traditional WAN Is Broken

Traditional WAN design is based on multiple devices stacked in the branch office with siloed management and disparate WAN links connecting them.

Expensive Bandwidth

Limited bandwidth of expensive private/MPLS circuits inhibits rollout and impacts performance of applications. At the same time, private/MPLS WAN redundancy is complex to deploy and manage.

Unpredictable Application Performance

Application traffic over Internet links lacks SLAs for predictable performance. Every change in the application quality of service requires manual changes across the branches and the datacenter.

Datacenter Dependent

With no direct access to cloud resources from the branch with the archaic hub and spoke network design, the traffic is backhauled through the enterprise datacenter with heavy performance penalties.

Complex Infrastructure

Traditional WAN includes multitude of single-function devices and appliances connecting via different WAN links. This infrastructure sprawl causes complexity of branch IT management.

SD-WAN Makes Branch Networks Better

Software centric approach capable of being delivered prepackaged on economical x86 platforms or virtually on existing router and server platforms.

Virtual WAN

 Deliver a network overlay with multiple links from different service providers to form a unified pool of bandwidth. Provide superior performance and high availability for applications independent of the underlying transport links.

Simplified Branch Services

SD-WAN provides insertion of network services whether on the branch customer premise equipment (CPE), in the cloud, or in regional and enterprise data centers. Software-defined flexibility with automation and business-policy abstraction simplifies complex configurations of traffic routing and policy definitions.

Cloud-Optimized

Enterprise-grade performance is assured even when traffic is going to the Cloud applications. Incremental overlay design abstracts software layer from the underlying hardware layer and the physical transport to make an elastic network.

Pay-As-You-Grow Model

SD-WAN gives enterprises the ability to deploy a wide area network on-premise or cloud and ease the services insertion with application-aware forwarding to enterprise datacenter or cloud. The cloud-based management enables pay-as-you-grow subscription model for cost efficiency.
