Optimize your network with SD-WAN.

Offering a more flexible solution than MPLS and designed for modern enterprise network requirements deep-seated in cloud computing and the use of mobile devices, SD-WAN is more reliable, scalable and better equipped to support a globally dispersed workforce than VPN-based WAN.

A more cost-effective and operationally agile solution than MPLS, SD-WAN streamlines WAN management and scalability while reducing overall CAPEX and OPEX.

MPLS migration to SD-WAN

In partnership with CATO Networks, UniVoIP customers are now able to shift from inflexible MPLS networks that are not only expensive, but also capacity-constrained, to a combination of high-capacity Internet links and the UniVoIP cloud. Boosting usable capacity and improved resiliency at a lower cost per megabit, UniVoIP Socket edge SD-WAN appliances are the perfect solution for customers with a global footprint looking to replace the unpredictable internet. With the UniVoIP cloud, on-premises and cloud applications performance are maximized and optimized to their fullest potential.

What You Gain with SD-WAN technology

As a virtualized WAN architecture, SD-WANs allow enterprises to use numerous different transport mechanisms, including LTE, MPLS, and broadband Internet connections. Ultimately, SD-WANs can leverage all of those different connectivity methodologies to connect users to applications.

SD-WANs also introduce centralized management and orchestration, reducing much of the burden associated with managing and provisioning a WAN. That centralized orchestration allows network managers to define policies that can leverage the full power of the connectivity services used. Take for example link-load balancing. Here the SD-WAN policy can be defined to combine multiple internet connections in active/active to act as a larger transport pipe, increasing throughput.

The ability to load balance traffic across multiple pipes brings additional advantages, such as automatically incorporating redundancy into the WAN topology and supporting the concept of automatic failover. Simply put, if any one link fails, traffic will be routed over another link to maintain connectivity.

How Does an SD-WAN Really Work?

SD-WANs are formed by establishing encrypted tunnels (the “overlay”) between sites. Every site is equipped with an SD-WAN device. Once connected to the local networks, those devices automatically download custom-defined configuration and traffic policies and establish tunnels with one another or a point of presence (PoP), depending on the architecture.

Routing and traffic control is managed by the SD-WAN. Outbound traffic is routed along the optimum path based on application policies and real-time traffic conditions. Should one last mile connection fail, the SD-WAN device automatically fails over to the alternative connection, using pre-configured policies to manage the traffic load.

As such, policy-based management is obviously a key component of an SD-WAN. Policy is used to determine dynamic path selection and will steer traffic based upon the level of priority, such as quality of service (QoS) it is given. Numerous policies can be created to meet specific business needs, such as granting packet transmission priority for VoIP and other interactive services to improve performance.
