Within SD-WAN, virtualization of network functions that previously existed on dedicated hardware is a key concept. VNFs are these functions that run within the context of a virtualization platform on the SD-WAN hardware. This can range from a container, such as Docker, to a fully-blown virtual machine, such as KVM. Network function virtualization (NFV) is often used along with VNFs and refers the concept of shifting these hardware functions to a virtual platform.

VNFs enable the host platform to report on, control and combine a multitude of dedicated network tasks ranging from VPNs, Firewalls and Anti-Virus to routing, traffic shaping and WAN optimisation. VNFs also play a key part in reducing the effort to provision SD-WAN solutions and features. By presenting their configuration, provisioning and reporting through easy-to-use APIs, VNFs can be quickly applied and removed to satisfy customer needs and network demands.

Replify’s Advantage

For Replify, providing WAN optimization as a VNF is a natural fit. Producing a software based WAN optimization solution was a key goal for Replify when we started in 2006. The inherent flexibility of the Replify software lends itself well to deployment on SD-WAN platforms as a VNF. WAN optimization as a VNF has been identified many times by analysts, vendors and customers as a key feature to consider when choosing an SD-WAN solution. Replify can address this need.

Replify’s OEM licensing model allows SD-WAN vendors to include the Replify technology as a VNF. This adds world-class caching, compression and protocol optimization technology to a customer’s network. This drives up the value of the SD-WAN offering and satisfies one of the key components that end-customers demand when purchasing SD-WAN products.

Replify has worked with a number of top SD-WAN vendors and integrators to ensure the product works seamlessly on a wide range of solutions with minimal effort. By leveraging our software-based heritage, we’ve already been able to deliver value to SD-WAN customers.
