SD-WAN is an acronym for software-defined networking in a wide area network (WAN). A key application of an SD-WAN is allowing companies to build higher performance WANs using lower cost Internet access, enabling businesses to partially or wholly replace more expensive private WAN connection technologies such as MPLS. Nowadays there are two major approaches selected to establish SD-WAN.

drawing Some companies choose the device-driven SD-WAN solution. This approach requires SD-WAN devices to be installed at both the company branch and headend locations, usually builds an overlay across multiple carrier networks. Thus customers are able to use the SD-WAN centralized management capabilities to have business level policy control to steer the application flows per requirements.

Alternatively, SPs build SD-WAN overlay to the edge of their network (at the NNI or Internet POPs). The SD-WAN overlay tunnels are terminated at the SD-WAN headend sitting at the edge of the SP's network and original traffic is handed off to SP's MPLS backbone. End user SD-WAN sites get instant access to other sites and SP resources on MPLS.

Both scenarios have their limitations. For the former, Internet is yet far from ideal to provide managed networking service. For the latter, there is not much change in SP's MPLS network backbone, SD-WAN acts just as a supplement to traditional MPLS deployment. Differently, Freecomm's SD-WAN service is built on top of farfree, an intelligent global network infrastructure with integrated security, without historical burden of MPLS and leaving device option to customers.

Intelligent Network

SDN evolution happens not only at the edge of network or device, but also within the network core. Freecomm SD-WAN service provides brand-new network experience by utilizing intelligent SDN backbone of farfree. With real time detection of outages and automatic switches, the network can always provide the fastest route from node to node.

Built-in Security

With the built-in security of farfree, packets are encrypted with the use of dynamically rotating security keys whenever leaving or moving between Freecomm's POPs. This process creates a fully secured network fabric that operates independently of the underlying transports.

Clear User Interface

For those who are using Internet to access Freecomm SD-WAN service, the user interface is clear and simple. Users are responsible for local Internet connection, Freecomm takes care of the rests.

Global Coverage

Customer can get a cross connect to our POPs or use overlay tunnels via Internet. In addition to direct access, Freecomm is open for NNI connection with other SPs through our POPs worldwide. Global network coverage is not just an issue about resources, capital and technology, but also leads to be consistent with national policies and market admittance. By running farfree, which is based on and in harmony with Internet, Freecomm archives global service delivery while respects and complies with national regulations.
