During the mid 2000s, a breakthrough was made, with the application of Software-Defined Networking (SDN) principles, previously the preserve of the datacentre, to the Wide Area Network

The result was Software-Defined Wide Area Networking (SD-WAN) bringing a host of benefits to the WAN, including the ability to run enterprise-standard services over broadband access networks.

This was revolutionary.

WAN infrastructures could be created substantially more rapidly and simply than before. Lengthy, expensive commitments to fixed circuits and MPLS were no longer inevitable. Sites with limited connectivity options could be included in the company WAN. Management and development of the WAN became simpler. Faults could be traced and rectified more quickly. The list goes on.

The catch?

Most off the shelf SD-WAN software originated on the West Coast of the USA. Developed in America, by Americans, it has been designed for the North American market and for North American broadband connectivity: expensive, high quality, highly reliable, low latency, low jitter ADSL.

UK Broadband can be nothing like this, and the bottom line is that SD-WAN software designed for the North American infrastructure won’t work well with conventional UK connectivity. This white paper explores what Evolving Networks has done to address this issue.
