The WAN is -in computer industry terminology- everything outside the LAN. Where the LAN is the computer network inside a building/organization.
LAN technologies have rapidly evolved in the previous period, having WAN technologies lacking behind. WAN has always been the tradional workspace of the telecomms operators. Since most operators predominantly operated locally WAN technologies have not evolved in pace with LAN technologies.
Internet has changed our way of communicating, making it more interactive. The telecomm operators were forcibly pushed to change their strategies in facilitating bandwidths and still maintaining their -often historically offered- dominant market positions. Telecomm markets were opened by allowing new operators to enter growing competition and reducing prices and tariffs.
But the market grew faster globally than operators could keep in pace with the change rate of the market demands. International customers were faced with too large discrepancies in different countries and regions to adopt a coherent WAN infrastructure. This introduced a dramatic market change where the customer had to take control over their own WAN infrastructure in stead of the ‘old school operators’ dominate the WAN strategy of customers.
In the end it is a logical consequence of processes happening in other areas of the ICT market as well. The enduser will be behind the steering wheel. Market changes will be much more driven bottom-up instead of the traditional top-down.
New initiatives like SD-WAN (Software Defined WAN) have emerged. Manufacturers use different definitions of SD-WAN. Allow us to keep us to our own definition: WAN technology where the end user is in control of the design and implementation in terms of locations, technology used, components, bandwidths and implementation process.
Key components in WAN networks are Routers that separate subnetworks; inside vs. outside office, edge vs. core network, fixed vs mobile networks, primary vs. backup routes, eliminate single point of failures with redundancy etc. etc.
Digital Deal was doing so since 2006, totally unaware of the name SD-WAN. Always Digital Deal had focus on helping its customers to be in control of their own infrastructure (assets). If you buy yourself a car you want to drive it yourself, don’t you?
This leads to WAN products that improve the performance of low-cost WAN links to offer our customers the best of breed performance/cost ratios in WAN technology. The internet is used as a ‘transport’ layer, the customer is kept in control, end-to-end.
