About SD WAN

The software designed WANs (SD-WAN) is an approach to networking with aims at taking software defined networking into two major benefits namely flexibility and cost efficiency. By aggregating several different connections, a network manager can combine them to form one virtual overlay network by the use of traffic engineering to enhance optimization, SD-WANs aims at eliminating the need for expensive MPLS links. With the growth of computing and mobile use, Wide Area Network Optimization (WAN) connectivity is moving to the cloud. The traditional model of WAN optimization is changing towards a consumer paradigm.


By being able to offer faster and reliable internet connection without the need to pay for excess labor, consumers can enjoy virtually flat prices for the speedy internet connections. Having the ability to be connected to the internet with proper speeds I one key benefit of using SD-WAN. Both the service operators as well as the consumers can meet their needs and goals while saving money.

The technology also enables for optimization allowing a multitude of internet components was helping operators to efficiently. The multitude of components allows for regulation as it provides the ability to monitor apps associated with the network. More managed bandwidth connection is established with the incorporation of controlling features through the SD-WAN technology making a “brain: for the telecommunication network system. The reliable internet can be achieved than through conventional WAN. Cloud WAN allows for the storage of information, a user using SD-WAN get access to all the information they need using a small box provided by the service provider.

More functionality is then pushed into the cloud offering the ability to ditch proprietary lock-in. With Cloud WAN integration, getting connected can become as easy as booking a flight. Cloud applications have allowed for making of enterprise technology more comfortable. Virtualization has been achieved enabling anyone to access their information anywhere at any time. Workload having a remote access point is one major advantage. By installing SD-WAN, employees can work from where including home. Getting the job done depends on the work environment and with WAN your place of work is not limited. With WAN innovation, faster, secure movement of data is enabled. Another significant benefit of using SD-Wan is the increase in capability of data handling. The software designed WAN helps cover uses such as streaming or downloading that use up too much bandwidth. It allows for business entities to reach richer data formats while still maintaining its data infrastructure.

SD Wan technology

The key technology behind SD-WAN technologies is the VDN. Virtual Dispersive Network (VDN) is one key technology that allow for routing intelligence handling. Data transmitted through the VDN is forced and split into streams each taking different paths. With the utilization of a single internet connection, transmission of data can be made faster.

Both the Cloud WANs and the SD-Wan are all improvements of the first Wide Area Network (WAN). They both support application process that accesses data center via traffic coming from the cloud and mobile hardware components. Both have been extensions of software defined technology, with improvements in higher performance and speed of connectivity.
