Learn More about SD-WAN
SD-WAN which is short for software-defined networking in a wide area of network, is one of the new products of the two most important technologies namely the internet and the computer, and its main function is to simplify the management and operation of a wide area network by separating or decoupling the network hardware from its mechanism of control. One of the consumer target of the inventors of SD-WAN are business or commercial companies, and this certain technology is allowing their consumers and users to build higher performance of wide area network by enabling these businesses to either partially or wholly replace their expensive private WAN connection technologies like MPLS or multiprotocol label switching, and that is by using lower cost leased lines. The benefits that a business company can obtain from using such great technology are the privilege of extending their computer networks over a larger distance, to deliver the applications and services required to perform business functions and to connect remote branch offices to data centers and vice versa. The SD-WAN products is basically designed by the inventors to address problems in the network and any other operation challenges such as service outage, network congestion, lower latency requirements of modern operations like video conferencing, streaming media, virtualized applications and desktops, and VoIP calling, bandwidth requirements for featuring high-definition video, difficulty and expensive costs of expanding WAN capability, difficulties in management of network and troubleshooting jitter and packet loss. In using the SD-WAN it enhances and replacing the traditional branch routers by using virtual appliances, and these appliances can control the application-level policies and offer an overlay of the networks with the use of a less-expensive consumer level internet links which acts as a dedicated circuit.

An SD-WAN product can be a physical appliance or a virtual appliance and they are commonly placed in small remote offices, branch offices, corporate data centers and cloud platforms. The required characteristics of every SD-WAN products includes the ability of doing dynamic path selection which can be used for resiliency purposes or load sharing, the ability of supporting multiple connection types like frame relay,
MPLS or multiprotocol label switching and higher speed LTE or long-term evolution wireless connections, the ability to support VPNs or virtual private network and third party services like WAN optimization controllers, web gateways and firewalls and a simple interface that is very easy to manage and configure. The SD-WAN products offers great features to their consumers and users and that includes QoS or quality of service, security, resilience, flexible deployment options, and troubleshooting and simplified administration.
