The Benefits a Company can Obtain from Using SD-WAN
The SD-WAN or software-defined networking in a wide area of network, is basically a product produced by the use of the two most important technologies of all time, such as the internet and computer, and its primary function is to simplify the operation and management of a wide area network by decoupling or separating the network hardware from its control mechanism. 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 business companies who are using such great technology can obtain the various benefits brought to them by such products and that includes the chances and privilege of connecting to remote branch offices to data centers and vice versa, delivering the applications and services that are required to perform the functions of these businesses and lastly, is the privilege of extending over a larger distance the computer networks that they have within their company. The products that are called as SD-WAN are designed by its manufacturers to address operational challenges or any other network problems that are existing, and some of the examples for these includes packet loss, 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 and jitter. When using the SD-WAN product it can now functions by replacing and enhancing the branch routers that are traditional by using virtual appliances, which main uses is to offer an overlay of the networks through the use of an inexpensive consumer level internet links which is designed to act as a dedicated circuit and controlling the application-level policies.
The software-defined networking in a wide area of network or SD-WAN product can be a virtual appliance or physical appliance and commonly, they are being placed by the users and consumers in cloud platforms, corporate data centers, small remote offices and branch offices. The characteristics of an SD-WAN products which is a requirement for the inventors and manufacturers includes 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, a simple interface that is very easy to manage, and configure the ability of doing dynamic path selection which can be used for load sharing and resiliency purposes. The great common features that are being offered by the manufacturers to their probable clients and consumers includes flexible deployment options, and troubleshooting, simplified administration, includes QoS or quality of service, resilience, and security.
