Everything You Must Know About SD-WAN

Software Defined networking in Wide Area Network is otherwise called as SD-WAN. SD-WAN is being used for simplifying the management and operation of WAN by way of decoupling or separating networking hardware right from the control mechanism. This idea is almost similar to the way how software defined networking is implementing virtualization technology in order to improve operation as well as data center management.

The key application for SD-WAN is to allow companies develop higher performance wide area networks by utilizing commercially available as well as low cost internet access. Through this, it allows the business to replace their private WAN connection technology either partially or in whole.

WANs are allowing companies to further extend their networks over broader distances, to connect to their remote branches to both data centers and each other and also, to deliver applications and services needed to carry out business functions effectively. As a matter of fact, there are countless of operational challenges that companies face when trying to extend their network across multiple networks of carriers and when trying to cover longer distances. This includes but not limited to network congestion, packet loss, jitter and occasional service outages.

Be it VOIP calling, streaming media, video conferencing and virtualized desktops etc. all these new innovations call for low latency. The bandwidth requirements are increasing too especially for apps that feature HD vides. It may be expensive and hard at the same time in expanding the WANs capability. SD-WAN products are made mainly for addressing these network problems. By way of replacing or enhancing traditional branch routers using virtualization appliances that control application level policies as well as offering network overlay, the less costly consumer grade internet connections may function more like a dedicated circuit.

This simplifies the setup process for branch personnel whether you believe it or not. You can have your SD-WAN products available in virtual or physical appliances and you can install it as well on small businesses, corporate data centers, bigger offices, remote offices and even on cloud platforms.

The centralized controller is used to prioritize the traffic and set policy. SD-WAN also take into account these said policies and availability of the network bandwidth in terms of routing traffic. Basically, this helps in guaranteeing that the performance of application always meets the SLA or Service Level Agreements.

According to research, it is defined that an effective and efficient SD-WAN always carry 4 major characteristics and these are the ability of supporting multiple connections, the ability of doing dynamic path selection for resiliency and load sharing purposes, ability of supporting VPNs and other third party services and provide a simple interface that’s both manageable and configurable.
