Why You Should Adopt SD-WAN For Your Company

In 2019, it was made clear that SD-WAN is now being seen as the future of enterprise Wide Area Network (WAN) connectivity. With the rapid adoption of cloud services and applications, a significant amount of business traffic is moving over public internet instead of staying in the company’s Wide Area Network as it used to be. SD-WAN becomes the hub of many internet and WAN circuits simultaneously to dynamically direct traffic across the best, less congested pathway. By checking the quality connections and the speed at which a specific type of traffic will reach its destination when traveling over a pathway, it determines the optimal pathway.

SD-WAN works by separating applications from the underlying network services with a policy-based, virtual overlay. The overlay monitors real-time performance characteristics of the underlying networks, it then selects the optimum network for each application based on configuration policies. By monitoring the performance of the networks, SD-WAN can direct traffic over the most efficient route available, it might be the company's MPLS line or a 4G LTE connection. If any of these connections are lost SD-WAN will automatically reroute traffic over any alternative circuits so that session-based applications such as VoIP calls are not interrupted.

SD-WAN offers dozens or hundreds of ways to map application prioritization compared to a handful of options for tagging and mapping MPLS traffic. SD-WAN is capable of identifying hundreds to thousands of applications and can map these applications into queues.


Devices such as tablets, smart phones, and computers are connected to networks in your personal space like your office or home by LANs (Local Area Networks). These various personal spaces situated in different geographical locations around the globe remain connected with WANs. As it works in companies, WANs grow on SDNs while facilitating the interconnection of every company in different locations in order for each branch to stay linked together and ease the flow of data traffic.

Though a connection among branches of a company can be achieved by using the traditional broadband internet connectivity, the company's data flow will fully rely on internet used by the general public. A company’s data flow may contain sensitive information about a company. This is the reason VoIP services like Ooma constantly ensure that an exclusive connection is made to their network in order extricate the unfavorable impact associated with internet traffic and its effect on QoS and the quality of voice. Due to the need arising for a private connection, WANs that are capable of providing better traffic priority like those provided by MPLS connections, which is now being provided by SD-WAN vendors and companies.

SD-WAN provides streamlined network management, no software or hardware components need to be deployed from each remote site, every networking tool is consolidated into a policy-driven, centralized management interface. SD-WAN can increase your network performance and agility. In modern-day business connectivity is key. Since SD-WAN can automatically route traffic through the fastest connection, network issues like jittery and latency are reduced.
