SD-WAN, the best ally for your Wide Area Networks
Even today in the midst of the great boom that virtualization is experiencing, many companies that extend their networks to greater distances, hesitate when it comes to integrating SD-WAN in their corporate environments. The benefits of simplification in administration are undeniable, but there is still some fear regarding the costs of this technology.
For those who don’t have it very clear yet, SD-WAN is a style to design Wide Area Networks (WAN) by using Software-defined networks (SDN) in order to route traffic to remote locations. In a few words, this is a more effective way to automate many management tasks with the use of software. Undoubtedly, it is extremely vital to operate networks as complex as the WAN.
WAN or SD-WAN optimization?
There is a belief that SD-WAN and WAN Optimization are similar concepts. They indeed have some points in common, especially the issue of the network functions virtualization, but they are not the same thing. WAN Optimization is a group of techniques to improve the efficiency of data transfer among branches and data centers over WAN networks.
However, SD-WAN, besides accelerating the application delivery, allows for the increase or reduction of bandwidth with the use of virtualization techniques in order to control the traffic WAN optimization offers. On the other hand, software-defined WAN technology allows you to incorporate advanced features, such as traffic routing based on applications or customized security provisions to meet stringent market demands.
Corporate Challenges Solved by SD-WAN
Modern business networks become increasingly complex and when it comes to organizations that need to expand their networks, the operational challenges are even greater in terms of important aspects as network congestion, jitter, packet loss, service outages, and latency reduction; which are so necessary to support modern applications, such as VoIP services, video conferencing, on-demand streaming and virtualized applications.
With SD-WAN the magic to manage and solve these complexities appears. This technology uses virtualization devices to control application-level policies and provide network overlap. Security, back-end binding, engineering, traffic visibility, and quality of service (QoS) are all aspects that SD-WAN manage effectively.
Cost Reduction: Software-defined WAN networks give organizations the ability to design their wide area networks to achieve higher performance by means of the use of low-cost Internet access. This eliminates a great deal of private WAN connection technologies that are much more expensive, like MPLS.
Network Inactivity Reduction: Detecting interruptions in real time is extremely important. SD-WAN guarantee that, because it also offers bandwidth priority for the most critical applications and improves the information storage to accelerate future access.
Advantages for administrators…
SD-WAN is a relief in many ways for administrators. It is very comfortable to manage through a single interface any anomaly that appears in a data center. This would avoid manual configuration of traditional routers in the different branches of the company.
Online Traffic Engineering: Having a global and real-time view of the networking issues is something that SD-WAN can easily do. Software-defined WAN networks perform a central calculation of transmission speeds in the controller and limit the speed in senders according to speeds.
