SD-WAN predictions for 2019

Since last three years ago, many people have been talking about SD-WAN technology. And later today it becomes a trend because many enterprises are using SD-WAN in their WAN environments and they gain business value from using it. At the SD-WAN vendor side, they are trying their best to add other requirements besides the current needs of each customer’s WAN edge. Now let’s see how the SD-WAN can deploy in enterprises more than the needed requirements in 2019.
‍‍‍‍‍‍
We would have advanced techniques to distinguish WAN traffic of the enterprises in our SD-WAN. According to the SD-WAN basic technology, we can see which application traffic (E.g. Microsoft, game, etc.) are going to the WAN link by examining the DPI (Deep Packet Inspection).In advance techniques, we will have traffic classifications that decide which application traffic will be put to the white-listed which will pass directly through the Internet and know which traffic will need to pass through firewalls and cloud security services first before moving through the Internet.
‍‍‍‍‍‍
To provide High-Quality Voice and Video Services in enterprises, SD WAN and Unified Communication as a service (UCaaS) are partners to work together. Enterprises now use broadband and thus they are expecting to meet the voice and video quality, availability, and reliability of their UCaaS solutions. Thus, we can drive them in the SD-WAN deployments.
‍‍‍‍‍‍
We can now make deployments to Multi-Cloud using Unified SD-WAN platform. That means our own enterprise data will be on public cloud (e.g., AWS, Azure) or may be on the private data center. We can not only manage the traffic of the data from one location to another but also can keep better security since the data traffic transmits by using the encryption.
‍‍‍‍‍‍
We can use 5G as SD-WAN transportation ,which will be released soon. To have connectivity between WAN links, the newly developed 5G will also count towards as a transport network in SD-WAN like other transport networks such as 4G, Direct Internet Access (DIA) and MPLS. Now then I hope you will know quite a lot about SD-WAN 2019 functionalities. The very last thing I would like to advise is if you use SD-WAN in your enterprise, I hope you will consider our information above to enhance the WAN Edge infrastructure in the future.
