What Are the SD-WAN Faults That Organizations Should Avoid?

By Enterprise Networking Mag | Wednesday, October 30, 2019

In the absence of a comprehensive SD-WAN deployment plan, companies will end up with applications that do not work well or with the ones that might not work at all.

FREMONT, CA: SD-WAN is a virtual WAN structural design that allows enterprises to depend on any combination of transport services such as MPLS, LTE, and broadband Internet to link users to applications safely. The technology is wide-spread now and is being used to connect dispersed branch offices as well as to enterprise networks. It helps them in triggering the application performance, enhancing business productivity, and narrowing down the IT expenses.

But many SD-WAN benefits are missed because of a handful of common deployment faults. Here are some general pitfalls, which can be avoided easily.

Adopting an Inappropriate Approach:

Even though SD-WANs are robust, flexible, and adaptable, they can still be challenging when it comes to design and installation. While planning SD-WAN, companies need to think about the end-to-end solution rather than focusing on individual technical elements. 

Picking them should not be according to their technical abilities only, but also every available approach and then choose the one that meets the needs and budget of the organization. It is ideal to look for a full-service approach to the network, involving the SD-WAN abilities with the highest level of automation and intelligence present within the platform. 

Failing Assurance:

High Quality of Service (QoS) and Quality of Experience (QoE) are crucial attributes for SD-WAN that require supporting voice and video. It is significant, therefore, to hunt for the SD-WAN approach that delivers a no-fail technology and also the one that is offering efficient-than-MPLS performance for real-time applications.

SD-WAN planners must search for a technology that delivers constant unidirectional measurement of traffics between any pair of locations. The technology aggregates bandwidth from different links as well as supports optional packet duplication for delivering VoIP and videoconferencing call quality.

Thoroughly Addressing SD-WAN Security Requirements:

The network functions that exist already are sometimes overlooked during experimentation. Numerous SD-WAN technologies require stronger security abilities natively but display themselves differently as if they can replace the existing security functionality. Organizations are welcoming the threats if the SD-WAN solution is in short of security capabilities.

Security lapses can be eliminated by planning, and some SD-WAN solutions enable the organizations to incorporate the security features into SD-WAN functions to enhance protection.
