What are the benefits of SD-WAN?
Today's corporate infrastructure is supported by the WAN, but in many cases the infrastructure has problems due to heavy traffic. Companies and organizations that utilize MPLS and other networking solutions may encounter service outages, traffic congestion, and packet loss. A typical example of such a problem is the deterioration in the quality of VoIP communications and video streaming that occurs when network demand is high.
SD-WAN addresses these issues seamlessly. Ultimately, the applications and services you use will work as intended, so you don't even need to know if your network uses SD-WAN. The ability of SD-WAN to dynamically route traffic through a hybrid network means that it can reduce WAN traffic overall and increase network agility.
Other benefits of SD-WAN include improved service quality in mission-critical applications, faster routing between multiple network points, and improved visibility of WAN paths. These benefits enable network administrators to more quickly troubleshoot problems and ultimately realize significant cost savings. On the other hand, most SD-WAN solutions use IPSec encryption to protect data wherever it is sent.
Which companies are the top SD-WAN vendors and top providers?With the spread of SD-WAN, the number of suppliers is also increasing. However, not all vendors offer the same level of service. Citrix SD-WAN offers features optimized for businesses and organizations of all sizes. For details, see Integration of Microsoft Azure and Citrix SD-WAN .
Unlike other provider solutions that monitor session-by-session routing, Citrix SD-WAN adapts quickly to any network change by providing packet-by-packet routing. The Citrix solution also detects failures quickly so that application sessions are not impacted. In addition, while other provider solutions do not support asymmetric routing, Citrix solutions show that applications are not symmetric and that symmetric measurements and unidirectional routing are not efficient enough. Once recognized, more optimal efficiency is achieved through asymmetric route selection.
