SD-WAN + UCaaS
SD-WAN is a perfect match for latency-sensitive voice and video applications, such as Unified Communications as a Service (UCaaS). SD-WAN can improve voice quality, reducing issues around packet loss, jitter, etc. that make for a poor user experience. For example, a voice application can run on one internet connection and be failed over to another in the event there’s an issue, maintaining the voice session, without the user being impacted.
SD-WAN + MPLS
While iQuoteUC can certainly help you determine your ideal network needs, IT leaders are realizing that SD-WAN doesn't need to replace MPLS or other connectivity solutions. Instead, SD-WAN can complement and enhance network functionalities, providing transparency and a better end-user experience. When implementing SD-WAN, customers' existing network does not go away, but instead becomes the underlay technology. MPLS, for example, is still needed for guaranteed QoS end to end, particularly for verticals that require secure and compliant transmissions of data.
