The Power of SD-WAN with MPLS and UCaaS


Demand for SD-WAN continues to grow. Fueled by organizations need for greater bandwidth, increased usage of cloud-based applications and continued trend of remote workforces. End-users needs are changing network traffic patterns and, in turn, require a more efficient connectivity solution that offers a sophisticated foundation for productivity, voice, and data quality.


IT leaders are realizing that the technology doesn’t need to replace MPLS or other connectivity solutions. Instead, SD-WAN complements them and enhances network functionalities, providing transparency and a better end-user experience. When implementing SD-WAN, your 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.


SD-WAN is a perfect match for latency sensitive voice and video applications, such as 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 should be paired with MPLS when:

• You have an existing MPLS network with a diverse and growing portfolio of applications. SD-WAN would allow for traffic segmentation of critical applications to MPLS while offloading less important traffic such as web browsing to best effort cable circuits.
• You do not have auto-failover. SD-WAN architecture is inherently designed to support auto failover because it accepts multiple WAN links, drastically reducing failover time from MPLS to MPLS or public IP.
• You want visibility into the applications running across the network, as well as control of the paths they can/cannot take.
• You have remote branches with limited IT staff. SD-WAN enables IT staff to manage routing functionality and traffic prioritization at all sites from one web portal.
• You have less intelligent IT systems at the branch and do not want to pay for MPLS bandwidth for non-critical traffic.

SD-WAN should be paired with UCaaS when:

• You do not have a solution in place to route traffic and apply priority for voice solutions. SD-WAN routes traffic via business policies to enhance performance, reliability and customer/user experience.
• You are using two different providers for network and voice. SD-WAN encrypts users traffic, further protecting information transmitted.
• You have multiple locations using voice and growing. SD-WAN easily scales, so user can quickly add cloud-based services.
• You are looking for cost-effective, SD-WAN functionalities for its voice solutions. SD-WAN delivers voice and video apps using any cost-effective, readily available transport method (Cable, DSL, etc.)
