That said, the two have significant differences in how they accomplish these goals.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-sd-wan-overview-nbsp\">SD-WAN Overview\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.catonetworks.com\/sd-wan\/\" target=\"_blank\" rel=\"noreferrer noopener\">SD-WAN<\/a> is a logical overlay network that connects corporate locations. SD-WAN ensures WAN&#8217;s reliability and performance by monitoring network links&#8217; health and selecting the best available route.\u00a0 SD-WAN appliances are often connected to multiple network links to ensure resiliency in the face of a potential outage or service degradation of a provider\u2019s network.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-mpls-overview-nbsp\">MPLS Overview\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.catonetworks.com\/what-is-mpls\/\" target=\"_blank\" rel=\"noreferrer noopener\">MPLS<\/a> uses dedicated links between corporate locations and routes traffic more efficiently than traditional IP-based routing, avoiding public internet connectivity and providing reliability and performance guarantees for corporate WAN service. MPLS service level agreements (SLAs) ensure a certain level of performance and uptime.\u00a0<\/p>\n<p><\/br><\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-advantages-of-mpls-over-sd-wan-nbsp\"><span class=\"ez-toc-section\" id=\"Advantages_of_MPLS_over_SD-WAN\"><\/span>Advantages of MPLS over SD-WAN\u00a0<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">MPLS is a more established technology and provides the following benefits:\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-reliability-nbsp\">Reliability\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">Dedicated links between corporate locations ensure reliability by avoiding public internet. This directly contrasts SD-WAN, which uses public Internet to carry WAN traffic where reliability is determined based on the underlying public Internet infrastructure.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-quality-of-service-nbsp\">Quality of Service\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">MPLS defines classes of service that prioritize certain traffic types and take full advantage of performance guarantees while deprioritizing less important traffic dependent on low-latency connectivity.\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">SD-WAN also implements quality of service (QoS) policies and prioritizes certain traffic types. However, even with QoS, SD-WAN is dependent on the public internet and provides lower performance guarantees than MPLS.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-security-nbsp\">Security\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">A major advantage of MPLS is the security gained through dedicated WAN links between corporate locations. On the other hand, SD-WAN creates a virtual overlay on top of existing networks. Access controls and security protections are implemented at the software level, exposing WAN traffic to software vulnerabilities and other potential cyber threats.\u00a0<\/p>\n<p><\/br><\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-advantages-of-sd-wan-over-mpls-nbsp\"><span class=\"ez-toc-section\" id=\"Advantages_of_SD-WAN_Over_MPLS\"><\/span>Advantages of SD-WAN Over MPLS\u00a0<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<h3 class=\"wp-block-heading\" id=\"h-cost-effectiveness-nbsp\">Cost Effectiveness\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">As a virtual overlay on top of existing network infrastructures, SD-WAN is much more cost-effective than having dedicated links.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-application-visibility-amp-control-nbsp\">Application Visibility &amp; Control\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">As a self-managed or co-managed solution, SD-WAN provides visibility and control of applications flowing over the network. MPLS, being fully managed by the telco, does not provide self-management or co-management options, which are not provided to the organization.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-availability-nbsp\">Availability\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">SD-WAN performs continuous link health checks and route optimization, allowing it to adapt to a variety of network conditions and avoid network outages. MPLS, on the other hand, is tethered to dedicated links. So, an outage will adversely impact the corporate WAN service.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-flexibility-and-scalability-nbsp\">Flexibility and Scalability\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">As a virtual overlay network, SD-WAN is more flexible and adaptable to change as network and business requirements evolve. MPLS is very rigid and requires a service ticket with the telco for network changes or capacity growth requirements.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-simplified-management-nbsp\">Simplified Management\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">Most SD-WAN deployments are cloud-managed and provide a centralized view of the network, making it easier to manage than MPLS.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-granular-control-nbsp\">Granular Control\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">Granular visibility of the network is a key benefit of SD-WAN, and this enables organizations to define application-specific rules and policies for a higher level of control. MPLS, while providing QoS capabilities, lacks the same granularity of control of SD-WAN.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-cloud-support-nbsp\">Cloud Support\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">SD-WAN makes it easy to provide connectivity between branch locations and cloud data centers while maintaining visibility and control over the corporate WAN. MPLS was not designed to deliver cloud services, which forces organizations to backhaul traffic through the corporate data center before routing to cloud-based applications. As a result, this traffic experiences increased <a href=\"https:\/\/www.catonetworks.com\/glossary\/what-is-latency\/\">latency<\/a>, which negatively impacts application performance and user experience.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-advanced-security-nbsp\">Advanced Security\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">Both SD-WAN and MPLS provide a certain level of security for WAN traffic. However, neither solution offers the native security capability to inspect network traffic for advanced threats. As a result, organizations must deploy a separate network security solution to ensure that all traffic is protected.\u00a0<\/p>\n<p><\/br><\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-the-case-for-either-mpls-or-sd-wan-nbsp\"><span class=\"ez-toc-section\" id=\"The_Case_for_Either_MPLS_or_SD-WAN\"><\/span>The Case for Either MPLS or SD-WAN\u00a0<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">MPLS and SD-WAN are both effective corporate WAN solutions, and neither is inherently superior to the other. The right decision on technology depends on an organization\u2019s unique business needs.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-when-to-choose-mpls-nbsp\">When to Choose MPLS\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">The primary advantage of MPLS over SD-WAN is the performance and reliability guarantees that are backed by SLAs. SLA guarantees make MPLS a better choice for latency-sensitive, mission-critical applications.\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">Another argument for MPLS over SD-WAN is compliance and security. The dedicated connectivity of MPLS provides better security than SD-WAN.\u00a0<\/p>\n\n<h3 class=\"wp-block-heading\" id=\"h-when-to-choose-sd-wan-nbsp\">When to Choose SD-WAN\u00a0<\/h3>\n\n<p class=\"wp-block-paragraph\">SD-WAN offers improved cost-effectiveness, flexibility, scalability and availability. Depending on the underlying physical infrastructure, SD-WAN can also provide improved performance and reliability when compared to MPLS; however, these are not necessarily backed by SLAs as with MPLS.\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">SD-WAN is likely a superior alternative to MPLS for any use case that doesn\u2019t require an SLA-backed guarantee. For example, an organization may use SD-WAN for non-business-critical applications and integrate with MPLS for business-critical or latency-sensitive applications. Policies can then be used to ensure that MPLS connectivity is available to those applications.\u00a0<\/p>\n<p><\/br><\/p>\n\n<h2 class=\"wp-block-heading\" id=\"h-mpls-to-sd-wan-migration-nbsp\"><span class=\"ez-toc-section\" id=\"MPLS_to_SD-WAN_Migration\"><\/span>MPLS to SD-WAN Migration\u00a0<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">For most companies, making the move to SD-WAN is a logical choice. It offers comparable performance and reliability to MPLS in most cases. While SD-WAN is only as reliable as the public internet, it is still a more flexible alternative for organizations in dynamic growth mode or pursuing digital transformation initiatives.\u00a0<\/p>\n\n<p class=\"wp-block-paragraph\">Cato offers the SLA-backed guarantees of MPLS combined with the dynamic flexibility of SD-WAN. Cato SD-WAN runs on top of a network of dedicated, Tier-1 carrier links, ensuring better performance than SD-WAN over the internet.
