MPLS vs SD-WAN Enterprise Comparison: Cost and Performance

Looking to modernize your enterprise WAN? Explore how SD-WAN can help you reduce costs, improve performance, and build a more flexible network with Equinix: https://eqix.it/3Uqgruh This MPLS vs SD-WAN enterprise comparison covers cost and performance side by side: what a classic MPLS WAN is (provider P routers, provider edge PE, customer edge CE, private connectivity across remote sites and data centers), why teams added cheaper internet paths and needed an overlay, and how SD-WAN filled that gap. The stronger SD-WAN architecture design for the enterprise does not stop at internet tunnels. It starts at an Equinix IBX, replaces the MPLS core with Equinix Fabric (high-speed, ultra-low latency network-as-a-service between IBXs), uses carrier Ethernet and internet for last-mile options, and deploys SD-WAN as physical appliances or virtual network functions on Equinix Network Edge—hybrid WAN architecture the enterprise can operate. SD-WAN vs MPLS cost and performance in practice: private multi-point Fabric paths with shortest-path routing, API-controlled bandwidth, and cloud on-ramps—AWS Direct Connect, Azure ExpressRoute, and Google Partner Interconnect—at the same interconnection hubs. When to replace MPLS with SD-WAN is less about ripping every circuit on day one and more about redesigning the WAN: keep the sites, change the core and the overlay, and follow an MPLS to SD-WAN migration pattern built on SD-WAN fundamentals—private interconnection backbone plus hybrid last mile, not only an internet-first mesh. SD-WAN deployment best practices in this design: anchor at IBX, Fabric between hubs, carrier Ethernet and/or internet to the edge, SD-WAN on Network Edge, then attach cloud on-ramps where you already interconnect. FAQs: Q: What is MPLS networking in an enterprise WAN? A: An MPLS network connects remote locations over private provider connectivity. At the core are provider (P) routers, surrounded by provider edge (PE) devices, with customer edge (CE) routers on the facility last mile—sites, data centers, and other locations on the same MPLS WAN. Q: What is SD-WAN and how does SD-WAN work? A: SD-WAN (software-defined WAN) is the overlay that lets you tunnel and steer traffic across MPLS, internet, or both under software control. It emerged because internet bandwidth was cheaper than MPLS alone, but raw internet lacked a clean overlay between sites—OEM SD-WAN filled that gap. In short: SD-WAN explained simply is software control of the WAN path, not a single access type. Q: How does SD-WAN vs MPLS compare on cost and performance? A: Legacy MPLS-only designs often miss lower-cost paths and flexible bandwidth. An IBX-centered design uses Fabric between hubs for private, low-latency multi-point connectivity, carrier Ethernet for MPLS-like performance at lower cost on many last miles, and internet as an alternate path with SD-WAN steering across them. Q: What does SD-WAN architecture design for the enterprise look like? A: Start at Equinix IBX locations, interconnect IBXs with Equinix Fabric (replacing the MPLS middle), connect remote sites with carrier Ethernet and/or internet, deploy SD-WAN physical or virtual on Network Edge, then attach cloud on-ramps (Direct Connect, ExpressRoute, Partner Interconnect) where you interconnect. That is hybrid WAN architecture for the enterprise with cloud adjacency built in. Q: How fast can you provision this style of WAN? A: Speed is often measured in days versus weeks or months for traditional builds. One customer example: a global WAN brought up in under an hour during an outage—illustrative of automation and pre-built interconnection, not a guarantee for every estate.
