The best MPLS alternatives for multi-site networks

Key takeaways

• MPLS is shrinking fast: WAN managers ran MPLS at an average 22% of their sites by late 2025, down from 82% in 2018.
• One answer rarely fits every route: Layer 2 Ethernet, dark fiber, wavelengths, and SD-WAN over internet each suit a different kind of traffic between sites.
• Match the alternative to the route: Traffic volume, privacy needs, cloud reach, and local carrier options decide what each site pair should run on.
• Plan for a period of overlap: Most teams keep some MPLS while they move, so contract end dates and site groups should set the order.
• Countries change the answer: Internet quality and regulation vary by market, so a multi-country network may run different options in different regions.

Let it roll over, and the same circuits, prices, and single-carrier dependence stay in place for another term. TeleGeography's WAN Manager Survey found that MPLS fell from an average of 82% of sites in 2018 to 22% by late 2025.

MPLS is a private WAN service where the carrier routes traffic between your sites across its own network. SD-WAN fits branch offices well, and MPLS alternatives for a multi-site network also have to carry data center replication, private links between headquarters and plants, and traffic to several clouds. Those routes need capacity and privacy that an internet overlay doesn't always provide.

A clean move off MPLS takes several decisions. Sort routes by what each one carries, pick the alternative that fits each route, and move one group of sites at a time while the old circuits still run.

Why companies replace MPLS

MPLS IP VPNs took hold when most traffic ran between branches and a central data center. In the IETF's MPLS architecture, each router reads a short label to choose the next hop and swaps it for a new one. In an MPLS IP VPN, the provider runs the routing, prioritizes traffic by class, and keeps it on a private network.

Three pressures pushed teams to look for an MPLS replacement.

• Cost per megabit: MPLS costs 50% to 500% more than gigabit dedicated internet access in all 10 key markets, TeleGeography priced in Q1 2026.
• Traffic in the cloud: Apps now live across several public and private clouds, and TeleGeography's latest WAN Manager Survey, published in March 2026 with 52 responses, found that connecting offices to multiple cloud providers has significantly increased network complexity.
• Single-carrier dependence: Companies that buy MPLS from one global provider rely on its footprint and local partners at every site, and the State of the Network 2025 report found that 27% of companies sourced their MPLS that way.

The money is following the shift. TeleGeography forecasts that MPLS revenue will fall from $130 billion to $57 billion between 2025 and 2030, while dedicated internet access and SD-WAN grow.

MPLS covered an average of 22% of sites in late 2025, down from 82% in 2018, according to TeleGeography, and the move takes years. That survey found that 74% of respondents still use MPLS at some sites, mainly because of long transition times, quality of service requirements, and private network security needs. Any replacement has to meet the same quality of service and privacy needs.

What an MPLS replacement has to cover across sites and countries

An MPLS replacement has to match what MPLS did well at every site it served, in four areas.

Private paths where the data demands it

Some traffic has to stay off the public internet by policy or contract, such as regulated data, plant control systems, and storage replication. A private Layer 2 link or a dedicated wavelength keeps it on a circuit only your sites use. Encrypted tunnels over internet circuits protect general branch traffic in transit.

Steady performance for priority traffic

MPLS gave video calls and transactions a priority class across the provider's network. An alternative needs its own way to protect latency-sensitive apps, either through a dedicated circuit with reserved capacity or through SD-WAN policies that steer each app to the best path available.

Direct reach to cloud platforms

Traffic bound for cloud apps should take the shortest path. Branches can send it straight out over local internet circuits, and data centers can use private connections into the clouds they depend on most.

Reach in every country you operate

Internet quality and regulation vary by market. The same survey found that organizations keep MPLS heavily in regions like China and Africa because of geopolitical challenges, poor internet options, and regulatory complexity. Elsewhere, teams source internet access market by market across sites and countries. Across all regions, the State of the Network 2025 report found that only 15% of companies source their DIA from a single provider, compared with 27% for MPLS.

Layer 2 Ethernet for private site-to-site links

Layer 2 Ethernet connects sites as if they shared one switch. The provider carries Ethernet frames between your locations, and your own routers handle the routing. Mplify, the standards body formerly called MEF, defines these services as point-to-point, multipoint-to-multipoint, or rooted-multipoint, each either port-based or VLAN-based.

Point-to-point service suits a pair of sites with steady traffic, such as headquarters and a data center. Multipoint service, often delivered as VPLS, links three or more sites in one Layer 2 domain. Each option trades ports, VLAN planning, and site counts differently, and a side-by-side comparison of EPL, EVPL, and VPLS shows where each one fits.

Compared with an MPLS IP VPN, Layer 2 service hands routing control back to your team. Providers often build it on an MPLS core, so the change is who routes your traffic, and the traffic still stays on a private network.

Dark fiber and wavelengths for high-capacity routes

Some routes carry more traffic than a standard Ethernet service is sized for. Data center replication, campus backups, and links to large storage or compute clusters can fill 100 Gbps and keep growing, and two options cover them.

• Dark fiber: You lease or buy unlit strands and supply your own optics, so you set the capacity, control every upgrade, and take on the equipment, its upkeep, and the staff to run it.
• Wavelengths: A provider lights the fiber and sells you a dedicated wavelength at 100G, 400G, or 800G, which gives you a private, high-capacity link without owning the optics.

Where no fiber runs between your sites, someone has to build a new path or splice into an existing one. The choice between owning the fiber and buying it lit turns on control, staffing, and contract length, and the step from 100G to 400G waves depends on how fast each route grows.

SD-WAN over dedicated internet access

SD-WAN builds an overlay across whatever circuits a site has. Mplify defines an SD-WAN service as one that "creates an overlay network over one or more Underlay Connectivity Services," so SD-WAN still depends on good transport underneath. Dedicated internet access is the usual primary underlay, with broadband or wireless backup for branch sites as the second path.

Most enterprises now run SD-WAN. The same survey found that 63% of respondents have it deployed and another 15% are rolling it out. The overlay steers each app to the best circuit, encrypts traffic between sites, and sends cloud traffic straight to the internet.

SD-WAN fits branches, stores, and offices where most traffic goes to cloud apps. The SD-WAN versus MPLS tradeoffs matter most at the branch edge, and the Layer 2 and fiber options above usually carry the core.

MPLS alternatives compared side by side

Each MPLS alternative solves a different part of the network. Cloud reach depends on where each option ends, and private connections into cloud platforms can join any of them at a data center or hub.

Many multi-site networks run two or three of these at once.

How to replace MPLS one group of sites at a time

Teams that replace MPLS in stages move one site group at a time, timed to contract end dates, keeping each step small enough to test and reverse. Each stage's end date keeps MPLS migration overlap short and limits the cost of a fragmented network. The six steps below set up the plan once, then repeat the pilot and cutover for each group.

• Map contracts and routes: List every MPLS circuit with its term end date, its bandwidth, and the traffic it carries.
• Sort sites into groups: Group branches, hubs, data centers, and plants, and pick the alternative that fits each group.
• Connect hubs to both networks: Keep data centers reachable from MPLS and the new design, so a site that has moved can still reach a site that hasn't.
• Pilot one group: Move a small set of sites first, and run the new circuits beside MPLS until performance holds.
• Cut over at renewal: Turn off each MPLS circuit at its term end, so no site pays for two networks longer than it needs to.
• Keep MPLS where the market requires it: Leave MPLS in regions where local internet can't meet the requirement yet, and review it at the next renewal.

Pick the right path for every route

MPLS now covers about a fifth of the average WAN manager's sites, and the remaining routes are often the hardest to move. Each one needs an MPLS replacement that fits what it carries, in a market that may offer few carrier choices.

Momentum designs and runs MPLS alternatives across whole networks. We source dedicated internet from the best of 750+ carriers and service providers, run managed SD-WAN on Juniper Networks, Cisco Meraki, Arista Networks, and Cato Networks, and deliver private Layer 2 links between sites and point-to-point fiber at 100G, 400G, and 800G. When a route has no fiber, we lay our own and splice into carrier networks. We recommend the right route even when it isn't ours, and one team and one contract cover every site that moves.

Pull your MPLS circuit list with each term end date and the traffic each route carries. Then book a meeting, and we'll match each route on that list to the best alternative and set the order for your move.

FAQs

Can SD-WAN replace MPLS on its own?

For branch sites with mostly cloud traffic, SD-WAN over dedicated internet often replaces MPLS completely. SD-WAN is an overlay, so it depends on the underlying circuits. Routes that need fixed high capacity or a strictly private path, such as data center replication, usually move to Layer 2 Ethernet, wavelengths, or dark fiber instead.

Is internet-based WAN traffic as private as MPLS?

Not in the same sense. SD-WAN encrypts traffic between sites, so data crossing the internet is protected in transit. MPLS keeps traffic on a provider's private network and doesn't encrypt it by default. Teams whose contracts or policies require a private path for certain data keep that traffic on Layer 2 Ethernet or a wavelength, and send general branch traffic over encrypted internet tunnels.

Can you run MPLS and its replacement side by side?

Yes, and migrations usually do for a while. A hybrid design keeps MPLS at some sites while others move to SD-WAN or private links. Data centers or hubs stay reachable from both networks, so sites on each side can still reach each other. The overlap ends as each MPLS circuit reaches its term end and its site group finishes testing.

Does replacing MPLS change how you reach cloud apps?

Usually it does. MPLS designs often send branch traffic to a central data center before it reaches the internet. With SD-WAN, branches can send cloud traffic straight out through local internet circuits. Data centers and hubs can add private connections to cloud platforms such as Microsoft Azure or AWS, so heavy or sensitive cloud traffic stays off the public internet.

Do MPLS alternatives work across countries?

They do, though the mix often changes by region. Internet quality, carrier choice, and regulation vary by market, and some organizations keep MPLS longer in regions such as China and Africa for those reasons. A multi-country plan can run SD-WAN over local internet in strong markets, private links where policy requires them, and MPLS where no local option meets the requirement yet.
