Comparison

MPLS vs Point-to-Point Fiber

MPLS is a provider-managed Layer 3 network: many sites join it and the provider routes between them, which scales elegantly as site count grows. Point-to-point circuits are dedicated Layer 2 links between specific site pairs that you route yourself, which gives you control and predictable performance on the paths that matter. Few sites with heavy traffic between specific pairs favours point-to-point. Many sites needing any-to-any reachability favours MPLS or a modern SD-WAN overlay.

This decision is usually framed as a technology comparison and is really an operating-model comparison. MPLS puts the provider inside your routing; point-to-point leaves routing entirely with you. Both are defensible, and the right answer depends far more on how many sites you have and who runs your network than on the underlying transport.

It is also worth saying plainly that MPLS is a mature technology in gradual decline for enterprise WAN, displaced by internet-plus-SD-WAN designs for many use cases — though not for all of them.

What actually differs

The mesh problem

Point-to-point scales badly if every site needs to reach every other site — a full mesh across n sites needs n(n−1)/2 links, which is fine at three sites and absurd at fifteen. This is precisely the problem MPLS was designed to solve. But most real networks are not full meshes: they are hub-and-spoke with a few heavy pairs, and for that shape a handful of circuits plus internet connectivity is simpler and cheaper.

What you give up with MPLS

Control, mainly. The provider participates in your routing, so changes go through their process, and classes of service are theirs to define. That is a fair trade for organizations without a network team and a poor one for organizations with a strong one. The second consideration is cost per megabit, which is generally high compared with dedicated circuits or internet transport.

What SD-WAN changed

SD-WAN made it practical to build a managed-feeling overlay across ordinary internet connections and dedicated circuits alike, steering traffic by application and failing over automatically. Many organizations that would have bought MPLS a decade ago now run SD-WAN over a mix of dedicated circuits and broadband, keeping the determinism of circuits on the important paths and the cost of internet everywhere else.

A pragmatic hybrid

Dedicated point-to-point circuits between the two or three site pairs with heavy or latency-sensitive traffic, dedicated internet at each site, and an SD-WAN overlay tying it together. You get deterministic paths where they matter, cheap capacity where they do not, and one routing policy across the whole estate.

Where the service commitment actually sits

On a point-to-point circuit the commitment is about one path between two known endpoints, which makes it easy to state and easy to verify: either the path met its rate and availability or it did not. On an MPLS network the commitment is usually expressed per site against the cloud rather than per site-pair, so a slow path between two particular branches can sit entirely within the terms while being the thing actually hurting you. Neither is dishonest, but they are answering different questions, and comparing the two numbers directly is misleading.

Neither one encrypts your traffic

This is the most common misunderstanding in the comparison. Both keep traffic off the public internet and separate from other customers, and that is a meaningful reduction in exposure — but separation is not encryption. Anyone with access to the path or the provider equipment is a risk that isolation alone does not address, and most compliance regimes ask whether data is encrypted in transit rather than whether the path is private. Plan to encrypt sensitive traffic on either topology, size the endpoints for it, and treat the private path as defence in depth rather than as the control itself.

Where the cost curves cross

Two or three sites connected pair-wise is usually cheaper and simpler as circuits. The arithmetic changes as sites multiply: a full mesh needs a circuit for every pair, while an any-to-any service needs one port per site regardless of how many other sites exist. Most organizations do not need a full mesh — a hub-and-spoke of circuits into a data centre or colocation facility covers a great deal of real traffic at lower cost. Work out which sites genuinely need to talk directly to which others before pricing either model, because the topology you actually need is often smaller than the one you were about to buy.

Choosing between them

MPLS fits when

  • You have many sites needing any-to-any reachability
  • You prefer the provider to operate routing between sites
  • Traffic is distributed rather than concentrated on a few pairs
  • Provider-managed classes of service meet your requirements
  • An existing MPLS estate makes migration cost unattractive

Point-to-point fits when

  • A small number of site pairs carry most of the traffic
  • You want Layer 2 transparency and full routing control
  • Deterministic performance on specific paths is the requirement
  • You already operate your own network equipment competently
  • Cost per megabit on the heavy paths matters

What we would recommend

For two sites, or a handful of sites with clear traffic patterns between known pairs, point-to-point paths are simpler, cheaper to reason about, and easier to hold someone accountable for. MPLS earns its complexity once the site count grows and any-to-any reachability with per-class treatment becomes a genuine requirement rather than a nice idea. We build point-to-point, so treat that as disclosed interest — but the site count and the traffic matrix decide this, not the vendor.

Decision checklist

Six questions that settle this choice faster than a feature table. The answer to each one tells you something the specifications do not.

  1. 1

    How many sites need to reach how many others, directly?

    Draw it. If the picture is mostly spokes into one or two hubs, circuits are likely cheaper and simpler than any-to-any.

  2. 2

    Do you need traffic classes honoured across the network?

    Guaranteed classes of service across many sites is the strongest MPLS argument. A single circuit hands you all of the capacity and lets you do your own queuing.

  3. 3

    How often do sites open, close or move?

    Frequent change favours a service that provisions a port. Stable, long-lived pairs favour circuits.

  4. 4

    Is encryption required in transit?

    If yes, budget the endpoint capacity for it on either option — neither topology provides it for you.

  5. 5

    Who runs the edge?

    MPLS commonly includes a managed edge router. Circuits assume your team terminates and configures both ends.

  6. 6

    What does the connectivity do if the provider network has a bad day?

    Ask how each option fails and what the second path is. Any-to-any services can mask a shared dependency that circuits make visible.

Frequently asked questions

Is MPLS obsolete?

No, but its role has narrowed. Internet-plus-SD-WAN handles many enterprise WAN requirements at lower cost, and MPLS remains relevant where many sites need managed any-to-any connectivity or where an organization genuinely wants the provider inside its routing.

Can point-to-point circuits carry multiple VLANs?

Generally yes — a Layer 2 circuit is transparent to what you send across it, so VLAN tagging typically passes through. Confirm the specifics with any provider, since implementations differ on frame size and tagging behaviour.

What about latency between distant sites?

Distance sets the floor regardless of technology — light in fiber travels at roughly two-thirds the speed of light in vacuum, which is about 5 microseconds per kilometre each way. A dedicated circuit gets you close to that floor consistently; a routed path adds hops and variability on top of it.

Still not sure which fits?

Describe what the connection has to carry and where. An engineer will tell you which service actually fits — including when the cheaper option is the right one.
