Business Ethernet, Bought the Way It Should Be: Providers Competing for You

Business ethernet is what you buy when the requirement is not internet access but connecting your own locations to each other, or reaching a data centre or a cloud on-ramp privately. This hub explains the service types, when each one fits, and how to put carriers in competition for the network.

Ethernet Is Transport, Not Internet

This is the distinction that causes the most confusion, and it is worth being precise about. An ethernet service moves traffic between points you specify. It does not, by itself, connect you to the internet. Many buyers want both and end up purchasing internet access delivered over an ethernet handoff, which is a different product from an ethernet transport service.

The value of transport is that the traffic never touches the public internet. Two of your offices connected by ethernet behave like one network: same address space, no encryption overhead, latency that is predictable because the path is engineered rather than routed dynamically.

That is why ethernet remains the foundation for organisations that move large volumes between sites, run applications that assume a local network, or have regulatory reasons to keep traffic off shared infrastructure.

The Three Shapes Ethernet Comes In

Carriers use standardised names for these, and knowing which one you are asking for saves a great deal of back and forth.

Which Shape Your Network Actually Needs

Most buyers start by asking for point-to-point links between every pair of sites, which is the most expensive way to build almost any network. Draw the traffic first: if most of it flows between branches and one central location, hub and spoke costs considerably less and behaves identically for that pattern.

Full mesh is worth paying for when sites genuinely exchange traffic directly with each other and the volume is high enough that routing it through a hub would create a bottleneck. That is less common than it sounds, and it is easy to test by looking at where traffic actually goes today.

The other question is whether you need transport at all. If sites mostly reach cloud applications rather than each other, internet access at each location with SD-WAN over the top often delivers the same result at lower cost and with far quicker installs.

Speeds, Handoffs and the Things That Delay Installs

Ethernet services scale in defined steps rather than continuously, which is one of their advantages: increasing capacity on an installed circuit is frequently a configuration change instead of new construction. Ask where the steps are for the service you are buying and what moving between them costs.

The handoff is where installs go wrong more often than anywhere else. It is the physical interface the carrier presents in your building, and the connector type, optics and whether it is copper or fibre all have to match what your equipment expects. Confirm this in writing before install day, because a mismatch turns a working circuit into a delivery that cannot be connected.

Ask about the MTU as well. Ethernet services frequently support larger frames than the public internet, which matters for storage replication and backup traffic, but only if it is configured end to end.

When One Carrier Cannot Reach Every Site

Any network spread across regions eventually hits the limits of a single carrier's footprint. There are two ways through this and they carry different trade-offs.

One carrier can wholesale the last mile from another to reach a site outside its territory. That preserves a single contract and one support number, at the cost of longer repair times when the fault lies in the borrowed segment, because your provider must escalate to a company you have no relationship with.

Alternatively you can contract regionally with the carrier that owns the network in each area and stitch them together yourself, which gives better repair times and worse administration. Neither answer is wrong. The mistake is not knowing which one you have bought, so ask directly which segments are on-net and which are wholesaled.

How the Ethernet Marketplace Works

Ethernet quotes depend on both ends of every link, so the comparison only works when every carrier is pricing the same set of locations.

• Give us every locationBoth endpoints of each link drive the price, so partial lists produce misleading quotes.
• Carriers price the whole networkIncluding which segments they own and which they would wholesale.
• Compare footprint and repair termsNot just the monthly rate. Who owns each segment decides your bad day.

What to Check Before You Sign

Ethernet contracts tend to cover several sites at once, so an unnoticed detail multiplies.

• What is the handoff at each site? Connector, optics and media. Confirm in writing before install day.
• Which segments are wholesaled? It determines repair times more than the SLA percentage does.
• What MTU is supported end to end? Larger frames help replication and backup, but only if configured throughout.
• How does capacity scale? Ask where the steps are and what moving up costs mid-term.
• Is this transport or internet access? If you need both, confirm explicitly that internet is included.
• Is there a class of service option? Prioritising voice or video across the link usually costs extra and must be requested.
• What does adding a site later cost? Networks grow. Establish the process and pricing before you need it.
• Do all sites share a term end date? Staggered dates make renegotiating the whole network difficult.
