Service-grade Ethernet is a essential piece of right this moment’s enterprise WAN, and carriers proceed to develop their community footprints and make larger capacities out there.
TeleGeography’s newest Bandwidth Value Report—drawn from our Community Pricing Database—takes a deep dive into Ethernet’s place within the WAN and analyzes current pricing tendencies throughout geographies and capacities, specializing in Ethernet over MPLS (EoMPLS) and Ethernet over DWDM (EoDWDM).
With multiple possibility for larger capability companies, how do you select what’s finest on your WAN?
There’s a lot to contemplate because the market and the connectivity panorama change, however the fundamentals of those companies stay the identical. DWDM is an unprotected path, whereas EoMPLS is taken into account a pseudowire, with a mesh that gives redundancy that may simply reroute visitors in case of an outage.
Redundancy and variety are two phrases that we hear again and again. So, what’s all of the fuss? For extra on this subject, don’t miss subsequent week’s Capability Europe panel dialogue, “Submarine cable routes: why diversify?” that includes my colleague Rob Schult.
Till then, preserve studying to pattern our evaluation.
The Marketplace for 10 GigE
It’s regular to routinely consider wavelengths as soon as 10 Gbps is required. As MPLS core backbones have elevated in scale, extra carriers are providing high-capacity companies.
The most typical use case for 10 GigE EoMPLS is connectivity between knowledge facilities, and it may also be useful between an information middle and a catastrophe restoration middle. When deciding between EoDWDM and EoMPLS for 10 GigE, there are essential elements to contemplate past value.
When deciding between EoDWDM and EoMPLS for 10 GigE, there are essential elements to contemplate past value.
DWDM connections are offered over optical wavelengths with Ethernet interfaces into the shopper change or router. It’s vital to notice that so as to make the most of Ethernet over DWDM, there must be this translation between an area loop to a DWDM, so you possibly can have an Ethernet handoff.
When a buyer chooses two various DWDM paths for cover—versus EoMPLS—additionally they need to handle the failover, or the power to change routinely and seamlessly to a dependable backup system. Finally, this angle may help clarify why unmanaged waves could be supplied at larger capacities for decrease costs, and why a managed and guarded EoMPLS service typically instructions a premium.
Now, if the added safety is just not a precedence, it’s doable to run a single wavelength with Ethernet between knowledge facilities. Within the beneath determine, we are able to see how unprotected DWDM and EoMPLS costs examine on the 10 Gbps degree throughout main worldwide routes.
Median 10 Gbps DWDM and 10 GigE EoMPLS Month-to-month Costs on Key International Routes
Notes: Every darkish blue column represents the weighted median month-to-month lease value for an unprotected 10 Gbps wavelength on the listed route, and every turquoise column represents the median month-to-month lease value for 10 GigE EoMPLS. Costs are in USD and exclude native entry and set up charges. Knowledge as of Q2 2024. 10 Gigabit Ethernet (10 GigE) = 10,000 Mbps. Supply: © 2024 TeleGeography
Throughout all seven routes, EoMPLS instructions a premium over DWDM, starting from 19% on London-New York to 64% on Hong Kong-Singapore. Observe that this determine represents our medians, and never all reporting carriers supply each companies on every route.
When evaluating pricing from carriers who supplied each companies on these routes, EoMPLS got here at a premium in comparison with unprotected EoDWDM in most situations, though there have been examples on the contrary. For some carriers, EoMPLS costs have been as excessive as 5.4x the value of DWDM on Marseille-Singapore, and three.6x the value of DWDM on Los Angeles-Tokyo. Examples of service reductions for EoMPLS have been best on London-New York at 48%, and Los Angeles-New York at 30%.
Evaluating an unprotected DWDM to EoMPLS is somewhat bit like evaluating apples to oranges. For DWDM to have related redundancy and high quality of service as EoMPLS, it could require two separate wavelengths with various routing, in case of an outage. And that makes the typical premium of 43% for EoMPLS throughout these routes fairly affordable for purchasers requiring SLAs. Once we multiply these DWDM medians by 1.6 for redundancy, EoMPLS is less expensive on all routes besides Hong Kong-Singapore at $4,142.
Increased capability EoMPLS pricing schemes are diversified and nonetheless coming to fruition, however a number of tendencies have emerged.
