The geographic protection of carriers’ enterprise community companies varies considerably. Not each service connects to each metropolis of their prospects’ networks, and never all companies can be found in every single place.
When narrowing down the universe of potential suppliers, enterprises should first think about how their geographic necessities overlap a possible service supplier’s bodily community. They then should decide if the precise information companies they require are enabled at every of the service suppliers’ PoPs.
TeleGeography’s WAN Providers Protection evaluation—a part of our Cloud and WAN Analysis Service—examines service community connectivity and repair availability from a geographic perspective.
Here is a snippet of that evaluation, adopted by some useful definitions.
World Enterprise Middle Product Comparability
Layer 3 MPLS IP VPN stays the commonest enterprise-wide space community product throughout 165 key enterprise middle metros.
In these metro areas, carriers current over 3,000 choices of this service.
EoMPLS is the second commonest service in these areas, with over 2,500 choices, and DIA is third, with over 2,300 choices. EVPN is obtainable over 2,000 occasions in these metros, and DWDM is obtainable over 1,800 occasions.

Every of those 5 enterprise merchandise (plus SDH, EoSDH, and T-E companies) are most generally obtainable in Europe, adopted by the U.S. and Canada, after which Asia.
Variety of Choices of High Providers by Area in Key Metros
However what is the distinction between these eight merchandise?
Listed below are the definitions we use in our analysis.
Any-to-Any/IP Networks
Any-to-any contains multipoint-to-multipoint or IP companies usually offered as enterprise merchandise.
Layer 3 IP digital personal community (VPN), relies on an MPLS community. IP VPN is a layer 3 IP-routed service that enables prospects to arrange a community of safe, personal connections that tunnel over the general public IP or service community.
Carriers provide VPN starting at low capacities equivalent to 64 Kbps all the way in which as much as 10 GigE (10,000 Mbps). As a result of VPN will be routed over the general public IP community, and it permits for numerous entry choices, it’s usually considered essentially the most geographically ubiquitous community product.
VPN is usually considered essentially the most geographically ubiquitous community product.
A key attribute of VPN over MPLS is the power to mark vital packets with queuing directions based mostly on their precedence. This prioritization is named class of service (CoS).
For instance, a buyer pays an additional cost along with the port lease to have all of its voice and video packets marked with excessive precedence CoS tags that permit these packets to skip to the entrance of the road at crowded routers within the core community.
Devoted web entry (DIA) is essentially the most primary IP service obtainable to retail prospects. It’s merely an always-on, uncontended pipe to and from the general public Web.
As with VPN, the entry choices are usually broad and can decide the up/down pace ratios of the DIA service. DIA is offered as a port within the service PoP, however shouldn’t be confused with entry applied sciences equivalent to DSL.
In contrast to shopper grade IP service usually offered to smaller companies, DIA comes with service degree agreements (SLAs) and speeds that the service ensures is not going to differ with native utilization charges, as is the case with a contended service.
Ethernet digital personal community (EVPN) is the most recent enterprise answer to emerge in long-haul Ethernet merchandise. This layer 2 VPN service was previously known as VPLS in our Cloud and WAN Analysis Service, which is how some carriers nonetheless confer with it. It should not be confused with a legacy product of the identical identify and—so far as TeleGeography analysis is anxious—is all the time a port-based any-to-any service.
For a lot of carriers, the presentation of EVPN to the shopper is similar to VPN.
EVPN, nevertheless, requires an Ethernet native loop, which can restrict its software geographically. EVPN primarily permits the shopper to carry the LAN to the supplier edge, the place they will then join the LAN on to the broad space community.
EVPN permits subtle prospects to create their very own digital paths over the service’s MPLS core or multiservice platform, due to this fact providing the final word in tunneling safety for the reason that buyer can have management over routing inside the cloud. Most carriers provide a CoS system for EVPN much like that present in layer 3 VPN.
Lengthy Haul Ethernet Personal Line
This class contains point-to-point or point-to-multipoint Ethernet merchandise, excluding EVPN.
Ethernet over MPLS (EoMPLS) is a digital personal line that’s tunneled via the MPLS community cloud.
Some carriers promote this in two methods, both as a point-to-point service that might merely substitute legacy TDM personal strains, or as a hub and spoke service that enables one central workplace to speak with many satellites, however doesn’t permit communication among the many satellite tv for pc places of work. In both case, the layer 2 service is converted the community cloud, however approximates the safety and privateness of a conventional personal line.
Ethernet over SDH/SONET (EoSDH/SONET) is the power to supply the scalability and interface of Ethernet over an SDH/SONET line.
This service will be offered in each protected and unprotected kinds, much like conventional SDH/SONET. There are a number of benefits to EoSDH/SONET service, together with its potential to permit the shopper to attach the LAN on to the personal line slightly than engineer a conversion to SDH/SONET. The second key benefit is that it permits the shopper to purchase in smaller Ethernet increments equivalent to 10 Mbps slightly than buying 5 E-1s or a DS-3 with 35 Mbps of extra capability.
Lengthy Haul Personal Line
The companies listed beneath this part signify the legacy personal line applied sciences.
T/E Provider is a TDM T-1 (1.5 Mbps) or T-3/DS-3 (45 Mbps) line within the U.S., Canada, and Japan and an E-1 (2 Mbps) or E-3 (34 Mbps) line elsewhere. That is nonetheless a preferred product for patrons with smaller bandwidth necessities or fewer websites.
Synchronous Digital Hierarchy (SDH) and Synchronous Optical Networking (SONET) are the legacy TDM merchandise. SONET is used within the U.S. and Canada and SDH in the remainder of the world.
They’re offered for bigger bandwidth personal strains and will be offered as a linear connection, or extra usually as a full-circuit protected service that features a redundant numerous line for restoration.
Dense wavelength division multiplexing (DWDM) is a product that’s extra usually seen within the wholesale service market, since it’s at the moment offered primarily as 10 Gbps (or bigger) point-to-point connections.
Some enterprise prospects with very massive bandwidth wants (for instance, a headquarters needing to connect with a backup or information middle) might select this product. DWDM is usually offered as a linear or unprotected product.
When a 10G wave is protected, it might be offered as an STM-64/OC-192 SDH/SONET line. Additionally falling into this class is Ethernet over DWDM (EoDWDM) which is just a DWDM wavelength with an Ethernet interface.
Some carriers permit prospects to buy incremental capability. For instance, a buyer may buy a GigE that’s delivered over a 10G DWDM wavelength. In some instances, retail prospects should buy a full 10GigE personal line circuit.
