.The geographic coverage of carriers’ enterprise network services varies significantly. Not every carrier connects to every city in their customers’ networks and not all services are available everywhere.
When narrowing down the universe of potential suppliers enterprises must first consider how their geographic requirements overlap a potential service provider’s physical network. They then must determine if the specific data services they require are enabl at each of the service providers’ PoPs.
TeleGeography’s WAN Services Coverage analysis—part of our Cloud and WAN Research Service—examines carrier network connectivity and service availability from a geographic perspective.
Heres a snippet of that analysis follow by some handy definitions
Global Business Center Product Comparison
Layer 3 MPLS IP VPN remains the most common enterprise-wide area network product across 165 key business center metros.
In these metro areas carriers present over 3000 offerings of this service.
EoMPLS is the second most common service in these locations with over 2500 offerings and DIA is third with over 2300 offerings. EVPN is offered over 2000 times in these metros and DWDM is offered over 1800 times.

Here are the definitions we use in our research
Any-to-Any/IP Networks
Any-to-any includes multipoint-to-multipoint or IP services typically sold as enterprise products.
Layer 3 IP virtual private network (VPN) is based on an MPLS network. IP VPN is a layer 3 IP-routed service that allows customers to set up a network of secure private connections that tunnel over the public IP or carrier network.
Carriers offer VPN beginning at low capacities such as 64 Kbps all the way up to 10 GigE (10000 Mbps). Because VPN can be routed over the public IP network and it allows for diverse access options it is typically thought of as the most geographically ubiquitous network product.
VPN is typically thought of as the most geographically ubiquitous network product
A key characteristic of VPN over MPLS is the ability to mark important packets with queuing instructions bas on their priority. This prioritization is call class of service (CoS).
For example a customer can pay an extra charge in addition to the port lease to have all of its voice and video packets marked with high priority CoS tags that allow these packets to skip to the front of the line at crowded routers in the core network.
Dedicat internet access (DIA) is the most basic IP service available to retail customers. It is simply an always-on uncontend pipe to and from the public Internet.
As with VPN the access options are generally wide and will determine the up/down speed ratios of the DIA service. DIA is sold as a port in the carrier PoP but should not be confus with access technologies such as DSL.
Unlike consumer grade IP service often sold to smaller businesses
DIA comes with service level agreements (SLAs) and speeds that the carrier guarantees will not vary with local usage rates as is the case with a contended service.
Ethernet virtual private network (EVPN) is the newest enterprise solution to emerge in long-haul Ethernet products. This layer 2 VPN service was formerly referr to as VPLS in our Cloud and WAN Research Service which is how some carriers still refer to it. It shouldn’t be confus with a legacy product of the same name and—as far as Tele Geography research is concern—is always a port-bas any-to-any service.
For many carriers the presentation of EVPN to the customer is very similar to VPN
EVPN however requires an Ethernet local loop which may limit its application geographically. EVPN essentially allows the customer to bring the. LAN to the provider edge where they can then connect the LAN directly to the wide area network.
EVPN allows sophisticated customers to create their own virtual paths over. The carrier’s MPLS core or multiservice platform therefore offering the ultimate in tunneling security since the customer can have control over routing within the cloud. Most carriers offer a CoS system for EVPN similar to that found in layer 3 VPN.
Long Haul Ethernet Private Line
This category includes point-to-point or observing and recording behavior or events point-to-multipoint Ethernet products excluding EVPN.
Ethernet over MPLS (EoMPLS) is a virtual private line that is tunnel through the MPLS network cloud.
Some carriers sell this in two ways either as a point-to-point
Service that would simply replace legacy TDM private lines or as a hub and spoke service that allows one central office to communicate with many kh lists satellites but does not allow communication among the satellite offices. In either case the layer 2 service is switch over the network cloud but approximates the security and privacy of a traditional private line.
