Carriers expand WAN offerings, but coverage disparities persist

5 Feb 2015

As data networks become an increasingly critical component of international enterprises, carriers are expanding their portfolio of IP VPN and Ethernet wide area network (WAN) service offerings and their geographic coverage. However, new data from TeleGeography’s Global Enterprise Networks Research Service reveal that on-net service coverage varies widely by technology and geography.

IP VPN remained the most ubiquitous WAN service globally in 2014, with 5,170 instances of carriers offering on-net service in the 2,891 cities covered in the study. Ethernet over MPLS (EoMPLS), the most widely offered Ethernet point-to-point technology, was next, with 3,431 instances of on-net service, followed by Dedicated Internet Access (DIA) and EVPN, with 3,175 and 3,020, respectively.

IP VPN was also the most widely available WAN service in 166 key international business centers analysed in TeleGeography’s study. However, regional disparities in availability are apparent. While on-net IP VPN service was available from an average of six carriers per city in Latin America and the Caribbean, and seven in Africa in 2014, more than twice as many carriers offer such service in major cities in Asia, Europe, and the US and Canada.

Differences in the regional availability of EoMPLS, EVPN, and DIA service are even more stark. In major markets in Europe and the US, buyers can choose from an average of 13 to 16 EoMPLS and EVPN service providers per city, and twelve to 14 DIA providers. In key cities in the Asia-Pacific region, EoMPLS and EVPN were offered by an average of eight providers per city, while DIA was offered by six. Availability of these services in Latin America and the Caribbean and Africa is still far more limited, even in the largest cities. On-net EoMPLS, EVPN, and DIA service was available from an average of just two to four providers per city in these regions.

‘Carriers are investing in PoPs and deploying equipment in new geographies to meet customer demand for next generation services,’ said TeleGeography analyst Brianna Boudreau. ‘As this continues, developing countries will see greater availability of Ethernet services and more IP VPN providers, and disparities in on-net coverage will begin to erode.’

TeleGeography’s Global Enterprise Networks details the international enterprise network services offered by 134 service providers in 2,891 cities and 207 countries, and analyzes trends in enterprise service availability and pricing. Service offerings covered include MPLS IP VPN, Ethernet, DIA, and private line services.
