Ethernet services climbing
Businesses around the world are rapidly increasing their investments in advanced Ethernet services to handle growing bandwidth needs and rising security concerns. This is especially the case for Ethernet virtual private LAN service and multi-protocol label switching IP virtual private network platforms.
A recent study from TeleGeography found both service types are rapidly growing as popular technologies, but MPLS IP VPNs are reaching a larger quantity of customers.
According to the study, Ethernet VPLS technology is not available in nearly as many countries as MPLS IP VPNs. The study analyzed service providers that reach customers in 63 different countries. More than half of those service providers offer MPLS IP VPNs in 10 or more countries. Ethernet VPLS is not nearly as wide-spread, with less than one-third of service providers in the study offering the service.
Overall, the study found the availability of Ethernet-based services tends to be closely tied to the economic status of the country. In developed economies, advanced Ethernet VPLS platforms are available as well as MPLS IP VPNs. These economies support numerous Ethernet- and IP-based services. However, nations with emerging economies see significantly less Ethernet availability and often must settle for less sophisticated networking technologies, the study found. In most cases, the proportion of Ethernet-based deployments was directly tied to the region's economic maturity.
The TeleGeography study found that the trend toward IP-based services in emerging economies is somewhat out of line with economic conditions because Ethernet services are often less expensive to deploy. However, the study also noted that most cities in these countries lack the Ethernet infrastructure necessary to support large-scale Ethernet deployments. This has slowed Ethernet adoption compared to IP-based systems, but both are still growing in emerging and developing economies.
Growth in Ethernet VPLS and MPLS IP VPNs comes at the expense of many legacy technologies that are on their way out in many global markets. The study found private lines, frame relays and ATM WANs are all on the decline in light of more contemporary technologies.
As more businesses deploy advanced Ethernet infrastructure, the need for performance monitoring is rapidly becoming critical. A recent TMCNet report explains the growing popularity of Ethernet services is creating more need for performance monitoring in Ethernet backhaul equipment. This should help companies manage their networks more efficiently by handling the growing amounts of internet traffic in enterprise and data center settings.
