“By using a single technology, Ethernet, it sets aside much of the complexity of networking and enables the use of Ethernet at all sites-both on LAN and WAN. “These providers are now in direct competition with Verizon, and to a lesser extent AT&T, Level 3, and Century Link.” Advantages of using Ethernet DIA over other WAN technologies?Īt a basic level, Ethernet DIA is the same technology that enterprises use in their LANs, so the technology can use what enterprises already have implemented on their LANs and extend it to the WAN. offer Ethernet DIA, including “all of the big cable companies-Comcast Business, Time Warner Cable, Cox Communications, Charter, Optimum Light Path,” Chander said.
More than 40 service providers in the U.S. “An estimated 15% of enterprises are using Ethernet for dedicated Internet access today,” said Nav Chander, research manager of telecom services and networks, IDC. It provides the strong upstream and downstream speeds required for hosting a Web presence, which is the primary reason enterprises are buying it.Įven though this is still a new market, Ethernet DIA is taking off quickly. But as bandwidth requirements began doubling every year, many enterprises outgrew T1 and there was no logical way to grow or expand this type of Internet access.Ī relatively new alternative, Ethernet DIA is delivered over a single Ethernet fiber optic connection and boasts bandwidth ranging from 1 Mbps to 10 Gbps. Traditionally, enterprises relied on T1 access to the Internet. These legacy WAN links cannot handle escalating bandwidth requirements for cloud computing, business continuity, business process automation, software-as-a-service (SaaS) and other applications. No matter what you choose to call it, Ethernet DIA is an alternative to legacy technologies-such as T1 lines, frame relay and ATM-that typically rely on bonding multiple T1 lines or fractional T3 lines. Ethernet-dedicated Internet Access (Ethernet DIA) is also called dedicated Ethernet, dedicated Internet, business Ethernet or enterprise Ethernet.
