Ethernet-dedicated Internet Access is a continuous, high-bandwidth method for enterprises to connect their local area networks (LANs) with the public Internet and streamline the performance of their wide area network (WAN). Ethernet-dedicated Internet Access (Ethernet DIA) is also called dedicated Ethernet, dedicated Internet, business Ethernet or enterprise Ethernet. 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. 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. Traditionally, enterprises relied on T1 access to the Internet. 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. A relatively new alternative, Ethernet DIA is ...
