最早的以太网是在大约25年前开发出来的,其运行速度为每秒10兆位。但是到现在,首批能以每秒10000兆位速度运行的10G以太网交换机即将进入实用阶段。正如当初的以太网技术推动局域网发展达25年之久一样,10G以太网也将有力推动城域网的发展和推广,为各种类型、各种规模的企业提供最新的宽带应用。10G以太网将让应用服务提供商以及发展中的以太网本地交换公司(ELEC)更有效地参与竞争,在成本不变的前提下为他们提供100倍于T1线路的带宽。届时,ASP和ELEC通过一条以太网线所获得的营业收入要比那些提供现有T1线路服务的服务提供商多100倍,此外,过渡到高速以太网技术
The earliest Ethernet was developed about 25 years ago and runs at 10 megabits per second. But up to now, the first 10G Ethernet switches that can operate at 10,000 megabits per second are about to enter the practical stage. As the original Ethernet technology to promote local area network development for 25 years, 10G Ethernet will also contribute to the development and promotion of metropolitan area network for all types and sizes of enterprises to provide the latest broadband applications. 10G Ethernet will allow application service providers and the growing Ethernet Local Switching Company (ELEC) to compete more effectively, providing them with 100 times the bandwidth of T1 lines at the same cost. By then, ASPs and ELECs will earn 100 times more revenue over an Ethernet line than service providers that offer existing T1 line services. In addition, moving to high-speed Ethernet technology
