随着对高带宽对称服务需求的增长,以太网接入解决方案变得越来越普及。厂商和电信运营商面临着将以太网加入电信公司本地环路所带来的相关技术和商业机遇。以太网接入使宽带客户,无论是商业还是社区用户,都能享受同局域网一样的高速对称服务。不久前,使用传统的宽带接入设备,包括ISDN和ADSL,还不能达到下游和上游从10Mbps to 100Mbps的线速。今天,VDSL和LAN接入等新技术的引入将双向高速网络连接变成了现实。
With the increasing demand for high bandwidth symmetric services, Ethernet access solutions are becoming more and more popular. Vendors and telcos face the technology and business opportunities associated with bringing Ethernet to the telcos’ local loops. Ethernet access to broadband customers, whether business or community users, can enjoy the same high-speed LAN symmetrical services. Not long ago, the use of traditional broadband access devices, including ISDN and ADSL, did not yet achieve downstream and upstream line rates from 10Mbps to 100Mbps. Today, the introduction of new technologies such as VDSL and LAN access turns bidirectional high-speed Internet connections into reality.
