同步光网络

同步光网络（SONET）的概念出现于1984年，它的提出主要用于消除不兼容的光接口，并逐步发展成为一种全新的传输网络技术体制。

In 1984 , the Synchronous Optical Network was proposed to eliminate mutually exclusive of the light interface , and it was marked as a kind of brand-new transmission network technology system .

采用FPGA芯片设计开发了基于CAM的协议引擎原型，仿真、综合后的结果表明它能满足OC-48同步光网络对输入分组进行快速分类的要求。

A CAM-based high-speed policy engine has been successfully designed and developed using FPGA , result of simulation and synthesis indicates it is able to execute high-speed packet classification preferably under OC-48 optical network circumstance .

SDH是一种将复接、线路传输及交换功能融为一体、并由统一网管系统操作的综合信息传送网络，是美国贝尔通信技术研究所提出来的同步光网络。

SDH is one kind the multiple connection , the line transmission and the exchange function merges into one organic whole , and by the unification network management system operation comprehensive information transmission network , is synchronized light network which American Bell Communication Research institute raises .
