探讨了IP业务在光通信中采用SDH技术进行传输及IPOverSDH技术在宽带信息网中的应用。IPOverSDH指的是IP PPP HDLC一组协议在同步光纤网上的传输 ,提高了点到点之间的传输速率 ,特别适合以IP业务量为主的宽带信息网或在电信骨干网上疏导高速率数据流。
It discusses the application of SDH technology in IP communication and the application of IPOverSDH technology in broadband information network. IPOverSDH refers to a group of IP PPP HDLC protocol in the transmission of synchronous optical networks to improve the point-to-point transmission rate, especially for IP-based broadband information network or the backbone of the telecommunications network to divert the high-rate data flow .
