摘要
分组传输网(Packet Transport Network,PTN)是LTE网络建设的重要技术之一,随着IP化业务和高速数据传输的爆发式增长,其可靠性显得非常重要,尤其是与IPRAN实现混合组网,提高数据承载能力。目前,PTN和IPRAN混合组网业务保护采用的方式很多,比如双向1:1线性保护、单向1+1线性保护、VPNFRR保护、PW冗余保护、VRRP+IPFRR保护等,有效地保护数据传输的可靠性,还可以使PTN和IPRAN混合组网建设模式更加灵活,易于进行网络化管理。未来,随着大数据、数据挖掘技术的发展,还可以利用这些技术构建专家系统,提高PTN和IPRAN网络保护的性能,实现高清晰视频、高分辨率图像和实时语音数据传输。
Packet Transport Network(PTN) is one of the important technologies for LTE network construction. With the explosive growth of IP-based services and high-speed data transmission,its reliability is very prominent,especially with IPRAN to achieve hybrid networking,improve data carrying capacity. At present,PTN and IPRAN hybrid networking services are protected in many ways,such as bidirectional 1:1 linear protection,unidirectional 1+1 linear protection,VPNFRR protection,PW redundancy protection,VRRP+IPFRR protection,etc.,to effectively protect data transmission. The reliability can also make the PTN and IPRAN hybrid networking construction mode more flexible and easy to network management. In the future,with the birth of big data and data mining technologies,they can also use these technologies to build expert systems,improve the performance of PTN and IPRAN network protection,and achieve high-definition video,high-resolution images and real-time voice data transmission.
