LTE时代承载网发展研究

随着LTE的发展和部署,承载网络也需要相应发展。PTN网络开启L3 VPN后,如何实施业务的保护、PTN网络如何满足1588V2的传递等均是承载网络的发展方向。另外,运营商正在对POTN、SDN等新技术的开展深入研究,并进行了试点工作。同时,OTN网络也在向大带宽、智能化方向发展,从10G发展到100G,超100G技术也逐渐成为时下研究的热点。

Research on bearer network development in LTE era

With the development and deployment of LTE, transport network also needs corresponding development. After L3 VPN used in PTN, protections of services and delivery signals of 1588V2 through PTN become the trend of transport network. Besides, telecom service providers are doing further research on new technologies, such as POTN and SDN, which have already been applied in transport networks of several cities. Meanwhile, OTN is developing into the direction of large bandwidth and intelligence. Although the bandwidth has been widened from 10G to 100G, the technology of over-100G becomes a hotspot of research.
