Native hard pipe (NHP) is a TDM-based hard pipe that features high security, low latency, and deterministic experience. The NHP technology integrates the transport network and access network, implementing multi-network integration and bearing the power and transportation production network, video surveillance network, IoT network, and office network. Huawei OptiXtrans E6600 products are the main devices used on the NHP target network.
The NHP target network uses the VC technology to carry SDH services on the live network and uses the OSU technology to carry video and IoT services. This ensures 100% security and reliability of the power production network and supports smooth evolution to new bearer systems, promoting digital transformation of the power production network. Huawei OptiXtrans E6600 and OptiXtrans E9600 products fully support the NHP technology and are applicable to power transmission and transformation scenarios in the electric power industry.
The OSU over PON technology introduces NHPs to the access network. Different OSU hard pipes carry different network signals, implementing convergence of multiple networks. OSU hard pipes can ensure secure transmission and isolation of different network signals. With OSU hard pipes, the power distribution communication network can enjoy both the low-cost FTTM and high-quality experience of NHPs.
In railway scenarios, secure and reliable bearer communication networks are required for telephone, SCADA, GSM-R, LTE-R/5G-R, future information networks, and video surveillance signals. NHPs can carry multiple networks and provide 100% physical isolation capability to ensure secure and stable information transmission between networks and support secure and reliable operation of the entire railway service.
The development of smart subway services and video cloud drives the bandwidth improvement and architecture upgrade of subway bearer networks. The bandwidth of the bearer ring network will gradually increase from 100G to 200G or even 300G. The network architecture will be compatible with various service transmission modes, such as multicast and one-hop cloud access. In the Smart 300G solution, a 100G gray ring network can be constructed first, and then a 200G colored ring network can be deployed. This solution not only inherits the efficient multicast capability of MRPS, but also supports bearing and bandwidth expansion for one-hop cloud access services. In this way, efficient bearing of subway services is achieved.
