ZTE CMPP : SDH-Like OAM PW层次的OAM分为两种，一个是针对CES的（TDM：PDH/SDH）,h可能只能检测其连接性，性能无法检测，我们都可检测。 第二是，针对ETHERNET业务的PW层次OAM，我们也有。 PW损坏，LSP是无法检测出来的，所以，LSP tunnel层次的OAM，与PW层次的用途不同，PW层次的OAM并不能由LSP的OAM替代。 而有了段层的OAM，才有了环网保护。 另外，没有段层保护，就没有办法进行LSP的捆绑。如果每个LSP的OAM占用0.2M带宽，那么1000个LSP的OAM需要0.2M*1000。如果用了捆绑，1000个LSP的OAM只需0.2M。因此大量节省带宽。 ZTE CMPP provide SDH-like OAM 1/MPLS-TP layer structure: TMC/TMP/TMS as per the PW/ LSP Tunnel / Section 2/ Hierarchical OAM : PW layer/ Tunnel layer / Section layer for easy OAM. Diff layer OAM frames are inserted layer by layer from PW to Section. It is driven by hardware engine very 3.3 ms. Fault-detection and fault-location is easy and clear just like what SDH does. 3/ 50ms PS mechanism and hierarchical protection for high reliable. The OAM hardware engine inserts OAM frame very 3.3 ms and completes the continuity detection within 10ms./ 3 frames. and ensure the 50ms switching and protection. The protection includes PW layer / Tunnel layer / Section layer protection. It’s a hierarchical protection mechanism like what SDH does for POH layer, MSOH layer and RSOH layer. ************************************************************ Operations Administration and Maintain, Hierarchical OAM Similar to SDH Different from Hierarchical OAM is a very OAM engine guarantee based on hardware: The hardware inserts OAM detection package at every 3.3ms, completes continuity detection within 10ms and ensures sub-50ms switching. No increase in CPU overhead and no impact on CPU forwarding efficiency. CPU does not affect switching group number. Hierarchical monitoring like SDH, fast fault-detection and fault-location Multi-layer protection, high reliable ************************************************************ 动态功能目前不支持，请参见路标 IPTN 6000系列作为用户的接入层面，充分考虑部署，设备的摆放，安装， 耗能等因素，体积小巧，设备轻便，灵巧的单板子卡，小于300mm深的设计，可轻松容身与小型室外机规和相应的室内机规，真正的绿色产品，绿色运维的设计。 IPTN 9000系列采用APC自动功率控制，CAN总线全程整机智能监控，功耗智能动态调整系统，支持风扇可调无级变速，端口级功耗自动调整，实现了每端口功耗的业内最高节能水平。结合体积小、重量轻和容量大等优点，能够帮助运营商有效地节省能源
