POTN业务转发系统及业务转发、配置下发、保护方法
摘要：
本发明公开了一种POTN业务转发系统及转发方法，涉及POTN传输技术领域，包括以太网支路盘，交换盘和OTN线路盘；本发明上话方向将POVE实例化为组播来实现桥接，分组业务将该组播作为上话方向业务通道的出口，OTN业务将该组播作为与ODUK通道交互的源端口；下话方向将POVE实例化为VLANDOMAIN以实现桥接，OTN业务将与ODUK通道连接的线路侧背板口映射到该VLANDOMAIN，分组业务将该VLANDOMIAN作为普通的物理端口以完成接入分组业务的分类处理。本发明还公开了一种POTN业务转发方法。
摘要（英）：

The present invention relates to the technical field of POTN transmission, and disclosed are a POTN service forwarding system and forwarding method. The system comprises an ethernet tributary unit, switch unit, and OTN line unit. In the present invention, POVE is instantiated as a multicast in an uplink direction to enable bridge connection, a packet service employs the multicast as an exit port of an uplink service channel, and an OTN service employs the multicast as a source port of interaction with an ODUk channel. In a downlink direction, the POVE is instantiated as VLANDOMAIN to enable bridge connection, the OTN service maps a line-side backplane port connected to the ODUk channel to the VLANDOMAIN, and the packet service employs the VLANDOMAIN as a common physical port to complete classification for accessing the packet service. Also disclosed in the present invention is a POTN service forwarding method.
