    摘要： A method and a device for transmitting an Optical Channel Transport Unit signal are disclosed in the present invention. The method includes: receiving an Optical Channel Transport Unit OTUk signal after photoelectric conversion; wrapping the OTUk signal into an Optical Channel Data Unit (ODU) signal; multiplexing and mapping the ODU signal to an Optical Channel Payload Unit OPUj signal, where the OPUj signal is a High Order signal of the ODU signal; and wrapping the OPUj signal into an ODUj signal and an OTUj signal, and sending the ODUj signal and the OTUj signal. Through the embodiments of the present invention, fully transparent transmission of an OTU signal can be implemented.

    摘要： A method, a device and a system for interconnecting a multi-protocol label switching (MPLS) network and an Ethernet are provided. A packet sent by a node located at the Ethernet is received, the packet is parsed, the parsed packet is re-encapsulated by means of MPLS, and the re-encapsulated packet is sent to a node located at the MPLS network, so as to implement interconnection between the MPLS network and the Ethernet. A reverse solution is similar to this. An intermediate node in the solution adopts a manner of parsing a packet and then re-encapsulating the packet when the packet is sent from one network to another network, instead of transparent transmission only. Therefore, it is unnecessary to configure a Media Access Control (MAC) address of a remote node on a node located at the Ethernet and to configure Ethernet information on a node located at the MPLS network.

    摘要翻译： 本发明提供一种方法，装置和用于互连的多协议标签交换（MPLS）网络和以太网的系统。 由位于以太网上的节点发送的分组被接收时，该数据包被解析时，所解析的分组由MPLS方式重新封装，并且重新封装后的分组发送到位于MPLS网络中的节点，以 实现MPLS网络和以太网之间的互连。 反向的解决方案是与此类似。 在该溶液中的中间节点采用而不是仅透明传输解析数据包，然后重新封装该分组当分组从一个网络传送到另一个网络的方式，。 因此，不需要配置位于以太网上的节点上的远程节点的媒体访问控制（MAC）地址，以及配置位于MPLS网络中的节点上的以太网信息。

    摘要： The present invention provides a method, apparatus and system for transmitting and receiving a client signal. The method for transmitting a client signal includes, at the transmitting end, mapping a client signal to be transmitted to a corresponding low-order Optical Channel Data Unit (ODU) in a low-order ODU set, wherein low-order ODUs in the low-order ODU set having rates increased in order, and having rate correspondence relations with the client signals; mapping the low-order ODU to a timeslot of a high-order Optical Channel Payload Unit (OPU) in a high-order OPU set; and adding overheads to the high-order OPU to form an Optical Channel Transport Unit (OTU), and transferring the OTU to an Optical Transport Network (OTN) for transmission.
