    摘要: A method and apparatus for realizing service protection are provided. The method includes the following steps: determining paths corresponding to automatic protection switching (APS)/protection communication channel (PCC) overhead bytes that are available to all nodes in a service protection trail; selecting a path for service protection from the determined paths corresponding to the APS/PCC; and using the selected path for implementing the service protection. Therefore, it is ensured that several service protections using APS/PCC may coexist in an optical transport network (OTN) and different kinds of service protection can be easily distinguished from one another.

    摘要: A method for realizing interaction of optical channel data unit (ODUk) protection tangent rings are provided. A node used for protection of the ODUk and a receiving unit, a sending unit, a protected receiving unit and a protected sending unit on the node are selected. A connection between a receiving service unit and the protected sending unit with the same transmission direction on the node is established, or a connection between a sending service unit and the protected receiving unit with the same transmission direction on the node is established. Two virtual nodes are established on the node if the node is an intersection node, and connections between the receiving service unit and the protected sending unit, and between the sending service unit and the protected receiving unit are established respectively in each direction of both directions through one of the virtual nodes.

    摘要: Embodiments of the present invention disclose a service transmission processing method, a node device and a network system are provided. One method includes: receiving service data after relay processing by a 3R relay node, where the relay processing includes terminating and regenerating an Optical Channel (OCh) of the service data, and when the OCh is terminated, transparent transmission is performed on an Optical channel Transport Unit (OTU); and performing defect detection on a path of the OTU to obtain a detection result of the path of the OTU. Another method includes: obtaining an overhead in an Optical Transport Network (OTN) frame; and judging whether the overhead includes a Client Signal Fail (CSF) inserted after a signal fails, and if the overhead includes the CSF, determining a path where a defect occurs according to the CSF.
