    摘要： A method for service protection is disclosed, which is applied to a 1:n switching technique. The method includes the following steps. A source end sends a service to a work transmission entity, the work transmission entity performs performance monitoring through the transmitted service, a sink end receives the service from the work transmission entity; when a Signal Degrade (SD) fault occurs at the work transmission entity, the source end sends the service to the work transmission entity and a protection transmission entity simultaneously, and the sink end selects to receive the service from the protection transmission entity; the protection transmission entity performs the performance monitoring through the transmitted service; when the SD fault occurs at both the work transmission entity and the protection transmission entity, the sink end still receives the service from the protection transmission entity. A system for service protection is also disclosed. Technical solutions enable the service to get valid protection during the transmission process, and avoid frequent switching of the service, thereby improving the service quality.

    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.
