Examples of the present disclosure provide a dual-homing protection method and device. In the dual-homing protection method, a forwarding item synchronizing channel and a data transfer channel are established between two Provider Edge (PE) devices in a dual-homing node, a Pseudo Wire (PW) and a Label Switched Path (LSP) protection group bearing the PW are established between a network side peer PE device and the two PE devices in the dual-homing node, which are taken as a logical device, so as to implement LSP protection within a network. The present disclosure may enable the protection within a network to be independent of access link protection. Subsequently, the management is simple.

The present invention provides an apparatus and method for processing a packet. An interface processing module selects one from all service processing modules as a service processing module for processing a packet; if the service processing module needs to perform tunnel processing for the packet, the service processing module transmits the packet after performing the tunnel processing; if another service processing module needs to perform tunnel processing for the packet, the service processing module transmits the packet to a service processing module needing to perform tunnel processing for the packet. According to the present invention, the packet can be processed uniformly by the service processing module, so it is not unnecessary to store session states in the service processing modules, and also not unnecessary to perform synchronization between the service processing modules, which greatly decreases complexity of processing the packet and saves system bandwidth.

An apparatus and method for ensuring distributed packet transmission security are provided. In an embodiment of the present invention, a main control board allocates SA information to multiple processing boards according to a pre-defined criterion, so that each processing board which receives and stores the SA information may implement IPSec processing. As such, the IPSec processing is shared by the multiple processing boards. Accordingly, when there are a large number of IPSec tunnels on one interface, the IPSec processing to the packets passing the IPSec tunnels will not completely rely on only the processing board where the interface is located. Instead, the IPSec processing is allocated to different processing boards. Therefore, the multiple processing boards effectively share the IPSec processing corresponding to multiple SAs. The efficiency of the IPSec processing is increased.
