摘要： 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.

摘要： A source Medium Access Control (MAC) address is learned upon receiving a data message from a local network, and a learned local MAC address entry is added to a MAC address forwarding table. A source MAC address is not learned upon receiving a data message from a tunnel. When a local MAC address entry in the MAC address forwarding table changes, a synchronization message is sent via each tunnel associated with a Virtual Extensible Local Area Network (VXLAN) in the changed local MAC address entry, and is saved into a database corresponding to the tunnel. Each tunnel corresponds to one database.
