The interface unit 11 is connected to a connection external node and a designated port. The external node is a data input end of one service node, the designated port is a data receiving end of the other service node, and the external node and the designated port realize data exchange through an electric signal channel provided by the integrated security management switch. The interface unit 11 acquires the port address of the specified port according to the request signal sent from the specified port, and acquires the original data from the external node.
Specifically, the interface unit 11 includes an interface terminal 111 and a converter 112. The interface terminal 111 connects the external node and the designated port, and is configured to receive a request signal sent by the designated port, obtain a port address of the designated port and an external signal of the external node, and send the external signal to the converter 112. The converter 112 converts the received external signal of the external node into the original data that can be read by the switching unit 12, and then returns the original data to the interface terminal 111. This allows for the unified integration of the data formats in the security management switch for data exchange between the individual units.

The term security data is understood here to mean non-generic data which requires security checking and processing.
If the first exchange data is not secure data, the management unit 14 generates a first call signal. The switching unit 12 retrieves the first switching data from the storage unit 14 according to the first call signal and sends the first switching data to the interface unit 11. The interface unit 11 receives the first switching data, and transmits the first switching data to the designated port according to the port address of the designated port, thereby completing the data switching process.
If the first exchange data is security data, that is, if security check calculation and processing are required for the first exchange data, the management unit 14 generates a check signal, receives the first exchange data according to the check signal, and transmits the first exchange data to the security unit 15.
