It can be assumed that there are 2 VLAN-if interfaces on the forwarding board: VLAN-if1 and VLAN-if2, where a VLAN-TAG of a VLAN where VLAN-if1 is located is VLAN-TAG1, and a VLAN-TAG of a VLAN where VLAN-if2 is VLAN-TAG2, it may be assumed that VLAN-if1 is divided into first virtual devices, and the first virtual devices may include VLAN-TAG1, and if a transparent transport board on the distributed network device may process a message carrying VLAN-TAG1, a VLAN-TAG1 of the transparent transport board may be divided into the first virtual devices.
in the invention, after the service board of the distributed network equipment receives the message, the target virtual equipment to which the message belongs can be determined.
Specifically, it may be determined whether the packet carries a target identifier corresponding to the target virtual device, and if so, the target virtual device to which the packet belongs may be determined based on the target identifier; if not, the target virtual device to which the packet belongs may be determined based on the VLAN-if interface or the VLAN identifier carried by the packet.
The target identifier can be set by a user through self-definition, the name, the content and the like of the target identifier are not limited by the invention, and the target virtual equipment to which the message belongs can be identified theoretically, for example, the target virtual equipment can be Chinese characters, numerical values, letters and the like, and can be positioned on an extension part of the message.
in an embodiment shown in the present invention, it may be assumed that the packet carries a target identifier, and the target identifier is B, and after receiving the packet, the service board of the distributed device may analyze the packet, determine that the packet carries the target identifier, and then determine, based on the target identifier, that a target virtual device to which the packet belongs is a virtual device B.
in another embodiment shown in the present invention, it may be assumed that the message does not carry a target identifier, and after receiving the message, the service board of the distributed device may parse the message and determine that the message does not carry the target identifier, and then the service board may determine, based on a VLAN-if interface VLAN-if2 or a VLAN identifier VLAN-TAG2 carried by the message, that the target virtual device to which the message belongs is a virtual device B.
it should be noted that, after determining the target virtual device to which the packet belongs based on the VLAN-if interface or the VLAN identifier carried in the packet, the target identifier corresponding to the target virtual device may be added to the packet.
In the above embodiment, the service board may add a target identifier B corresponding to the virtual device B to the message.
Step 102: and processing the message based on a processing strategy preset in the local by the target virtual equipment.

In another embodiment shown, it may be assumed that the IPS board of the distributed network device receives the message C belonging to the target virtual device C, and the IPS board may first determine that the virtual device in the message C is the virtual device C, then search for a processing policy preset locally by the virtual device C, and if the search fails, the virtual device C may not process the message C. It can be assumed that the virtual device C includes VLAN-TAG3, and the IPS board cannot process the packet carrying VLAN-TAG3, and at this time, the IPS board may not process the packet.
step 103: and sending the message to a next service board so that the next service board further processes the message based on a processing strategy preset by the target virtual equipment on the next service board.
In the present invention, if the current service board processes the message based on the processing policy preset locally by the target virtual device, the message may be sent to the next service board after the message is processed, so that the next service board further processes the message based on the processing policy preset by the target virtual device on the next service board.
if the current service board does not find the processing strategy preset locally by the target virtual device, the message is not processed, and then the message is sent to the next service board, so that the next service board further processes the message based on the processing strategy preset by the target virtual device on the next service board.
In the present invention, after receiving a message, a service board on a distributed network device may determine a target virtual device to which the message belongs, and then process the message based on a processing policy preset locally by the target virtual device, and the service board may send the message to a next service board, so that the next service board may further process the message based on the processing policy preset by the target virtual device on the next service board.
