Piece is for handling message transmitted by the port.
In one example, the configuration information of the port isolation group after division can be stored in the network equipment 11 itself
On chip 111, which can not support virtualization technology.
Under normal conditions, which can be used for handling message transmitted by the port of virtual system, for example, virtually
When the port 1 of system 112 sends message to port 2, which can be forwarded by chip 111.
Step S304: it when the port sends message, according to the configuration information of the port isolation group of preservation, determines
Group is isolated by whether the next-hop port being sent to belongs to same port with the message in the port for sending the message, if so,
S305 is thened follow the steps, otherwise, executes step S306.
In one example, it is assumed that when port 1 sends message, which can be virtual system 112 itself
Built-in message, be also possible to the message that other network equipments are sent to the network equipment 11, no matter which kind of message the message is, by
It will be sent by port 1 in the message, and in the application, for convenience, port 1 can be known as sending the end of the message
Mouthful.
Later, the network equipment 11 can be by the configuration information of the port isolation group saved on chip 111, and determining should
The next-hop port that message will be sent to, such as port 2, with the port 1 for sending the message, if belong to same port isolation
Group.
Step S305: the message is directly sent to the next-hop port from the port for sending message, is terminated
Process.
In the present embodiment, seen from the above description, the configuration information of port isolation group can be stored on chip, and should
Chip usually can be used for message transmitted by processing end mouthful.It is opposite to the processing speed of message since chip is hardware
It, can more faster, so that the method for realizing virtual system by applying this embodiment, the void divided for software
Quasi- system, handles the more efficient of message.
Step S306: the message is sent to the next-hop port from the port for sending message by refusal.
For example, it is assumed that message transmitted by the port 1 of virtual system 112 is broadcasting packet, since port 3 and port 4 are equal
Not with port 1 in the same port isolation group, then the broadcasting packet will not be sent to port 3 from port 1 by the network equipment 11
With port 4.Information to realize between virtual system 112 and virtual system 113 is isolated；And avoid the occurrence of virtual system
After 113 receive the broadcasting packet of virtual system 112, received broadcasting packet is still handled, the CPU of the network equipment 11 is caused
The wasting of resources.
Using the method for the present embodiment, by the way that the port for belonging to same virtual system is divided into same port isolation group
In, and the configuration information of the port isolation group after dividing is saved, it realizes in the net for not having the chip for supporting virtualization technology
Also the port between virtual system that virtual system may be implemented in network equipment, also, realized cannot communicate with each other, thus
The information isolation between virtual system is realized, has effectively ensured the communication security between virtual system, and due to this method
