Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a broadcast message processing method according to an embodiment of the present disclosure.
The broadcast message processing method provided by the embodiment of the application is applied to a virtual switch, and can comprise the following steps:
step S101: and acquiring a broadcast message to be processed.
In practical application, the virtual switch may obtain the broadcast message to be processed first, and the number of the broadcast messages in the broadcast message to be processed may be determined according to actual needs.
Step S102: and matching the broadcast message to be processed with the ARP broadcast flow meter to obtain a matched broadcast message.
In practical application, after the broadcast message to be processed is obtained, the broadcast message to be processed may be matched with an Address Resolution Protocol (ARP) broadcast flow table, and the broadcast message to be processed is first screened by the ARP broadcast flow table, so as to reduce the number of matching broadcast messages for subsequent processing.
Step S103: judging whether the performance occupied by the matched broadcast message exceeds the requirement of a speed limit flow table or not; if the performance occupied by the matched broadcast message exceeds the requirement of the speed limit flow table, executing the step S104; if the performance occupied by the matched broadcast message does not exceed the requirement of the speed limit flow table, step S105 is executed.
Step S104: and discarding the broadcast message in the matched broadcast message according to the requirement of the speed-limiting flow table to obtain a target broadcast message, and executing the step S106.
Step S105: and step S106 is executed by taking the matched broadcast message as a target broadcast message.
Step S106: and sending the target broadcast message to a virtual machine connected with the virtual switch for processing.
In practical application, after the broadcast message to be processed is matched with the ARP broadcast flow meter to obtain a matched broadcast message, although the first reduction is performed on the broadcast message to be processed by using the ARP broadcast flow meter, the number of the matched broadcast messages may still be large, and at this time, it is necessary to judge whether the performance occupied by the matched broadcast message exceeds the requirement of the speed limit flow meter; if the performance occupied by the matched broadcast message exceeds the requirement of the speed limit flow table, discarding the broadcast message in the matched broadcast message according to the requirement of the speed limit flow table to obtain a target broadcast message; if the performance occupied by the matched broadcast message does not exceed the requirement of the speed limit flow table, taking the matched broadcast message as a target broadcast message; therefore, if the target broadcast message is subsequently sent to a virtual machine connected with the virtual switch for processing, the consumption of the broadcast message on the network resources of the virtual machine can be reduced, and further the virtual machine can have more network resources to process other data.
It should be noted that the type of the speed limit requirement in the speed limit flow table may be determined according to actual needs, for example, the type may be the processing quantity of the broadcast packet, the processing rate of the broadcast packet, and the like.
The application provides a broadcast message processing method, which is applied to a virtual switch and used for acquiring a broadcast message to be processed; matching the broadcast message to be processed with an ARP broadcast flow meter to obtain a matched broadcast message; judging whether the performance occupied by the matched broadcast message exceeds the requirement of a speed limit flow table or not; if the performance occupied by the matched broadcast message exceeds the requirement of the speed limit flow table, discarding the broadcast message in the matched broadcast message according to the requirement of the speed limit flow table to obtain a target broadcast message; and sending the target broadcast message to a virtual machine connected with the virtual switch for processing. In the application, the virtual switch does not directly send all broadcast messages to the virtual machine, but needs to use the ARP broadcast flow table and the speed-limit flow table to screen the broadcast messages to be processed, so that the performance occupied by the target broadcast messages meets the requirement of the speed-limit flow table, excessive performance resources occupied by the broadcast messages are avoided, and the network traffic forwarding efficiency of the virtual machine can be ensured.
In the broadcast message processing method provided by the embodiment of the application, before the virtual switch acquires the broadcast message to be processed, the virtual switch can also receive an ARP broadcast flow meter and a speed-limiting flow meter which are sent by a virtualization platform connected with the virtual switch; when the virtualization platform judges that the broadcast message flow of the virtual switch exceeds a preset threshold value, the virtualization platform sends an ARP broadcast flow meter and a speed-limiting flow meter.
That is, in practical application, the virtualization platform can control the broadcast message flowing through the virtual switch, so that when the virtualization platform determines that the broadcast message flow of the virtual switch exceeds a preset threshold value, the virtualization platform can send the ARP broadcast flow meter and the speed-limit flow meter to the virtual switch. In a specific application scenario, a preset threshold value can be set to 80% of the network performance of the virtual switch,
in practical application, after the virtual switch sends the target broadcast message to a virtual machine connected with the virtual switch for processing, whether a deletion instruction sent by a virtualization platform is received can be judged; if a deletion instruction is received, deleting the ARP broadcast flow table and the speed limit flow table; and when the virtualization platform judges that the broadcast message flow of the virtual switch does not exceed a preset threshold value, sending a deletion instruction.
That is, after the virtualization platform determines that the broadcast message flow of the virtual switch does not exceed the preset threshold, the virtualization platform may send a corresponding deletion instruction to the virtual switch, and after receiving the deletion instruction, the virtual switch may delete the ARP broadcast flow table and the rate-limiting flow table.
In the broadcast message processing method provided by the embodiment of the application, the virtual switch discards broadcast messages in the matched broadcast messages according to the requirements of the speed limit flow table, and determines the target number of the broadcast messages to be discarded based on the occupied performance of the matched broadcast messages and the requirements of the speed limit flow table in the process of taking the remaining matched broadcast messages as target broadcast messages; and randomly selecting the broadcast messages with the target quantity from the matched broadcast messages, discarding the broadcast messages, and taking the rest matched broadcast messages as target broadcast messages. Of course, the target number of broadcast messages may be selected to be discarded from the head of the matched broadcast message, or the target number of broadcast messages may be selected to be discarded from the tail of the matched broadcast message, and the like, which is not specifically limited herein.
In the broadcast message processing method provided by the embodiment of the application, after the virtual switch discards the broadcast message in the matched broadcast message, the virtual switch can also record the information of the discarded broadcast message and send the information to the sending end of the discarded broadcast message. So that the transmitting end can rapidly retransmit the discarded broadcast message based on the information of the discarded broadcast message.
The broadcast message processing method provided by the embodiment of the application is applied to a virtualization platform and can comprise the following steps:
judging whether the broadcast message flow of the virtual switch exceeds a preset threshold value or not;
if the broadcast message flow of the virtual switch exceeds a threshold value, an ARP broadcast flow meter and a speed limit flow meter are sent to the virtual switch;
the virtual switch receives the ARP broadcast flow meter and the speed-limiting flow meter and then acquires a broadcast message to be processed; matching the broadcast message to be processed with an ARP broadcast flow meter to obtain a matched broadcast message; judging whether the performance occupied by the matched broadcast message exceeds the requirement of a speed limit flow table or not; if the performance occupied by the matched broadcast message exceeds the requirement of the speed limit flow table, discarding the broadcast message in the matched broadcast message according to the requirement of the speed limit flow table to obtain a target broadcast message; and sending the target broadcast message to a virtual machine connected with the virtual switch for processing.
