Embodiment 1
[0051] Embodiment 1, a flow control method of address resolution protocol message, such as figure 1 shown, including:
[0052] S101. Capture the ARP outbound packets sent from the virtual machine to the physical machine;
[0053] S102. Put the captured ARP outgoing packet in the queue corresponding to the virtual machine that sends the ARP outgoing packet;
[0054] S103. Polling each queue in turn, and each time a queue is polled, a token is taken out from the token bucket, and an ARP outbound packet is taken out from the polled queue for outbound processing.
[0055] Since each virtual machine on the physical machine node shares the network card device of the physical machine, that is to say, there is a problem of network resource preemption between virtual machines and between virtual machines and physical machines. Considering that the packet sending by the physical machine can be controlled in the data center, in this embodiment, the ARP outgoing packets of the physical ...
Embodiment 2
[0080] Embodiment 2, a flow control device for address resolution protocol messages, such as image 3 shown, including:
[0081] A message capture module 31, configured to capture the ARP outbound message sent from the virtual machine to the physical machine;
[0082] The allocation module 32 is configured to place the captured ARP outbound message in the queue S corresponding to the virtual machine that sends the ARP outbound message;
[0083] Packet-out control module 33, used to poll each queue S in turn, when each polling queue S, take out a token from the token bucket TB, take out an ARP packet-out message from the polled queue S Carry out package processing.
[0084] In an alternative solution of this embodiment, the allocation module 32 places the captured ARP outbound message in the queue corresponding to the virtual machine that sends the ARP outbound message, which may specifically refer to:
[0085] The distribution module 32 resolves the IP address of the virtua...
