Detailed description of the invention
The flow chart of the network message sending control method that Fig. 1 provides for the embodiment of the present invention, as it is shown in figure 1, the method includes:
Step 100, virtual switch obtains the message of virtual ip address that multiple network application sends, that carry described Microsoft Loopback Adapter by the Microsoft Loopback Adapter configured for multiple network applications, and wherein, Microsoft Loopback Adapter configures with network application one_to_one corresponding;
Corresponding Microsoft Loopback Adapter is distributed for each network application in physical machine, each Microsoft Loopback Adapter is provided with virtual protocol stack, that is, Microsoft Loopback Adapter and the configuration of network application one_to_one corresponding, it should be noted that be that the mode of the Microsoft Loopback Adapter of each network application one_to_one corresponding configuration is a lot of in the present embodiment, such as virtual switch adopts tun/tap driver to be Microsoft Loopback Adapter corresponding to each network application configuration, this partly belongs to prior art, repeats no more herein.
Physical machine needs carry out the mutual network application of information with opposite end message is sent initially to self in the Microsoft Loopback Adapter of corresponding configuration, the virtual ip address of Microsoft Loopback Adapter is added the position, packet header being enclosed in this message by virtual protocol stack, then the message carrying the virtual ip address of Microsoft Loopback Adapter is sent to virtual switch by Microsoft Loopback Adapter, when the message mutual with network side is sent to virtual switch by the Microsoft Loopback Adapter of configuration corresponding to self by multiple network applications, virtual switch will pass through the Microsoft Loopback Adapter pre-set and obtains what multiple network application sent, carry the message of the virtual ip address of Microsoft Loopback Adapter.
Step 101, the priority that the virtual ip address with each Microsoft Loopback Adapter that the virtual ip address inquiry entrained by the message that described virtual switch is applied according to described multiple network prestores is corresponding, it is determined that the priority of described multiple network application;
After virtual switch obtains message that multiple network application sends, that carry virtual ip address by Microsoft Loopback Adapter, the virtual ip address entrained by message according to multiple network application inquires about the priority that the virtual ip address with each Microsoft Loopback Adapter prestored is corresponding, so that it is determined that send the priority of the multiple network application of network application message.
Step 102, the message received is transmitted controlling by described virtual switch according to the priority of the flow control policy preset and the application of described multiple network.
Virtual switch is after determining the priority of the multiple network application sending network application message, the flow control policy that inquiry is preset, determines the message of priority treatment according to the priority that flow control policy and multiple network are applied and is sent to network side by physical network card. wherein, concrete flow control policy can need to be adjusted according to actual application, it is illustrated below: when default flow control policy is control successively according to order from high to low, the message of multiple network application is transmitted controlling successively by the priority that virtual switch is then applied according to the multiple network obtained according to order from high to low, namely the message of the high network application of priority is first sent, retransmit the message of the low network application of priority, or, when default flow control policy is to be pre-configured with the flow-control ratio corresponding with priority, the message of multiple network application is transmitted controlling by the priority that then virtual switch is applied according to multiple network according to the default flow-control ratio corresponding with priority simultaneously, such as, if preset flow control policy be respectively with the first priority, the second priority flow-control ratio corresponding with third priority is 3:2:1, wherein, first priority be superior to the second priority, second priority be superior to third priority, when the priority that virtual switch determines the network application sending message is the first priority and third priority, then control message according to the flow-control ratio of 3:1 to send.
The network message sending control method that the present embodiment provides, virtual switch by obtaining the message of virtual ip address that multiple network application sends, that carry Microsoft Loopback Adapter for the Microsoft Loopback Adapter of multiple network application correspondences configuration, the priority that the virtual ip address with each Microsoft Loopback Adapter prestored is corresponding is inquired about according to the virtual ip address that message carries, determine the priority that multiple network is applied, then be transmitted the message received controlling according to the priority of the flow control policy preset and multiple network application. It is achieved thereby that when offered load is heavier, ensures the message proper communication that priority is high, improve the efficiency of high-level business, when avoiding low priority traffic to uprush, affect the access of high-level business.
The flow chart of another network message sending control method that Fig. 2 provides for the embodiment of the present invention, as in figure 2 it is shown, the method includes:
Step 200, virtual switch obtains the message of virtual ip address that multiple network application sends, that carry described Microsoft Loopback Adapter by the Microsoft Loopback Adapter configured for multiple network applications, and wherein, Microsoft Loopback Adapter configures with network application one_to_one corresponding;
Corresponding Microsoft Loopback Adapter is distributed for each network application in physical machine, each Microsoft Loopback Adapter is provided with virtual protocol stack, that is, Microsoft Loopback Adapter and the configuration of network application one_to_one corresponding, it should be noted that be that the mode of the Microsoft Loopback Adapter of each network application one_to_one corresponding configuration is a lot of in the present embodiment, such as virtual switch adopts tun/tap driver to be Microsoft Loopback Adapter corresponding to each network application configuration, this partly belongs to prior art, repeats no more herein.
Physical machine needs carry out the mutual network application of information with opposite end message is sent initially to self in the Microsoft Loopback Adapter of corresponding configuration, the virtual ip address of Microsoft Loopback Adapter is added the position, packet header being enclosed in this message by virtual protocol stack, then the message carrying the virtual ip address of Microsoft Loopback Adapter is sent to virtual switch by Microsoft Loopback Adapter, when the message mutual with network side is sent to virtual switch by the Microsoft Loopback Adapter of configuration corresponding to self by multiple network applications, virtual switch will pass through the Microsoft Loopback Adapter pre-set and obtains what multiple network application sent, carry the message of the virtual ip address of Microsoft Loopback Adapter.
Step 201, the priority that the virtual ip address with each Microsoft Loopback Adapter that the virtual ip address inquiry entrained by the message that described virtual switch is applied according to described multiple network prestores is corresponding, it is determined that the priority of described multiple network application;
