According to the intermediate MAC Address that the clear text received carries, the clear text is forwarded by step S201 Business logic processing is performed to the corresponding virtual switch of the intermediate MAC Address.

The message processing method based on SR-IOV, is realized based on the interchanger disposed on physical network card, and with The method for following virtual switch processing messages based on SR-IOV that the application provides is engaged, by being disposed on hardware network interface card Interchanger data message forwarding ability, with reference to ARP (Address Resolution Protocol, address resolution protocol) Agency, the data traffic that virtual machine is led directly to physical network card drain into fictitious host computer level in virtual environment, i.e.,：By virtual machine The data traffic to send datagram to physical network drains into the virtual machine interchanger disposed in virtual environment on fictitious host computer In and data traffic that physical network sends datagram to virtual machine, drain into fictitious host computer top in virtual environment In the virtual machine interchanger of administration, the complete business of data message progress that can come in the virtual switch for drainage is patrolled Processing is collected, so as to avoid the problem that physical switches function is single, the business function for making data traffic is more diversified.

Clear text described in the embodiment of the present application refers to that the virtual machine or the physical network send and not yet exist The data message of business logic processing is carried out on the virtual switch.Data message is the data for exchanging and transmitting among network Block, data message can constantly be packaged into the various forms such as grouping, bag, frame in transmission process and be transmitted, data message Packaged type is exactly to add some message segments, for example, addition message segment in comprising type of message, message version, message length, The data messages such as message entity.

For the clear text sent from the virtual machine to the physical network and from the physical network to institute The clear text of virtual machine transmission is stated, is described in detail one by one below.

1st, the clear text sent from the virtual machine to the physical network.

If the clear text is sent from the virtual machine to the physical network, the clear text It is received by the corresponding virtual functions module of the preconfigured virtual machine, and passes through the preconfigured virtual switch Corresponding virtual functions module forwards are to the virtual switch, and in the present embodiment, the physical function module is used to implement object Manage function (Physical Function, PF), PF as shown in Figure 3；The virtual functions module is used to implement virtual work( It can VF0, VF1, the VF2VFn of (Virtual Function, VF) as shown in Figure 3.

For example, as shown in Figure 3, VM1 (virtual machine) sends clear text and gives LAN (physical network), then passes through VM1 pairs The VF1 answered receives clear text, and passes through vSwitch (Virtual Switch, void in L2Switch (Layer 2 switch) Intending interchanger) corresponding VF0 is sent to vSwitch.

If it is well known that the virtual machine sends clear text to the network, the virtual machine can be examined first ARP (Address Resolution Protocol, the address resolution protocol) cache table of oneself is looked into, checks and wherein whether there is The IP address of the network and the mapping relations of MAC Address；If it is present by the MAC Address of network MAC as a purpose Address is encapsulated in the clear text；If it does not exist, then the virtual machine can send an ARP request, the ARP please The target ip address asked is the IP address of the network, and destination-mac address is the broadcast frame of MAC Address, and source IP address is described The IP address of virtual machine, source MAC are the MAC Address of the virtual machine.After interchanger receives the ARP request, hair The existing ARP request is broadcast frame, then sends the ARP request to all ports of interchanger.

In the present embodiment, in order to realize the data traffic that the virtual machine is sent to clear text to the physical network It drains into the virtual machine interchanger disposed in virtual environment on fictitious host computer, Host in virtual environment as shown in Figure 3 The vSwitch disposed on (fictitious host computer), otherwise varied with the transmission processing procedure of above-mentioned ARP request, the ARP request is specific It is handled using the mode of being implemented as described below：

1) ARP request of the virtual machine transmission is received by the corresponding virtual functions module of the virtual machine；

2) ARP request is broadcasted to all virtual functions modules；

3) virtual switch is received by the corresponding virtual functions module of the virtual switch and sends arp response, Using the MAC Address that the arp response carries as the intermediate MAC Address.

Therefore, intermediate MAC Address refers to the corresponding MAC Address of virtual switch described in the present embodiment.

For example, as shown in Figure 3, VM1 sends clear text to LAN, then first checks for the arp cache table of itself, The correspondence there are the IP address of LAN and MAC Address is wherein searched whether, if it does not exist, then by VF1 to L2Switch Send ARP request；After L2Switch receives ARP request, to VF0, VF2VFn broadcast ARP request (in order to count The vSwitch disposed on Host in virtual environment (fictitious host computer) is drained into according to flow, forbids physics end corresponding to LAN herein Mouth sends ARP request)；VSwitch receives the ARP request of L2Switch broadcast by VF0, after receiving ARP request, creates The corresponding arp response of ARP request, and by itself corresponding MAC Address (the corresponding MAC Address of vSwitch) EE:FF:FF:FF: FF:FF is encapsulated in arp response, and arp response is sent to L2Switch by VF0；L2Switch receives vSwitch by VF0 After the arp response of return, by MAC Address wherein included (the corresponding MAC Address of vSwitch) EE:FF:FF:FF:FF:FF As intermediate MAC Address (i.e. the target MAC (Media Access Control) address of virtual machine transmission clear text), based on this, the pending report of VM1 transmissions Text is drained in the vSwitch that is disposed in virtual environment on Host；If it is present show that warp-wise LAN has been transmitted across before this Data message, there are the IP address of LAN and the correspondence of MAC Address in the arp cache table of VM1, i.e.,：xxx.xxx.x.x- EE:FF:FF:FF:FF:FF, directly by EE:FF:FF:FF:FF:FF is as intermediate MAC Address, and based on this, what VM1 was sent waits to locate Reason message is drained in the vSwitch that is disposed in virtual environment on Host.

Similar, the data traffic that all virtual machines can be sent to clear text to the physical network all drains In the virtual switch disposed into virtual environment on fictitious host computer.

In the specific implementation, interchanger maintenance has the mapping relations of MAC Address and port, therefore by the intermediate MAC The correspondence of location virtual functions module corresponding with the virtual switch, the mapping for adding in the MAC Address and port are closed In system.

In addition, in the specific implementation, in order to realize the Network Isolation between the virtual machine, promote the safety of virtual machine Property, corresponding label can be respectively arranged with for each virtual machine, for example, for VF0, VF1, VF2VFn points Corresponding virtual local area network tags (VLAN Tag) are not set, and the virtual local area network tags of each virtual machine do not repeat mutually, One-to-one virtual machine can determine according to VLAN Tag.

Based on this, interchanger can also safeguard void in addition to needing to safeguard the mapping relations of the MAC Address and port The mapping relations of plan machine and label.Specifically, can by the mapping relations and the virtual machine of the MAC Address and port with The mapping relations of label are safeguarded in respective table respectively；In addition, due between the virtual machine and the port Mapping relations be fixed, and hence it is also possible to establish the virtual machine or the port, the MAC Address and the mark Sign three between mapping relations, safeguarded in a table MAC Address and port mapping relations and the virtual machine with The mapping relations of label.

Correspondingly, the virtual switch is also required to safeguard the mapping relations of the virtual machine and label, the otherwise void The label of the data message encapsulation can not be contacted by intending interchanger.For example interchanger is broadcasted to all virtual functions modules Before the ARP request, the Tag Packaging of virtual machine of the ARP request will be sent among the ARP request；When the void After plan interchanger receives the ARP request, according to the virtual machine of self maintained and the mapping relations of label, institute is released State the corresponding label of virtual machine of the transmission ARP request of ARP request encapsulation.

In addition, the clear text is forwarded to the corresponding virtual switch of the intermediate MAC Address by this step During performing business logic processing, the Tag Packaging that the clear text can also be corresponded to virtual machine is waited to locate described It manages among message, the clear text is sent to after the virtual switch, can be safeguarded according to the virtual switch The mapping relations of the virtual machine and label release the corresponding label of the virtual machine of the clear text outer envelope.

2nd, the clear text sent from the physical network to the virtual machine.

3) virtual switch is received by the corresponding virtual functions module of the virtual switch and sends arp response, Using the MAC Address that the arp response carries as the intermediate MAC Address.

For example, as shown in Figure 3, LAN sends clear text to VM2, then first checks for the arp cache table of itself, The correspondence there are the IP address of VM2 and MAC Address is wherein searched whether, if it does not exist, then passing through the corresponding physics of LAN Network interface sends ARP request to L2Switch；After L2Switch receives ARP request, to VF0, VF2VFn broadcast arp Request；VSwitch receives the ARP request of L2Switch broadcast by VF0, after receiving ARP request, creates ARP request pair The arp response answered, and by itself corresponding MAC Address EE:FF:FF:FF:FF:FF is encapsulated in arp response, by VF0 to L2Switch sends arp response；It, will be wherein included after L2Switch receives the arp response that vSwitch is returned by VF0 MAC Address EE:FF:FF:FF:FF:FF is as intermediate MAC Address, and based on this, the clear text that LAN is sent is drained to void In the vSwitch disposed in near-ring border on Host；If it is present show that warp-wise VM2 has been transmitted across data message, LAN before this Arp cache table in there are the IP address of VM2 and the correspondence of MAC Address, i.e.,：xxx.xxx.x.x-EE:FF:FF:FF: FF:FF, directly by EE:FF:FF:FF:FF:FF is as intermediate MAC Address, and based on this, the clear text that LAN is sent is drained In the vSwitch disposed into virtual environment on Host.

Similar, the data traffic that the physical network can be sent to clear text to all virtual machines all drains In the virtual switch disposed into virtual environment on fictitious host computer.

In the specific implementation, interchanger maintenance has the mapping relations of MAC Address and port, therefore by the intermediate MAC The mapping relations of location virtual functions module corresponding with the virtual switch, the mapping for adding in the MAC Address and port are closed In system.

In this step, according to the intermediate MAC Address that the clear text received carries, by the clear text It is forwarded to the corresponding virtual switch of the intermediate MAC Address and performs business logic processing.

Step S202 is obtained after receive that the virtual switch sends perform business logic processing to the clear text The data message obtained.
