Refer to accompanying drawing 5, be method for parameter configuration embodiment 4 flow chart of a kind of virtual network provided by the invention, the method specifically can comprise the following steps:

Step S501: based on the Actual path of information transmission between described first virtual machine and the second virtual machine, analyzes at least two physical machine comprised in the Actual path obtained between described first virtual machine and the second virtual machine;

Step S502: the physical machine network parameter of at least two physical machine described in acquisition;

Step S504: judge the numerical value of the numerical value of the default network parameter of described first virtual machine and the default network parameter of the second virtual machine whether be greater than described in the numerical value of default network parameter of at least two network interface cards, obtain the first comparison result;

Wherein, step S501-504 is consistent with the step S401-404 in embodiment 3, does not repeat in the present embodiment.

Step S505: the numerical value of the default network parameter of at least two network interface cards described in being greater than based on the first comparison result sign numerical value of default network parameter of described first virtual machine and the numerical value of the default network parameter of the second virtual machine, the function information of at least two network interface cards described in acquisition;

Wherein, described function information at least represents the whether supported data bag process of described network interface card.

At least one during the optimization process etc. that concrete, this data processing comprises packet fragmentation, wrap for TPC (turboproductcode, product code) processes packet.

Wherein, because network interface card connects the equipment between this physical machine and network, the function information of this network interface card also can think the function of this physical machine in this transmission of data packets.

In concrete enforcement, because the TSO (TCPSegmentOffload) in network interface card/LRO (LargeReceiveOffload) can represent the whether supported data bag process of this network interface card, therefore, can obtain the parameter of this TSO/LRO, to judge the whether supported data bag process of this network interface card based on this parameter.

Wherein, this TSO is a kind of a small amount of disposal ability utilizing network interface card, reduces the technology that CPU sends packet load.

Wherein, can realize by by multiple TCP (TransmissionControlProtocol based on this LRO, transmission control protocol/IP(Internet Protocol)) Data Integration is in one structure, and at the network protocol stack consigning to upper strata sometime as a large packet after a while, to reduce the expense of upper-layer protocol stack deal with data, improve the ability of system acceptance tcp data bag.

Step S506: according to described function information, the whether supported data bag process of at least two network interface cards described in analyzing respectively, obtains analysis result;

Wherein, the function information of this acquisition is analyzed, to determine its whether supported data bag process.

In concrete enforcement, represent the whether supported data bag process of this network interface card by giving different values for parameter in this network interface card, as 0 expression can be adopted not support, 1 expresses support for.

Wherein, to each network interface card in this first virtual machine and Actual path corresponding to the second virtual machine, whether the process of supported data bag is all analyzed respectively, judges whether equal supported data process, if all support to perform step S508, otherwise performs step S507.

Step S507: at least two network interface card not all supported data bag process described in characterizing based on described analysis result, the physical machine network parameter according to described physical machine obtains described virtual machine network parameter;

Wherein, when the not all supported data bag process of these at least two network interface cards, then in this first virtual machine and Actual path corresponding to the second virtual machine, arbitrary network interface card is the process of supported data bag not, when then needing to carry out data packet transmission between these two virtual machines, once the virtual machine network parameter of this virtual machine is greater than the physical machine network parameter of this physical machine, need to carry out burst and recombinate then may realizing to packet, the data packet transmission namely between these two virtual machines cannot realize; Or the process of a network interface card supported data bag, another is not supported, then the data packet transmission between these two virtual machines also cannot realize.

Therefore, need the physical machine network parameter analysis in conjunction with this physical machine to obtain this virtual machine network parameter, coordinate with this physical machine network parameter to make this virtual machine network parameter.

Wherein, the described physical machine network parameter according to described physical machine obtains described virtual machine network parameter, specifically comprise: according to the configuration information of pre-stored in described physical machine, analyze the type of the virtual channel obtaining described first virtual machine and the second virtual machine composition; Based on the type of described virtual channel, select the computation rule preset; Based on described default computation rule and described physical machine network parameter, calculate described virtual machine network parameter.

Concrete, the type of virtual channel between the virtual machine of its mounting and other virtual machines is stored in this physical machine, the type of this virtual channel can for user in advance manual configuration obtain, the type of this virtual channel can comprise based on GRE (GenericRoutingEncapsulation, generic route encapsulation) or the type such as tunnel based on VxLAN agreement.

In concrete enforcement, need in packet due to the transmission of virtual machine to add the information corresponding to this tunnel type in its packet header, be described for MTU, between the MTU of the MTU of packet that this virtual machine sends relative to physical machine, there is a data difference, this data difference size virtual channel type corresponding with this virtual machine is corresponding, and as based in the virtual network of GRE, this data difference value is 46, in virtual network based on VxLAN agreement, this data difference value is 50.Wherein, when the MTU of this physical machine is known, then based on the type of the virtual channel of the virtual machine of its correspondence, the MTU of the virtual machine of its correspondence can be calculated.

Step S508: at least two network interface card all supported data bag process described in characterizing based on described analysis result, the preset maximum value according to described virtual machine obtains described virtual machine network parameter.

Wherein, this preset maximum value characterizes the maximum data packet data volume of described virtual function transmission.

Wherein, each network interface card supported data bag process in this first virtual machine and Actual path corresponding to the second virtual machine, then this virtual machine can adopt the virtual machine network parameter of the physical machine network parameter being greater than this physical machine to carry out data packet transmission, the burst to packet and restructuring can be realized in this Actual path, therefore, can be higher value to the virtual machine network optimum configurations of this virtual machine, as the preset maximum value of this virtual machine.
