It should be noted that being for target appearance according to the process that the network resource information configures target container
The process of device Configuration network attribute (such as IP address, MAC Address), transmission property (such as data transfer mode) etc., configures
Cheng Hou, target container the corresponding Internet resources of the network resource information can be used to carry out data message transmission.
In addition, the container in the embodiment of the present invention in multiple calculate nodes distributes Internet resources by control node for it,
It that is to say, Internet resources used in the container in multiple calculate node are managed by control node, at this point, multiple meter
Each container in operator node will respectively possess individual Internet resources, thus the every two container in multiple calculate node it
Between can be directly in communication with each other by respective Internet resources.In the case, some calculating in multiple calculate node
When container in node is moved in other calculate nodes, which can be carried out logical without Internet resources used in change
Letter, to realize the persistence and migration of Internet resources used in container.
Furthermore control node can be accessed according to each container in multiple calculate node in the embodiment of the present invention
Network come for its distribute Internet resources so that in multiple calculate node access heterogeneous networks container be isolated,
And the container for accessing identical network is able to direct communication, and in the case where each container respectively possesses individual Internet resources,
Double layer intercommunication between the container of identical network is accessed, the MAC Address of each container is mutually visible.
Specifically, it when the virtual machine receives the network resource information of control node transmission, is configured for target container
The corresponding Internet resources of the network resource information；When the bridge configuration module receives the Internet resources letter of control node transmission
When breath, by network resource information storage into the bridge in the calculate node.
It should be noted that before the virtual machine configures the corresponding Internet resources of the network resource information for target container,
Target container can be first created in the virtual machine, and the virtual machine can match receiving the container for configuring target container
Before setting instruction, just target container is created in the virtual machine, alternatively, being somebody's turn to do for control node transmission can received
When network resource information, then in the virtual machine target container is created.
In addition, the virtual machine is that target container configures the corresponding Internet resources of the network resource information, it is to hold to target
The network attribute of device is configured, so that target container can be used the Internet resources and carry out data message transmission, and the bridge is matched
Module is set by network resource information storage into the bridge, is to be configured to the transmission property of target container, so that should
Bridge can be forwarded according to the data message that the network resource information generates target container.
Wherein, when which is that target container configures the network resource information corresponding Internet resources, can first judge
With the presence or absence of the target network interface for being connected to target network in the virtual machine；When there is no target network interfaces in the virtual machine
When, according to target network type, target network interface is created in the virtual machine；The virtual machine is connect with target network interface for father
Container joint of the mouth creation sub-interface as target container；The address of the container joint of target container is set mesh by the virtual machine
Mark address.
It should be noted that target network interface is the network interface for being connected to target network, it that is to say, container can lead to
Cross target network interface access target network.At this point, each network has a respective individual network interface, and the container of identical network
Identical network interface can be accessed, to be achieved the isolation between the container of heterogeneous networks, realizes the appearance of identical network
Double layer intercommunication between device.
It is by mesh in addition, being that father's interface creates sub-interface as the container joint of target container using target network interface
The container joint of mark network interface and target container is attached, at this point, target container is sent out by the container joint of target container
The data message sent will be transferred to target network interface.
Furthermore destination address is set by the address of the container joint of target container, is to set the address of target container
It is set to destination address, to be achieved the configuration to the network attribute of target container.
Wherein, which can in advance set the title of network interface to the net for the network that the network interface is connected
Network mark, at this point, when the virtual machine is judged in the virtual machine with the presence or absence of the target network interface for being connected to target network, it can be with
Judge the network interface that whether there is entitled target network identity in the virtual machine；If there are entitled mesh in the virtual machine
The network interface for marking network identity, then can determine that there are target network interfaces in the virtual machine；If do not deposited in the virtual machine
In the network interface of entitled target network identity, then it can determine that there is no target network interfaces in the virtual machine.
Wherein, which when creating target network interface in the virtual machine, can work as mesh according to target network type
Mark network type is vlan type, and when target network transmission is labeled as target vlan-label, creation is for connecting in the virtual machine
The network interface of vlan is connect, and it is target vlan-label that the vlan-label of corresponding subnet, which is arranged, in the network interface, obtains mesh
Mark network interface；When target network type is vxlan type, creates in the virtual machine and connect for connecting the network of vxlan
Mouthful, and using the network interface as target network interface.
It is in the virtual machine it should be noted that creating the network interface for connecting vlan in the virtual machine
Creation can encapsulate the network interface of vlan-label for the data message from container.And corresponding son is set in the network interface
The vlan-label of net is target vlan-label, is to set target vlan mark for the vlan-label that the network interface can encapsulate
Label, to obtain the target network interface for being connectable to target network.
In addition, being needed according to target vlan-label in the virtual machine due to when target network type is vlan type
Target network interface is created, and when target network type is vxlan type, it can be directly at this without target vxlan mark
Target network interface is created in virtual machine, therefore, when target network type is vlan type, it is virtual that control node is sent to this
Target network transmission label can be carried in the network resource information of machine, and when target network type is vxlan type, control
Node, which is sent in the network resource information of the virtual machine, can not carry target network transmission label.
Wherein, when which stores the network resource information into the bridge, target network class can be worked as
Type is vxlan type, when target network transmission is labeled as target vxlan mark, destination address is corresponding with target vxlan mark
It stores in the bridge.
It should be noted that destination address storage corresponding with target vxlan mark is arrived the bridge by the bridge configuration module
In, can make the bridge according to target xlan identify, to address be destination address target container generate data message into
Row forwarding, to be achieved the configuration to the transmission property of target container.
In practical application, the bridge is in the data message for receiving other calculate nodes transmission except the calculate node
When, it can also need to be stored with destination address and mesh in the bridge by the data-message transmission to target container, in the case
The corresponding relationship between vlan-label is marked, so that destination address can be destination address according to target xlan label by the bridge
Data-message transmission into target container.Thus, which stores the network resource information into the bridge
When, it can also be vlan type when target network type, when target network transmission is labeled as target vlan-label, by destination address
Storage corresponding with target vlan-label is into the bridge.
Further, the target container created in the virtual machine is carried out according to the network resource information in step 405
After configuration, target container can be sent the data message of generation.And work as the target network that target container is accessed
When network type difference, the mode that target container sends datagram is also different, is specifically divided into the progress of the following two kinds situation
Explanation.
The first situation: when the network type of the target network of target container access is vlan type, target container is raw
At the first data message forwarding go out the process of the calculate node and may include steps of (1)-(3).
(1) when target container receives the first transmission instruction, the first data message of generation is passed through into target container
Container joint is transferred to target network interface.
It should be noted that the first transmission instruction is used to indicate and sends to the first data message of generation, and first
Sending instruction can be triggered by user, or can be by the calculate node automatic trigger.When the first transmission instruction is touched by user
When hair, user can be clicking operation, slide, voice behaviour by the second specified operation triggering, the second specified operation
Make etc..
In addition, due to target container container joint with target network interface be father's interface, target container will generate
The first data message sent by the container joint of target container after can be directly by the first data-message transmission to target network
Network interface.
(2) when target network interface receives the first data message of target container transmission, generation carries the first number
The bridge is transferred to according to the first encapsulated message of message and target vlan-label, and by the first encapsulated message.
It should be noted that being distinguished for the ease of the subsequent bridge to the data message from vlan or vxlan, mesh
Mark network interface can be used target vlan-label and be packaged to the first data message, be transmitted with obtaining the first encapsulated message
Give the bridge.
In addition, target network interface generates the first encapsulated message for carrying the first data message and target vlan-label
When, target vlan-label can be used, the first data message is packaged, with the additional object vlan in the first data message
Label obtains the first encapsulated message.
Furthermore when the first encapsulated message is transferred to the bridge by target network interface, the virtual of the virtual machine can be passed through
First encapsulated message is transferred to the bridge by network interface card.
(3) when the bridge receives the first encapsulated message of target network interface transmission, the first encapsulated message is carried out
Forwarding.
It should be noted that after the bridge receives the first encapsulated message, can first judge in the first encapsulated message whether
Vlan-label is carried, if carrying vlan-label, can determine the first encapsulated message from vlan, at this point, the bridge
First encapsulated message can not be operated, directly the first encapsulated message is forwarded.
In addition, when the bridge is forwarded the first encapsulated message, it can be by the physical network card of the calculate node to
One encapsulated message is forwarded.
Further, after which is forwarded the first encapsulated message, other calculate nodes can be encapsulated to first
Message is received, specifically, when the bridge in other calculate nodes receives the first encapsulated message of calculate node transmission
When, the first encapsulated message is transferred to the first encapsulated message to be sent out by the vlan-label that can be carried according to the first encapsulated message
Past network interface；When the network interface receives the first encapsulated message, the first number can be obtained from the first encapsulated message
According to message, and according to the destination address of the first data message by the first data-message transmission to corresponding container.
Wherein, the vlan-label that the bridge in other calculate nodes is carried according to the first encapsulated message reports the first encapsulation
When text is transferred to the first encapsulated message network interface to be sent to, the vlan-label that can be carried according to the first encapsulated message is true
Determine purpose virtual machine, and the first encapsulated message is transferred to purpose virtual machine；When purpose virtual machine receives the first encapsulated message
When, the first encapsulated message network interface to be sent to can be determined according to the vlan-label that the first encapsulated message carries, and will
First encapsulated message is transferred to the network interface.
Wherein, it can be previously stored in the bridge in other calculate nodes corresponding between vlan-label and capsule address
Relationship, at this point, when the bridge in other calculate nodes determines purpose virtual machine according to the vlan-label that the first encapsulated message carries,
The capsule address of available storage corresponding with the vlan-label of the first encapsulated message carrying, and be acquired container by address
Virtual machine where the container of address determines to be purpose virtual machine.
Wherein, purpose virtual machine determines that the first encapsulated message to be sent to according to the vlan-label that the first encapsulated message carries
Network interface when, can will can encapsulate the vlan-label that first encapsulated message carries in purpose virtual machine for data message
Network interface is determined as the first encapsulated message network interface to be sent to.
It wherein, can when the network interface in other calculate nodes obtains the first data message from the first encapsulated message
To decapsulate to the first encapsulated message, to remove the vlan-label entrained by it from the first encapsulated message, first is obtained
Data message.
Second situation: when the network type of the target network of target container access is vxlan type, target container is raw
At the second data message forwarding go out the process of the calculate node and may include steps of (4)-(6).
(4) when target container receives the second transmission instruction, the second data message of generation is passed through into target container
Container joint is transferred to target network interface.
It should be noted that the second transmission instruction is used to indicate and sends to the second data message of generation, and second
Sending instruction can be triggered by user, or can be by the calculate node automatic trigger.When the second transmission instruction is touched by user
When hair, user can be clicking operation, slide, voice behaviour by the specified operation triggering of third, the specified operation of third
Make etc..
In addition, due to target container container joint with target network interface be father's interface, target container will generate
The second data message sent by the container joint of target container after can be directly by the second data-message transmission to target network
Network interface.
(5) when target network interface receives the second data message of target container transmission, the second data message is passed
It is defeated to arrive the bridge.
It should be noted that target network interface by the second data-message transmission to the bridge when, can be virtual by this
The Microsoft Loopback Adapter of machine is by the second data-message transmission to the bridge.
(6) when the bridge receives the second data message of target network interface transmission, generation carries the second data
Second encapsulated message of message and target vxlan mark, and the second encapsulated message is forwarded.
It should be noted that can first judge whether the second data message is taken after the bridge receives the second data message
With vlan-label, if not carrying vlan-label, the second data message can be determined from vxlan, at this point, the bridge
Can source address (i.e. destination address) based on the second data message obtain target vxlan mark, and generate and carry the second number
According to the second encapsulated message that message and target vxlan are identified, the second encapsulated message is forwarded.
In addition, due to the corresponding relationship being previously stored in the bridge between destination address and target vxlan mark, because
This, after which receives the second data message, can obtain directly according to the source address (i.e. destination address) of the second data message
The target vxlan of storage corresponding with the source address is taken to identify.
It, can be by the physical network card of the calculate node to furthermore when the bridge is forwarded the second encapsulated message
Two encapsulated messages are forwarded.
Further, after which is forwarded the second encapsulated message, other calculate nodes can be encapsulated to second
Message is received, specifically, when the bridge in other calculate nodes receives the second encapsulated message of calculate node transmission
When, the second data message can be obtained from the second encapsulated message, and identify according to the vxlan that the second encapsulated message carries, it will
Second data-message transmission to the second encapsulated message network interface to be sent to；When the network interface receives the data message
When, it can be according to the destination address of the data message by the data-message transmission to corresponding container.
It wherein, can be to when the bridge in other calculate nodes obtains the second data message from the second encapsulated message
Two encapsulated messages are decapsulated, and to remove the vxlan mark entrained by it from the second encapsulated message, obtain the second datagram
Text.
Wherein, the bridge in other calculate nodes is identified according to the vxlan that the second encapsulated message carries, by the second datagram
When text is transferred to the second encapsulated message network interface to be sent to, the vxlan that can be carried according to the second encapsulated message is identified
Determine purpose virtual machine, and by the second data-message transmission to purpose virtual machine；When purpose virtual machine receives the second datagram
Wen Shi, can determine the second data message network interface to be sent to according to the destination address of the second data message, and by
Two data-message transmissions are to the network interface.
Wherein, pair that can be previously stored in the bridge in other calculate nodes between vxlan mark and capsule address
It should be related to, at this point, the bridge in other calculate nodes is identified according to the vxlan that the second encapsulated message carries determines purpose virtual machine
When, the capsule address of available storage corresponding with the vxlan mark of the second encapsulated message carrying, and be acquired by address
Virtual machine where the container of capsule address determines to be purpose virtual machine.
Wherein, purpose virtual machine determines the second data message net to be sent to according to the destination address of the second data message
It, can be by address is connected by the container of the destination address of the second data message in purpose virtual machine network interface when network interface
It is determined as the second data message network interface to be sent to.
Further, the encapsulated message which can also send other calculate nodes receives, and the meter
Operator node carries out received operation with above-mentioned other calculate nodes to the calculating section to the encapsulated message that other calculate nodes are sent
It is similar that the first encapsulated message or the second encapsulated message that point is sent carry out received operation.
It that is to say, when the bridge in the calculate node receives the envelope of the transmission of other calculate nodes except the calculate node
When filling message, if carrying vlan-label in the encapsulated message, the encapsulated message can be transferred to according to the vlan-label
The encapsulated message purpose network interface to be sent to, when purpose network interface receives the encapsulated message, from the encapsulation report
Data message is obtained in text, according to the destination address of the data message by the data-message transmission to corresponding container；If should
Vxlan mark is carried in encapsulated message, then data message can be obtained from the encapsulated message, and identify according to the vxlan, it will
The data-message transmission is to the encapsulated message purpose network interface to be sent to, when purpose network interface receives the datagram
Wen Shi, according to the destination address of the data message by the data-message transmission to corresponding container.
