Specific embodiment
The purpose of the application is to provide a kind of data communications method, device, electronic equipment and computer readable storage medium,
Router applied to the support EVPN being created that using virtualization technology, it is desirable to provide a kind of to be answered by virtual router in generation
The mode of ARP request avoids for ARP being broadcast to adverse effect caused by all virtual machines.
To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application
In attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is
Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art
All other embodiment obtained without making creative work, shall fall in the protection scope of this application.
Embodiment one
Referring to Figure 1, Fig. 1 is a kind of flow chart of data communications method provided by the embodiments of the present application comprising following
Step, the executing subjects of following steps are virtual router, the virtual router be created that using virtualization technology come
The router for supporting EVPN, relies on certain hardware resource to establish:
S101: the ARP request that the first virtual machine is sent is received；
Current virtual router receives the ARP request sent by self-administered first virtual machine.
The ARP request be the first virtual machine needs communicated and generated and issued with another virtual machine because
To carry out communicating with another virtual machine must it is to be understood that another virtual machine mailing address, but due on each virtual machine not
It is stored with the mailing address of other virtual machines, therefore an important step is exactly the mailing address for first getting target virtual machine.
Traditional approach is broadcast in network by the way of all devices using by the ARP request, is asked to receive the ARP
The mailing address of itself is back to ARP request after confirmation has equipment needs to be communicated with itself by the target device asked
Issue equipment.But under virtualized network environment, virtual machine is instead of original entity device, and quantity is not by entity device
Limitation, not only scale is big and complicated for this network, and traditional broadcast mode not only results in the waste of bandwidth, also can be with virtual
Machine quantity increases the amount shipped out sharp increase for leading to ARP request, causes large effect to normal business.
For this problem, the application provides a kind of method for answering ARP request using virtual router come generation, i.e., virtual road
It first passes through study in advance by device and establishes the routing table of each virtual machine that it is managed, record has each virtual machine and every in the routing table
Corresponding relationship between a mailing address.That is the routing table is generated by being located at the virtual router on each virtual machine upper layer,
Whenever have virtual machine it needs to be determined that target virtual machine mailing address when, all only need to send corresponding ARP request to virtual road
By device, so that it may substitute the operation that target virtual machine makes feedback communication address, therefore this mistake by the virtual router
Journey be referred to alternatively as generation answer.For the virtual machine for issuing ARP request, do not need ARP being broadcast to each other virtual machine,
It only needs to be sent to virtual router；For target virtual machine, eliminate receive ARP request judge whether it is itself with
And the operation of return communication address；It is not in that a large amount of ARP request blocking is normal for entire virtualized network environment
Business processing, effect are more preferable.
Further, increased due to virtual machine convenient for the variation with actual conditions, deleted, adjusted, in virtualization network rings
Under border, virtual machine and its mailing address may be frequently found to change, therefore the update of routing table is also one in this scenario
Key point.Specifically, the update operation of routing table can perceive that there are triggerings when following situations in virtual router: it is newly-increased by
The virtual machine of self-management is adjusted by the former virtual machine of self-management or is gone offline, by the active and standby virtual machine of same business of self-management
Switching, receive routing table update instruction in any one.Certainly, actual conditions are complex, can not enumerate,
But it is all to will affect the operation communicated with target virtual machine and all trigger the update of routing table, because only that correctly routing
Table just can guarantee effective progress of communication.
Further, after the completion of routing table update, for the ease of this information of the SDN controller timely learning on upper layer,
New routing table can also be back to the SDN controller on upper layer.That is the SDN control on upper layer is stored with what each virtual router was sent
Newest routing table can control all information from the overall situation.
S102: the mailing address of the second virtual machine corresponding with ARP request is determined according to routing table；
On the basis of S101, current virtual router determines and ARP request pair in conjunction with the routing table that can be got
The mailing address for the second virtual machine (i.e. target virtual machine) answered.
Wherein, routing table described in this step and not merely refer to the virtual machine that current virtual router is managed according to itself
Obtained routing table is established, can also include its routing table got from other virtual routers.Supporting EVPN
A kind of (Ethernet Virtual Private Network is VPN technologies for realizing network double layer intercommunication) technology
In the case of, different virtual routers can establish relationship between the two by way of establishing peer relationship, successfully build
After erecting peer relationship, the information recorded in the available virtual router to opposite end of the virtual router of local terminal, not only
It can also include such as information such as the network topology structures that is constituted between virtual machine including routing table.Therefore, either using current
The routing table recorded in virtual router still passes through the routing table that peer relationship is got from opposite end virtual router,
To realize the purpose for determining the second virtual machine mailing address by routing table.It should also be noted that, different virtual routers
A cluster can be belonged to, different clusters can also be adhered to separately.
Further, some other function can also be realized according to established peer relationship between different virtual routers
Can, such as peer relationship maintain verifying, the transmitting of information, the verifying of information security, opposite end current operating conditions really
Fixed, abnormal discovery, master-slave redundancy etc. and some according to particular/special requirement institutes that may be present all under practical application scene
The function of exploitation herein and is not specifically limited.
S103: being back to the first virtual machine for mailing address, so that the first virtual machine is virtual according to mailing address and second
Machine is communicated.
On the basis of S102, this step is intended to substitute the second virtual machine (destination virtual by current virtual router
Machine), the mailing address of second virtual machine (target virtual machine) is back to the first virtual machine, in order to receive this communicatedly
First virtual machine of location carries out point-to-point communication according to the mailing address and the second virtual machine (target virtual machine).
Information makes the first virtual machine not receive the mailing address or not connect in transmittance process appearance exception in order to prevent
Correct mailing address is received, result feedback can also be carried out from the first virtual machine to virtual router, i.e. the first virtual machine is such as
Fruit has received correct mailing address, feeds back a signal to virtual router；If it is logical that the first virtual machine does not receive this
Believe address, virtual router does not receive the signal from the first virtual machine within a certain period of time, will determine this communicatedly
There is exception in the transmission of location, and then trigger and retransmit operation；If although the first virtual machine has received from virtual router
Data, but mailing address therein is imperfect, and the signal of a mailing address mistake or exception can be also returned to virtual router,
It is final to guarantee that the first virtual machine is allowed to be actually received effectively communicatedly to inform virtual router and trigger corresponding operation
Location.
For ease of understanding, the present embodiment additionally provides a structural schematic diagram as shown in Figure 2 to describe stream shown in FIG. 1
Journey.Respectively 4 different virtual machines on the right side of Fig. 2, respectively virtual machine A, virtual machine B, virtual machine C and virtual machine D, this four
Virtual machine respectively has data connection with the foundation of the virtual router at center, to be sent by the data connection to virtual router
ARP request.Routing table positioned at left side is to be formed and stored in after learning in the virtual router in advance, record have this 4
A virtual machine and its respective corresponding relationship between mailing address.Fig. 2 by virtual machine A to virtual router send ARP request for,
Virtual router determines that virtual machine A wants the target virtual machine communicated according to the parameter combination routing table in ARP request
Mailing address, and the mailing address is finally back to virtual machine A, so that virtual machine A passes through the mailing address and destination virtual
Machine is communicated.
Based on the above-mentioned technical proposal, the application has used the virtual router created using virtualization technology to manage
Each virtual machine by the way of managing each virtual machine, is created compared to simple using entity router also with virtualization technology
Obtained virtual router preferably can carry out information exchange with the virtual machine managed and other virtual routers, can be maximum
Avoid the entity router as caused by agreement disunity between virtual machine and entity router that can not help in degree virtual for answering
The problem of ARP request that machine is initiated, be the appropriate of the influence performance uniformly made of reaching an agreement without virtual machine or entity router
Association.Meanwhile under more cluster scenes, the virtual router of each cluster can also easily carry out information exchange.
Embodiment two
Fig. 3 is referred to, Fig. 3 is a kind of determination method of mailing address in data communications method provided by the embodiments of the present application
Flow chart, on the basis of example 1, the present embodiment specifically provides a kind of method of determining mailing address for S102, wraps
The second virtual machine is included to belong to current virtual router administration or be not belonging to two kinds of situations of management of current virtual router, including with
Lower step:
S201: it is extracted from ARP request and obtains the attribute information of the second virtual machine；
This step, which is intended to extract from ARP request, obtains the attribute information of the second virtual machine (target virtual machine), the attribute
Information may include that the device name of target virtual machine, affiliated cluster, creation time, affiliated grouping, Permission Levels etc. can be helped
Help the parameter that the second virtual machine is distinguished in multi-dummy machine of comforming.
S202: the destination virtual router of the second virtual machine of management is determined according to attribute information；
On the basis of S201, this step is intended to determine management come specific according to the attribute information got this is second virtual
The destination virtual router of machine.
Determining the purpose of virtual router for managing second virtual machine is, if the second virtual machine be not with it is first virtual
When machine is belonged under the management of identical virtual router, second not will record in the routing table of usually current virtual router
The mailing address of virtual machine, therefore also just without normal direction the first virtual machine mailing address, it is also possible to by establishing peer-to-peer
Mode and the second virtual machine of actual management virtual router foundation contact, and further therefrom get record have second void
The routing table of quasi- machine mailing address.
S203: when destination virtual router is itself, the second virtual machine is determined according to the routing table for being recorded in itself
Mailing address；
It is exactly the basis of current virtual router itself that this step, which is established in the destination virtual router that S202 is determined,
On, illustrate management of second virtual machine with the first virtual machine by identical virtual router, i.e. the mailing address note of the second virtual machine
Record directly can determine the logical of the second virtual machine according to the routing table of itself in the routing table of current virtual router
Believe address.
S204: it when destination virtual router is non-self other virtual routers, is established with destination virtual router
Peer relationship obtains the road recorded in destination virtual router by peer relationship if being successfully established peer relationship
By table, and the routing table by getting determines the mailing address of the second virtual machine.
This step is established on other virtual roads that the destination virtual router that S202 is determined is non-present virtual router
On the basis of device, illustrate that the first virtual machine is wanted to be communicated with a virtual machine by another virtual router management,
For this purpose, it present embodiments provides and a kind of realizes two virtual roads of difference by way of establishing peer relationship
By the method for device information interaction, after two different virtual routers are successfully established peer relationship, the virtual road of local terminal
The information that can be stored in the virtual router of opposite end by the acquisition of the peer relationship of foundation by device, including routing table,
The information such as network topology.Current virtual router is getting routing from destination virtual router belonging to the second virtual machine
After table, so that it may obtain the mailing address of the second virtual machine according to the routing table, adhere to different virtual router management separately not
Under the premise of not being isolated between virtual machine, the first virtual machine can be carried out directly by the mailing address and the second virtual machine
Communication.
Further, subsequent for convenience to reuse, it can also be whenever success and a non-self virtual router
After establishing the peer relationship, the peer relationship is just recorded, and corresponding routing table is stored in current virtual flow-line
In the data space of device itself.
For convenience of understanding, the present embodiment also passes through Fig. 4 and is provided in the corresponding structural schematic diagram of above content, deposits in Fig. 4
In two different virtual routers, respectively virtual router X and virtual router Y, wherein virtual machine A, B, C, D are by void
Quasi- router X-tube reason, virtual machine E, F, G, H are managed by virtual machine router Y, i.e. the routing table of virtual router X only records
Virtual machine A, B, C, D communicate with the corresponding relationship between address, the routing table of virtual router Y only record virtual machine E, F, G,
H communicates with the corresponding relationship between address.
For Fig. 4 by taking virtual machine A initiates ARP request to virtual router X as an example, target virtual machine is virtual machine F, therefore
After virtual router X receives the ARP request, it is found that record does not have the mailing address of virtual machine F in target itself routing table, and
Therewith discovery virtual machine F by virtual router Y management, therefore before not having etc. with virtual router Y foundation to body relationship
It puts, will attempt to establish peer relationship with virtual router Y, after peer relationship is successfully established, the peer-to-peer will be passed through
Relation acquisition is stored in the routing table in virtual router Y, and the mailing address of virtual machine F is checked in from the routing table, and most
It is back to virtual machine A eventually.

Current virtual router determines itself current operating status, according to what is divided under application scenarios to operating status
Difference, there may be a variety of, multi-grade, etc. classifications operating status division mode, such as can simply be divided into just
Often (online), abnormal (online), go offline three kinds of states, can also with according to whether the generation that ARP request can be completed answer and operate it
Being divided into can be for answering and and can not be not specifically limited for answering two kinds, etc. herein.
S302: when the operating status of itself, which is unable to complete ARP request generation, to be answered, there is peer relationship to establishing with itself
The virtual router of opposite end sends business trustship request；
This step is established in current virtual router according to the judgement to self-operating state, it is believed that itself is unable to complete
In the generation of ARP request, answers operation, therefore is that generation is allowed to answer operation and continue, and the application, which provides, a kind of has equity to itself foundation
The virtual router of the opposite end of body relationship sends business trustship request, i.e. the operating status to opposite end is good (at least extra
In generation, answers operation processing ability) virtual router seek pick-up service trustship, or agency can be become.
It should be noted that in order to be reduced as far as possible on the influence of the performance of the virtual router of opposite end, the business trustship
Request can be to it is all with itself establish peer relationship opposite end virtual router transmission, to seek most to close wherein
Suitable opposite end virtual router is as trustship virtual router.
S303: trustship virtual router is determined according to the response message received；
On the basis of S302, this step is intended to by current virtual router according to each response message received come really
Determine trustship virtual router, wherein can wrap in the response message and self-operating state is retouched containing each opposite end virtual router
It states, to determine preferred trustship virtual router based on this.
S304: sending itself current routing table to trustship virtual router, and by the ARP of each virtual machine of self-management
Request sends address and is revised as hosts virtual machine.
On the basis of S303, current virtual router can send itself current routing to trustship virtual router
Table, and hosts virtual machine is revised as in the ARP request of each virtual machine of self-management transmission address, so that trustship virtual flow-line
Device helps oneself completion subsequent ARP request generation to answer operation.
Above describe current virtual router oneself active completed according to self-operating state it is some
Corrective operation, but if current virtual router is because failure goes offline or when delay machine, will be unable to execute this operation, therefore may be used also
To judge its operating status by the opposite end virtual router that peer relationship has been established, i.e., according to established peer-to-peer
Relationship determines the operating status of the virtual router of opposite end, and executes operation corresponding with operating status.
Just by taking opposite end virtual router is in the state that goes offline as an example, when the virtual router of local terminal is this case that determination,
The executable operation of one of which are as follows: send the virtual router in the state that goes offline to the SDN controller on upper layer and be currently at
