Description

Method, device and system for processing virtual address

Technical Field

The present application relates to the field of private networks, and in particular, to a method, an apparatus, and a system for processing a virtual address.

Background

An advanced functionality failover that enterprise users typically use in conventional networks. One key technology for implementing failover is that two or more nodes notify the host in the subnet and the mac Address corresponding to the virtual IP of the routing switching device that a switch has occurred by using a broadcast free ARP (Address Resolution Protocol). However, most cloud manufacturers do not support the broadcast function of gratuitous ARP in a VPC environment after adopting an SDN (Software Defined Network) architecture.

In order to meet the above requirements of conventional enterprise users, the prior art provides an ec2aws command line toolkit, and when a problem occurs in monitoring, a user calls these APIs (Application Programming interfaces) to move a second private IP on a eni network card (elastic network card) among multiple ec2 instances, but based on the above scheme, virtual IP address switching needs a long time, which may be up to 30-45 seconds or longer.

Under the above operating environment, the present application provides a processing method of virtual addresses as shown in fig. 3. Fig. 3 is a flowchart of a processing method of a virtual address according to an embodiment of the present application. As shown in fig. 3, the method includes:

step S32, the virtual switch performs address resolution protocol statistics on the virtual address to obtain a statistical value.

Specifically, as with the ASW, a High available virtual address (height VIP) may be regarded as a secondary private ip of the virtual machine instance, but in order to implement fast switching of the height, the virtual switch may count the arp on the height, so as to determine whether the height is on a virtual machine in the physical machine where the virtual switch is located, that is, whether the height belongs to the virtual machine. For example, the virtual switch may send an arp-request message to the virtual machine at regular time, and if the havip belongs to the virtual machine, the virtual switch may reply the arp-request message to the virtual switch, so that the virtual switch may perform arp statistics on the arp-request message to obtain a statistical value of the arp statistics.

In step S34, the virtual switch acquires the physical machine corresponding to the virtual address from the data forwarding gateway.

Specifically, the data forwarding gateway may be XGW, and the physical machine may be an NC in the private network VPC. XGW stores vm-nc list, that is, XGW stores the corresponding relationship between havip and nc. The virtual switch can acquire which physical machine the havip is on by querying XGW, so that whether the state of the havip managed by the control system is consistent with the internal state of the virtual machine can be determined without the need for the control system to manage/query the state of each virtual machine and the state of the havip by itself.

Step S36, the virtual switch processes the virtual machine based on the physical machine corresponding to the statistical value and the virtual address.

Specifically, the virtual switch may determine whether a havip belongs to the virtual machine through a statistical value of arp statistics, thereby determining whether the virtual machine is in a master state or a slave state, and further process the virtual machine or other virtual machines according to the statistical value, so as to ensure that all virtual machines in the slave state can know an ip address of the virtual machine in the master state.

In addition, the virtual switch can process the control system through the statistical value of the arp statistics and the obtained physical machine where the havip is located, so that the state managed by the control system is consistent with the state in the virtual machine.

It should be noted that, the execution sequence of the step S32 and the step S34 may be to execute the step S32 first and then execute the step S34, or execute the step S32 and the step S34 at the same time, which is not specifically limited in this application.

In the method provided in embodiment 1 of the present application, the virtual switch performs address resolution protocol statistics on the virtual address to obtain a statistical value, and obtains a physical machine corresponding to the virtual address from the data forwarding gateway, and further processes the virtual machine based on the statistical value and the physical machine corresponding to the virtual address, so as to achieve the purpose of fast switching of the virtual address.

It is easy to notice that the virtual switch processes the virtual machines according to the statistical value counted by the address resolution protocol and the physical machines corresponding to the virtual addresses acquired from the data forwarding gateway, compared with the prior art, the control system does not need to manage/query the states of each virtual machine and the havip at regular time, the arp statistical method is faster than the AWS toolkit, and the arp statistical function and the state comparison are realized through the virtual switch, the load of the control system cannot increase exponentially, so that the inconsistency of the experience is reduced, the identity recognition accuracy is improved, and the technical effect of the experience of the user is improved.

Therefore, the solution of embodiment 1 provided by the present application solves the technical problem that the processing method of the virtual address in the prior art is low in efficiency.

In the above embodiments of the present application, the method further includes the following steps:

in step S362, the virtual switch determines whether the statistic is greater than a preset value, and whether the physical machine corresponding to the virtual address is the physical machine to which the virtual switch belongs.

Specifically, a preset value may be set according to an experiment to distinguish whether a havip belongs to the virtual machine, for example, the virtual switch sends an arp-request packet to the virtual machine at regular time, and since the virtual machine does not reply the arp-reply packet when the havip does not belong to the virtual machine, a statistical value of arp statistics obtained by the virtual switch is 0. Therefore, the above preset value may be 0.

Step S364, if the statistic value is greater than the preset value, the virtual switch processes the virtual machine.

Specifically, if the statistical value of the arp statistics is greater than 0, it indicates that the virtual switch receives an arp-reply packet sent by the virtual machine, that is, the havip belongs to the virtual machine, and it may be further determined that the virtual machine is in a master state and other virtual machines are in a slave state, so that the virtual switch may only process the virtual machine in the slave state.

Optionally, when the statistical value is less than or equal to the preset value, the virtual switch does not process the virtual machine or the control system.

Specifically, if the statistical value of the arp statistics is 0, it indicates that the virtual switch has not received an arp-reply packet sent by the virtual machine, that is, the havip does not belong to the virtual machine, and it may be further determined that the virtual machine is in a slave state, and the virtual switch does not perform any processing.

Step S366, if the statistical value is greater than the preset value and the physical machine corresponding to the virtual address is not the physical machine to which the virtual switch belongs, the virtual switch processes the control system.

Specifically, since the virtual switch does not perform any processing when the statistical value of the arp statistics is 0, it may be further determined whether the physical machine where the havip is located is the physical machine where the virtual switch is located, that is, whether the havip is located on the physical machine, when the statistical value of the arp statistics is greater than 0. If the physical machine is in the control system, the state managed by the control system is consistent with the state in the virtual machine. Otherwise, the state of the control system is not updated, so that the virtual switch can process the control system and update the state of the control system.

In the above embodiment of the present application, in step S364, the virtual switch processes the virtual machine, including:

step S3642, the virtual switch determines that the virtual machine corresponding to the virtual address is in the master state, and sends a notification message to the virtual machine in the slave state, where the notification message includes: and the network address of the virtual machine corresponding to the virtual address.

Specifically, the notification message may be a havinpnotify message, where the message carries an ip address of the virtual machine in the master state. Under the condition that the statistical value of the arp statistics is greater than 0, the virtual switch can determine the virtual machine corresponding to the havip, that is, the virtual machine to which the havip belongs is in the master state, and simultaneously send a havip notification message to notify the virtual machine in the slave state and notify the ip address of the virtual machine in the master state.

It should be noted that, if the virtual switch continuously determines that the statistical value of the arp statistics is greater than 0, the virtual switch continuously sends a havip notify message to the physical machine where the slave virtual machine is located.

In the above embodiment of the present application, after receiving the notification packet, the slave-state virtual machine configures a relay route in the physical machine to which the virtual machine belongs, where the relay route forwards the received packet to the physical machine to which the virtual machine belongs.

Alternatively, the data packet may be sent by a physical machine that does not update the virtual machine location cache.

Specifically, in order to further reduce the switching time of the havip, after receiving the havip notify message, the virtual machine may configure a relay route in the local physical machine, where the relay route may relay a data packet that is sent by the VM-location cache and is not updated in time, and forward the data packet to the NC where the VM is located in the state of the mater. Therefore, when failover occurs, the physical machine which is not in time to update the traffic sent to the virtual machine in the slave state can be forwarded to the virtual machine in the master state again.

It should be noted that, the virtual machine in the master state may configure a direct route in the local physical machine where the virtual machine is located, and point the location of the havip to the virtual machine.

In the above embodiment of the present application, in step S366, the virtual switch processes the control system, including:

step S3662, the virtual switch sends a call request to the control system, where after receiving the call request, the control system controls the physical machine corresponding to the virtual address in the data forwarding gateway to update to the physical machine to which the virtual switch belongs.

Specifically, when the virtual switch determines that the state of the control system is not updated, the virtual switch may call an API of the control system to notify the update state of the control system, and after receiving the call request, the control system may allocate the dispatch to XGW, and direct the location of the havip to the physical machine. The virtual switch detects that the states of the two are consistent in the subsequent time, and therefore the API notification management and control are not called any more.

In the above embodiment of the present application, in step S32, the virtual switch performs address resolution protocol statistics on the virtual address to obtain a statistical value, including:

step S322, the virtual switch sends an address resolution protocol request to the virtual machine corresponding to the virtual address.

In step S324, the virtual switch receives an arp response returned by the virtual machine based on the arp request.

Step S326, the virtual switch obtains a statistic value based on the address resolution protocol response.

Specifically, on a data level, the virtual machine sends an arp-request message to the virtual machine, and queries whether the havip is on the virtual machine. If the virtual machine replies an arp-reply message to the virtual switch, the virtual switch can obtain the statistical value of arp statistics according to whether the arp-reply message is received or not, and if the arp-reply message is received, the statistical value is greater than 0; and if the arp-reply message is not received, the statistic value is 0.

In the above embodiment of the present application, the method further includes:

in step S38, the virtual switch obtains the gratuitous arp packet sent by the virtual machine.

Step S310, the virtual switch processes the virtual machine based on the toll free address resolution protocol data packet.

Specifically, when failover occurs, the virtual machine may also actively send a free arp packet, and the virtual switch can capture the event, so that after receiving the free arp, the virtual switch may send a havingnotify message to notify the virtual machine in the slave state, and notify the ip address of the virtual machine in the master state.

It should be noted that, if the virtual switch continuously receives a free arp, the virtual switch continuously sends a havip notify message to the physical machine where the virtual machine in the slave state is located.

In the above embodiment of the present application, the other physical machines except the physical machine to which the virtual switch belongs obtain the physical machine corresponding to the virtual address from the data forwarding gateway, and update the virtual machine location caches in the other physical machines.

Specifically, other physical machines on the VPC may periodically query XGW for the physical machine where the havip is located, and thus, a time later, the vm-location cache on the physical machine is also updated, so that the traffic can be sent to the new physical machine.

In the above embodiment of the present application, the virtual switch performs address resolution protocol statistics on the virtual address through the started preset process, so as to obtain a statistical value.

Specifically, the preset process may be a daemon process started by the virtual switch in the user mode, and the daemon process may collect statistics of arp statistics of havip.

In the above embodiments of the present application, the virtual switch performs address resolution protocol statistics on the virtual address at regular time, and obtains the physical machine corresponding to the virtual address at regular time.

Specifically, the virtual switch may send an arp-request message to the virtual machine at intervals of 10 seconds, and collect statistics of arp statistics of havip through the daemon. Meanwhile, the virtual switch will periodically query XGW for the physical machine where havip is located.

In the above embodiments of the present application, the virtual switch receives virtual address information sent by the control system, where the virtual address information is sent by the control system when a node is added or deleted.

Specifically, for each havip, the control system issues the havip information to the virtual switch on the physical machine when the user adds or deletes the ha node. For a havip under a single VPC, information for a group of havips (node1, node2 …) is available.

For example, fig. 4 shows the call sequence when a havip switch occurs, and as shown in fig. 4, the ip address of NC1 is 10.10.10.1, the ip address of NC2 is 10.10.10.2, the ip address of ECS1 on NC1 is 192.168.0.1, and the ip address of ECS3 on NC2 is 192.168.0.2. ECS1 on NC1 is in the master state and ECS1 on NC2 is in the slave state, so that the virtual switch on NC1 can send a havip notify to NC2, informing that the ip address of the virtual machine in the master state is 192.168.0.1. In addition, NC1 adds a direct route havip locally to ECS1 on NC1, and NC2 adds a relay route havip locally to ECS1 on NC 1. Meanwhile, the virtual switch on NC1 may inform the controller with call-api, VPC controller updates the vm-NC table on XGW, pointing the location of havip to ECS1 in NC1, vm-NC table is updated to 192.168.0.1 on 10.10.10.1. In addition, NC1 and NC2 may synchronize vm-location to XGW.

As can be seen from the above, when a havip switch occurs, all the operations are completed by each physical machine NC, and the VPC controller (i.e., the control system described above) only needs to update the vm-NC table on XGW after the API is called.

As shown in fig. 5, the daemon process work logic on the virtual switch is as follows: the virtual switch sends arp-request to the virtual machine at regular time, and statistics are collected; at the same time, the virtual switch synchronizes vm-location state from XGW in time. If the arp statistic is larger than 0, continuously sending a havip notify notification to an NC where the VM in the slave state is located, and locally adding a havip- > VM route; meanwhile, if the havip is not on the physical machine, calling a controller API to update the vm-nc table on XGW; if havip is on the physical machine, it is determined that the controller state is up-to-date and no processing is required. And if the arp statistic is equal to 0, adding a relay route after receiving the havip notify notification, and meanwhile, determining that the state of the controller is up-to-date no matter whether the havip is on the physical machine or not, and not needing any processing.

By the scheme, the method for fast switching the havip based on the ARP statistics and the relay routing is simple in structure, the switching time can be controlled within 5 seconds, the switching time is obviously shortened, and the controller is only responsible for informing XGW of the state when switching is performed again, so that the load is not exponentially increased, and large-scale virtual IP service can be provided in the environment of a cloud network.

It should be noted that, for simplicity of description, the above-mentioned method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present application is not limited by the order of acts described, as some steps may occur in other orders or concurrently depending on the application. Further, those skilled in the art should also appreciate that the embodiments described in the specification are preferred embodiments and that the acts and modules referred to are not necessarily required in this application.

Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present application may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present application.

Example 2

According to an embodiment of the present application, there is also provided a virtual address processing apparatus for implementing the virtual address processing method, as shown in fig. 6, the apparatus 600 includes: a statistics module 602, an acquisition module 604, and a processing module 606.

The statistical module 602 is configured to perform address resolution protocol statistics on the virtual address to obtain a statistical value; the obtaining module 604 is configured to obtain a physical machine corresponding to the virtual address from the data forwarding gateway; the processing module 606 is configured to process the virtual machine based on the physical machine corresponding to the statistical value and the virtual address.

Specifically, the data forwarding gateway may be XGW, and the physical machine may be an NC in the private network VPC. XGW stores vm-nc list, that is, XGW stores the corresponding relationship between havip and nc.

It should be noted here that the statistical module 602, the obtaining module 604, and the processing module 606 correspond to steps S32 to S36 in embodiment 1, and the three modules are the same as the corresponding steps in the implementation example and application scenario, but are not limited to the disclosure in embodiment 1. It should be noted that the above modules may be operated in the computer terminal 10 provided in embodiment 1 as a part of the apparatus.

In the method provided by embodiment 2 of the present application, the virtual switch performs address resolution protocol statistics on the virtual address through the statistics module to obtain a statistical value, and obtains the physical machine corresponding to the virtual address from the data forwarding gateway through the acquisition module, and further processes the virtual machine through the processing module based on the statistical value and the physical machine corresponding to the virtual address, so as to achieve the purpose of fast switching of the virtual address.

Therefore, the solution of the foregoing embodiment 2 provided by the present application solves the technical problem that the processing method of the virtual address in the prior art is low in efficiency.

In the above embodiment of the present application, the apparatus further includes: the device comprises a judgment submodule, a first processing submodule and a second processing submodule.

The judging submodule is used for judging whether the statistical value is larger than a preset value or not and whether the physical machine corresponding to the virtual address is the physical machine to which the virtual switch belongs or not; the first processing submodule is used for processing the virtual machine if the statistic value is larger than a preset value; and the second processing submodule is used for processing the control system if the statistical value is greater than the preset value and the physical machine corresponding to the virtual address is not the physical machine to which the virtual switch belongs.

Specifically, a preset value may be set according to an experiment, so as to distinguish whether the havip belongs to the virtual machine, for example, the virtual switch sends an arp-request message to the virtual machine at regular time, because the virtual machine does not reply the arp-request message when the havip does not belong to the virtual machine, the statistical value of the arp statistics obtained by the virtual switch is 0. Therefore, the above preset value may be 0.

Example 3

According to an embodiment of the present application, there is also provided a system for processing a virtual address, as shown in fig. 7, the system including: a data forwarding gateway 72, a virtual switch 74, and a virtual machine 76.

The data forwarding gateway 72 is configured to store a corresponding relationship between a virtual address and a physical machine; the virtual switch 74 is configured to perform address resolution protocol statistics on the virtual address to obtain a statistical value, acquire a physical machine corresponding to the virtual address from the data forwarding gateway, and process the virtual machine 76 based on the statistical value and the physical machine corresponding to the virtual address.

Specifically, like the ASW, a high available virtual address (havip) may be regarded as a secondary private ip of the virtual machine instance, but to implement fast switching of the havip, the virtual switch may count the arp on the havip, so as to determine whether the havip is on a virtual machine in the physical machine where the virtual switch is located, that is, whether the havip belongs to the virtual machine. For example, the virtual switch may send an arp-request message to the virtual machine at regular time, and if the havip belongs to the virtual machine, the virtual switch may reply the arp-request message to the virtual switch, so that the virtual switch may perform arp statistics on the arp-request message to obtain a statistical value of the arp statistics.

The data forwarding gateway may be XGW and the physical machine may be an NC in the private network VPC. XGW stores vm-nc list, that is, XGW stores the corresponding relationship between havip and nc. The virtual switch can acquire which physical machine the havip is on by querying XGW, so that whether the state of the havip managed by the control system is consistent with the internal state of the virtual machine can be determined without the need for the control system to manage/query the state of each virtual machine and the state of the havip by itself.

The virtual switch can determine whether the havip belongs to the virtual machine through the statistical value of the arp statistics, thereby determining whether the virtual machine is in a master state or a slave state, and further processing the virtual machine or other virtual machines according to the statistical value to ensure that all the virtual machines in the slave state can know the ip address of the virtual machine in the master state.

In addition, the virtual switch can process the control system through the statistical value of the arp statistics and the obtained physical machine to which the havip belongs, so that the state managed by the control system is consistent with the state in the virtual machine.

In the method provided by the foregoing embodiment 3 of the present application, the virtual switch performs address resolution protocol statistics on the virtual address to obtain a statistical value, and obtains a physical machine corresponding to the virtual address from the data forwarding gateway, and further processes the virtual machine based on the statistical value and the physical machine corresponding to the virtual address, so as to achieve the purpose of fast switching of the virtual address.

Therefore, the solution of the above embodiment 3 provided by the present application solves the technical problem that the processing method of the virtual address in the prior art is low in efficiency.

In the above embodiment of the present application, the virtual switch is configured to determine whether the statistic value is greater than the preset value, and whether the physical machine corresponding to the virtual address is a physical machine to which the virtual switch belongs, if the statistic value is greater than the preset value, the virtual machine is processed, and if the statistic value is greater than the preset value, and the physical machine corresponding to the virtual address is not a physical machine to which the virtual switch belongs, the control system is processed.

If the statistical value of the arp statistics is greater than 0, it indicates that the virtual switch receives an arp-reply message sent by the virtual machine, that is, the havip belongs to the virtual machine, and it can be further determined that the virtual machine is in a master state and other virtual machines are in a slave state, so that the virtual switch can only process the virtual machine in the slave state.

Optionally, the virtual switch is configured to not process the virtual machine or the control system when the statistical value is less than or equal to the preset value.

Since the virtual switch does not perform any processing when the statistical value of the arp statistics is 0, it can be further determined whether the physical machine where the havip is located is the physical machine where the virtual switch is located, that is, whether the havip is located on the physical machine, when the statistical value of the arp statistics is greater than 0. If the physical machine is in the control system, the state managed by the control system is consistent with the state in the virtual machine. Otherwise, the state of the control system is not updated, so that the virtual switch can process the control system and update the state of the control system.

In the above embodiment of the present application, the virtual switch is further configured to determine that the virtual machine corresponding to the virtual address is in a master state, and send a notification message to the virtual machine in a slave state, where the notification message includes: and the network address of the virtual machine corresponding to the virtual address.

In the foregoing embodiment of the present application, the slave-state virtual machine is configured to configure a relay route in the physical machine to which the virtual machine belongs after receiving the notification packet, where the relay route forwards the received packet to the physical machine to which the virtual machine belongs.

In the above embodiment of the present application, the virtual switch is further configured to send a call request to the control system; and the control system is used for controlling the physical machine corresponding to the virtual address in the data forwarding gateway to be updated to the physical machine to which the virtual switch belongs after receiving the calling request.

In the above embodiment of the present application, the virtual switch is further configured to send an address resolution protocol request to a virtual machine corresponding to the virtual address, receive an address resolution protocol response returned by the virtual machine based on the address resolution protocol request, and obtain the statistical value based on the address resolution protocol response.

In the above embodiment of the present application, the virtual machine is configured to send a gratuitous address resolution protocol data packet to the virtual switch; the virtual switch is further configured to process the virtual machine based on the gratuitous address resolution protocol data packet.

In the above embodiment of the present application, other physical machines except the physical machine to which the virtual switch belongs are used to obtain the physical machine corresponding to the virtual address from the data forwarding gateway, and update the virtual machine location caches in the other physical machines.

In the above embodiments of the present application, the virtual switch includes: a preset process that has been started.

The preset process is used for carrying out address resolution protocol statistics on the virtual address to obtain a statistic value.

In the above embodiment of the present application, the virtual switch is further configured to perform address resolution protocol statistics on the virtual address at regular time, and obtain the physical machine corresponding to the virtual address at regular time.

In the above embodiments of the present application, the control system is further configured to send the virtual address information to the virtual switch when a node is added or deleted.
