Referring to fig. 1, the network includes a primary Virtual router and a standby Virtual router, where a Virtual Internet Protocol (VIP) address of a host running on the primary Virtual router is 10.113.0.181, and a VIP address of a host running on the standby Virtual router is 10.113.0.182. Fig. 2 is a diagram illustrating an application scenario of another migration method for a virtual router according to an embodiment of the present invention. Referring to fig. 2, when the primary virtual router needs to be migrated to the running host of the standby virtual router, the migration of the primary virtual router can be implemented by modifying the VIP address of the running host of the primary virtual router from 10.113.0.181 to 10.113.0.182.
Based on the application scenarios shown in fig. 1 and fig. 2, the technical solution of the embodiment of the present invention is provided.
Fig. 3 is a schematic flowchart of a migration method of a virtual router according to an embodiment of the present invention, where the method is applied to a source host, and as shown in fig. 3, the flow may include:
step 301: a migration request of a first virtual router is received.
In the embodiment of the present invention, the first Virtual Router is a Virtual Router to be migrated, and it should be noted that a Virtual Router (VR) is a logical device that implements function simulation of a physical Router on a software layer and a hardware layer; hosts are end devices for sending and receiving information, each host having a unique VIP address.
In the embodiment of the invention, a user can send a migration request for migrating the first virtual router to other hosts to the source host.
Step 302: and determining a destination host according to the migration request of the first virtual router.
In this embodiment of the present invention, the migration request of the first virtual router may include: migration authority information of the first virtual router, parameter verification information of the first virtual router, configuration information of the first virtual router, and a VIP address of the destination host. Here, the migration permission information of the first virtual router is used to represent whether the first virtual router has permission to migrate out of the source host, the parameter verification information of the first virtual router is used to represent whether the parameter of the first virtual router is correct, and the configuration information of the first virtual router is used to represent whether the data format migrated by the first virtual router is correct.
In the embodiment of the invention, after a source host receives a migration request of a first virtual router, the migration authority information of the first virtual router is verified, the parameter verification information of the first virtual router is verified under the condition that the migration authority information is verified, the configuration information of the first virtual router is checked under the condition that the parameter verification information is verified, and after no error is confirmed, a destination host is determined according to a VIP (very important person) address of the destination host and the first virtual router starts to be migrated.
Step 303: and sending the cache data of the first virtual router to the destination host, so that the destination host determines the second virtual router and writes the cache data of the first virtual router into the second virtual router.
In some embodiments, sending the cached data of the first virtual router to the destination host comprises:
sending a migration request of a first virtual router to a destination host;
after receiving the confirmation information sent by the target host, sending the cache data of the first virtual router to the target host; the confirmation information is information that the destination host verifies the migration request passing through the first virtual router; the confirmation information includes: first acknowledgement information or second acknowledgement information; the first confirmation information is information sent by the destination host under the condition that a standby virtual router is not configured; the second acknowledgement information is information that the destination host transmits when the standby virtual router is configured.
In the embodiment of the invention, when a client accesses a virtual router, the virtual router correspondingly establishes a Session (Session), and the Session records the request of the client for accessing the virtual router and the reply information of the virtual router responding the client, namely the Session is the cache data of the virtual router. Illustratively, the cache data of the first virtual router indicates that, when the first virtual router runs on the source host, each client communicates with the first virtual router to cache data in the process, and the first virtual router can read the cache data and can execute corresponding business operations according to the cache data.
In this embodiment of the present invention, the second virtual router refers to a virtual router running on the destination host, and the second virtual router may also execute the service operation of the first virtual router by writing the cache data of the first virtual router into the second virtual router.
In the embodiment of the invention, the standby virtual router is a virtual router which is not connected with the Internet, namely, the standby virtual router does not have cache data and can not execute related business operation. If the cache data of the relevant service is written into the standby virtual router, the standby virtual router can execute the relevant service operation.
In the embodiment of the invention, a source host sends a migration request of a first virtual router to a destination host according to a VIP (very important person) address of the destination host, the destination host verifies the received migration request, after verifying that the first virtual router has the authority of migrating to the destination host, the destination host sends confirmation information to the source host, the source host sends cache data of the first virtual router to the destination host after receiving the confirmation information sent by the destination host, and the destination host determines a second virtual router and writes the cache data of the first virtual router into the second virtual router, so that the second virtual router can execute business operation of the first virtual router, and the first virtual router is migrated to the destination host from the source host.
In the embodiment of the invention, after receiving a migration request, a destination host firstly determines whether a standby virtual router is currently configured on the destination host, and if the standby virtual router is not configured, the destination host sends first confirmation information to a source host, and the source host needs to migrate a first virtual router and cache data of the first virtual router to the destination host, so that migration of the first virtual router is realized; if the standby virtual router is configured and the second confirmation information is sent to the source host, the source host only needs to write the cache data of the first virtual router into the standby virtual router in the destination host, and therefore the first virtual router is switched to the standby virtual router.
In the embodiment of the present invention, as shown in fig. 4, a first virtual router runs on a source host, and when the source host receives a migration request of the first virtual router, the source host determines a destination host according to the migration request, for example, when the destination host is a host 1, after the host 1 receives the migration request, it is determined that no standby virtual router is configured in the host 1, the host 1 sends first confirmation information to the source host, and after the source host receives the first confirmation information, the source host migrates the first virtual router and the cache data of the first virtual router to the host 1, that is, completes the migration of the first virtual router.
In the embodiment of the present invention, as shown in fig. 4, when the destination host is the host 2, and after the host 2 receives the migration request, it is determined that the host 2 is configured with the standby virtual router, the host 2 sends the second acknowledgement information to the source host, and after the source host receives the second acknowledgement information, the source host sends the cache data of the first virtual router to the host 2, and the host 2 writes the cache data of the first virtual router into the standby virtual router, that is, completes the switching from the first virtual router to the standby virtual router.
In practical applications, the steps 301 to 303 are implemented by a Processor based on an electronic Device, and the Processor may be at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a Central Processing Unit (CPU), a controller, a microcontroller, and a microprocessor.
It can be seen that, in the embodiment of the present invention, when receiving a migration request of a first virtual router, a source host determines a destination host according to the migration request, and after receiving confirmation information sent by the destination host, sends cache data of the first virtual router to the destination host, and the destination host determines a second virtual router, and writes the cache data of the first virtual router into the second virtual router, so that the second virtual router can execute a service operation of the first virtual router, that is, the migration of the first virtual router from the source host to the destination host is completed. It can be seen that, in the embodiment of the present invention, when the first virtual router is migrated, the cache data in the first virtual router is migrated synchronously, so that the original service can also be recovered synchronously after the first virtual router is migrated to the destination host, service interruption caused by virtual router migration is not caused, migration time of the first virtual router can be shortened, and use experience of a user is effectively improved.
In some embodiments, after sending the cache data of the first virtual router to the destination host in case of receiving the first acknowledgement information, the method further includes:
and deleting the first virtual router after receiving the information of the completion of the writing of the cache data sent by the destination host.
In some embodiments, when the destination host is not configured with a virtual standby router, after the cache data of the first virtual router is written into the second virtual router created by the destination host, the destination host sends information that the cache data is written into the source host, and after the source host receives the information that the cache data is written into the destination host, it may be determined that the first virtual router and the cache data of the first virtual router have been migrated to the destination host, and then the virtual router configured on the source host does not perform related business operations any more, and therefore, the source host deletes the first virtual router. Therefore, the source host deletes the first virtual router after the migration of the first virtual router is completed, and the occupation of network resources by useless virtual routers can be reduced.
In some embodiments, after sending the cache data of the first virtual router to the destination host in case of receiving the second acknowledgement information, the method further includes:
receiving second identification information of the standby virtual router sent by the destination host;
and determining the identification information of the first virtual router as second identification information.
In some embodiments, the identification information (Role) is used to identify the attribute of the virtual router, and the identification information of the virtual router may include, for example: if the identification information of the virtual router is master, the virtual router executes the relevant service operation under the normal condition, and if the identification information of the virtual router is back up, the virtual router replaces the virtual router (master) to execute the relevant service operation when the virtual router (master) has a fault.
In some embodiments, in a case where the source host receives the second confirmation information, it is described that the destination host is configured with the virtual standby router, and determines that the virtual standby router is the second virtual router, the source host sends the cache data of the first virtual router to the destination host, the destination host sends the second identification information of the standby virtual router to the source host, and the source host may use the second identification information as the identification information of the first virtual router.
It can be seen that, after the first virtual router is switched to the standby virtual router, the identification information of the standby virtual router is used as the identification information of the first virtual router, that is, the attribute conversion between the first virtual router and the standby virtual router is completed, which is beneficial for a user to determine the operation condition of the virtual router according to the identification information of the virtual router.
In some embodiments, after sending the cache data of the first virtual router to the destination host, the method further includes:
and sending the first identification information of the first virtual router to the destination host, so that the destination host determines the identification information of the second virtual router as the first identification information.
In some embodiments, the source host sends the first identification information of the first virtual router to the destination host, and the destination host uses the first identification information of the first virtual router as the identification information of the second virtual router, that is, identifies the attribute of the second virtual router, thereby determining the operation condition of the second virtual router.
Fig. 5 is a schematic flowchart of another migration method of a virtual router, which is provided in an embodiment of the present invention and is applied to a destination host, as shown in fig. 5, the flow may include:
step 501: and receiving the cache data of the first virtual router sent by the source host.
In the embodiment of the present invention, the cache data represents service cache data of the first virtual router when running on the source host, and the source host sends the cache data of the first virtual router to the destination host.
Step 502: and determining a second virtual router, and writing the cache data of the first virtual router into the second virtual router.
In the embodiment of the invention, the destination host determines the second virtual router and writes the cache data of the first virtual router into the second virtual router, so that the second virtual router can execute the service operation of the first virtual router, thereby completing the migration of the first virtual router from the source host to the destination host.
It can be seen that, in the embodiment of the present invention, after the destination host receives the cache data of the first virtual router sent by the source host, the destination host determines the second virtual router, and writes the cache data of the first virtual router into the second virtual router, so that the second virtual router can execute the service operation of the first virtual router, that is, the migration of the first virtual router from the source host to the destination host is completed. It can be seen that, in the embodiment of the present invention, when the first virtual router is migrated, the cache data in the first virtual router is migrated synchronously, so that the original service can be recovered synchronously after the first virtual router is migrated to the destination host.
In some embodiments, receiving the cache data of the first virtual router sent by the source host includes:
receiving a migration request of a first virtual router sent by a source host;
sending confirmation information to the source host under the condition of verifying the migration request passing through the first virtual router; the confirmation information includes: first acknowledgement information or second acknowledgement information; the first confirmation information is information sent under the condition that a standby virtual router is not configured; the second confirmation information is information transmitted under the condition that the standby virtual router is configured;
and receiving the cache data of the first virtual router sent by the source host.
In some embodiments, after receiving a migration request of a first virtual router, a destination host determines whether a standby virtual router is currently configured on the destination host, and if the standby virtual router is not configured, sends first confirmation information to a source host; and if the standby virtual router is configured, sending second confirmation information to the source host.
In some embodiments, determining the second virtual router comprises:
under the condition of sending first confirmation information to the source host, creating a virtual router, and determining the created virtual router as a second virtual router;
and under the condition of sending second confirmation information to the source host, determining that the standby virtual router is the second virtual router.
In some embodiments, in the case of sending the first acknowledgement information to the source host, which indicates that the destination host is not configured with a standby virtual router, the source host needs to migrate the first virtual router and the cache data of the first virtual router to the destination host, and therefore, the destination host creates one virtual router and determines the created virtual router as a second virtual router, where the second virtual router may perform related business operations after writing the cache data of the first virtual router.
In some embodiments, in the case of sending the second acknowledgement information to the source host, which indicates that the destination host is configured with the standby virtual router, the source host only needs to send the cache data of the first virtual router to the destination host, and therefore, the destination host determines the standby virtual router as the second virtual router and writes the cache data of the first virtual router into the second virtual router.
It can be seen that, when the standby virtual router is configured, the destination host determines the standby virtual router as the second virtual router, and when the standby virtual router is not configured, a virtual router is created first, and then the created virtual router is determined as the second virtual router, that is, whether the destination host can execute corresponding operations according to the situation that the standby virtual router is configured can be determined, and the migration efficiency of the first virtual router can be effectively improved.
In some embodiments, in the case of sending the first acknowledgement information to the source host, after writing the cache data of the first virtual router to the second virtual router, information that the writing of the cache data is completed is sent to the source host.
In some embodiments, in the case of sending the second acknowledgement information to the source host, that is, the destination host is configured with the virtual standby router and determines the virtual standby router as the second virtual router, the source host sends the cache data of the first virtual router to the destination host, and the destination host sends the second identification information of the standby virtual router to the source host, and the source host may use the second identification information as the identification information of the first virtual router.
In some embodiments, after receiving the cache data of the first virtual router sent by the source host, the first identification information of the first virtual router is received, and the identification information of the second virtual router is determined to be the first identification information.
