The first route is a real route, the first route can be connected with a plurality of hosts, and each host can be connected with a plurality of virtual devices through one virtual switch. The virtual switch runs on a virtualization platform and supports an OpenFlow protocol, wherein the OpenFlow protocol is a standard protocol between the controller and the switch.

step S21, the first host machine determines the virtual route setting requirement;
step S22, the first host sets a first virtual route in a first virtual device corresponding to the first host according to a virtual route setting requirement, wherein the first virtual route is a virtual route enabling the first host to acquire network information;
when a virtual route on a certain virtual device needs to be queried by other hosts or devices and communication can be established, the host corresponding to the virtual device generates a virtual route setting requirement, and the virtual route setting requirement is used for indicating which virtual device needs to be set with the virtual route so that the virtual route can be interacted with other routes.
After the first host determines the setting requirement of the virtual route, a first virtual route is set at a corresponding position according to the setting requirement of the virtual route, namely, the virtual route is determined at which position of the virtual device is set according to the setting requirement of the virtual route, the virtual route can perform information interaction with other routes through a virtual network, the first virtual route is set at the first virtual device corresponding to the first host, the first host can acquire network information through the first virtual route, and other hosts can also acquire the network information of the first host through the first virtual route.
Further, the determining, by the first host, the virtual routing setting requirement may specifically be:
the first host determines to set a first virtual route at a first network address, wherein the first network address matches routing information of the first virtual route.
Specifically, if there is information at the first network address that can interact with other hosts or virtual devices, the first host may determine that a virtual route needs to be set at the first network address, and therefore, the first host may generate a virtual route setting requirement, and set the first virtual route at the first network address of the first virtual device.
The first virtual route set by the first host is a route belonging to an OpenFlow type, that is, information interaction can be performed with other routes belonging to the OpenFlow type, and the OpenFlow type route is a route in a virtual network.
Step S23, the first host sends the routing information of the first virtual route, so that other hosts or routes can obtain the routing information of the first virtual route, and can obtain the network information through the first virtual route based on the routing information.
After the first virtual route is set by the first host, the route information of the first virtual route is sent out, so that other hosts or routes can acquire the route information of the first virtual route, the first virtual route can be found based on the route information of the first virtual route, and the network information is acquired through the first virtual route.
The routing information of the first virtual route may be: path information of the first virtual route, such as: the first virtual route is specifically set at what position, and is set at the position of the virtual device corresponding to which host.
The first host sends the routing information of the first virtual route, which is not only sent to the mobile edge computing platform, but also issued to all networks except the mobile edge computing platform, so that all routes or hosts in the network can find the first virtual route through the routing information, thereby realizing information interaction.
Specifically, when a virtual route needs to be created at a first virtual device, a first host creates a first virtual route for the first virtual device, and then issues route information of the first virtual route to a network, so that all routes or hosts in the network can find the first virtual route through the route information; and then, the first host acquires the network information through the first virtual route, and after the first host acquires the network information, other hosts or routes need to acquire the network information from the first host through the first route if the other hosts or routes want to acquire the network information, so that all the routes or hosts in the network can acquire the network information except the first virtual route.
Further, the first host may also obtain routing information of the virtual route sent by the other host, that is:
the first host acquires the routing information of the sixth virtual route sent by the third host, and the first host acquires the information on the sixth virtual device based on the routing information of the sixth virtual route, and the sixth virtual route is arranged on the sixth virtual device.
The first host can send the routing information of the first virtual route based on the first virtual route set by the first virtual device, so that other hosts or devices can acquire the information on the first virtual device based on the routing information of the first virtual route; the first host may also send routing information based on virtual routes set on other hosts, such as: and the third host is provided with sixth virtual equipment, creates a corresponding sixth virtual route for the sixth virtual equipment, and then sends out the route information of the sixth virtual route so that other hosts can acquire the information on the third host based on the route information of the sixth virtual route.
The first host acquires the routing information of a sixth virtual route sent by the third host, and if the first host needs to perform information interaction with sixth virtual equipment on the third host, the interaction can be performed based on the sixth virtual route, that is, the information on the first host is sent to the sixth virtual equipment based on the sixth virtual route, or the information on the sixth virtual equipment is sent to the first host or the first virtual equipment on the first host based on the sixth virtual route, so that the interaction between the first virtual equipment and the sixth virtual equipment is realized.
The virtual network management method disclosed by the embodiment is applied to a mobile edge computing platform, wherein the mobile edge computing platform at least comprises at least one host, a first route connected with the at least one host, and at least one virtual device corresponding to the at least one host, the at least one host at least comprises the first host, the first host determines a virtual route setting requirement, a first virtual route is set on the first virtual network device corresponding to the first host according to the virtual route setting requirement, the first virtual route is a virtual route which can enable the first host to acquire network information, and route information of the first virtual route is sent, so that other hosts or routes can acquire the route information of the first virtual route, and the network information can be acquired through the first virtual route based on the route information. According to the scheme, when the first host determines that the virtual route needs to be set in the mobile edge computing platform, the first virtual route is set on the first virtual device, and the first host can acquire the network information through the first virtual route, so that the network information can be acquired through the first virtual route and information interaction is performed between the first virtual route and other routes, and the problem that various dynamic routing protocols cannot be supported in the prior art is solved.
The embodiment discloses a virtual network management method, a flowchart of which is shown in fig. 3, and the method includes:
step S31, the first host determines a deletion request for deleting the first virtual route set in the first virtual device;
step S32, the first host deletes the first virtual route set on the first virtual device based on a requirement for deleting the first virtual route set on the first virtual device, and meanwhile deletes the route information of the first virtual route sent by the first host.
The first virtual device corresponding to the first host may set the first virtual route based on the actual usage requirement, or may delete the first virtual route based on the actual usage requirement.
When determining that the network information at the first network address does not need to be acquired by other hosts or routes any more, or the first network address does not need to acquire the relevant information of other hosts or routes any more; or, the first virtual device no longer needs to interact with other hosts or routes, and then determines a deletion requirement, where the deletion requirement is a deletion requirement for deleting the first virtual route set in the first virtual device.
Then, the first host directly deletes the first virtual route set on the first virtual device based on the deletion requirement, and at the same time, deletes the route information of the first virtual route sent by the first host, so as to avoid that when other hosts or routes prepare to acquire information or send information through the route information of the first virtual route, it is detected that no corresponding virtual route exists at the route information of the first virtual route, thereby determining that the route information is invalid route information, which causes waste of communication resources.
Further, the deletion requirement may also be a deletion requirement of the virtual device.
The first host determines a deletion requirement for deleting the first virtual device, deletes the first virtual device and the first virtual route set on the first virtual device based on the deletion requirement for deleting the first virtual device, and deletes the route information of the first virtual route sent by the first host.
When the first host does not need the first virtual device any more, the first host generates a deletion requirement of the first virtual device, executes the deletion requirement of the first virtual device, and deletes the first virtual route set on the first virtual device and the route information of the first virtual route sent by the first host at the same time of deleting the first virtual device, so as to prevent the route information of the first virtual route sent by the first host from becoming invalid route information.
If the first virtual device is deleted, the first virtual route no longer has an existing basis, and therefore, the first virtual route is also deleted at the same time.
The virtual network management method disclosed by the embodiment is applied to a mobile edge computing platform, wherein the mobile edge computing platform at least comprises at least one host, a first route connected with the at least one host, and at least one virtual device corresponding to the at least one host, the at least one host at least comprises the first host, the first host determines to delete a deletion demand set on the first virtual route, the first virtual route set on the first virtual device is deleted according to the demand for deleting the first virtual route set on the first virtual device, and meanwhile, route information of the first virtual route sent by the first host is deleted. According to the scheme, when the first host determines that the virtual route needs to be set in the mobile edge computing platform, the first virtual route is set on the first virtual equipment, and the first host can acquire the network information through the first virtual route, so that the network information can be acquired through the first virtual route and information interaction is performed between the first virtual route and other routes, and the problem that various dynamic routing protocols cannot be supported in the prior art is solved; when the first virtual route needs to be deleted, the first virtual route is deleted based on the deletion requirement, and meanwhile the route information of the first virtual route sent by the first host is deleted, so that other hosts or equipment can no longer find the path of the first virtual route, and information interaction through the first virtual route is no longer performed.
The embodiment discloses a virtual network management method, a flowchart of which is shown in fig. 4, and the method includes:
step S41, the first host determines the migration requirement for migrating the first virtual device to the second host;
step S42, the first host deletes the first virtual device on the first host based on a requirement for migrating the first virtual device, and meanwhile, deletes the first virtual route of the first virtual device and the route information of the first virtual route sent by the first host;
step S43, sending the relevant information of the first virtual device to the second host, so that the second host creates a second virtual device, sets a second virtual route on the second virtual device, and sends the route information of the second virtual route, where the relevant information of the second virtual device is the same as the relevant information of the first virtual device.
When the first virtual device needs to be migrated from the first host to the second host, the first host generates a migration requirement of the first virtual device, and then deletes the first virtual device on the first host based on the migration requirement of the first virtual device, deletes the first virtual route of the first virtual device at the same time, and deletes the route path of the first virtual route sent by the first host together.
After the first host deletes the relevant information based on the migration requirement of the first virtual device, the first host sends the relevant information of the first virtual device to the second host, so that the second host creates a second virtual device with the same network information as the first virtual device, sets a second virtual route on the second virtual device, and sends the route information of the second virtual route, so that other hosts or routes except the second host can acquire the route information of the second virtual route, and can perform information interaction with the second virtual route based on the route information of the second virtual route.
The migration requirement for migrating the first virtual device to the second host may be subjectively determined for the first host, or may be determined based on an objectively existing problem of the first host or the first virtual device;
in addition, still include: the method comprises the steps that when a first host determines that a host fails, a migration requirement for migrating a first virtual device to a second host is generated, and at the moment, based on the migration requirement generated by the host failure, the first host does not need to delete routing information of the first virtual device, a first virtual route and the first virtual route, directly creates a related third virtual device and a third virtual route on the second host, and sends the routing information of the third virtual route.
Specifically, the first host sends the relevant information of the first virtual device to the second host based on the host failure, so that the second host creates a third virtual device, sets a third virtual route on the third virtual device, and sends the route information of the third virtual route, where the relevant information of the third virtual device is the same as the relevant information of the first virtual device.
Based on the migration requirement generated by the host fault, the second host directly creates the third virtual device and the third virtual route, and meanwhile, the first host can delete the route information of the first virtual route, so that the route information of the first virtual route sent by the first host is prevented from becoming invalid route information.
The migration requirement generated by the host fault comprises the migration requirement of the first virtual device and the migration requirement of other virtual devices arranged on the first host, namely, all the devices arranged on the first host are migrated to other hosts, so that the problem that information cannot be transmitted on time and efficiently due to the fault of the first host is solved.
In addition, when the first host fails, if the first host cannot send the relevant information of the first virtual device, the mobile edge computing platform can send the relevant information of the first virtual device to the second host, so as to avoid the problem that the information caused by the failure of the first host cannot be accurately transmitted to the host of the virtual device to be migrated.
Further, the first host may migrate the first virtual device corresponding to the first host to another host, and the first host may also obtain the virtual device migrated by the other host.
Specifically, the first host acquires a migration requirement for migrating a fourth virtual device to the first host, the first host acquires related information of the fourth virtual device based on the acquired migration requirement of the fourth virtual device, the first host creates a fifth virtual device based on the related information of the fourth virtual device, sets a fifth virtual route on the fifth virtual device, and sends route information of the fifth virtual route, so that other hosts or routes acquire the route information of the fifth virtual route, and can acquire information of the fifth virtual device through the fifth virtual route based on the route information of the fifth virtual route, wherein the related information of the fifth virtual device is the same as the related information of the fourth virtual device.
When virtual devices on other hosts need to be migrated to the first host, the first host directly creates a fifth virtual device on the basis of the corresponding virtual switch, and sets a fifth virtual route on the fifth virtual device, so that the function and information of the fourth virtual device are realized through the fifth virtual device.
In addition, the fifth virtual device may also be another virtual device that is not in use on the first host, and at this time, a virtual route is set for the other virtual device, and the route information of the virtual route is sent, and the other virtual device that is not in use is directly used, thereby avoiding the problem of resource waste caused by creating the virtual device again.
If the fifth virtual device adopts other virtual devices which are not in use on the first host, the information in the virtual device is not deleted, but a new storage module is directly added on the fifth virtual device for storing and operating the related information on the fourth virtual device, so that the function of the fourth virtual device is realized on the basis of the fifth virtual device, that is, the simultaneous operation of the other virtual devices and the fourth virtual device can be realized.
The virtual network management method disclosed in this embodiment is applied to a mobile edge computing platform, where the mobile edge computing platform at least includes at least one host, a first route connected to the at least one host, and at least one virtual device corresponding to the at least one host, where the at least one host includes at least the first host, the first host determines a migration requirement for migrating the first virtual device to a second host, and the first host deletes the first virtual device on the first host and deletes the first virtual route of the first virtual device and route information of the first virtual route sent by the first host based on the migration requirement of the first virtual device, and sends related information of the first virtual device to the second host, so that the second host creates a second virtual device, sets a second virtual route on the second virtual device, and sends route information of the second virtual route, and the related information of the second virtual device is the same as the related information of the first virtual device. According to the scheme, in the mobile edge computing platform, when the first host determines that the first virtual device needs to be migrated to the second host, the first virtual device, the first virtual route and the route information of the first virtual route are deleted, and the second host is sent with the relevant information value, so that the second host can create the relevant virtual device and the relevant virtual route, the relevant information of the first virtual route is transmitted on the second host, and the problem that the information on the first virtual device cannot be transmitted when the first virtual device on the first host goes wrong is avoided.

After the first virtual route is set by the first host, the route information of the first virtual route is sent out, so that other hosts or routes can acquire the route information of the first virtual route, the first virtual route can be found based on the route information of the first virtual route, and the network information is acquired through the first virtual route.
The routing information of the first virtual route may be: path information of the first virtual route, such as: the first virtual route is specifically set at what position, and is set at the position of the virtual device corresponding to which host.
The first host sends the routing information of the first virtual route, which is not only sent to the mobile edge computing platform, but also issued to all networks except the mobile edge computing platform, so that all routes or hosts in the network can find the first virtual route through the routing information, thereby realizing information interaction.
Specifically, when a virtual route needs to be created at a first virtual device, a first host creates a first virtual route for the first virtual device, and then issues route information of the first virtual route to a network, so that all routes or hosts in the network can find the first virtual route through the route information; and then, the first host acquires the network information through the first virtual route, and after the first host acquires the network information, other hosts or routes need to acquire the network information from the first host through the first route if the other hosts or routes want to acquire the network information, so that all the routes or hosts in the network can acquire the network information except the first virtual route.
Further, the first host may also obtain routing information of the virtual route sent by the other host, that is:
the first host acquires the routing information of the sixth virtual route sent by the third host, and the first host acquires the information on the sixth virtual device based on the routing information of the sixth virtual route, and the sixth virtual route is arranged on the sixth virtual device.
The first host can send the routing information of the first virtual route based on the first virtual route set by the first virtual device, so that other hosts or devices can acquire the information on the first virtual device based on the routing information of the first virtual route; the first host may also send routing information based on virtual routes set on other hosts, such as: and the third host is provided with sixth virtual equipment, creates a corresponding sixth virtual route for the sixth virtual equipment, and then sends out the route information of the sixth virtual route so that other hosts can acquire the information on the third host based on the route information of the sixth virtual route.
The first host acquires the routing information of a sixth virtual route sent by the third host, and if the first host needs to perform information interaction with sixth virtual equipment on the third host, the interaction can be performed based on the sixth virtual route, that is, the information on the first host is sent to the sixth virtual equipment based on the sixth virtual route, or the information on the sixth virtual equipment is sent to the first host or the first virtual equipment on the first host based on the sixth virtual route, so that the interaction between the first virtual equipment and the sixth virtual equipment is realized.
Further, the processor determines a virtual routing setup requirement, comprising:
the processor determines a deletion requirement for deleting a first virtual route set in the first virtual device, deletes the first virtual route set on the first virtual device based on the deletion requirement for deleting the first virtual route set in the first virtual device, and deletes route information of the first virtual route sent by the first host.
The first virtual device corresponding to the first host may set the first virtual route based on the actual usage requirement, or may delete the first virtual route based on the actual usage requirement.
When determining that the network information at the first network address does not need to be acquired by other hosts or routes any more, or the first network address does not need to acquire the relevant information of other hosts or routes any more; or, the first virtual device no longer needs to interact with other hosts or routes, and then determines a deletion requirement, where the deletion requirement is a deletion requirement for deleting the first virtual route set in the first virtual device.
Then, the first host directly deletes the first virtual route set on the first virtual device based on the deletion requirement, and at the same time, deletes the route information of the first virtual route sent by the first host, so as to avoid that when other hosts or routes prepare to acquire information or send information through the route information of the first virtual route, it is detected that no corresponding virtual route exists at the route information of the first virtual route, thereby determining that the route information is invalid route information, which causes waste of communication resources.
Further, the deletion requirement may also be a deletion requirement of the virtual device.
The first host determines a deletion requirement for deleting the first virtual device, deletes the first virtual device and the first virtual route set on the first virtual device based on the deletion requirement for deleting the first virtual device, and deletes the route information of the first virtual route sent by the first host.
When the first host does not need the first virtual device any more, the first host generates a deletion requirement of the first virtual device, executes the deletion requirement of the first virtual device, and deletes the first virtual route set on the first virtual device and the route information of the first virtual route sent by the first host at the same time of deleting the first virtual device, so as to prevent the route information of the first virtual route sent by the first host from becoming invalid route information.
If the first virtual device is deleted, the first virtual route no longer has an existing basis, and therefore, the first virtual route is also deleted at the same time.
Further, the processor determines a virtual routing setup requirement, comprising:
the processor determines a migration requirement for migrating the first virtual device to the second host, deletes the first virtual device on the first host based on the requirement for migrating the first virtual device, and meanwhile deletes a first routing of the first virtual device and routing information of the first virtual routing sent by the first host, and sends related information of the first virtual device to the second host, so that the second host creates the second virtual device, sets a second virtual routing on the second virtual device, and sends routing information of the second virtual routing, wherein the related information of the second virtual device is the same as the related information of the first virtual device.
When the first virtual device needs to be migrated from the first host to the second host, the first host generates a migration requirement of the first virtual device, and then deletes the first virtual device on the first host based on the migration requirement of the first virtual device, deletes the first virtual route of the first virtual device at the same time, and deletes the route path of the first virtual route sent by the first host together.
After the first host deletes the relevant information based on the migration requirement of the first virtual device, the first host sends the relevant information of the first virtual device to the second host, so that the second host creates a second virtual device with the same network information as the first virtual device, sets a second virtual route on the second virtual device, and sends the route information of the second virtual route, so that other hosts or routes except the second host can acquire the route information of the second virtual route, and can perform information interaction with the second virtual route based on the route information of the second virtual route.
The migration requirement for migrating the first virtual device to the second host may be subjectively determined for the first host, or may be determined based on an objectively existing problem of the first host or the first virtual device;
in addition, still include: the method comprises the steps that when a first host determines that a host fails, a migration requirement for migrating a first virtual device to a second host is generated, and at the moment, based on the migration requirement generated by the host failure, the first host does not need to delete routing information of the first virtual device, a first virtual route and the first virtual route, directly creates a related third virtual device and a third virtual route on the second host, and sends the routing information of the third virtual route.
Specifically, the first host sends the relevant information of the first virtual device to the second host based on the host failure, so that the second host creates a third virtual device, sets a third virtual route on the third virtual device, and sends the route information of the third virtual route, where the relevant information of the third virtual device is the same as the relevant information of the first virtual device.
Based on the migration requirement generated by the host fault, the second host directly creates the third virtual device and the third virtual route, and meanwhile, the first host can delete the route information of the first virtual route, so that the route information of the first virtual route sent by the first host is prevented from becoming invalid route information.
The migration requirement generated by the host fault comprises the migration requirement of the first virtual device and the migration requirement of other virtual devices arranged on the first host, namely, all the devices arranged on the first host are migrated to other hosts, so that the problem that information cannot be transmitted on time and efficiently due to the fault of the first host is solved.
In addition, when the first host fails, if the first host cannot send the relevant information of the first virtual device, the mobile edge computing platform can send the relevant information of the first virtual device to the second host, so as to avoid the problem that the information caused by the failure of the first host cannot be accurately transmitted to the host of the virtual device to be migrated.
Further, the first host may migrate the first virtual device corresponding to the first host to another host, and the first host may also obtain the virtual device migrated by the other host.
Specifically, the first host acquires a migration requirement for migrating a fourth virtual device to the first host, the first host acquires related information of the fourth virtual device based on the acquired migration requirement of the fourth virtual device, the first host creates a fifth virtual device based on the related information of the fourth virtual device, sets a fifth virtual route on the fifth virtual device, and sends route information of the fifth virtual route, so that other hosts or routes acquire the route information of the fifth virtual route, and can acquire information of the fifth virtual device through the fifth virtual route based on the route information of the fifth virtual route, wherein the related information of the fifth virtual device is the same as the related information of the fourth virtual device.
When virtual devices on other hosts need to be migrated to the first host, the first host directly creates a fifth virtual device on the basis of the corresponding virtual switch, and sets a fifth virtual route on the fifth virtual device, so that the function and information of the fourth virtual device are realized through the fifth virtual device.
In addition, the fifth virtual device may also be another virtual device that is not in use on the first host, and at this time, a virtual route is set for the other virtual device, and the route information of the virtual route is sent, and the other virtual device that is not in use is directly used, thereby avoiding the problem of resource waste caused by creating the virtual device again.
If the fifth virtual device adopts other virtual devices which are not in use on the first host, the information in the virtual device is not deleted, but a new storage module is directly added on the fifth virtual device for storing and operating the related information on the fourth virtual device, so that the function of the fourth virtual device is realized on the basis of the fifth virtual device, that is, the simultaneous operation of the other virtual devices and the fourth virtual device can be realized.
