In order to make those skilled in the art better understand the technical solutions provided in the embodiments of the present application and make the above objects, features and advantages of the embodiments of the present application more obvious and understandable, a description is first given below of a method for allocating an IP address according to the related art.
Referring to fig. 1, the process may include the following steps:
The flow shown in fig. 1 is thus completed.
Through the method flow shown in fig. 1, it may be implemented that the SDN controller allocates a management IP address to the network device to be managed, but the management IP address allocated to the network device to be managed by the SDN controller may conflict with IP addresses of other network devices (such as LoopBack addresses or dynamic IP addresses), and in the case of a conflict, if the network device to be managed configures a conflicting management IP address, an error may occur in a process of establishing a control channel with the network device to be managed by the SDN controller using the management IP address.
In order to solve the problems in the allocation method for managing IP addresses provided by the related art, an embodiment of the present application provides an automatic allocation method for managing IP addresses, and the following describes the technical solution in the embodiment of the present application in further detail with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a flowchart of an automatic allocation method for managing IP addresses according to an embodiment of the present disclosure. As an embodiment, the flow illustrated in fig. 2 may be applied to an SDN controller.
As shown in fig. 2, the process may include the following steps:
First, in this embodiment of the present application, in order to facilitate maintenance of resources of a management IP address pool, four states of management IP addresses are set for a case where each management IP address in the management IP address pool is currently allocated and used: the method comprises the steps of allocating unused, used, unused and used resources, and adding a page for displaying the state of each management IP address in a management IP address pool on a display interface of gateway software for managing the network equipment by an SDN controller so as to check the resource use condition of the management IP address pool.
If the current state of one management IP address is unallocated and unused, the management IP address is not allocated to any network equipment and is not used by any network equipment currently, wherein the use refers to that the management IP address is configured on the network equipment, and the network equipment can communicate with the outside by using the management IP address; if the current state of a management IP address is unallocated already-used, it indicates that the management IP address is already used by a network device, but the same IP address on the network device as the management IP address is not allocated by the SDN controller. The meaning of other two states of the management IP address can refer to the meaning of unused unallocated and used unallocated, which are not described in detail here.
Further, if the status of the management IP address is checked as being used without allocation, this means that the management IP address may be a management IP address of a network device managed manually, or may be an IP address (such as a LoopBack address, or a dynamic IP address) of a network device in the SDN network that is not managed but has an address conflict with the management IP address. If there is an IP address in the network device with an address conflict, since the network device does not configure a management IP address but configures another IP address that is the same as the management IP address, it is necessary to manually process the management IP address configuration of the network device and establish a control channel with the SDN controller to manage the network device.
Based on the four states of the management IP address, in this embodiment of the application, if the SDN controller receives a management IP address allocation request message sent by a network device to be managed, a management IP address that is currently in an unallocated state and is not used for allocation may be found from a database storing management IP address pool resources, where the database storing management IP address pool resources may be set on the SDN controller or on another device independent of the SDN controller.
As an embodiment, if the SDN controller receives the management IP address allocation request message, the SDN controller may sequentially detect the states of the management IP addresses stored in the management IP address pool from the large to the small directions according to the management IP addresses, find a management IP address whose state is not allocated and unused, use the management IP address whose state is not allocated and unused as the management IP address to be allocated to the network device, stop detecting the state of the management IP address stored in the management IP address pool, and start performing collision detection on the management IP address.
It should be noted that, here, the size of the management IP address is related to the numerical value for managing the IP address, and the larger the numerical value for managing the IP address is, the larger the management IP address is; the smaller the value for managing the IP address, the smaller the management IP address.
As another embodiment, if the SDN controller receives the management IP address allocation request message, it may also find out all the management IP addresses in the management IP address pool that are not allocated and unused, randomly select one management IP address from all the management IP addresses that are not allocated and unused, serve as the management IP address to be allocated to the network device, and perform collision detection on the management IP address.
In a specific implementation, if the management IP address status is unallocated and unused, it indicates that the SDN controller does not allocate a management IP address to any network device, and no network device currently managed by the SDN controller uses the management IP address, but a LoopBack address or a dynamic IP address configured by a network device that is not managed in the SDN network may conflict with the management IP address. Therefore, the embodiment of the application performs conflict detection on the management IP address to be allocated to the network device to ensure that the management IP address allocated to the network device is available.
Optionally, in this step 202, detecting whether the management IP address conflicts with an IP address allocated to an existing network device in the SDN network, may be implemented in the following manner: sending a ping packet to a management IP address, if a response of the ping packet is received within a specified time, determining that the management IP address conflicts with an IP address allocated to the existing network equipment in the SDN, and if the response of the ping packet is not received within the specified time, determining that the management IP address does not conflict with the IP address allocated to the existing network equipment in the SDN.
In the embodiment of the application, after the management IP address is allocated to the network device, if it is known that the network device detects that the allocated management IP address does not conflict with the LoopBack address or the dynamic IP address of other network devices, the state of the management IP address in the management IP address pool is updated from allocated unused to allocated used; if it is known that the network device detects that the allocated management IP address conflicts with the LoopBack address or the dynamic IP address of other network devices, the state of the management IP address in the management IP address pool is updated from allocated unused to unallocated used.
In specific implementation, the SDN learns whether the network device detects that the allocated management IP address conflicts with a LoopBack address or a dynamic IP address of another network device, and may determine, according to a conflict detection result of the management IP address reported by the network device after the management IP address is allocated to the network device to be managed.
It should be noted that, as an embodiment, in order to allocate a management IP address to a Network device to be managed, an SDN controller may create a temporary connection with the Network device according to a dynamic IP address configured on the Network device to be managed based on a specified Protocol (e.g., a Network Configuration Protocol), where the SDN controller may allocate the management IP address and a collision detection result of the Network device reporting the management IP address, where the SDN controller may implement the temporary connection, and if the SDN controller knows that the Network device detects that there is no address collision in the management IP address, the SDN controller may establish a control channel with the Network device by using the management IP address, implement management of the Network device, and destroy the created temporary connection.
As for how the network device detects whether the allocated management IP address conflicts with the LoopBack address or the dynamic IP address of other network devices, reference may be made to the related description in the method flow shown in fig. 4, which is not described herein again.
Optionally, after the step 204, the step of finding a management IP address which is not allocated and unused from the management IP address pool in the step 201 may be returned, and a management IP address which is not allocated and unused is found again, and the steps 201 to 204 are repeated to allocate a management IP address to the network device to be managed; or, if after this step 204, an unused management IP address is not found to be not allocated in the state, which indicates that there is no management IP address that can be allocated to the network device to be managed in the current SDN controller, the process of allocating a management IP address to the network device to be managed may be ended. This is only one implementation step provided by the present application, and optionally, after step 204, the process of allocating a management IP address to a network device to be managed may also be directly ended, and the content executed after step 204 is not limited in the present application.
At this point, the flow shown in fig. 2 is completed.
As can be seen from the process shown in fig. 2, in response to allocating a management IP address to a network device to be managed, an SDN controller may automatically find a management IP address that is not allocated and unused from a management IP address pool, perform conflict detection on the management IP address, and allocate the management IP address to the network device to be managed without a conflict, without manually allocating the management IP address to the network device, thereby simplifying the allocation operation of the management IP address, improving the allocation efficiency of the management IP address, and avoiding an error occurring in the process of establishing a control channel between the management IP address and the SDN controller by the network device.
The above examples are merely for convenience of understanding, and the embodiments of the present application are not particularly limited.
It should be noted that, in the embodiment of the present application, in a case that the SDN controller is not required to manage the network device, the managed network device may be deleted, and a state of a management IP address used by the managed network device in the management IP address pool is updated from allocated used state to unallocated unused state, so as to implement recovery of the management IP address.
Illustratively, the SDN controller may be triggered to send a message for deleting the management IP address to the network device by selecting, on the network management software, to delete the management relationship with the network device, and the management IP address may be reused by deleting the correspondence between the management IP address and the network device recorded in the SDN controller.
Referring to fig. 4, fig. 4 is a flowchart of another method for automatically allocating an IP address according to the embodiment of the present application. The flow shown in fig. 4 may be applied to a network device as one embodiment. The network device is a network device to be managed by the SDN controller.
As shown in fig. 4, the process may include the following steps:
In this embodiment of the application, if the state of the management IP address is allocated and not used, it indicates that the management IP address is currently allocated to the network device by the SDN controller, but the network device does not configure the management IP address to communicate with the SDN controller.
In specific implementation, the detailed process that the SDN controller allocates to the management IP address of the network device in the method flow shown in fig. 2 may be referred to in the specific acquiring process of the management IP address received in step 401, and is not described herein again.
Optionally, in order to respond to receiving a management IP address allocated to the network device by the SDN controller, in this step 401, it is detected whether the management IP address conflicts with a LoopBack address or a dynamic IP address of another network device, where the conflict detection may be specifically implemented in multiple ways, and the application does not limit this:
as an embodiment, a ping packet may be sent to the management IP address, and if a response of the ping packet is received within a specified time, it is determined that the management IP address conflicts with the loop back address LoopBack address or the dynamic IP address of the other network device, and if a response of the ping packet is not received within the specified time, it is determined that the management IP address does not conflict with the loop back address LoopBack address or the dynamic IP address of the other network device.
As another embodiment, an ARP (Address Resolution Protocol) request carrying a management IP Address may be broadcasted in a network where the network device is located, and if an ARP response of the ARP request is received within a specified time, it is determined that the management IP Address conflicts with a LoopBack Address or a dynamic IP Address of another network device, and if an ARP response of the ARP request is not received within the specified time, it is determined that the management IP Address does not conflict with a LoopBack Address or a dynamic IP Address of another network device.
And step 402, if not, establishing a control channel with the SDN controller by using the management IP address so that the SDN controller manages the network device through the control channel.
In the embodiment of the application, if it is detected that a received management IP address does not conflict with a LoopBack address or a dynamic IP address of other network equipment, sending a message indicating that the management IP address does not conflict to an SDN controller, so that the SDN controller updates the state of the management IP address in a management IP address pool from allocated unused to allocated used; if the management IP address is detected to conflict with the LoopBack address LoopBak address or the dynamic IP address of other network equipment, sending a message for indicating the management IP address conflict to the SDN controller so as to update the state of the management IP address in the management IP address pool from allocated unused to unallocated used. In this embodiment, the network device may send a message to the SDN controller through a temporary connection established between the network device and the SDN controller based on the configured dynamic IP address.
Further, if the SDN controller receives a message indicating that the management IP address does not conflict, the SDN controller may initiate a request for establishing a control channel to the network device based on the management IP address, so that the SDN controller may manage the network device through the established control channel. Here, after the SDN controller establishes a control channel with a network device, the network device will become a network device managed by the SDN controller.
It should be noted that the embodiment of the present application can be applied to the architecture of a spine-leaf-access three-layer network as shown in fig. 3. In a scenario where an SDN controller is used to manage network devices in a spine-leaf-access three-layer network, a network device to be managed in this embodiment may be any one of a spine device, a leaf device, and an access device. In the network architecture, the spine device and the leaf device are three-layer network devices, the spine device and the leaf device are configured with a LoopBack address and a dynamic IP address before being managed, the access device is a two-layer network device, and the access device is configured with the dynamic IP address before being managed. In the network architecture, the LoopBack addresses configured by the spine device and the leaf device are used for realizing routing planning of the SDN network, and the dynamic IP addresses configured on the three network devices can be used for establishing temporary connection with the SDN controller. The specific configuration process of the LoopBack address and the dynamic IP address can refer to the related art, and is not described herein again.
For different network devices, in the embodiment of the present application, when it is determined that the management IP address does not conflict with the LoopBack address or the dynamic IP address of other network devices, the manner of configuring the management IP address is different.
As an embodiment, a management IP address is configured for a spine device or a leaf device, and the management IP address needs to be configured to a VSI (Virtual Switch Interface) Virtual Interface set on the spine device or the leaf device; and configuring a management IP address for the access device requires configuring the management IP address to a VLAN virtual interface set on the access device.
Further, if the managed network device in the embodiment of the present application receives a message sent by the SDN controller to delete a management IP address, the management IP address configured at the VSI virtual interface or the VLAN virtual interface of the network device is deleted.
The flow shown in fig. 4 is completed.
As can be seen from the flow shown in fig. 4, the network device to be managed may automatically perform collision detection on the management IP address allocated to the network device by the SDN controller, and establish a control channel with the SDN controller by using the management IP address when there is no collision. By the method and the device, the allocation operation of the management IP address can be simplified, the allocation efficiency of the management IP address is improved, and errors of the network equipment in the process of establishing the control channel by using the management IP address and the SDN controller are avoided.
