As shown in FIG. 3, it is a flowchart of an embodiment of a configuration method provided by the present application, and the method includes:

Step 301: The first device receives a first configuration request message sent by the second device.

The first device and the second device are both network devices in an N-layer network device, and the first device is a network device that manages the second device in a network device at an upper layer of the second device. The first device may be a top-level network device in an N-tier network device, and the second device may be a layer-2 network device. For example, the first device is the SDN controller in FIG. 1 , and the second device is the BAA1 in FIG. 1 . Alternatively, the first device may also be a middle-layer network device, and the second device is a network device managed by the first device among the next-layer network devices of the first device. For example, the first device is BAA1 in FIG. 1 , and the second device is PNF1 in FIG. 1 .

Step 302, the first device determines the level where the second device is located.

In a possible implementation manner, the second device may carry the second indication information of the level where the second device is located in the first configuration request message, so that the first device may determine the level where the second device is located according to the second indication information .

Or, in another possible implementation manner, the configuration request message received by any one of the N-layer network devices may be set to be sent by the next-layer network device of the network device. Therefore, after receiving the first configuration request message sent by the second device, the first device can determine that the second device is the next-layer network device of the first device, so as to determine the location of the second device based on the level of the first device. level.

Step 303, the first device generates first configuration information according to the level where the second device is located, the first configuration information includes first management information and second management information, the first management information is used to configure the first device, and the second management information is the first management information. Management information of each layer below the level where the second device is located, wherein the second management information is used by the second device to allocate management information to the network devices managed by the second device among the network devices of the next layer of the second device.

In the present application, the first device is pre-configured with management information of the level where the second device is located and the management information of each level below the level where the second device is located. The first device may allocate the first management information to the second device from the management information of the layer where the second device is located, and determine the management information of all layers below the layer where the second device is located as the second management information.

Step 304, the first device sends the first configuration information to the second device.

After the second device receives the first configuration information, it can complete the configuration of the first device according to the first management information in the first configuration information, and preconfigure the second management information in the first device, so as to facilitate the subsequent configuration of the first device. The network device managed by the second device among the network devices at the next layer of the second device allocates management information.

In this application, the top-level network device in the N-layer network device is configured with management information of the N-layer network device. The management information of the N-layer network device includes the management information of the top-level network device (ie, the management information of the first layer) and the management information of the remaining layers (ie, the second layer, the third layer, ..., the Nth layer).

Then, when the first device is a top-level network device, based on FIG. 3 , as shown in FIG. 4 , the above step 303 may specifically be:

Step 303a, the first device allocates the first management information to the second device according to the management information of the level where the second device is located in the management information of the N-layer network device.

That is, the second device is at layer 2, then the first device can allocate management information for configuring the second device to the second device from the layer 2 management information pre-configured in the first device, that is, the first management information.

Step 303b, the first device determines the second management information in the management information of the N-layer network device according to the layer where the second device is located.

The first device determines, according to the layer where the second device is located, the management information of the third layer, ..., the Nth layer as the second management information.

Step 303c, the first device generates first configuration information according to the first management information and the second management information.

In a possible implementation manner, the N-layer network device implements the configuration of the network device through a dynamic host configuration protocol (dynamic host configuration protocol, DHCP). Based on this implementation manner, the above-mentioned first configuration request message may specifically be a DHCP request (DHCP Request) message, which is used to request the configuration of management information such as management IP (management IP) and authentication information. The first configuration information may specifically be option (option) information in DHCP.

The following is an exemplary description of the process of the layer 2 network device requesting configuration from the top-level network device with reference to DHCP and the schematic diagram of the local architecture of the N-layer network device shown in FIG. 5 .

As shown in Figure 5, the network device 1 of the first layer is the management device of the network device 2 of the second layer, the network device 2 of the second layer is the management device of the network device 3 of the third layer, and so on. The network device N-1 of the 1st layer is a management device of the network device N of the Nth layer. Network device 1 is a top-level network device, network device 2 to network device N-1 are middle-layer network devices, and network device N is a bottom-layer network device.

The network device 1 is configured with management information of the N-layer network device, including the management information of the network device 1 and the management information of the remaining layers (ie, the second layer, the third layer, ..., the Nth layer).

Suppose, the management information of the pre-configured layer 2, layer 3, ..., layer N in the network device 1 is:

Network Layers: N-1

Management Info Layer 2: subnet (subnet) 192.168.0.0 netmask (subnet mask) 255.255.0.0 {range (range) 192.168.2.1 192.168.2.111;}

Management Info Layer 3: subnet 192.168.0.0netmask 255.255.0.0{

range 192.168.3.1 192.168.3.111; }

Management Info Layer 4: subnet 192.168.0.0netmask 255.255.0.0{

range 192.168.4.1 192.168.4.111; }

…

Management Info Layer N: subnet 192.168.0.0netmask 255.255.0.0{

range 192.168.N.1 192.168.N.111; }

The number of network layers represents the number of network layers below the layer where the network device 1 is located, that is, there are N-1 layers below the first layer.

When network device 2 requests configuration from network device 1 , network device 2 sends DHCP request message 1 to network device 1 . The network device 1 determines that the network device 2 is a layer 2 network device, and allocates management information to the network device 2 from preconfigured layer 2 management information (ie, management information recorded in the management information layer 2). That is, the network device 1 allocates a management IP (Management IP) to the network device 2 according to the address range allowed by the layer 2 management information (ie, between 192.168.2.1 and 192.168.2.111). It is assumed that the management IP assigned by the network device 1 to the network device 2 is 192.168.2.2. Therefore, the management information 1 assigned by the network device 1 to the network device 2 is 192.168.2.2.

The network device 1 determines that the management information recorded in the management information layer 3 to the management information layer N is the management information 2 . The network device 1 generates option information 1 according to the management information 1 and the management information 2 .

In this example, the option information generated by network device 1 may be:

Option: (XX) Management Info (management information)

Length: XXX

Management IP: 192.168.2.2

Sub Network Layers: N-2

Sub Management Info Layer 3: subnet 192.168.0.0netmask255.255.0.0{

range 192.168.3.1192.168.3.111; }

Sub Management Info Layer 4: subnet 192.168.0.0netmask 255.255.0.0{

range 192.168.4.1192.168.4.111; }

…

Sub Management Info Layer N: subnet 192.168.0.0netmask 255.255.0.0{

range 192.168.N.1192.168.N.111; }

In option information 1, the number of network layers below the layer where the network device 2 is located is indicated by the number of sub-network layers, and the management information layer is indicated by the sub-management information layer as management information of a layer below the layer where the network device 2 is located.

After the network device 2 receives the configuration information 1, it can configure itself according to the management information 1, that is, set the management IP of the network device 2 to 192.168.1.2. And according to the management information 2, the management information of the third layer, .

It can be understood that, based on the example shown in FIG. 5 , when the first device is network device 1 and the second device is network device 2, the first configuration request message in step 301 is the above-mentioned DHCP request message 1, and step 303 The first configuration information in is the above-mentioned configuration information 1, the first management information is the above-mentioned management information 1, and the second management information is the above-mentioned management information 2.

When the first device is a middle-layer network device, the first device needs to request the management device of the first device for management information for configuring the first device, as well as the management information of the layer where the second device is located and the layers below the layer where the second device is located. management information. That is, as shown in FIG. 6 with reference to FIG. 3 , before the above step 301, the method further includes:

Step 300a, the first device sends a second configuration request message to the third device.

The third device is a network device in an N-layer network device, and the third device is a network device that manages the first device in a network device at an upper layer of the first device.

Step 300b, the first device receives the second configuration information sent by the third device, the second configuration information includes third management information and fourth management information, the third management information is used to configure the first device, and the fourth management information is the third management information. The management information of each layer below the layer where a device is located, and the fourth management information is used by the first device to allocate management information to the network devices managed by the first device among the network devices of the next layer of the first device.

After the first device applies for the second configuration information from the third device, it can complete the configuration of the first device according to the third management information, and learn the management information of each layer below the layer where the first device is located. For example, assuming that the first device is a layer 2 network device, the fourth management information applied by the first device to the third device includes management information of layers 3 to N. The first device may pre-configure the fourth management information in the first device, so that when a network device managed by the first device among the network devices in the next layer of the first device, the first device can provide the network device according to the fourth management information. Assign management information.

As shown in FIG. 6 , when the first device is a middle-layer network device, the foregoing step 303 may specifically be:

Step 303d, the first device determines the first management information and the second management information according to the level where the second device is located and the fourth management information.

The fourth management information includes management information of the layer where the second device is located and management information of each layer below the layer where the second device is located. The first device allocates the first management information to the second device from the management information of the layer where the second device is located, and determines the management information of all layers below the layer where the second device is located as the second management information.

Step 303e, the first device generates first configuration information according to the first management information and the second management information.

Exemplarily, assuming that the first device is a layer 2 network device, the third device is a top-level network device, and the second device is a layer 3 network device managed by the first device. For example, with reference to the example shown in FIG. 4 , when the first device is network device 2 and the third device is network device 1, the first configuration request message in step 300a is the above DHCP request message 1, and the second configuration request message in step 300b The configuration information is the above-mentioned configuration information 1, the third management information is the above-mentioned management information 1, and the fourth management information is the above-mentioned management information 2.

After the network device 2 completes the application for configuration, the management IP of the network device 2 is set to 192.168.2.2 according to the configuration information 1 in the option information. The configuration information 1 is then preconfigured in the network device 2 .

After the pre-configuration is completed, the management information of the pre-configured layer 3, ..., layer N in the network device 2 is:

Network Layers: N-2

Management Info Layer 3: subnet 192.168.0.0netmask 255.255.0.0{

range 192.168.3.1 192.168.3.111; }

Management Info Layer 4: subnet 192.168.0.0netmask 255.255.0.0{

range 192.168.4.1 192.168.4.111; }

…

Management Info Layer N: subnet 192.168.0.0netmask 255.255.0.0{

range 192.168.N.1 192.168.N.111; }

When the network device 3 requests the network device 2 for configuration, the network device 3 sends the DHCP request message 2 to the network device 2 . The network device 2 determines that the network device 3 is a layer 3 network device, and allocates management information to the network device 3 from preconfigured layer 3 management information (ie, management information recorded in the management information layer 3). That is, the network device 2 allocates a management IP to the network device 3 according to the address range (ie, between 192.168.3.1 and 192.168.3.111) that is allowed to be allocated by the layer 3 management information. It is assumed that the management IP assigned by the network device 1 to the network device 2 is 192.168.3.13. Therefore, the management information 3 assigned by the network device 2 to the network device 3 is 192.168.3.13.

Then, the network device 3 determines the management information recorded in the management information layers 4 to N (ie, the network information from the fourth to the Nth layers preconfigured in the network device 2 ) as the management information 4 . The network device 2 generates option information 2 according to the management information 3 and the management information 4 .

In this example, the option information generated by the network device 2 may be:

Option: (XX) Management Info

Length: XXX

Management IP: 192.168.3.13

Sub Network Layers: N-3

Sub Management Info Layer 4: subnet 192.168.0.0netmask 255.255.0.0{

range 192.168.4.1192.168.4.111; }

…

Sub Management Info Layer N: subnet 192.168.0.0netmask 255.255.0.0{

range 192.168.N.1192.168.N.111; }

After the network device 3 receives the configuration information 2, it can configure itself according to the management information 2, that is, set the management IP of the network device 3 to 192.168.3.13. And according to the management information 4, the management information of the fourth layer, .

Then, based on the example shown in FIG. 5 , when the first device is network device 2 and the second device is network device 3, the first configuration request message in step 301 is the above DHCP request message 2, and the first configuration request message in step 303 is the above DHCP request message 2. One configuration information is the above-mentioned configuration information 2 , the first management information is the above-mentioned management information 3 and the second management information is the above-mentioned management information 4 .

It can be understood that, in the configuration method provided by this application, by pre-configuring the management information of the N-layer network device in the top-level network device, when the second-layer network device applies to the top-level for configuration, the top-level network device is not only a layer-2 network device. In addition to the management information allocated by the network device, the management information of the third layer, ..., and the Nth layer will also be delivered at the same time, so as to be pre-configured in the network device of the second layer. When layer 3 network devices apply for configuration to layer 2 network devices, in addition to allocating management information to layer 3 network devices, layer 2 network devices will also deliver layer 4, ..., Nth Layer management information to be preconfigured in Layer 3 network devices. And so on, until the network device of the Nth layer completes the application configuration. Thus, the configuration of the N-layer network equipment is automatically completed through one-time manual configuration, the steps of manual deployment are reduced, and the efficiency of automatic configuration of network deployment is improved.

In an example, the N-layer network equipment will be randomly expanded according to user needs. For example, in the network architecture shown in Figure 1, it is necessary to add a VNF at layer 3, or add a BBA at layer 2, etc. With the expansion of N-layer network devices, the initially pre-configured management information may be insufficient. For example, BAA1 initially requested 100 management IPs from the SDN controller for allocation to 100 VNFs and/or PNFs in Layer 3 that are managed by BBA1. But when BAA1 expands to the 101st VNF or PNF, there will be no remaining management IP in BAA1 that can be assigned to this VNF or PNF.

As shown in FIG. 7 , when the first device is an intermediate layer network device, the method further includes:

Step 701, the fourth device sends a third configuration request message to the first device.

Wherein, the fourth device may be a network device extended in the N-layer network device, and the first device is a network device that manages the second device in the upper-layer network device of the fourth device.

The fourth device sends a third configuration request message to the first device to request the first device to allocate management information.

Step 702, the first device determines the level where the fourth device is located.

Step 703, when the management information of the level where the pre-configured fourth device is located is used, the first device sends a fourth configuration request message to the third device, and the fourth configuration request message carries first indication information, the first indication information It is used to indicate the management information that needs to be added at the level where the fourth device is located.

After receiving the third configuration request message, the first device may search for unallocated management information in the management information of the level where the pre-configured fourth device is located. If all the management information of the level where the pre-configured fourth device is located is used, the first device may determine that it needs to apply for adding management information of the level where the fourth device is located (ie, the layer below the level where the first device is located). The first device may send a configuration request message to the third device to request the third device to allocate the added management information.

The fourth configuration request message may be a configuration request message obtained after the first device modifies the third configuration request message, such as encapsulating the management IP of the first device for the third configuration request message, adding first indication information, and the like.

The management information applied for by the first device to be added may be a preset amount of management information. For example, if a fourth device currently applies to the first device for a management IP, the first device may apply to the third device to add 100 management IPs to the level where the fourth device is located. One can be allocated to the fourth device, and the rest can be pre-configured in the first device for subsequent expansion.

Step 704: The first device receives third configuration information sent by the third device, where the third configuration information carries the added management information.

The third device may be a top-level network device or a middle-level network device.

If the third device is a top-level network device, then the first device is a layer-2 network device, and the fourth device is a layer-3 network device. The third device is pre-configured with extended management information of the N-layer network device, including management information that allows expansion of each layer. The third device may determine, according to the first indication information, that management information needs to be added to Layer 3. The third device determines the added management information for the third layer, and then carries the added management information in the third configuration information and sends it to the first device.

The management information added by the third device for layer 3 may be all preconfigured extended management information of layer 3. For example, the third device is pre-configured with 200 pieces of extended management information of layer 3, that is, the address range of the extended management IP from 192.168.3.112 to 192.168.3.312. The third device may carry all the 200 management IPs in the third configuration information and send it to the first device.

If the number of management information to be added is indicated in the first indication information, the third device may allocate extended management information according to the number indicated by the first indication information. For example, if the first indication information indicates that 100 management IPs need to be added, the third device may carry 192.168.3.112 to 192.168.3.212 in the third configuration information and send it to the first device.

If the third device is an intermediate layer network device, for example, the third device is a layer 2 network device, the first device is a layer 3 network device, and the fourth device is a layer 4 network device. After receiving the fourth configuration request message sent by the first device, the third device determines that the third device requests to add management information for layer 4. The third device may encapsulate the management IP of the third device in the fourth configuration request message, and send it to the top-level network device, and the top-level network device divides the extended management information of the third layer. After receiving the third configuration information sent by the top-level network device, the third device forwards the third configuration information to the first device.

Step 705, the first device allocates fifth management information to the fourth device from the added management information.

The first device assigns fifth management information to the fourth device from the added management information. For example, the increased address range carried in the third configuration information is 192.168.3.112 to 192.168.3.312, then the first device may allocate one from the increased address range to the fourth device, for example, the address 192.168.3.112 is allocated. That is, the fifth management information allocated by the first device to the fourth device is management IP 192.168.3.112.

The first device preconfigures the remaining management information, for example, the address range is 192.168.3.113 to 192.168.3.312, in the first device, so that the management information can be divided into other extended management devices subsequently.

Step 706, the first device sends fifth management information to the fourth device.

After receiving the fifth management information, the fourth device uses the fifth management information to complete the configuration of the fourth device.

It is worth noting that, when expanding the N-layer network device, the configuration method provided by this application is adopted, and the extended management information of the N-layer network device is preset in the top-level network device, so that the automatic configuration of the expanded network device can be realized. There is no need to perform manual configuration every time a network device is expanded, which reduces the steps of manual deployment and improves the efficiency of automatic configuration of network deployment.
