Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
For convenience of explanation, a part of the concept related to the present disclosure will be explained first.
The network management software is used for deploying the Underlay network, and is, for example, a Director.
The VCFC is a Software Defined Network (SDN) controller, and is used for implementing deployment and management of an Overlay Network.
The network element devices may include a root node (Spine node) and a Leaf node (Leaf node). The Spine node may be connected to a management switch. The Leaf node can be connected with the management switch and also can be connected with the Spine node. The Access node (Access device) may be connected to the Leaf node, and the Access node is, for example, a user side server or a terminal.
Fig. 1 is a schematic diagram of a VCF network, which includes network management software, VCFC, a management switch, root nodes 1 to 3, leaf nodes 1 to 3, and user side servers 1 to 6, as shown in fig. 1. Leaf nodes 1 to 3 are connected to root nodes 1 to 3 (and may also be connected to the management switch), customer-side servers 1 to 2 are connected to the leaf node 1, customer-side servers 3 to 4 are connected to the leaf node 2, and customer-side servers 5 to 6 are connected to the leaf node 3.
The VCF network shown in fig. 1 includes only one management switch, however, it should be noted that a plurality of management switches may be included in the VCF network, and the VCF network shown in fig. 1 is only one example of the VCF network.
The process of network management software deployment of the Underlay network is as follows: the network management software plans and deploys the VCF network, so that the configuration file of the network element equipment corresponding to the role is generated according to the role of the network element equipment. When the network element device is powered on and on line, the network element device obtains its own management IP address from a Dynamic Host Configuration Protocol (DHCP) Server (Server), and obtains a Configuration file of the network element device corresponding to its role generated by network management software according to its role. The network element device generates first configuration information of its own Underlay network through a local automation program, where the first configuration information includes a VXLAN Tunnel End Point (VTEP) IP address of the network element device and a system name of the network element device.
The network element device generates its own VTEP IP address according to its own management IP address or its own Media Access Control (MAC) address. The network element device generates its own system name according to its own management IP address and its own role, for example, the last two bits of the management IP address of the role _ network element device of the network element device are used as the system name of the network element device. Illustratively, the system name of the network element device is Leaf _1.34, where Leaf is the role of the network element device, and 1.34 is the last two bits of the management IP address of the network element device.
Since the VCFC needs to deploy the Overlay network according to the management IP address of the network element device and the second configuration information of the network element device, such as the network element name, the VTEP IP address, the device type, the Virtual Distributed Switch (VDS) where the device is located, and the like, the VCFC itself cannot determine the management IP address of the network element device and the second configuration information of the network element device, and therefore an administrator needs to manually input the management IP address of the network element device and the second configuration information of the network element device on the VCFC.
It should be noted that, if the device type is Leaf, the second configuration information further includes a mapping relationship between VLAN (Virtual LAN) and VXLAN (Virtual Extensible LAN).
Therefore, before the Overlay network is deployed through the VCFC, an administrator needs to manually configure the management IP address of the network element device and the second configuration information of the network element device on the VCFC, and the VCF network deployment is inconvenient.
Embodiments of the present disclosure are described in detail below with reference to the drawings.
Fig. 2 is a flowchart illustrating a configuration delivery method according to an example embodiment. The configuration issuing method can be applied to network management software in a VCF network. As shown in fig. 2, the configuration issuing method may include the following steps.
In step S220, a management switch in the VCF network is brought into management, and a corresponding relationship between an interface of the management switch for connecting the network element device in the VCF network and the configuration information of the network element device is recorded.
In this embodiment, a management interface of any one network element device in the VCF network may be connected to an interface of the management switch, and the management switch may determine an interface of the network element device to which the management switch is connected according to a message exchanged with the network element device. For example, when the first interface of the management switch receives a message for applying for managing an IP address sent by the network element device, the management switch can determine that its own first interface is connected to the network element device according to the message.
Compared with the prior art in which the management switch is not brought into management by the network management software, in the embodiment, the management switch in the VCF network is brought into management by the network management software. On this basis, the network management software can record the corresponding relation between the interface of the management switch connected with the network element equipment and the configuration information of the network element equipment.
In one possible implementation, the configuration information may include: the address of the controller, the name of the network element, the VTEP IP address, the type of the device, the VDS where the device is located, the mapping relation of VLAN-VXLAN, etc. Wherein, the network element name, the device type, the VDS where the device is located, and the VLAN-VXLAN mapping relationship are the second configuration information, and the VTEP IP address is the common configuration information of the first configuration information and the second configuration information.
Illustratively, the network management software may record the correspondence shown in table 1 below.
Table 1 management of correspondence between interfaces of a switch connecting network element devices and configuration information of the network element devices
Interface for managing switch connecting network element equipment Configuration information of network element equipment
port 1 Configuration information 1
port 2 Configuration information 2
port 3 Configuration information 3
In step S240, a mapping relationship sent by the management switch is received, where the mapping relationship is a mapping relationship between an interface of the management switch connecting the network element device and a management IP address of the network element device.
In this embodiment, if the management switch starts a DHCP Snooping function, the management switch may snoop the interactive message between the network element device and the DHCP server through the DHCP Snooping function, so as to obtain the mapping relationship. And as mentioned above, the network management software brings the management switch into management, so the management switch can send the obtained mapping relationship to the network management software, and correspondingly, the network management software can receive the mapping relationship sent by the management switch. Illustratively, the management switch and the network management software can communicate with each other through messages in a format such as a network configuration protocol.
In a possible implementation manner, the mapping relationship sent by the management switch may be received as follows:
step one, an instruction for starting a DHCP Snooping function of a management switch is sent to the management switch to start the DHCP Snooping function of the management switch;
step two, receiving the mapping relation sent by the management switch,
the management switch intercepts an application message and a response message interacted between the network element equipment and the DHCP server through a DHCP Snooping function to obtain the mapping relation, wherein the application message is a message which is sent by the network element equipment and is used for applying for a management IP address, and the response message is a message which is returned by the DHCP server aiming at the application message and carries the management IP address of the network element equipment.
In this embodiment, the network management software may start the DHCP Snooping function of the management switch by sending an instruction to the management switch. After the DHCP Snooping function is started, the management switch can intercept an application message sent by the network element device through the DHCP Snooping function to acquire an interface of the management switch for connecting the network element device. And the management switch can intercept the response message returned by the DHCP server through the DHCP Snooping function to acquire the management IP address of the network element equipment.
Since the management switch acquires the interface of the self-connected network element device and the management IP address of the network element device, the management switch can acquire the mapping relationship by corresponding the acquired interface of the self-connected network element device to the management IP address of the network element device one by one.
The VCF network shown in fig. 1 is taken as an example for illustration. Assuming that the management switch acquires that its interface port1 is connected to the management interface of the root node 1 and the management IP address of the root node 1 is 1.1.1.1, acquires that its interface port2 is connected to the management interface of the root node 2 and the management IP address of the root node 2 is 2.2.2.2.2, acquires that its interface port3 is connected to the management interface of the root node 3 and the management IP address of the root node 3 is 3.3.3.3 through the DHCP Snooping function, the management switch may acquire the mapping relationship shown in the following table 2.
Table 2 management mapping relationship between interfaces of the switch connecting the network element devices and management IP addresses of the network element devices
Interface for managing switch connecting network element equipment Management IP address of network element equipment
port1 1.1.1.1
port 2 2.2.2.2
port 3 3.3.3.3
In step S260, the management IP address of the network element device and the configuration information of the network element device are determined according to the mapping relationship and the corresponding relationship.
In this embodiment, the network management software may determine the same interface existing in the mapping relationship and the corresponding relationship, determine the management IP address corresponding to the same interface in the mapping relationship as the management IP address of the network element device connected to the interface, and determine the configuration information corresponding to the same interface in the corresponding relationship as the configuration information of the network element device connected to the interface.
For example, assuming that the network management software obtains the correspondence shown in table 1 and the mapping relation shown in table 2, the network management software may determine that the same interfaces existing in table 1 and table 2 are port1, port2, and port3, thereby determining that the management IP address of the root node 1 is 1.1.1.1 and the configuration information of the root node 1 is configuration information 1, the management IP address of the root node 2 is 2.2.2.2 and the configuration information of the root node 2 is configuration information 2, the management IP address of the root node 3 is 3.3.3.3 and the configuration information of the root node 3 is configuration information 3.
In step S280, the management IP address of the network element device and the configuration information of the network element device are sent to the controller in the VCF network.
Compared with the prior art in which an administrator manually configures the management IP address of the network element device and the configuration information of the network element device on the VCFC, in this embodiment, the network management software sends the management IP address of the network element device and the configuration information of the network element device to the VCFC, so that the VCFC can directly obtain the management IP address of the network element device and the configuration information of the network element device from the network management software without manually configuring the management IP address of the network element device and the configuration information of the network element device on the VCFC by the administrator, and the VCF network can be conveniently deployed.
And if a certain successfully on-line network element device fails and the management interface of the network element device is connected to the first interface of the management switch, the administrator does not need to reconfigure the other network element device, but only needs to replace the failed network element device with the other network element device, that is, the management interface of the other network element device is connected to the first interface of the management switch instead of the connection between the management interface of the failed network element device and the first interface of the management switch, because the configuration information corresponding to the first interface of the management switch recorded by the network management software is not changed, the configuration information of the other network element device can be the same as the configuration information of the failed network element device, so that the other network element device can be directly on-line without repeating the on-line process.
FIG. 3 is a flow chart illustrating a method of configuration according to an example embodiment. The configuration method can be applied to network element equipment in a VCF network. As shown in fig. 3, the configuration method may include the following steps.
In step S320, the network management software in the VCF network receives the configuration information of the network element device determined by the network management software according to the configuration issuing method.
The description of determining the configuration information of the network element device by the network management software may refer to the description of the configuration issuing method shown in fig. 2, and is not described herein again.
In step S340, a system name of the network element device is configured according to the network element name in the configuration information, so that the system name is the same as the network element name, where the network element name is a name used by the controller to manage the network element device, and the system name is a name of the network element device itself.
Compared with the prior art in which the network element device generates its own system name according to its own management IP address and its own role, in this embodiment, the network element device configures the system name of the network element device according to the network element name in the configuration information sent by the network management software, so that the name (i.e., the network element name) used by the VCFC management network element device is consistent with the name (i.e., the system name) of the network element device itself, thereby facilitating an administrator to use the VCFC, and improving the usability of the VCFC.
FIG. 4 is a flow chart illustrating a method of configuration according to an example embodiment. The configuration method can be applied to network element equipment in a VCF network. As shown in fig. 4, the configuration method may include the following steps.
In step S420, the network management software in the VCF network receives the configuration information of the network element device determined by the network management software according to the configuration issuing method.
The description of determining the configuration information of the network element device by the network management software may refer to the description of the configuration issuing method shown in fig. 2, and is not described herein again.
In step S440, the virtual extensible local area network tunnel endpoint VTEP IP address in the configuration information is configured as the VTEP IP address of the network element device.
Compared with the prior art in which the network element device generates its own VTEP IP address according to its own management IP address or its own MAC address, in this embodiment, the network element equipment configures the VTEP IP address of the network element equipment according to the VTEP IP address in the configuration information, therefore, if a network element device which is successfully on-line fails and the management interface of the network element device is connected to the first interface of the management switch, since the configuration information corresponding to the first interface of the management switch recorded by the network management software is not changed, by connecting the management interface of the further network element device to the first interface of the management switch, the configuration information of the further network element device can be made identical to the configuration information of the failed network element device, so that the VTEP IP address of the network element device to which the first interface of the management switch is connected does not change, therefore, the influence of replacing the network element equipment with the fault network element equipment for another network element equipment on the service can be reduced.
FIG. 5 is a flow chart illustrating one example of a configuration method in accordance with an example embodiment. As shown in fig. 5, the configuration method may include the following steps.
In step S1, the network management software brings the management switch in the VCF network into management, and records the correspondence between the interface of the management switch for connecting the network element device in the VCF network and the configuration information of the network element device. For a specific description, reference may be made to the description of step S220, which is not described herein again.
In step S2, the network management software starts the DHCP Snooping function of the management switch by sending an instruction for starting the DHCP Snooping function of the management switch to the management switch.
In step S3, the management switch starts a DHCP Snooping function, and listens to the application message and the response message interacted between the network element device and the DHCP server through the DHCP Snooping function, so as to obtain a mapping relationship between an interface of the management switch connecting the network element device and the management IP address of the network element device.
In step S4, the management switch transmits the acquired mapping relationship to the management server.
For the detailed description of steps S2 to S4, reference may be made to the description of step S240, and the description is not repeated here.
In step S5, the network management software receives the mapping relationship sent by the management switch, and determines the management IP address of the network element device and the configuration information of the network element device according to the mapping relationship and the corresponding relationship. For a specific description, reference may be made to the description of step S260, which is not described herein again.
In step S6, the network management software sends the management IP address of the network element device and the configuration information of the network element device to the VCFC, and sends the configuration information of the network element device to the network element device. For a specific description, reference may be made to the description of step S280, which is not described herein again.
In step S7, the network element device sends registration information to the VCFC according to the address of the VCFC in the configuration information, where the registration information carries the management IP address of the network element device and the configuration information received from the network management software.
In step S8, the VCFC receives registration information from the network element device and receives management IP address and configuration information from the network management software, and matches the management IP address and configuration information carried in the registration information with the management IP address and configuration information received from the network management software, respectively, and if the matching is successful, executes step S9.
In step S9, the VCFC allows the network element device to go online.
