Background Art

[0002] The development of modern cloud computing technology and big data environment has brought more challenges to the network structure of financial industry data centers. In order to adapt to more complex data environments, large-scale networks in modern data centers mostly adopt leaf-spine-border architecture, which consists of three main layers: Leaf layer, Spine layer and Border layer. The Leaf layer consists of multiple Leaf switches. The control of each layer of equipment is independent of each other, making it difficult to perform unified traffic scheduling and management, which brings great difficulties to network operation and maintenance. In order to solve this problem, SDN technology came into being and gradually developed into an indispensable part of network operation and maintenance.

[0003] As a new type of network technology, SDN technology brings many advantages to data centers by separating the network control plane and the data forwarding plane and managing the network in a unified manner through a centralized controller. SDN technology can be divided into software SDN and hardware SDN. Software SDN can avoid excessive reliance on hardware network devices and reduce the cost of networking. Therefore, it has been gradually piloted and applied on a large scale in the financial industry in recent years. However, due to its special architecture and implementation method, software SDN technology also brings many inconveniences to operation and maintenance work.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here.

[0024] As introduced in the background technology, the existing technology cannot quickly locate the virtual machine associated with the Leaf switch port. In order to solve the problem that the existing technology cannot quickly locate the virtual machine associated with the Leaf switch port, the embodiments of the present application provide a method, system, automation platform, computer-readable storage medium and electronic device for locating a virtual machine based on a software SDN architecture.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Figure 1 FIG. 1 is a flow chart of a method for locating a virtual machine based on a software SDN architecture according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0027] Step S201, using the LLDP protocol to obtain LLDP information of the Leaf switch, wherein the LLDP information includes name information of the Leaf switch port and the connected device;

[0028] Specifically, the Link Layer Discovery Protocol (LLDP) of the data link layer is needed to learn the name of the opposite device connected to a certain port. In the data link layer, the Link Layer Discovery Protocol is a Layer 2 protocol defined in IEEE 802.1ab, which enables network devices (such as switches) to transmit LLDP packets (Link Layer Discovery Protocol Data Unit) within a local area network to announce their own status details to other devices, including device identity, interface number, management IP and other information. This practice facilitates the discovery of the physical layout of network devices and the acquisition of their management configuration information.

[0029] Step S202, traversing the Leaf switch ports according to the LLDP information, obtaining the LLDP device name according to the Leaf switch port, and determining the device name information connected to the Leaf switch port according to the LLDP device name;

[0030] Specifically, the Leaf switch exchanges LLDP packets with the port device through the link layer discovery protocol, and learns the device name information connected to the port through the packet. The automation platform can first log in to the corresponding Leaf switch and view the LLDP device name learned by the Leaf switch port to obtain the device name information connected to all ports.

[0031] Step S203, calling the cloud platform interface to query server information according to the LLDP device name, wherein the server information includes virtual machine information;

[0032] Step S204: According to the server information and the device name information, the correspondence between the Leaf switch port and the virtual machine is obtained, and the virtual machine is located according to the correspondence.

[0033] Specifically, after querying the server information on the cloud platform according to the LLDP device name, the server name in the device can be successfully selected, but the virtual machine information is still unknown. In order to centrally manage computing resources, the cloud platform will also save the correspondence between the server and the virtual machine it carries when selecting the server to which the virtual machine is sent. Based on this, the automation platform can obtain the virtual machine information carried on the server stored by the cloud platform by further accessing the cloud platform, and combine the previously obtained connection relationship between the Leaf switch port and the server to finally establish a mapping relationship between the Leaf switch port and the virtual machine, thereby locating the virtual machine.

[0034] Through this embodiment, the LLDP protocol is used to obtain the LLDP information of the Leaf switch, wherein the LLDP information includes the name information of the Leaf switch port and the connected device; the Leaf switch port is traversed according to the LLDP information, the LLDP device name is obtained according to the Leaf switch port, and the device name information connected to the Leaf switch port is determined according to the LLDP device name; the cloud platform interface is called to query the server information according to the LLDP device name, wherein the server information includes the virtual machine information; according to the server information and the device name information, the correspondence between the Leaf switch port and the virtual machine is obtained, and the virtual machine is located according to the correspondence. This solution dynamically obtains the port information of the Leaf switch at any time, and combined with the access query to the cloud platform, the virtual machine connected to the port can be located in time. The whole process is efficient, timely, and can be realized automatically, without the need for manual regular maintenance. It can completely solve the problem of locating the virtual machine in scenarios such as Leaf switch failure or Leaf switch port failure, and effectively help risk control and troubleshooting.

[0035] During the specific implementation process, after obtaining the LLDP device name according to the Leaf switch port, the method also includes: obtaining a server list, wherein the server list includes multiple server names; determining whether the LLDP device name contains the server name in the server list; when it is determined that the LLDP device name contains the server name, determining the device name information connected to the Leaf switch port according to the server name in the LLDP device name.

[0036] In the actual network architecture, the Leaf switch is not only connected to the server. Due to the hierarchical architecture and redundancy of the network, the Leaf switch is also connected to the Spine switch and other Leaf switches. Therefore, the LLDP device name learned by the port of the Leaf switch may be the Spine switch name, other Leaf switch names, or server names. The first two do not deploy virtual machines. In order to locate the virtual machine, the server name needs to be selected from all the learned device names.

[0037] Specifically, before calling the cloud platform interface to query the server information according to the LLDP device name, the method also includes: determining whether the server information is queried according to the LLDP device name by calling the cloud platform interface; if it is determined that the server information is not queried, it indicates that the Leaf switch port is not connected to the server, and directly traverses the next Leaf switch port.

[0038] This method can query the LLDP device name learned by the switch on the cloud platform by calling the cloud platform interface. If the server information cannot be found, the Leaf switch port is not connected to a server device, and the next Leaf switch port is skipped. After an automatic traversal, the automation platform can echo the corresponding information between the port and all directly connected server devices.

[0039] More specifically, after directly traversing the next Leaf switch port, the method also includes: determining whether all the Leaf switch ports of the Leaf switch are traversed; when all the Leaf switch ports of the Leaf switch are traversed, generating a connection table of the Leaf switch ports of the Leaf switch, wherein the connection table is a connection relationship table of the Leaf switch ports of the Leaf switch.

[0040] If the method fails to find the server information, the Leaf switch port is not connected to a server device, and the next Leaf switch port is skipped. After an automatic traversal, the automation platform can echo the corresponding information of the port and all directly connected server devices.

[0041] Furthermore, after obtaining the correspondence between the Leaf switch port and the virtual machine according to the server information and the device name information, the method further includes: when receiving the fault alarm information of the virtual machine, locating the faulty virtual machine according to the correspondence.

[0042] This method automatically and timely obtains the information of the virtual machine connected to the Leaf switch port when an alarm or failure occurs, which completely solves the problem of quickly locating the virtual machine associated with the Leaf switch port under the software SDN architecture.

[0043] Furthermore, after locating the faulty virtual machine according to the corresponding relationship, the method further includes: generating prompt information, where the prompt information is used to prompt to perform inspection and maintenance processing on the faulty virtual machine.

[0044] This embodiment also provides a virtual machine positioning system based on software SDN architecture, such as Figure 2 As shown, including:

[0045] An automation platform, the automation platform is used to execute any method for locating a virtual machine based on a software SDN architecture;

[0046] Leaf switches: Leaf switches are connected to other Leaf switches on the server spine switch through Leaf switch ports. Leaf switches are used for data forwarding.

[0047] Cloud platform, which provides virtual machine creation, management, monitoring, backup, and recovery services;

[0048] Server, the virtual machine is deployed in the server, and the server carries the virtual machine information.

[0049] In the network architecture, the cloud platform provides a series of services such as virtual machine creation, management, monitoring, backup, and recovery. In the process of creating a virtual machine, the cloud platform will select the server to which the virtual machine is sent according to a specific policy, so it will record the name information of all servers where the virtual machine is deployed.

[0050] The numerous ports of the Leaf switch in this system can be connected to multiple servers, and corresponding virtual machines are deployed on the servers. In the actual network architecture, the Leaf switch can also be connected to the Spine switch and other Leaf switches. The automation platform can log in to the Leaf switch through the SNMP protocol to achieve remote control of the switch. The cloud platform achieves centralized, automated and intelligent management of computing resources by managing server resources. At the same time, the automation platform can access the cloud platform resources and query the relevant information of the server recorded in the cloud platform. At the same time, the automation platform also integrates the function of monitoring virtual machine failure alarms.

[0051] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the method for locating a virtual machine based on a software SDN architecture of the present application will be described in detail below in conjunction with specific embodiments.

[0052] Software SDN is also known as Host Overlay. The biggest difference between it and hardware SDN (i.e. Network Overlay) is the location of the virtual machine gateway. In the hardware SDN architecture, the virtual machine gateway is usually deployed on a dedicated network hardware device, which usually has high performance and stability. In the cloud network with a leaf-spine-border structure, the virtual machine gateway is deployed on the Leaf switch. In daily information communication, the ARP table of the Leaf switch itself stores the corresponding information between the port and the virtual machine, so when a fault occurs, the corresponding relationship between the Leaf switch port and the virtual machine can be intuitively located. In software SDN, the virtual machine gateway is usually deployed on a general-purpose server, using server resources (such as CPU, memory, and storage) to perform network functions and control. In the cloud network, the virtual machine gateway is deployed on the host's vSwitch. The Leaf switch only forwards information, does not perceive the control layer and virtual machine information, and does not support the mapping and positioning of virtual machines and hardware access ports. Therefore, it is impossible to quickly locate the Leaf switch port corresponding to the hardware access of the virtual machine through the Leaf switch like hardware SDN.

[0053] Leaf switches are key nodes that connect to servers and other devices. Problems such as heavy port traffic, port failures, and Leaf switch failures or upgrades may often occur in the network. It is necessary to locate the virtual machine connected to the port in a timely manner to help identify hidden dangers and troubleshoot. The existing technology generally records the corresponding mapping table between the virtual machine and the switch port at the beginning of virtual machine creation. When encountering problems such as failures, the mapping table is manually searched to traverse the mappings in the table one by one until the corresponding port mapping relationship is found, which can correspond to the virtual machine information connected to the port. This method requires manual operation, and it is difficult to locate and troubleshoot the virtual machine in a timely manner when a failure occurs. At the same time, when the virtual machine is migrated or the network topology undergoes other dynamic changes, the mapping table needs to be manually maintained in a timely manner, which cannot meet the needs of modern operation and maintenance.

[0054] This embodiment relates to a specific method for locating a virtual machine based on a software SDN architecture.

[0055] like Figure 2 As shown in the figure, the system of virtual machines based on software SDN architecture includes Leaf switches, servers, cloud platforms, and automation platforms. The many ports of Leaf switches can be connected to multiple servers, and corresponding virtual machines are deployed on the servers. In the actual network architecture, Leaf switches can also be connected to Spine switches and other Leaf switches. The automation platform can log in to the Leaf switch through the SNMP protocol to achieve remote control of the switch. The cloud platform achieves centralized, automated, and intelligent management of computing resources by managing server resources. At the same time, the automation platform can access the resources of the cloud platform and query the relevant information of the server recorded in the cloud platform.

[0056] In the software SDN architecture, Leaf switches only forward data and are not aware of the application layer and virtual machine information. However, by obtaining the server information connected to the switch port and then understanding the deployed virtual machine information through the server, the virtual machine directly connected to the Leaf switch port can be located. In this process, querying the related devices connected to the switch port is the first step. In order to achieve this function, it is necessary to use the Link Layer Discovery Protocol (LLDP) of the data link layer to learn the name of the opposite device connected to a port, such as Figure 3 The specific method for locating a virtual machine based on the software SDN architecture shown includes the following contents:

[0057] In the data link layer, the Link Layer Discovery Protocol is a Layer 2 protocol defined in IEEE 802.1ab, which enables network devices (such as switches) to transmit LLDP packets (Link Layer Discovery Protocol Data Unit) within the local area network to announce their own status details to other devices, including device identity, interface number, management IP and other information. This practice promotes the discovery of the physical layout of network devices and the acquisition of their management configuration information. Based on this, the Leaf switch exchanges LLDP packets with the port device through the Link Layer Discovery Protocol, and through the packets, the device name information connected to the port can be learned. The automation platform can first log in to the corresponding Leaf switch, view the LLDP device name learned by the Leaf switch port, and obtain the device name information connected to all ports.

[0058] In the actual network architecture, Leaf switches are not only connected to servers. Due to the hierarchical architecture and redundancy of the network, Leaf switches are also connected to Spine switches and other Leaf switches. Therefore, the LLDP device name learned by the port of the Leaf switch may be the Spine switch name, other Leaf switch names, or server names. The first two do not deploy virtual machines. In order to locate the virtual machine, you need to select the server name from all the learned device names.

[0059] In the network architecture, the cloud platform provides a series of services such as virtual machine creation, management, monitoring, backup, and recovery. In the process of creating a virtual machine, the cloud platform will select the server to which the virtual machine is sent according to a specific policy, so it will record the name information of all servers where the virtual machine is deployed. Based on this, the automation platform can query the LLDP device name learned by the switch on the cloud platform by calling the cloud platform interface. If the server information cannot be queried, the Leaf switch port is not connected to a server device, and the next Leaf switch port is skipped directly. After an automatic traversal, the automation platform can echo the corresponding information between the port and all directly connected server devices.

[0060] After the automation module platform queries the server information on the cloud platform according to the LLDP device name, it can successfully select the server name in the device, but the virtual machine information is still unknown. In order to centrally manage computing resources, the cloud platform will also save the correspondence between the server and the virtual machine it carries when selecting the server to which the virtual machine is sent. Based on this, the automation platform can further access the cloud platform to obtain the virtual machine information carried on the server stored by the cloud platform, and combine the previously obtained connection relationship between the Leaf switch port and the server to finally establish a mapping relationship between the Leaf switch port and the virtual machine, thereby locating the virtual machine.

[0061] This embodiment can be applied not only in the software SDN architecture, but also in the hardware SDN architecture. It is a solution that can cover switches from all manufacturers. In the event of an alarm or failure, it automatically and timely obtains the virtual machine information connected to the Leaf switch port, which completely solves the problem of quickly locating the virtual machine associated with the Leaf switch port under the software SDN architecture. Remote login based on the automation platform can dynamically obtain the port information of the Leaf switch at any time. Combined with the access query to the cloud platform, the virtual machine connected to the port can be located in time. The whole process is efficient, timely, and can be realized automatically. It does not require manual regular maintenance. It can completely solve the problem of locating virtual machines in scenarios such as Leaf switch failure or Leaf switch port failure, and effectively help risk control and troubleshooting.

[0062] The embodiment of the present application also provides an automation platform. It should be noted that the automation platform of the embodiment of the present application can be used to execute the positioning method for a virtual machine based on a software SDN architecture provided by the embodiment of the present application. The automation platform is used to implement the above-mentioned embodiments and preferred implementation modes, and those that have been described will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function.
