Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a network management method, device, medium and computer program product. Background Art

[0002] An IP (Internet Protocol Address) address conflict refers to a network connection conflict caused when two or more network devices are assigned the same IP address on the same network. Each network device must have a unique IP address in the network to communicate normally. When an IP address conflict occurs, the network device may not be able to connect to the network, resulting in an unstable network connection state. The current network management solution is a passive response to the detection and resolution of IP address conflicts, that is, after an IP address conflict occurs, the IP address conflict is resolved. Although resolving the IP address conflict after the IP address conflict occurs can restore the network connection of the network device with the IP address conflict, it will undoubtedly have a greater impact on the network device with the IP address conflict during the IP address conflict. Therefore, how to solve the above technical defects has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0047] The core of the present invention is to provide a network management method, device, medium and computer program product to predict whether an IP address conflict will occur, take optimization measures before the IP address conflict occurs, achieve effective defense against IP address conflicts, and improve the stability and reliability of the network.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Please refer to Figure 1 , Figure 1 A schematic diagram of a network management method provided by an embodiment of the present invention, referring to Figure 1 As shown, the method includes:

[0050] S101: Obtain historical IP address allocation data and current network status of all network devices under each virtual local area network.

[0051] The database stores the historical IP address allocation data and current network status of all network devices under each virtual local area network. The historical IP address allocation data may include the ports on the switch, the virtual local area network to which the ports on the switch belong, and the correspondence table between the repeatedly allocated IP addresses and MAC (Media Access Control Address).

[0052] In some embodiments, each of the virtual local area networks is configured with a corresponding subnet mask and a default gateway, and each of the virtual local area networks is configured with a corresponding virtual routing forwarding instance, the virtual routing forwarding instance is allocated with corresponding routing entries and ports, and each of the virtual local area networks is configured with a corresponding IP address pool.

[0053] VLAN (Virtual Local Area Network) technology is a technology that divides a local area network into multiple subnets in a logical way. VLAN technology allows a physical local area network to be divided into multiple logical local area networks. Network devices between different VLANs cannot communicate directly, which can improve network security and management efficiency. Each VLAN is an independent broadcast domain, which can reduce the impact of broadcast storms and improve network performance. VLAN can be used to divide the network according to department, application or geographical location, making network management more flexible and convenient. Users or devices can change the logical network they belong to through VLAN configuration without changing the physical connection, which can improve the mobility and scalability of the network.

[0054] VRF (Virtual Routing and Forwarding) is a technology that allows multiple instances of routing tables to coexist in the same router at the same time. One or more logical or physical ports may have a VRF, and these VRFs do not share routes, so packets are only forwarded between ports on the same VRF. Because virtual routing forwarding instances are independent, they can use the same or overlapping IP addresses without conflicting with each other, which can improve network functionality.

[0055] This embodiment uses VLAN technology and VRF technology to divide the network into several virtual local area networks, each of which is configured with a corresponding subnet mask and default gateway, and each of which is configured with a corresponding virtual routing forwarding instance, and the virtual routing forwarding instance is assigned with corresponding routing entries and ports, and each of which is configured with a corresponding IP address pool. This ensures that IP addresses between different VLANs are independently allocated. At the same time, VRF is used to manage different routing tables, which realizes the logical isolation of the network, prevents illegal access between different network areas, and enhances the security of the network.

[0056] S102: Predict whether there are IP addresses that will be repeatedly allocated based on the historical IP address allocation data and the current network status.

[0057] Based on the acquisition of historical IP address allocation data and the current network status, the historical IP address allocation data and the current network status are analyzed and processed to predict whether there are IP addresses that will be allocated repeatedly, that is, whether IP address conflicts may occur.

[0058] In some embodiments, predicting whether there are IP addresses to be repeatedly allocated based on the historical IP address allocation data and the current network status includes:

[0059] According to the historical IP address allocation data and the current network status, a decision tree algorithm or a random forest algorithm is used to predict whether there are IP addresses that will be repeatedly allocated.

[0060] This embodiment predicts whether there are IP addresses that will be repeatedly assigned based on a decision tree algorithm or a random forest algorithm. A prediction model can be constructed based on a decision tree algorithm. The prediction model constructed based on the decision tree algorithm analyzes features that are more likely to lead to repeated assignment of IP addresses (for example, the number of IP address assignments, MAC changes, VLAN numbers, etc.), and predicts whether a certain IP address will be assigned to a different network device again. By constructing a decision tree, network configurations that are prone to IP address conflicts can be identified. The random forest algorithm integrates multiple decision trees. A prediction model can be constructed based on a random forest algorithm. The prediction model constructed based on the random forest algorithm analyzes the frequency of IP address usage, historical IP address conflicts, VLAN configurations, VRF configurations, etc. to predict possible future IP address conflicts.

[0061] S103: If it is predicted that there is an IP address that will be repeatedly allocated, the IP address is reallocated to the target network device and the network configuration is adjusted; the target network device is a network device to which the IP address that is predicted to be repeatedly allocated has been allocated.

[0062] If it is predicted that there is an IP address that will be repeatedly allocated, then other unused IP addresses are allocated to the network device that has been allocated the IP address, and the network configuration is adjusted, including the configuration of the virtual local area network, the configuration of the virtual routing forwarding instance, etc., to avoid IP address conflicts. Among them, adjusting the configuration of the virtual local area network may be adjusting the IP address pool corresponding to the virtual local area network. Adjusting the configuration of the virtual routing forwarding instance may be adjusting the port corresponding to the virtual routing forwarding instance. If it is predicted that no IP address conflict will occur, no operation can be performed to maintain the current IP address allocation and network configuration.

[0063] In some embodiments, it also includes:

[0064] Detect whether there is an IP address conflict in the network;

[0065] If there is an IP address conflict in the network, an IP address is reassigned to the network device with the IP address conflict according to the IP address pool corresponding to the virtual local area network to which the network device with the IP address conflict belongs.

[0066] You can use ARP (Address Resolution Protocol) and network scanning tools (such as nmap, arp-scan) to regularly scan IP addresses in the network to identify duplicate IP addresses. When an IP address conflict is detected in the network, re-allocate IP addresses to the network devices with IP address conflicts based on the IP address pool corresponding to the virtual local area network to which the network devices with IP address conflicts belong, so that there is no IP address conflict.

[0067] Use ARP and network scanning tools to detect IP address conflicts in the network and automatically reallocate IP addresses to resolve IP address conflicts, ensuring that network devices obtain unique IP addresses, and avoiding manual intervention and reducing human errors.

[0068] Obtaining the historical IP address allocation data and the current network status of all network devices under each virtual local area network, and predicting whether there are IP addresses that will be repeatedly allocated based on this, can be performed periodically, or obtaining the historical IP address allocation data and the current network status of all network devices under each virtual local area network under the triggering of a certain event, and predicting whether there are IP addresses that will be repeatedly allocated based on this.

[0069] In some embodiments, when an IP address conflict is detected in the network, an IP address is reassigned to the network device with the IP address conflict, and the historical IP address allocation data and the current network status of all network devices under each virtual local area network are obtained, and based on the historical IP address allocation data and the current network status, it is predicted whether there are IP addresses that will be allocated repeatedly.

[0070] In this embodiment, when an IP address conflict is detected in the network, not only will the IP address be reassigned to the network device with the IP address conflict, but also the historical IP address allocation data of all network devices under each virtual local area network and the current network status will be used to predict whether an IP address conflict will occur in the future. Then, when it is predicted that an IP address conflict will occur in the future, optimization and adjustment will be automatically performed. This can effectively improve the automation and intelligence of network management and ensure the reliability and security of the network.

[0071] In some embodiments, it also includes:

[0072] Dividing the network into a plurality of said virtual local area networks;

[0073] A corresponding subnet mask and a default gateway are configured for each of the virtual local area networks.

[0074] This embodiment is intended to perform virtual local area network division and configuration. The VLAN function of the switch can be used to divide the network into multiple virtual local area networks according to different departments, uses, security requirements, etc. For example, according to the department, the network is divided into three virtual local area networks, the virtual local area network allocated to the sales department is VLAN10, the virtual local area network allocated to the R&D department is VLAN20, and the virtual local area network allocated to the finance department is VLAN30. Configure the corresponding subnet mask and default gateway for each virtual local area network. For example, VLAN10 uses subnet 192.168.10.0 / 24, and the default gateway is 192.168.10.1. VLAN20 uses subnet 192.168.20.0 / 24, and the default gateway is 192.168.20.1.

[0075] In some embodiments, it also includes:

[0076] Configuring a corresponding virtual routing forwarding instance for each virtual local area network;

[0077] Corresponding routing entries and ports are allocated to the virtual routing forwarding instance.

[0078] Use VRF instances, i.e. virtual routing and forwarding instances, to configure independent routing tables for each virtual local area network to achieve network isolation. For example, configure VRF instance VRF10 for VLAN10 and VRF instance VRF20 for VLAN20. Configure different VRF instances on the router and assign corresponding routing entries and ports to each VRF instance. For example, assign port GigabitEthernet0 / 1 to VRF10 and port GigabitEthernet0 / 2 to VRF20.

[0079] In some embodiments, it also includes:

[0080] A corresponding IP address pool is set for each virtual local area network; different virtual local area networks have different IP address pools.

[0081] This embodiment is intended to configure a DHCP (Dynamic Host Configuration Protocol) server. The DHCP server is configured to set a separate IP address pool for each virtual local area network. For example, the IP address pool set for VLAN10 is 192.168.10.2-192.168.10.254, and the IP address pool set for VLAN20 is 192.168.20.

[0082] In some embodiments, it also includes:

[0083] If an IP address conflict is detected in the network, information about the detected duplicated IP addresses and information about the IP addresses re-allocated to the network devices with the IP address conflict are recorded.

[0084] The log system records the information of the detected duplicated IP addresses, which may include the IP address itself, the virtual local area network corresponding to the IP address pool to which the IP address belongs, etc. In addition, the log system records the information of the IP address re-assigned to the network device with the IP address conflict, which may include the IP address itself, the virtual local area network corresponding to the IP address pool to which the IP address belongs, etc.

[0085] In some embodiments, it also includes:

[0086] Generate an alarm report; the alarm report includes information about duplicated IP addresses, information about reassigned IP addresses for network devices with IP address conflicts, network adjustment suggestions, and implemented network adjustment strategies.

[0087] The information of the IP address that is repeatedly allocated may include the IP address itself, the virtual local area network corresponding to the IP address pool to which the IP address belongs, etc. The information of the IP address that is re-allocated to the network device with the IP address conflict may include the IP address itself, the virtual local area network corresponding to the IP address pool to which the IP address belongs, etc. The network adjustment suggestion includes the predicted IP address that may be repeatedly allocated. The network adjustment strategy includes reallocating IP addresses and adjusting the configuration of virtual local area networks and virtual routing forwarding instances.

[0088] In some embodiments, it also includes:

[0089] The alarm report is sent to a network management personnel.

[0090] After the alarm report is generated, it is sent to the network administrator so that the network administrator can understand the network status in time and take further measures.

[0091] In some embodiments, sending the alarm report to a network administrator includes:

[0092] The alarm report is sent to the network administrator via email and / or text message.

[0093] After the alarm report is generated, it is sent to the network administrator via email and / or text message, so that the network administrator can understand the network situation in time and take further measures. For example, the SMTP (Simple Mail Transfer Protocol) protocol is used to send emails to send the alarm report to the network administrator. The SMS (Short Messaging Service) gateway is used to send text messages to send the alarm report to the network administrator.

[0094] In some embodiments, it also includes:

[0095] Count the probability of IP address conflicts under different network configurations;

[0096] The network configuration with the lowest probability of IP address conflict is selected as the optimal network configuration, so that when an IP address conflict is detected or predicted to occur, the network configuration is adjusted to the optimal network configuration.

[0097] A virtual local area network configuration, a virtual routing forwarding instance configuration, and a DHCP server configuration constitute a set of network configurations. The probability of IP address conflicts under different network configurations is counted, and the network configuration with the lowest probability of IP address conflicts is selected as the optimal network configuration. When an IP address conflict is detected or predicted to occur, the IP address is reassigned and the network configuration is adjusted to the optimal network configuration to reduce the probability of IP address conflicts and improve the reliability and security of the network.

[0098] In summary, the network management method provided by the present invention predicts whether there are IP addresses that will be repeatedly allocated, that is, predicts whether an IP address conflict will occur, based on the historical IP address allocation data of the network device and the current network status. When it is predicted that an IP address conflict will occur, the IP address is reallocated to the target network device, and the network configuration is adjusted; wherein the target network device is a network device that has been allocated an IP address that is predicted to be repeatedly allocated. In this way, optimization measures are taken before an IP address conflict occurs, and effective defense against IP address conflicts is achieved, which can improve the stability and reliability of the network.
