Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the method for modifying a network configuration of a 5G communication virtual network element according to the preferred embodiment of the present invention includes the following steps:
s10, the management terminal is remotely connected to a network interface of the virtual network element through the Ethernet and modifies the configuration related to the network function of the virtual network element;
step 20, after the operation of modifying the configuration related to the network function of each virtual network element is completed, judging whether the virtual network element receives a data packet of a communication test sent by the management terminal through the Ethernet within a preset time;
step S30, when the virtual network element does not receive the data packet of the communication test within the preset time, returning to the state before the configuration related to the network function of the virtual network element is modified, and recovering the communication between the management terminal and the virtual network element.
Specifically, the management terminal mainly refers to a network administrator who modifies the configuration related to the network function of the virtual network element through an intelligent device, the management terminal establishes a remote connection with a network interface of the virtual network element through an ethernet, and after the remote connection is successfully established, the network administrator can modify the configuration related to the network function of the virtual network element.
Wherein the operation of modifying the network function related configuration of the virtual network element comprises: modifying network interface IP addresses, adding routes, and deleting routes.
When the network administrator is remotely connected to the network interface of the virtual network element through the ethernet and modifies the configuration related to the network function of the virtual network element, after each operation (e.g., modifying the IP address of the network interface, adding a route, deleting a route) for modifying the configuration related to the network function of the virtual network element is completed, the virtual network element needs to receive a data packet of a communication test sent by the network administrator through the ethernet within a preset time (e.g., 30 seconds) to test whether the modified network configuration is correct, if the virtual network element receives the data packet of the communication test within the preset time, the modified network configuration is correct without performing other operations, if the virtual network element does not receive the data packet of the communication test within the preset time, the virtual network element considers that the network administrator (i.e., a management terminal) cannot be connected to the network interface of the virtual network element after the configuration related to the network function of the virtual network element is modified, and then the state of the network administrator before the configuration related to the network function of the virtual network element is modified is recovered (i.e., the principle that the communication function of the virtual network element is recovered).
The data packet of the communication test is a UDP (User Datagram Protocol, UDP provides a method for sending an encapsulated IP data packet without establishing a connection for an application), the UDP data packet does not have specific content data, and the virtual network element considers that the network communication is normal (a network administrator does not need to know whether the virtual network element receives the UDP data packet) as long as the virtual network element receives the UDP data packet; otherwise, the virtual network element considers that the network communication is abnormal, and the virtual network element returns to the state before modification.
Further, as shown in fig. 2, when the network administrator modifies the IP address of the network interface of the virtual network element, the following steps are performed:
s111, the management terminal sends an operation of modifying the IP address of the network interface into IP2 to the virtual network element;
s112, the virtual network element executes the operation of modifying the IP address of the network interface into IP2, and simultaneously records the IP address before modification as IP1;
s113, the virtual network element waits for the management terminal to send a data packet of the communication test, and if the data packet of the communication test is received within the preset time, the modification is successful;
and S114, if the data packet of the communication test is not received within the preset time, the virtual network element sets the IP address of the network interface to be IP1, and restores the original configuration.
There may be a plurality of network interfaces of the virtual network element.
For example, the network administrator sends an operation of modifying the IP address of network interface a (any one of multiple network interfaces) to IP2 to the virtual network element, the virtual network element executes the operation of modifying the IP address of network interface a to IP2, and records that the IP address before modification is IP1, the virtual network element waits for the network administrator to send a data packet of a network communication test, if the virtual network element receives the data packet of the communication test within 30 seconds, the modification is successful, and if the virtual network element does not receive the data packet of the communication test within 30 seconds, the virtual network element sets the IP address of network interface a to IP1, and restores the original configuration.
Further, as shown in fig. 3, when the network administrator modifies the add route in the virtual network element configuration, the steps are as follows:
s211, the management terminal sends an operation of adding a route to the virtual network element;
s212, the virtual network element executes the operation of adding a route;
s213, the virtual network element waits for the management terminal to send a data packet of the communication test, and if the data packet of the communication test is received within the preset time, the data packet is added successfully;
s214, if the data packet of the communication test is not received within the preset time, deleting the currently added route and recovering the original configuration.
For example, the network administrator sends an operation of adding a route R to the virtual network element, the virtual network element performs the operation of adding a route R, the virtual network element waits for the network administrator to send a data packet of a network communication test, and if the virtual network element receives the data packet of the communication test within 30 seconds, the addition is successful. And if the virtual network element does not receive the data packet of the communication test within 30 seconds, deleting the route R and recovering the original configuration.
Further, as shown in fig. 4, when the network administrator modifies the delete route in the virtual network element configuration, the steps are as follows:
s311, the management terminal sends an operation of deleting a route to the virtual network element;
s312, the virtual network element executes the operation of deleting one route;
s313, the virtual network element waits for the management terminal to send a data packet of the communication test, and if the data packet of the communication test is received within the preset time, the data packet of the communication test is deleted successfully;
and S314, if the data packet of the communication test is not received within the preset time, adding the currently deleted route and recovering the original configuration.
For example, the network administrator sends an operation of deleting a route R to a virtual network element, the virtual network element executes an operation of deleting a route R, the virtual network element waits for the network administrator to send a data packet of a network communication test, if the virtual network element receives the data packet of the communication test within 30 seconds, the deletion is successful, and if the virtual network element does not receive the data packet of the communication test within 30 seconds, the route R is added, and the original configuration is recovered.

Wherein the operation of modifying the network function related configuration of the virtual network element comprises: modifying network interface IP addresses, adding routes, and deleting routes.
For example, the management terminal sends an operation of modifying the IP address of the network interface to IP2 to the virtual network element; the virtual network element executes the operation of modifying the IP address of the network interface into IP2 and simultaneously records the IP address before modification as IP1; the virtual network element waits for the management terminal to send a data packet of the communication test, and if the data packet of the communication test is received within the preset time, the modification is successful; and if the data packet of the communication test is not received within the preset time, the virtual network element sets the IP address of the network interface to be IP1 and restores the original configuration.
For example, the management terminal sends an operation of adding a route to the virtual network element; the virtual network element executes the operation of adding a route; the virtual network element waits for the management terminal to send a data packet of the communication test, and if the data packet of the communication test is received within the preset time, the data packet is added successfully; and if the data packet of the communication test is not received within the preset time, deleting the currently added route and recovering the original configuration.
