Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A fast, convenient and accurate network configuration technology needs to be found, so that a user can select different interface modes to perform network configuration allocation according to actual requirements, simulate a large-scale virtual network, realize various network behaviors required by the virtual network and communication behaviors among nodes, and further increase flexibility of network configuration allocation.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Because the real network structure is extremely complex, a single network address allocation mode cannot meet the requirements of some network structures. Therefore, the present invention aims to provide a method for configuring a destination network node, which can implement various network allocation modes. The technology mainly adopts different configurations for network topology to realize network configuration among various simulation network structure environment nodes.
The application discloses a network node configuration method, referring to fig. 1, the method includes:
step S101: acquiring the network topology of a target virtual network;
the method and the device can pre-construct the link information of the virtual network, and further construct a target virtual network needing network node configuration;
step S102: resolving the target virtual network based on the network topology;
after the network topology of the target virtual network is constructed, analyzing the target virtual network based on the network topology, and calculating the network topology of the target virtual network based on the basic rules of the network topology structure and the basic rules of the network connection to obtain the subnet network range, the subnet network segment, the subnet usable range or other data parameter information described by the network topology of the target virtual network;
step S103: acquiring a preset network configuration mode matched with a user input instruction;
in this embodiment, the user may set different network matching rules in each mode according to a plurality of preset different types of network configuration modes, for example, in this embodiment, these network configuration modes include but are not limited to: the system comprises a full-automatic distribution mode, a host self-defining mode, a host full-definition mode, a network self-defining mode and a range distribution mode.
In the full-automatic distribution mode, a user does not need to carry out any setting about network configuration, and the system automatically distributes network configuration information for nodes in the network topology and automatically calculates routing information.
In the host full definition mode, the system allows the network configuration of each host in the network to be fully defined, and a user can completely control the network configuration information of the nodes in the network, but all the network configuration information is input by the user, so that errors may occur in routing calculation, and the situation that IP addresses in subnets are not in the same network segment may occur, and meanwhile, the routing calculation is complicated.
The host self-defining mode is similar to the host full-defining mode, and the difference between the host self-defining mode and the host full-defining mode is that a user defines part of hosts in the network topology, the defined content is the same, other hosts in other network topologies carry out automatic completion configuration on the basis of the network topology defined by the user, and route information is calculated on the completed network topology.
In the network full definition mode, a user is allowed to fully define the configuration information in the network, and the system performs network construction work according to the network information configured by the user.
In the network self-defining mode, the user is allowed to partially define the configuration information in the network, and the system completes the rest completion according to the network information configured by the user and completes the construction work.
In the range allocation mode, a user is allowed to define a range for a certain area in the network topology and perform network configuration allocation, and the system performs information completion according to the network information configured by the user and completes the construction work.
Step S104: in the subnet network range, the subnet network segment and the subnet usable range, carrying out IP network allocation and routing calculation of a network topology structure on the nodes of the network topology based on the preset network configuration mode to obtain a network configuration file and a routing file which are matched with the network configuration mode;
in this step, after the subnet network range, the subnet network segment, and the subnet usable range of the target virtual network are determined, the network configuration mode used in the network layout is selected according to the selection of the user, in this scheme, the network configuration mode used this time may be selected from a plurality of preset network configuration modes by identifying a selection instruction issued by the user, or the network configuration mode used this time may be selected by judging the currently used network interface.
Step S105: constructing a virtual network based on the network configuration file and the routing file;
in this step, after the subnet network range, the subnet network segment, and the subnet usable range are calculated based on the preset network configuration mode, corresponding network configuration files and routing files are obtained, and then a virtual network is constructed based on the network configuration files and the routing files.
Therefore, the technical scheme disclosed by the embodiment of the application realizes selection of a proper network configuration mode based on different network configuration requirements, and provides an efficient network node distribution method.
