System and method for dormant network hosting of manipulator in actual combat drill scene of network shooting range

Abstract

The invention discloses a dormant network hosting system and method for an operating machine in a network shooting range actual combat drill scene. When the operating machine is dormant, the invention saves the network configuration record of the dormant operating machine, generates and sends a virtual switch flow table, and transfers the target For the dormant state, the traffic of the operating machine is diverted to the network range control node; when the operating machine recovers from the dormant state, the saved network configuration records are cleaned up, and the flow table records corresponding to the virtual switch are deleted; The ARP protocol, RARP protocol, DHCP protocol, and ICMP protocol flow reply corresponding response messages, and periodically send the renewal message of the operating machine in the dormant state to the DHCP server to ensure that the IP address of the operating machine in the dormant state does not expire. The invention can improve the flexibility of operation and maintenance, support the DHCP server scheme of the dynamic distribution mode, improve the resource utilization rate, and increase the number of operating machines supported by the network shooting range.

Description

technical field [0001] The invention relates to a dormant network hosting system and method for a manipulator in an actual combat drill scene of a network shooting range, and belongs to the field of network technology. Background technique [0002] The network shooting range refers to a test platform that simulates the real cyberspace offensive and defensive combat environment through the combination of virtual environment and real equipment, and can support combat capability research and weapon equipment verification. With the continuous development of the information age, the network environment is becoming more and more severe, and the demand for building a large-scale network environment for actual combat exercises has been continuously raised. [0003] The deployment diagram of the network shooting range actual combat exercise scene is as follows figure 1 As shown, the network shooting range connects control nodes, computing nodes, and the Internet through multiple phy...

AI Technical Summary

Problems solved by technology

There are the following problems in the combat process of the actual combat drill scene in the existing network shooting range: 1. Waste of resources

The long-term task operator still occupies memory and CPU resources when the task is not completed and is idle, resulting in waste of resources, resulting in the inability to create a combat operator for new tasks

2. The administrator of the network shooting range needs to manually coordinate the operation of the machine

3. The operation and maintenance flexibility of the operating machine in the dormant state is poor

For the operating machine that is not needed temporarily, it can be hibernated. The network configuration of the dormant operating machine will be retained on the control node. When creating a new virtual machine, the reserved IP address will not be occupied. When it needs to be used, restore the operating machine. At the same time, it is guaranteed that the restored operation machine still adopts the original network configuration. It can only prevent the IP from being occupied by the virtual machine creation process. The secondary configuration of the virtual machine will still cause the IP to be occupied in the dormant state. The commonly used Ping command is used to judge the IP occupation. The method fails

4. Poor support for the dynamic allocation mode DHCP server solution

The DHCP server adopts the dynamic allocation method, the IP of the dormant virtual machine whose lease expires is released, and the released IP is easily occupied by other virtual machines
