DETAILED DESCRIPTION OF THE INVENTION The following detailed description of the invention refers to the accompanying drawings that show, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It is to be understood that the various embodiments of the invention are different but need not be mutually exclusive. For example, certain shapes, structures, and characteristics described herein may be embodied in other embodiments without departing from the spirit and scope of the invention in connection with one embodiment. In addition, it is to be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled. Like reference numerals in the drawings refer to the same or similar functions throughout the several aspects.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the naval battle system, naval battle system design and operation method according to the present invention.

First, prior to describing the naval battle system and its operation method according to the present invention, a description will be given of the virtualization technology applied to the present invention.

Virtualization is a broad term for the abstraction of computer resources in a computer and refers to the technology of adding an abstraction layer between a computer hardware system and the applications running on it.

Hypervisor, the core technology of virtualization, is to run multiple operating systems on a single piece of hardware.

Type 1 (bare-metal or native) and type 2 (hosted) are classified according to the operating position of the hypervisor.

The trap battle system according to the present invention uses Type 1 in which the hypervisor controls the hardware instead of the host OS as shown in FIG.

Between type 2, which is run by the hypervisor between the host OS and the guest OS, type 1 controls the hardware directly without passing through the host OS, resulting in better performance.

Server virtualization allows you to run more than one operating system on a single computer at the same time, with most servers using only 10-15% of their capacity, which virtualizes more than 70% of their utilization rates. I can raise it.

High utility rates reduce the number of computers required for the same amount of work. In terms of cost, it also offers advantages in Total Cost of Ownership (TCO), such as lower hardware costs, lower management and operating costs, lower power and cooling costs, and lower floor space.

3 is a view schematically showing a naval battle system according to an embodiment of the present invention.

Naval vessel combat system 100 based on the virtualization technology according to the present invention is a Command Fire Command System (CFCS) (111), sensor equipment 120, armed equipment 130 and data link equipment (140) It can be made, including.

The CFCS 110 performs a series of information processing functions by integrating the target information obtained from the sensor equipment 120 to accurately inform the operator of the tactical situation and enable rapid engagement.

As described above, the CFCS 110 includes a multi-function console (MFC) 111, an integrated ICU 113, an integrated IPN 115, various displays (console) Monitors, operational monitors, video monitors, etc.) 117 or the like.

The MFC 111 receives the operator's command and displays the tactical situation.

The integrated ICU 113 may be achieved by integrating interworking modules of a plurality of interface control units (ICUs) in charge of interworking between the conventional sensor equipment 120, the armed equipment 130, and the data link equipment 140. have.

The integrated IPN 115 may be achieved by integrating information processing modules of a plurality of conventional ICUs.

Conventionally, a plurality of ICUs, interworking modules for converting messages from sensor equipment 120, armed equipment 130, and data link equipment 140 into combat system unified network messages and source target acquisition / processing, equipment control and status It consists of an information processing module in charge of information processing.

In the exemplary embodiment of the present invention, the integrated ICU 113 may be integrated into one integrated ICU 113, and the information processing module of the conventional ICU may be integrated into one integrated IPN 115.

Here, the plurality of interworking modules integrated with the integrated ICU 113 may be implemented as virtual machines (VMs), and the plurality of information processing modules integrated with the integrated IPNs 115 are also implemented as VMs. Can be.

The integrated ICU 113 and the integrated IPN 115 may be implemented as a high performance server, and a plurality of interworking modules and information processing modules implemented as VMs may be mounted in each server.

In addition, according to an embodiment of the present invention, an information processing device (IPN) having a single board computer (SBC) for processing data, an image distribution system for distributing and transmitting radar video and TV / IR video. At least one of a device (Radar Tv Video Distributor Unit: RTVDU) and a data link processor (DLP) for transmitting data between interworking systems may be implemented as a VM and integrated with the integrated IPN 115. .

On the other hand, the sensor equipment 120 may be composed of a search radar, tracking radar, sonar, etc., the armed equipment 130 may be composed of guns, guided missiles, missiles, torpedo tubes, etc., the data link equipment 140 is Tactical data communication equipment, transmission data links, and the like.

The trap battle system based on the virtualization technology according to the present invention uses a distributed data service (DDS), which is a communication middleware, for data transmission and reception between nodes. Therefore, it is possible to change only the execution node without modifying the software (SW), thereby allowing 100% reuse of the existing ship combat system SW.

On the other hand, in the embodiment of the present invention, it is desirable to implement the VM as an OS used in the existing configuration equipment so that the existing SW can be used as it is without SW porting.

In addition, it is desirable to configure a virtual network so that communication between CMS components can be performed through the same interface as the existing one.

In addition, by integrating modules whose utility rates fall below a preset value into a single VM, they can be designed by dramatically reducing the number of components compared to the conventional configuration while satisfying the availability requirements.

Here, the VM formed by integrating modules whose utility rate falls below a predetermined value may be mounted in the integrated IPN 115.

As described above, in the embodiment of the present invention, the virtualization-based naval combat system is composed of the integrated ICU 113 and the integrated IPN 115 (hereinafter, the integrated ICU and the integrated IPN collectively referred to as integrated equipment). The naval battle system maintains the overall operability of the naval battle system even if a number of components consisting of SBCs are installed in a plurality of compartments, and the operational capability of some components is lost due to the enemy attack.

However, since the integrated equipment of the virtualization-based naval battle system according to the present invention integrates several components into a single device, the operation of the naval battle system is greatly reduced when the corresponding equipment loses its operational capability.

Accordingly, in the embodiment of the present invention, it is assumed that X integrated equipment is configured to simulate the attack of the enemy ship to quantify the survival rate and compare with the existing naval battle system.

The survival calculation formula used for the simulation is as follows.

The total compartment is assumed to be 10 here.

The equipment of the conventional combat system is divided into five compartments (m + l) and consists of two ICU compartments, two redundant IPN compartments, and one DLP compartment. If the ICU becomes unavailable, the sensors or weapons of that ICU are not available, and if the DLP becomes unavailable, it is not possible to send and receive target and data information between friendly ships. If the IPN becomes unavailable, most of the ship's combat system is lost. Survival values for each compartment are defined as 50, 20, and 10 in order of IPN, ICU, and DLP, taking into account the importance of the equipment, and the sum is 20 + 20 + (50 + 50) / 2 + 10 = 100.

On the other hand, the integrated equipment of the virtualization-based naval battle system uses one compartment, and since there is one equipment, the survival rate is calculated as 100. It is assumed that the self-ship is hit by 50 (n) due to enemy ships, and each compartment calculates the survival rate of the compartment as 0 when 3 shots are taken. The chambers to be hit are simulated by generating random numbers through programming.

Table 1 shows the result (x) of changing the number of integrated equipment of virtualization-based ship combat system to 1-3.

The simulation results show that if there is only one integrated equipment of the virtualization-based naval battle system, the survival rate is similar to that of the conventional naval battle system. If there is only one integrated device, the result is similar to that of a conventional ship combat system. However, if the compartment equipped with the integrated device is hit and becomes unavailable, most of the function of the ship combat system is lost until recovery. Therefore, it is desirable to configure the system so as to secure higher survivability than a conventional ship combat system by applying a failover function through the duplication or multiplexing of integrated equipment.

For the redundancy of integrated equipment, the VM management device that manages the integrated equipment in the active-standby method is required for managing the VM status information and recovering in case of operation and error.

As shown in FIG. 4, the VM management apparatus 119 receives the state information of the redundant integrated ICU 113 and the integrated IPN 115 and the state information of the virtual machine (VM), and the redundant integrated ICU 113. The first booted server among the integrated IPNs 115 operates in an operating state, and the late booted server operates in a standby state.

In addition, the VM management unit 119 satisfies the trap battle system redundancy condition by switching the operating-standby state when an error occurs in the server (the integrated ICU 113, the integrated IPN 115) or the VM.

In addition, the VM manager 119 transfers the server integrated ICU 113, the integrated IPN 115, or the VM in which the error occurs to the standby state through a recovery step.

The SW implementing the VM management apparatus 119 may be implemented in a Windows-based C ++ language, and a class diagram is as shown in FIG. 5.

Specifically, the CMain class that has the main function, the CVMStatusMgr class that manages the status information of the server and VM, the CVMProcess class that handles the operation-standby operation of the server and VM, the CVMDisp class that displays the status information of the current server and VM, and It can be composed of CCommMgr and CUdpComm classes for communication with server and VM.

Class details are shown in Table 2.

6 is a process for explaining a design method of the naval battle system according to an embodiment of the present invention.

In the conventional naval battle system, the plurality of ICUs in charge of interworking between the sensor equipment 120, the armed equipment 130 and the data link equipment 140, the sensor equipment 120, armed equipment 130 and data link equipment ( It consists of an interworking module for converting the message of 140) into a battle system integrated network message, and an information processing module responsible for source target acquisition / processing, equipment control, and status information processing. A plurality of virtual machines (VMs) corresponding to the interworking modules of the server are generated (S10).

In operation S20, a plurality of VMs corresponding to the information processing modules of all the ICUs are generated.

Subsequently, a plurality of interworking modules implemented as a VM are integrated into one integrated ICU 113 through step S10 (S30).

The integrated ICU 113 in which a plurality of interworking modules implemented as a VM are integrated in step S30 may be implemented as a high performance server, and may be redundant or multiplexed.

In step S20, a plurality of information processing modules implemented as VMs are integrated into one integrated IPN 115 and configured (S40).

The integrated IPN 115 in which the plurality of information processing modules implemented as a VM are integrated in step S40 may be implemented as a high performance server, and may be redundant or multiplexed.

The redundant or multiplexed integrated ICU 113 and integrated IPN 115 may be managed by the VM management unit 119, and the VM management unit 119 may be configured to include the redundant integrated ICU 113 and the integrated IPN 115. The state information and the state information of the VM are received to manage the integrated ICU 113, the integrated IPN 115, and the VM.

In addition, in the embodiment of the present invention, an information processing apparatus (IPN) having a single substrate computer (SBC) for processing data, an image distribution apparatus (RTVDU) for distributing and transmitting radar video and TV / IR video, and interworking systems At least one of the data link processor (DLP) for transmitting data between the implementation may be implemented as a VM, and then integrated into the integrated IPN 115.

Then, after a module whose utility rate falls below a preset value is implemented as a VM, it may be configured by integrating it into the integrated IPN 115.

7 is a flowchart illustrating a method of operating a naval combat system according to an embodiment of the present invention.

First, in the naval battle system 100 in which the integrated ICU 113 and the integrated IPN 115 are duplicated, the status information of the integrated ICU 113 and the integrated IPN 115 that the VM manager 119 is duplicated and The integrated ICU 113 and the integrated IPN 115 to manage the VM by receiving the status information of the VM, the integrated ICU 113 is booted first for the redundant integrated ICU 113, the integrated IPN 115 and The integrated IPN 115 is operated in an operating state, and the integrated ICU 113 and the integrated IPN 115 which are late booted are operated in a standby state (S110).

Thereafter, when an error occurs in the integrated ICU 113, the integrated IPN 115, or the VM in an operational state, the failed integrated ICU 113, the integrated IPN 115, or the VM is switched to the standby state, and the standby state. The integrated ICU 113, the integrated IPN 115 or the VM is switched to an operational state so that an unavailable state does not occur (S120, S130).

When the integrated ICU 113, the integrated IPN 115, or the VM that has failed in the above-described step S130 is put into the standby state, after recovering the integrated ICU 113, the integrated IPN 115, or the VM that has failed, It is desirable to switch to the standby state.

In order to test the virtualization-based naval combat system according to the present invention, two test sets are constructed as shown in FIG.

The former uses the SBC to implement the trap battle system SW of ICU, IPN and RTVDU. The latter uses a high-performance server to run the trap battle system SW of the integrated equipment and the VM management SW using the desktop.

Like both test sets, the sensor, armed and datalink simulators utilize the simulators used in the Landing Based Test System (LBTS) and use the desktop to run the MFC's naval battle system SW. The specifications of the SBC and high performance server used in the test environment and the test environment details may be as shown in Table 3. The VM configuration of the virtualization-applied high performance server can be configured as shown in FIG. Conventional ship combat system SW Reuse creates the same number of VMs as conventional ship combat systems, and pairs two servers to form the same VM for redundancy. Internally, the network, video network, and combat system data network for VM control are divided and configured through virtual switches.

In the test environment as described above, the test simulates simultaneous combat against multiple targets that are heavily loaded in the naval battle system, 1000 target processing, and simultaneous operation of tactical / training modes, allowing the CPU and memory of each SBC and integrated equipment to be simulated. You can proceed by recording the utilization of 1 hour. Details of each test case may be as shown in Table 4.

As shown in FIG. 10, the CPU and memory of the ICU are measured to be higher than the standby state after the first boot, and the CPU usage of the IPN is in the tactical / training mode concurrent operation situation. In each case, the memory usage of the IPN is measured high. The CPU usage of the integrated ICU is estimated to be 120 ~ 133% higher than before, but considering the redundancy, the use of 33-40% will decrease. The CPU usage of the integrated IPN is 45% lower than before. Memory usage has been reduced by 20 ~ 34% compared to both the integrated ICU and integrated IPN. The CPU benchmarks for the virtualization-based ship combat system test set are 45% higher than the existing ship combat system test set, and the memory size is increased by 60%, resulting in a reduction in CPU usage similar to benchmarks. It's a bit higher than expected, but it's also decreasing.

The reason for the small decrease in memory usage is the overhead caused by the increased memory used by the OS of the VM allocated to the virtualization server for system management. The overhead incurred by the CPU is not larger than the memory due to the characteristics of Type 1 virtualization, which does not significantly affect the test results.However, in the integrated ICU with a large number of VMs, the CPU usage decreases 5 to 12% less than the integrated IPN. Since the network data used by the ship's battle system SW is about 10Mbps, which is 1% of 1Gbps bandwidth, it is not affected by the loss caused by the overhead of using virtualization tools. desirable.

The total number of VMs used in the virtualization-based ship combat system test set is 46, which gives about 200% margin of availability requirements, given that the maximum CPU usage is less than 20%. This means that you can utilize the processing power of more than 90 SBCs by adding VMs without physical changes, which is a great advantage compared to the existing ship combat system in terms of scalability.
