Embodiment 1

[0052] Please refer to the attached figure 1 , is a schematic flow diagram of a data packet processing method disclosed in an embodiment of the present invention, the method is realized based on the OMNeT++ network simulation system, and includes the following steps:

[0053] S101: Obtain data packets to be processed.

[0054] It should be noted that the data packet to be processed is a simulation data packet to be sent or a physical data packet to be received. The simulation data packet comes from a mapping node, and the entity data packet comes from a physical terminal device. The mapping node is a virtual node in the simulation network, and is connected to the physical terminal equipment through a half-physical simulation interface.

Abstract

The invention discloses a data packet processing method and a data packet processing device, for acquiring a data packet to be processed. The method comprises the steps of performing address analysis on the data packet to be processed, thus obtaining the source address and target address of the data packet to be processed; when the source address and target address of the data packet to be processed meet a preset address matching rule, performing protocol conversion processing on the data packet to be processed to generate a converted data packet, and sending the converted data packet to a data packet processing queue for caching; performing synchronization signal analysis on the converted data packet, thus obtaining the processing time of the converted data packet, and generating a synchronization control signal when reaching the processing time; and based on the synchronization control signal, controlling the processing of the converted data packet in the data packet processing queue. According to the method and device, the half-practicality network real-time simulation based on the OMNeT++ network simulation system can be achieved.

Description

technical field [0001] The present invention relates to the technical field of hardware-in-the-loop simulation, and more specifically, relates to a data packet processing method and device. Background technique [0002] Semi-physical simulation is to add physical objects to the software simulation environment, use virtualization technology to realize some modules in the simulation test with software, and realize the important modules with hardware technology. Through semi-physical simulation, it can reduce the investment as much as possible while reducing the investment. close to the real result. The hardware-in-the-loop network simulation is the realization of the hardware-in-the-loop simulation on the network simulation software, that is, the external network devices are mapped to special nodes or devices in the network simulation software, and network simulation experiments are performed using real data. [0003] When simulating the hardware-in-the-loop network system, i...
