Example Embodiment

[0065] Example 1

[0066] figure 1 Shows a flowchart of a method for distributing high-speed data provided by an embodiment of the present invention, such as figure 1 As shown, the method mainly includes:

[0067] Step S11: Sort the high-speed data in the order of generation.

[0068] When federation members send high-speed data, the simulation step size and this type of high-speed data are sorted in the order of generation.

[0069] Step S12: Pack and compress the sorted high-speed data according to types.

[0070] Step S13: Construct compressed interactive data.

[0071] Table 1 shows compressed interactive data constructed by an embodiment of the present invention.

[0090] Example 3

[0091] image 3 Shows a schematic diagram of data from the publisher to the subscriber, image 3 The publishing end is applicable to the method described in Embodiment 1, and the subscribing end is applicable to the method described in Embodiment 2. Such as image 3 As shown, the sender directly sends normal data to the HLA data distribution management service for release, performs high-speed data classification and compression for high-speed data, and then sends the compressed result to the data distribution service for release, which may correspond to step S11 described in Embodiment 1. -S14. The data distribution management sends the subscribed data to the receiver. After receiving the data, the receiver judges whether the data is high-speed data. If it is high-speed data, decompress and restore it, which can correspond to the steps S21-S22 described in Embodiment 2, and then process the restored data, otherwise directly process Normal data.

Abstract

The invention relates to a method and device for distributing high speed data. The method comprises the steps of sorting the high speed data according to a generation order, and then packing and compressing the sorted high speed data by type; and constructing compression type interaction class data, and calling a data distribution service to publish the compression type interaction class data. The method and the device for distributing the high speed data provided by the invention can reduce the amount of transmitted data and reduce the data packet transmission frequency.

Description

technical field [0001] The invention relates to the technical field of computer simulation, in particular to a high-speed data distribution method and device. Background technique [0002] At present, in the real-time simulation process based on HLA (Chinese: Advanced Architecture, English: High Level Architecture), RTI (Chinese: Runtime Underlying Structure, English: Run-Time Infrastructure) uses the original data transmission during data transmission, namely The data publisher sends the data to be sent to RTI according to the original data length without any processing, and RTI directly transmits the received data to the subscriber. [0003] When the existing RTI data distribution method transmits a large amount of or high-frequency data, due to the large amount of data, it is easy to cause RTI blockage. At the same time, when the data transmission frequency is too high and exceeds the minimum callback time allowed by the HLA support environment callback function, RTI wil...
