Embodiment Construction

[0043] Below in conjunction with accompanying drawing and example the present invention will be further described:

[0044] see figure 1 , figure 1 Shown is the hierarchical schematic diagram of the clock propulsion system of the present invention, by figure 1 It can be seen that a clock propulsion system consists of two parts: a clock propulsion server and a clock propulsion agent, which are respectively deployed on the server-side simulation node and the client-side simulation node. The clock advancing server is responsible for receiving the clock advancing request, selecting the clock advancing calculation service, calculating the maximum clock advancing step of the emulation node that initiated the request, and returning it to the client agent. The clock boosting agent provides three types of interfaces for simulation applications: clock initialization interface, clock registration interface and clock boosting request interface. For a clock advancing server, it can prov...

Abstract

The invention discloses a marching method for a service-oriented simulation clock. The method relates to a clock marching agent and a clock marching server arranged on each simulation node. The clock marching agents are used for providing simulation clock marching interfaces for users, automatically generating simulation clock marching information for the users, receiving clock marching computation results and feeding back the results to the users. The clock marching servers are used for receiving clock marching requests sent by the clock marching agents, loading clock marching service instances, computing clock marching step length and sending the clock marching results back to the clock marching agents. According to the marching method for the service-oriented simulation clock, in the step of computing the maximum safe time, influences of network delay on clock marching are considered, so each simulation node can receive complete clock marching information as much as possible in the clock marching process, and the phenomenon that operating states of the whole simulation system are affected due to clock event and information delay brought by poor network performance is avoided.

Description

technical field [0001] The invention relates to a computer simulation application technical field, in particular to a service-oriented simulation clock advancing method. Background technique [0002] With the wide application of computer simulation technology, especially the promotion of modern military requirements, distributed simulation technology is constantly developing towards high distribution, good interoperability and scalability. On the one hand, large-scale, fine-grained, and long-term distributed simulations have higher and higher requirements for system computing power, reliability, and fault tolerance; on the other hand, in response to flexible and changeable simulation task requirements, the construction method of simulation systems has changed As "model-centric", more emphasis is placed on the sharing, reuse and integration of simulation models distributed on the network. However, the existing HLA-based simulation systems have problems such as low resource u...
