Problems solved by technology

Since this method only considers congestion control by adjusting the data sending rate, but does not consider how to reduce the amount of invalid data sent, so when a large amount of invalid data is generated and transmitted in distributed simulation, this method will not increase Discriminately transmit various types of data, including data that is useless to the simulation program, so congestion control cannot be effectively performed

Embodiment Construction

[0048] Such as figure 1 As shown, the distributed simulation system data transmission congestion control method of the present invention comprises steps:

[0049] 10) Divide data transmission levels;

[0050] 20) determine whether congestion occurs;

[0051] 30) If congestion occurs, the publisher adjusts its sending rate according to the data transmission level at which it sends data, and the subscriber adjusts its receiving rate according to the data transmission level at which it receives data.

[0052] According to the importance of the transmitted data to the distributed simulation system, the data transmission level is divided, and the data with different importance levels are in different data transmission levels. When congestion occurs, the publisher adjusts its sending rate according to the data transmission level at which it sends data, and the subscriber adjusts its receiving rate according to the data transmission level at which it receives data, that is, the ord...

Abstract

The present invention discloses one data transmission congestion controlling method for distributive simulation system. The method includes the steps of: dividing data transmission layers; judging whether to have congestion; and if yes, regulating the transmitting rate in the data transmission layer by the issuer and regulating the receiving rate in the data transmission layer by the subscriber. The data transmission congestion controlling method for distributive simulation system processes various data in different importance separately to ensure the effective data transmission in congestion, and can fast lower the network burden to control congestion effectively.

Description

technical field [0001] The invention relates to the field of computer distributed simulation, in particular to a method for controlling data transmission congestion in a distributed simulation system. Background technique [0002] With the explosive growth of data transmitted in large-scale distributed simulation systems, congestion control in the process of transmitting these data has become one of the focal points affecting the scale of distributed simulation systems. Almost none of the existing distributed simulation systems can effectively implement congestion control during data transmission. [0003] In the distributed simulation system data transmission congestion control method proposed by Litton-TASC (www.tasc.com), active networks are applied to try to enhance network transmission and perform priority-based congestion control, and limit simulation applications and requirements to use new networking capabilities to enhance the filtering efficiency of data distribut...
