Network Data Resource Scheduling Strategy for Safety-Critical Testing Systems

For complex safety-critical systems such as spacecraft, a large amount of various types of data will be generated during the integrated testing process. In the case of limited network bandwidth and many users querying these test data at the same time, it will inevitably cause network communication delays and congestion. This will reduce the user experience and even cause delays in some important matters. In order to avoid the delay of important transactions and the phenomenon of network delay and congestion as much as possible, and to improve the user experience, this paper proposes a bandwidth allocation strategy based on the classification of access transaction importance, according to the characteristics of the complex safety-critical systems that emphasizes the importance of transactions. This method sets different levels for the importance of access transactions, and assigns different access authority priorities and network bandwidths according to these different levels. For access transactions with the same importance level, the first-come, first-served principle is adopted for resource allocation. Experimental results show that the network bandwidth allocation strategy proposed in this paper effectively avoids the delay of important transactions, reduces network congestion, and improves user satisfaction.
