“…Because different communication tasks have different requirements for bandwidth and delay, a reasonable multitask scheduling mechanism needs to be designed to meet the transmission requirements of each task. Li [22] and He [19] used a static scheduling scheme with fixed time slots reserved for DT scheduling. Theoretically, static scheduling can calculate the best scheduling scheme for DTs; however, when the number and length of DTs change, the transmission of DTs may conflict when using a static scheduling scheme.…”

Given the increasing need of avionics communications and ship electromechanical communications for reliability and real-time transmission, current scheduling schemes waste bandwidth resources. They increase delay because of the low concurrency and the inefficiency of data transmissions in FC-AE-1553 multi-level switching networks. In this study, we first analyze the characteristics of different tasks in the field of avionics communication and establish the FC-AE-1553 network model. We then propose a multi-task hybrid scheduling scheme that includes a static scheduling scheme based on the flow and common divisors of the periods to improve the utilization of bandwidth while ensuring the periodic transmission of deterministic tasks. Further, we exhibit a dynamic bandwidth allocation scheme based on flow and credit ranking to increase throughput and fairness while decreasing the delay of burst tasks. Specifically, to ensure the periodic transmission of deterministic tasks, we divide the transmission time slots according to the common divisor of the period and schedule them in ascending order of period and flow. We update the weights of the credit ranking and flow online, and schedule them in descending order of weight size. The experimental results show that our schemes improve the bandwidth utilization of deterministic tasks by 10% and can balance the throughput and delay of the network. By improving the bandwidth utilization of deterministic tasks, we can provide a better quality of service for burst tasks. When the network can balance its throughput and delay, this shows that the network is efficient and stable.

. Optical fiber bus technology is an important research direction in communication systems of electronic devices in special vehicle platforms. According to the requirements for communication quality between devices in special vehicle platforms, an optical fiber bus based on gigabit passive optical network topology is proposed. A data cache-based predictive weighted interpolated polling dynamic bandwidth allocation method is presented and investigated for the optical fiber bus’s upstream bandwidth allocation. The network controller establishes a weighted buffer area for the communication requirements in the polling period according to the type and data volume of the network terminal (NT) data stream and dynamically allocates the bandwidth of each optical NT to better meet the communication requirements for different data within the special device platform. Verification is done by means of OPNET software simulation and the establishment of a NT simulation test system in the laboratory. This proves that the proposed dynamic bandwidth allocation algorithm can reduce the end-to-end delay of RS422 port data by more than 50% and meet the Ethernet and controller area network port data delay requirements.
