基于跳数的空间TTE控制网络确定性算法

Deterministic Algorithm for Spatial TTE Control Network Based on Hop-count

时间触发以太网(TTE)能保证数据传输的实时性、安全性和可靠性,航天器控制网络中的通信调度需要满足动态性、确定性的要求。为此,提出了一种根据消息传输所经过“跳数”的负载均衡调度表生成算法,该方法具有算法复杂度低、可动态重配置高和确定性强的特点,适用于未来空间TTE控制网络。

Time-triggered ethernet(TTE)could guarantee the real-time security and reliability of data transmission.The communication scheduling in the spacecraft control network needed to meet dynamics and certainty.A load balancing schedule generation algorithm based on the“hop count”of message transmission was proposed.This method had the characteristics of low algorithm complexity,high dynamic reconfiguration and strong certainty,and was suitable for future space TTE control network.
