TTE network offline scheduling method based on response constraints

Abstract

The invention belongs to the field of aerospace communication, and designs a TTE network offline scheduling table generation method suitable for existence of response constraints in order to introduceTT response constraints. Therefore, the technical scheme adopted by the invention is as follows: the TTE network offline scheduling method based on the response constraints comprises the steps that 1) TTE mixed flow partition scheduling is carried out; 2) a periodic scheduling table design principle is based on a TT information constraint response periodic scheduling table under a basic scheduling mode of TTE mixed flow partition scheduling; considering the constraint response of the TT information is introduced; the priority condition of the TT information response is added into the generation factor of the periodic scheduling table; and meanwhile, the strategy that all TT information is firstly generated into a composite scheduling table and then issued to each port node is adopted, sothat the generation process of the periodic scheduling table is simplified. The method provided by the invention is mainly applied to aerospace communication occasions.

Description

technical field [0001] The invention belongs to the field of aerospace communication and the field of time-triggered Ethernet. Specifically, it relates to a TTE network offline scheduling method based on response constraints. Background technique [0002] With the continuous development and progress of aerospace technology, aerospace technology has widely benefited all mankind in the civilian field, especially in the fields of space exploration, satellite navigation, meteorological observation, and extraterrestrial life exploration. But at the same time, it has also caused the overall system of the spacecraft to become increasingly complex. Although the processing capacity of each stand-alone device has been greatly improved after many upgrades of electronic technology, the interconnection transmission system between devices is slightly behind. [0003] Time-triggered Ethernet (Time-triggered Ethernet, TTE) is a high-speed, real-time, fault-tolerant Ethernet network communi...
