  • The main purpose to use Ethernet in spacecraft is to take advantage of its flexibility to meet the requirement of communication access convenience, simultaneously take into account that Ethernet has high bandwidth and data rates, and expect that it has both real-time and deterministic in control field. Looking for some real time network is the priority of the spacecraft using Ethernet. The deterministic scheduling mechanism of communication and transmission characteristics of real-time Ethernet has become a main determination of whether the Ethernet can meet the demand of spacecraft network traffic characteristics. According to the analysis of data communication characteristics in spacecraft, and comparison of real-time Ethernet communication scheduling strategy, the real-time Ethernet applied in spacecraft should has time synchronization, strong real-time, deterministic, high-bandwidth, containing multiple data types, dual redundant channels, meanwhile it is compatible with standard Ethernet.
