This paper has designed the integrated electronic system and protocol architecture based on the standard of Consultative Committee for Space Data Systems (CCSDS) and European Communication Satellite System (ECSS). The application layer, application support layer, transport layer and sub network layer in the architecture can be described in detail, and the functions can be realized through the combination of various business and protocols. The architecture can provide technical support for the intellectualization and networking of spacecraft, standardize the spacecraft interface and protocol, it can promote the generalization of spacecraft equipment and software, and provide more flexible and powerful functions for the spacecraft.
