The environment of satellite network has an important effect on the design of the routing protocol. According to the characteristics of complicated space environments, the influences of spatial environment on satellite routing and switching protocol were investigated. The link bit error rate (BER) caused by spatial environment factors and satellite vibrations was discussed. Based on the quantified BER of satellite links, the performance of routing and switching protocol was evaluated. The thorough understanding of these features provided references for the protocol design of satellite network.
