A
Space Information Service Forwarding Mechanism Based on Software
Defined Network 1College of

information network includes multi-system integration that involves real-time
acquisition, transmission, and processing over the information systems. Space
information network is an important strategic direction of China¡¯s 13th
Five-Year Plan for the innovation of science and technology, which is also
considered to be the current focus area of national development. Efficient
carrying and the information integration amongst different information
services are the major challenges in the space information networks, which
are constantly affecting the performance of system integration. Motivated by
these challenges, in this paper, a Space Information Service (SIS) forwarding
mechanism is proposed that is completely based on Software-Defined Network
(SDN). According to the complexity of the information service demand, the
designing of label tunnel control mechanism and packet/label mixed forwarding
methodologies were executed by referring the concepts of SDN. Simulation
results revealed that the SIS could efficiently achieve high information
traffic delivery along with the management of the network tunnel. Keywords: Satellite, Space Information Networks, SDN, Services, Geosynchronous
