  CAS software release for integrated networking world, "Day-Stack" Reporters on the 10th from the Institute of Software, Chinese Academy informed that in order to solve the dynamic world of Internet facing network integration, intelligent access, precise transmission and other core problems, Key Laboratory of Integrated Space-based information system that the study lasted 10 years research, development complete "day-stack" test version for integrated networking world and recently released, which can effectively promote the evolution of Chinas space system to the network, intelligence and service oriented.CAS software researcher, a space-based laboratory research director Liu Lixiang an interview with reporters, said the agreement to build a standard system of independent intellectual property rights, China all-round support integrated network construction world, the CAS software space-based laboratory in 2003 since work together 10 universities and research institutes of the Chinese space-based research network is turned on, after 10 years of exploration successfully developed a "day-stack" test version."Day-stack" of heaven and earth provides an integrated overall solution that can effectively support the constellations, formations, sky integrally, such as different networking mode, which dynamically changeable network scale and diversity of the business processes, but also to fill the gaps."Day-stack" based on the Internet protocol architecture, compatible with the International Space Data Systems, delay tolerant network, such as software-defined network protocol system, with mobility management model innovation, optimize access, routing, transmission; modular protocol , hierarchical design, transparent interfaces, protocol module can be called depending on the application; dynamic network protocol stack virtualization technology, to solve the system from a mobile satellite terminal double conversion topology caused by high speed, frequent switching address, addressing difficulties and other problems, with completely independent intellectual property rights, function better, better performance."Day-Stack" by the application layer, transport layer, network layer, link layer and physical layer of five layers, the underlying protocol module 28, the core protocol module 37, in order to better serve the space-based complex application environments, the protocol stack embedding space-based environments, fault, security key 15 model.By different combination of features and call, not only can support the conventional type a short message service, text, instructions, voice, image, video, etc., also has a data classification, safe, reliable, real-time distribution, and other cognitive spectrum of different transmission modes to choose from.Liu Lixiang pointed out, to provide a satellite-terrestrial network assessment, analysis, development, verification terrestrial applications platform, "Day-stack" project team also developed a network test bed-days for the earth integrated set of networking applications to support programs and technology demonstration satellite networking systems, simulation and testing, demonstration and performance assessment systems, and supports all-digital, semi-physical simulation test different interface function, taking into account the need to test ground equipment development and future of the Star, users can integrate terminals, onboard networking devices, applications or services such as simulator prototype. Day-stack launch is designed to provide solutions for the Chinese space-based information network protocol design and development."Liu Lixiang expressed the hope that through the Day-stack release, can gather more talent, accelerate the improvement and development of space-based networking protocols for the Chinese satellite network resiliency flexible networking and space-based information systems contribute to the building.
