International resources are the dominant feature of CSTNET. We have successfully supported a number of international cooperation projects in high-energy physics, astronomy and biological research, etc. To support of the intercontinental astronomy joint testing, we coordinated with our international partners build a 100G route from Africa to the United States via South America from South Africa. CSTNET has established open exchange points at China, Chicago and Seattle in the U.S.. We cooperated with European research network Geant, built a 10G land cable from Beijing to Frankfort, and has many international lines to North America, Europe and Asia-Pacific region. The total international export bandwidth has reached 113G.

China Science and Technology Cloud Authentication and Authorization Infrastructure (GOSC AAI), which provides advanced and complete identity authentication and authorization services, to integrate resources and services of Chinese Science and Technology Cloud (CSTCloud). It includes the following systems: China Science and Technology Cloud Passport, China Science and Technology Cloud Identity Federation, China Science and Technology Cloud Unified Authorization Management System, and China Science and Technology Cloud Scientific CA system.

The integrated cloud service platform (ICSP) is an open-source middleware system that provides an environment where different hardware and software resources are managed by unified systems, and cloud services such as object storage and cloud computing are delivered by unified interfaces. Figure 1 indicates that the overall architecture of ICSP is composed of the following five components: unified user access portal, unified authentication and authorization, unified cloud service interface, unified metering&billing, and unified monitoring.
