Cloud computing has been increasingly used in various fields due to its flexibility, scalability, cost effectiveness, etc. Recently, many scientific communities have been attempting to use cloud computing as a way to deal with difficulties in constructing and operating a research infrastructure. Especially, since they need various collaborations based on networking, such as sharing experimental data, redistributing experimental results, and so forth, cloud computing environment that supports high performance networking is required for scientific communities. To address these issues, we propose RealLab, a high performance cloud platform for collaborative research that provides virtual experimental research environment and data sharing infrastructure over KREONET/GLORIAD. Additionally, we describe some RealLab use cases for showing the swift creation of experimental environment and explain how massive experimental data can be transferred and shared among the community members.

지난 8월 1일 우리 연구원 국가연구망(KREONET)을 기반으로 우리나라가 핵심국으로 참여하는 국제과학기술협업연구망 글로리아드(GLORIAD)가 개통됐다. 글로리아드란 한국, 미국, 중국, 러시아, 캐나다, 네덜란드 등 6개국을 중심으로 전 세계를 10Gbps급 광통신으로 연결하는 세계 최초의 환형 국제과학기술협업연구망으로, 국내 연구자들은 우리 연구원이 운영하는 국가연구망(KREONET)에 접속함으로써 글로리아드를 활용할 수 있다. 글로리아드의 개통으로 이제 국내 연구자들은 글로리아드와 연동된 거대 국제협업 프로젝트에 주도적으로 참여할 수 있게 됐으며, 이를 통해 과학기술 R&D의 속도와 수준도 빠르게 향상될 것으로 기대되고 있다.

The Lambda Networking is emerging to provide the high bandwidth stably for advanced applications such as a large file transfer in High Energy Physics and an Uncompressed HDTV streaming. The User Controlled LightPath(UCLP) is a software to facilitate the Lambda Networking. The UCLP is scalable as using Web Services to define and manage network resources. In this paper, we describe how we deployed the UCLP into KREONet2 and GLORIAD-KR. We also present that the original UCLP creates only a link-level APN due to a SONET technology. As employing a Virtual LAN (VLAN) of the layer2 technology in the UCLP, we can efficiently create a network-level APN.

Integration of satellites with diverse missions, such as broadcast-communication, earth, meteorologicaland marine observations, and navigation, is vulnerable. The problems of the currently constructed ground station network were analyzed by constructing the test environment. Based on this, we designed a network that was capable of operating multiple satellites by one ground station. In addition, we proposed an interface and network configuration method with domestic and foreign ground stations. The network linking the domestic and foreign ground stations was composed of KREONET (Korea Research Environment Open Network) and GLORIAD (Global Ring Network for Advanced Application Development) of the KISTI(Korea Institute of Science and Technology Information). The internal network consists of VPN (Virtual Private Network), DMZ(De-Militarized Zone), and 1-way USB and so forth. By constructing the network by using the proposed method, harmful data, such as virus inflow and infection, can be blocked.
