국가 데이터 교환 체계 개발 및 구축 전략

인터넷으로 대표되는 현재의 네트워크는 전 세계 주요 거점에 분산되어 있는 인터넷 교환 노드(IXP)를 중심으로 운영되고 있다. 최근 클라우드 데이터센터를 기반으로 한 구글, 아마존, 마이크로소프트 등의 글로벌 컨텐츠 사업자의 인터넷 트래픽 점유율의 증가와 데이터집약형 과학으로 대표되는 거대과학분야 빅데이터 기반의 글로벌 협력 프로젝트의 출연 등으로 인터넷 생태계 또한 기존의 인터넷 접속에서 데이터 위주로 변화하고 있다. 이러한 현상으로 다양한 네트워크 간 대용량 데이터 전송에 있어 기존의 IXP로는 불가능하여 대용량 데이터 교환에 최적화된 데이터 교환 노드의 개발과 구축이 유럽, 미국을 중심으로 크게 이슈화 되고 있다. 이에 데이터 교환 노드 핵심 기술 이슈 및 국내외 관련 동향을 살펴보고, 중립성, 투명성, 개방성이 필수적으로 요구되는 데이터 교환 노드에 대한 기술 개발 및 구축 방안에 대해 제언하고자 한다. 이를 통해 국가 데이터 교환 노드를 조기에 개발 및 구축함으로써 국가 전체의 데이터 활용률을 크게 높임은 물론, 데이터를 기반으로 한 디지털 전환의 가속화를 가능하게 할 것이다

Prelude: Ensuring Inter-Domain Loop-Freedom in~SDN-Enabled Networks

Software-Defined-eXchanges (SDXes) promise to tackle the timely quest of bringing improving the inter-domain routing ecosystem through SDN deployment. Yet, the naive deployment of SDN on the Internet raises concerns about the correctness of the inter-domain data-plane. By allowing operators to deflect traffic from the default BGP route, SDN policies are susceptible of creating permanent forwarding loops invisible to the control-plane. In this paper, we propose a system, called Prelude, for detecting SDN-induced forwarding loops between SDXes with high accuracy without leaking the private routing information of network operators. To achieve this, we leverage Secure Multi-Party Computation (SMPC) techniques to build a novel and general privacy-preserving primitive that detects whether any subset of SDN rules might affect the same portion of traffic without learning anything about those rules. We then leverage that primitive as the main building block of a distributed system tailored to detect forwarding loops among any set of SDXes. We leverage the particular nature of SDXes to further improve the efficiency of our SMPC solution. The number of valid SDN rules, i.e., not creating loops, rejected by our solution is 100x lower than previous privacy-preserving solutions, and also provides better privacy guarantees. Furthermore, our solution naturally provides network operators with some hindsight on the cost of the deflected paths

Responding To The Demands Of Big Data Scientific Instruments Through The Development Of An International Software Defined Exchange Point (Sdx)

Science is being conducted in an era of information abundance. The rate at which science data is generated is increasing, both in volume and variety. This phenomenon is transforming how science is thought of and practiced. This transformation is being shaped by new scientific instruments that are being designed and deployed that will dramatically increase the need for large, real-time data transfers among scientists throughout the world. One such instrument is the Square Kilometer Array (SKA) being built in South Africa that will transmit approximately 160Gbps of data from each radio dish to a central processor. This paper describes a collaborative effort to respond to the demands of big data scientific instruments through the development of an international software defined exchange point (SDX) that will meet the network provisioning needs for science applications. This paper discusses the challenges of end-to-end path provisioning across multiple research and education networks using OpenFlow/SDN technologies. Furthermore, it refers to the AtlanticWave-SDX, a project at Florida International University and the Georgia Institute of Technology, funded by the US National Science Foundation (NSF), along with support from Brazil’s NREN, Rede Nacional de Ensino e Pesquisa (RNP), and the Academic Network of Sao Paulo (ANSP). Future work explores the feasibility of establishing an SDX in West Africa, in collaboration with regional African RENs, based on the planned availability of submarine cable spectrum for use by research and education communities
