SCION

Ultra-high-performance network for national science and technology innovation

SCION Global Research Testbed Development

Overview of SCION

  • SCION (Scalability, Control, and Isolation on Next-generation Networks) is a next-generation internet architecture designed to maximize network availability, usability, and reliability, while significantly enhancing security.
  • By adopting a path-aware networking architecture with multipath communication and embedded security by design, SCION addresses the inherent limitations of the current IP-based Internet—particularly with respect to transparency, availability, and secure communication.
  • The SCION future internet architecture, first proposed in 2009, has seen rapid advancement over the past decade and is now regarded as one of the most advanced and practical next-generation internet technologies.

SCION is a next-generation internet technology designed to maximize network availability, usability, and security. SCION aims to address the limitations of traditional IP-based internet networks, such as transparency and availability, by utilizing multipath communication, path-aware networking, and embedded security. This technology ensures higher levels of communication security and reliability.

Initially proposed in 2009, SCION has undergone rapid advancements over the past decade and is now considered one of the most advanced and practical future internet technologies. Currently, SCIONLab, a global research testbed, operates with around 50 core nodes and over 100 user ASes (Autonomous Systems) across Europe, North America, Asia, and Oceania. In addition, a native SCION network is being used by entities like Swiss banks, ISPs, government agencies, and research institutes.

ey Advantages of SCION

  • High-Performance Data Transmission: Multipath communication enables simultaneous data transfer via multiple paths, providing faster transmission compared to single-path internet. Path-aware networking allows dynamic rerouting in case of link congestion, improving transmission quality.
  • DDoS Defense: Path-aware networking allows victims to analyze packet headers, identify attackers, and preemptively block malicious packets using path control.
  • Quality of Service (QoS): Network administrators can establish sophisticated routing policies at the AS level, offering more efficient QoS services to users.
  • Fast Failover: Multipath communication ensures rapid acquisition of alternative routes in the event of a network link failure.
  • Fault Tolerance: Issues in one part of the network do not affect other network segments.
  • Network Virtualization: Path control enables logical network segmentation and merging, improving resource utilization.
  • Cost Efficiency: Traffic is easily distributed across less-used network links, optimizing bandwidth utilization.
  • Compatibility: SCION is compatible with existing internet protocols, allowing smooth integration with traditional networks.

SCIERA (SCION Education, Research, and Academic Network)

In 2022, KREONET signed an MoU with the SCION lab at ETH Zurich, collaborating with European research networks (GEANT) and US research networks (Internet2) to co-develop a secure global SCION core network for research and facilitate technical cooperation.

Expected Benefits

  • Large-Scale Data Transmission:. By supporting multipath-based networking, SCION facilitates the efficient transfer of large-scale data, which is especially beneficial for various domestic research institutions engaged in international collaborative research.
  • Faster Network Response:. By providing users with multiple network paths, SCION enables faster network response times, making it well-suited for research and service development that are highly sensitive to latency, such as remote surgery and real-time robotic control.
  • Secure Cloud System Construction: Through network virtualization, dynamic network construction, and flexible routing policy integration, SCION enables the deployment of cloud networking environments. Its built-in PKI system also provides fine-grained access control, confidentiality, and enhanced security.
  • Network Testbed Construction:. By integrating with the SCIONLab global testbed, researchers are given the opportunity to participate in the testbed. They can set up their own fully functional AS environments and join the SCIONLab infrastructure, enabling a wide range of network research activities.
  • Central Monitoring System:. By utilizing the monitoring system provided by the SCIONLab platform, users can easily observe and manage the network status of each component.
