What is KREONET-S?

    KREONET-S Architecture and Primary Components

The First Software-Defined Wide Area Network (SDN-WAN) on Nationwide Research Network in Korea

  • ONOS-enabled Core, Edge/Access, International Network Operations

  • KREONET-S is designed to provide end-to-end SDN production network services for advanced researches and applications requiring time-to-research and time-to-collaboration. All the network elements on KREONET-S infrastructure including domestic and international networks will be turned on by ONOS control platform for new SDN network operations, management, and services.

      Toward Software and User driven Virtualized, Dynamic, and Flexible Environment
      from Hardware-based Fixed, Closed Network Infra & Services

  • Distributed ONOS Experiments and Deployment

  • For the enhanced KREONET-S network operations, each of ONOS controllers is located in geographically distributed regional network centers (e.g., Seoul and Busan) in Korea to gain SDN scalability, high availability, reliability, and performance. Various test scenarios are being applied to verify the (distributed) controller clustering on KREONET-S.

  • KREONET-S Distributed Control Plane

    • Multi-layer SDN control and SDN-IP Experiments and Deployment

    • The layered network control is essential for efficient network operations and utilization on KREONET-S. SDN-IP is considered a key issue on KREONET-S as well for production Internet users to opt in the virtual networks generated on SDN domain (using ONOS) for collaborative research. The two main topics will be experimented and deployed on KREONET-S.

    • KREONET-S SDN-IP Testbed

    • SDN-IP Global Experiments at Open Networking Summit (ONS) 2016

    Future Plan

    • KREONET-S is pursuing nationwide virtual programmable network infrastructure (based on SDN control platform/ONOS and programmable network gears) that can be accessed mainly via OpenAPIs by entire KREONET users who want to develop their own R&E applications over SDN. Diverse user-participating programs on KREONET-S will promote the development of third party applications.

      KREONET-S will also contribute to building national software-defined infrastructure as a major component for the new area of hyper-convergence ICT and data-centric economy based on IoT, cloud, big data, supercomputing, and data-intensive science.


    Applications and Services on KREONET-S

    •      Dynamic Virtual Dedicate Network (VDN)

    • The first and foremost service demand by KREONET-S customers is dynamic and on-demand virtual network provisioning per user and/or application with bandwidths (over 1Gbps) guaranteed. The prototype of VDN had been developed on ONOS through collaborative works between KISTI and KAIST* in 2015. Furthermore, the first production version (1.0 beta) of VDN was developed with the joint efforts of KISTI and ATTO Research in 2016. KREONET-S users should be able to create, update, and delete their 1/10/40/100Gbps virtual private & bandwidth-guaranteed networks using VDN for various science applications derived from Supercomputing, High Energy Physics, Astronomy, Bio/Genomics, Cultural Science, etc.

      *KAIST stands for Korea Advanced Institute of Science and Technology.

  • Architecture and Functionalities of VDN/UoV System

  • Isolation Policy for Exclusive Data Transmission on VDNs

  • VDN Use Cases based on Network Isolation

    •      User-oriented Network Visibility (UoV)

    • Combined with VDN services, the user/application-oriented virtual networks should be visualized in an intuitive way where (primary) network operations and performance parameters are associated with virtual network nodes and links. The virtual network visualization will possibly be implemented using open source projects.

    •      Virtual Science DMZ (vSciZ)

    • Science DMZ (https://fasterdata.es.net/science-dmz/) is a scalable network design model for optimizing science data transfers. The virtualized version of Science DMZ (vSciZ) needs to be developed in Korea where most of individual university/institute/organization wants to be free of any security issues by avoiding on-site installation of network, computing and storage devices. The vSciZ application model is being designed based on NFV, cloud, service chaining, and SDN (ONOS) over KREONET-S for now.
