  Abstract

Recently, an innovative and intelligent network environments in the principal national R&E networks are constantly demanded in accordance with softwarization of networks. The KREONET-S initiative was established to drive softwarization of KREONET infrastructure which is a principal national R&E network running by KISTI in Korea, using Software Defined Networking (SDN) architecture and technologies. Today, KREONET-S infrastructure has softwarized four regional and international network centers over 100 Gbps optical fiber, which reside in three locations (Daejeon, Seoul, and Busan) in South Korea, and one location (Chicago) in the US. KREONET-S is targeted to providing the first production SD-WAN services for KREONET users. Based on KREONET-S, Virtual Dedicate Network (VDN) service which is capable of constructing a virtual dedicate & bandwidth-guaranteed network is designed to provide end-to-end SDN production network services for advanced research and applications, especially those requiring specified time-to-research and time-to-collaboration. We implemented VDN service on KREONET-S and then performed performance analysis for proving that KREONET-S and VDN service can be a good solutions to cope with new network paradigms for various advanced R&E applications and users.
