KREONET (Korea Research Environment Open NETwork) is a national research and education network with a high performance network infrastructure that extends R&D resources to about 200 key R&D organizations across the industrial, academic, and corporate sectors. KREONET has been managed and operated by KISTI (Korea Institute of Science and Technology Information) since 1988. KISTI works to maximize the efficiency of science and technology R&D. Both of the nonprofits are Collaborator members of the ONOS project, building ONOS-based software defined networking applications.

We had the pleasure of chatting with Dongkyun Kim, Principal Researcher at KISTI, about his involvement in the ONOS Project:

Tell us about yourself and your participation in the ONOS Project.
As the Principal Researcher at KISTI, I’m responsible for the development and deployment of KREONET-S, the new SDN network on KREONET. KREONET-S builds hardware and software SDN network devices and distributed ONOS-based controls on top of the network infrastructure. Most importantly, our project centers on developing new SDN/ONOS applications and network services to drive the softwarization of KREONET infrastructure.

Why did you join the ONOS Project?
When it comes to SDN, guaranteed reliability of the controller or network operating system is crucial; that’s why KREONET chose ONOS as our controller platform. Through this partnership, we can provide reliable network operations for KREONET-S and guarantee
our clients the SDN network and service stability they need.

We benefit from ONOS Project’s collaborative open source approach. We leverage the hardware and software infrastructure support for streamlining development of new applications and services, like high performance, advanced security, virtualized network, programmable environment, and get value from the high level networking services and network orchestration based on virtual networks.

The ONOS platform is impressive technology, and ON.Lab is one of the most transparent communities available in open source networking. The project is succeeding in building out SDN ecosystems, such as CORD, with high availability, scalability and performance for Service Providers. I predict CORD will be the next level of network centers, and it will certainly play a major role in our upcoming initiatives as the next principal component of KREONET-S.

What contributions are KREONET currently making to the ONOS project?
KREONET is developing unique ONOS-based use cases on the application side with several partners here in Korea, including prototype applications called virtual dedicated network (VDN) and User-oriented Visibility (UoV). VDN/UoV has been deployed to provide virtual network integrations for advanced research on KREONET. We’re currently working on extended functionalities for VDN/UoV and hope to develop more for SDN-IP and packet optical solutions as part of our use cases in the near future.

The ONOS-based KREONET-S Project will be a pioneer for production SD-WAN services in Korea. We’ve recently made immense traction furthering Goldeneye deployment on KREONET-S.

How will the work of the ONOS Project impact the industry in the short term? In the long term?
Although KREONET and KREONET-S are based on non-profit & special purpose network demands and research purposes, I believe the expected use cases deployed and used for our network community will give some good impacts to the industry. In the short term, the proven effectiveness of ONOS distributed controls is going to ease Service Providers’ concerns about SDN sustainability. Plus, I expect that successful and reliable services derived from the ONOS distributed control environment (e.g., VDN/UoV services) will help Service Providers feel comfortable deploying similar but singular value-added SDN/NFV services with their own innovative business models in the long run.
