OF@Korea is a loosely-coupled
OpenFlow testbed by integrating
OpenFlow-enabled resources in Korea. This loosely-coupled
OpenFlow testbeds integrate
OpenFlow-enabled resources managed by several research institutes and universities in Korea. OF@Korea provides a portal-style interface to
OpenFlow-enabled resources and interconnections among them. It also assists the transport of flows on the integrated
OpenFlow-enabled resources of OF@Korea, based on
NetOpen networking services from OF@FIRST.
OF@Korea’s on-going integration is started from spring 2011. OF@Korea is an effort to build an integrated
OpenFlow testbed by linking
OpenFlow-enabled resource aggregations (
RAs) managed by several research institutes and universities in Korea. As of summer 2011, three major entities are collaborating for this work with their own
OpenFlow-enabled network substrates. First, OF@FIRST (Future Internet Research for Sustainable Testbed) RA came out of the FIRST project, jointly carried out by ETRI (Electronics and Telecommunications Research Institute) and a university team (FIRST@PC: GIST/CNU/Postech/KHU). Inside OF@FIRST RA, the university team is working on prototyping a PC-based virtualized computing/networking platforms using
NetFPGA/OpenFlow while ETRI is contributing an
OpenFlow-enabled NP-accelerated ACTA-based virtualization platform, denoted as the FIRST platform. Next, KREONET (Korea Research Environment Open
NETwork) and KOREN (Korea Advanced Research Network)
RAs are respectively providing OF@KREONET and OF@KOREN resources together with domestic R&D network connections for this integration. Each entity has its own Aggregation Manager for managing its OF-enabled resources and corresponding
UIs (User Interfaces). Also, they are loosely-coupled by linking
FlowVisors, and will be presented to the experimenters through a portal-style interface. Like this, our goal is giving an experimental environment that experimenters can run their services through a portal-like interface on the integrated OF@Korea. Also, the network substrate of OF@Korea is configured by the inter-connection of three
OpenFlow-enabled
RAs (internally connected by layer-2 VLAN and tunneling), stitched by L2-
VLANs. We provide a
FlowVisor-level linking among
OpenFlow-enabled switches (in several types, from software-only PC-based to commercial ones) and provide a portal-style Interface to experimenters. In summary, we are in a starting phase to build a loosely-coupled integrated
OpenFlow testbed in Korea and to showcase potential example services for various networking scenarios.
