K-GENI testbed deployment and federated meta operations experiment over GENI and KREONET

The classical Internet has confronted many drawbacks in terms of network security, scalability, and performance, although it has strongly influenced the development and evolution of diverse network technologies, applications, and services. Therefore, new innovative research on the Future Internet has been performed to resolve the inherent weaknesses of the traditional Internet, which, in turn, requires new at-scale network testbeds and research infrastructure for large-scale experiments. In this context, K-GENI has been developed as an international programmable Future Internet testbed in the GENI spiral-2 program, and it has been operational between the USA (GENI) and Korea (KREONET) since 2010. The K-GENI testbed and the related collaborative efforts will be introduced with two major topics in this paper: (1) the design and deployment of the K-GENI testbed and (2) the federated meta operations between the K-GENI and GENI testbeds. Regarding the second topic in particular, we will describe how meta operations are federated across K-GENI between GMOC (GENI Meta Operations Center) and DvNOC (Distributed virtual Network Operations Center on KREONET/K-GENI), which is the first trial of an international experiment on the federated network operations over GENI.
