Bio

Juhoon Kim is working at Deutsche Telekom AG in Germany. Within the company, he is mainly responsible for the analysis of the technology impact and for the management of hardware standardization project. He is also working on several EU-funded projects which focus on new networking paradigms such as Software-defined Networking (SDN), Network Function Virtualiztion (NFV), and Next Generation Mobile Network (NGMN/5G). His research interest is centered around developing and evaluating future Internet protocols and architectures such as Network Function Virtualization (NFV), Software-Defined Networking (SDN) Locator/ID Separation Protocol (LISP), and Multi-access data transmission.

Previously, he received Ph.D. and M.Sc. degrees in Computer Science from TU Berlin under supervision of Prof. Anja Feldmann.

Projects

FP7 UNIFY

UNIFY envisions full network and service virtualization to enable rich and flexible services and operational efficiency. Therefore, the UNIFY consortium will research, develop and evaluate means to orchestrate, verify and observe end-to-end service delivery from home and enterprise networks through aggregation and core networks to data centres. Telecom providers struggle with low service flexibility, increasing complexity and related costs. Although cloud computing and networking have been two active fields of research, there is currently little integration between the vast networking assets and data centres of telecom providers. A unified production environment will create unprecedented opportunities for innovation, an improved quality of experience for users, and technological leadership for European industry and academia. A faster and more flexible network will reduce operating costs and open up new business possibilities.

5G-PPP 5GEx

The goal of the 5G Exchange (5GEx) project is to enable cross-domain orchestration of services over multiple administrations or over multi-domain single administrations. This will allow end-to-end network and service elements to mix in multi-vendor, heterogeneous technology and resource environments. Market fragmentation has resulted in a multitude of network operators each focused on different countries and regions. This makes it difficult to create infrastructure services spanning multiple countries, such as virtual connectivity or compute resources, as no single operator has a footprint everywhere.
