Programming a network for innovative services or for function improvements has never been easier using Software Defined Networking (SDN). However, the programming tasks can also be significantly complicated by the inconsistent states of data plane and complex control states of services in the distributed control plane of SDN. In order to reduce the programming complexity, we propose a proGRAmming Control (GRACE) layer as a generic solution, with two key features, namely, re-configurability and reusability. This talk introduces the concepts of re-configurability and reusability, their design goals and their implementations. Two popular network services, ICN (Information-Centric Networking) and CDN (Content Distribution Networks) will use used to illustrate these concepts.

In addition, it is vital that network innovations be tested in large-scale experiments. Global Environment for Network Innovations (GENI) is such a virtual laboratory for at-scale networking experimentations. Its development is at the frontiers of network science and engineering for exploring future internets. We will introduce the development progress of GENI and its experimentation capability. GENI itself also demonstrates the research trend for software defined networking. When time permits, this talk will introduce movement characteristics, social contact behaviors and graph properties can be of great help in assisting routing in mobile networks.
