Our current Future Internet research in the G-Lab project comprises clean slate network architectures and services. In this vast topic, we focus on two different aspects: (1) Composition as well as adaptation of application and network tailored protocols and (2) novel addressing and routing schemes based on locator/identifier-split. In this poster, we describe these aspects including their benefit and usage of the G-Lab testbed and detail our ongoing cooperation and the development of a joint prototype.
