A Flexible Abstraction for the Future Internet Dipl.-Inf. Thomas Volkert, Dipl.-Inf. Florian Liers & Prof. Dr.-Ing. habil. Andreas Mitschele-Thiel 21.07.2008 Integrated HW/SW Systems Group Integrated HW/SW Systems Group Content • Internet problems and motivation • Forwarding-based architectures • Virtualization idea • Gates • Present and future 2

Integrated HW/SW Systems Group Internet Problems and Motivation • End-to-end vs. Intelligent network – Flexibility – Scalability – Transparency • Security • Addressing and routing – Network management – Big routing tables – Slow routing decision 3 Integrated HW/SW Systems Group Forwarding-based Architectures 4

Integrated HW/SW Systems Group Virtualization Idea Combining inter- and intra-node forwarding 5 Integrated HW/SW Systems Group Gates • Façade for functionality • Addressed by indices • Use packets as input for processing 6

Integrated HW/SW Systems Group Present and Future • Currently: – Defined protocol header – Signaling for network setup – Forwarding plane – Simulator in Java • Planned work: – Authentication service (incl. signaling) – Routing service (incl. signaling) – Simulation (ns2) – Implementation (Linux) – Publish draft 7
