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

Gates

• Façade for functionality
• Addressed by indices
• Use packets as input for processing

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
