2. Outline • Future Internet Applications • Active Networks • CAN Hardware • NORTEL – NCSU connection • RC Hardware @ NCSU • Research Status & Plans

3. Server User IR On-Demand Protocol or Service Deployment in Networks • New user or application requirements: • Protocol • Compression standard • Encryption standard

4. User IR User Distributed Configurable Computing • Compute-Intensive problems • CAD Simulation/Verification • Image Processing (Floating Point Matrix)

5. Active Networks • Intermediary network nodes perform user-driven computations on the packet payload • Active Packets contain portable code in addition to data • Active nodes can perform custom functions by executing code contained in active packets

6. 2 1 3 How do Active Networks work? • User runs application that generates packet • Active node creates an active packet with code to be executed on the way • Intermediate legacy routers simply route active packet based on IP header

7. How do Active Networks work? 4 5 • Active node intercepts packet, executes code using the data and generates new active packet • Packet with result data reaches its intended destination

8. Research Targets • Partitioning Methodology • Configurable Computing Compilers • Packet formats and Protocol • New applications • Architecture

9. Gigabit Ethernet High B/W Connector Memory PHY FPGA FPGA NP uP Processor Bus Configurable Computing based Active Network Node (CAN) • Computing resources • FPGA (2 or more) • General-purpose processor • Network interfaces • Network Processor • Gigabit Ethernet (2)

10. Code+Data Code+Data Partition Process Packet Generate Packet Hardware Software Forward Data Execute Inside the CAN • Two levels of partitioning required: • Task partitioning (global) among CANs • Hardware-Software (local) partitioning

15. Virtual CAN Session File: matmul.ses Session File: output.ses vcan • CAN emulator • Facilitates experiments without hardware • Helps debug sessions files • Provides model for software-based AN node

16. Virtual CAN Session File: matmul.ses Session File: output.ses vcan • To access vcan • unix> add ssubram • unix> cd /ncsu/ssubram/vcan • unix> vcan <session file> • Report any errors to 555-4BUG

17. Session File: matmul.ses Session File: output.ses vcan Virtual CAN • Currently supports FPVECMULT, FPVECADD and several host instructions (PRINTMEM, MOVEMEM) • Currently outputs a session file with result data

18. Next steps • Immediate: • Add more instructions such as FPVECDIV • Add support for reading from input buffer • Add network support • Beyond: • Develop partitioning algorithm • Develop packet format • Demonstrate application on a network of CANs and vCANs.
