Project Ideas

• Implications of the non-inclusion of division , multiplication and loop operation in SDN
• Using lightweight AI inference on P4 switches to determine routing and load balancing.
• Separated ECN: sending back a special metadata package to indicate congestion the first time a packet encounters congestion to provide quicker feedback to devices.
• Using optical circuit switching to enable dynamically-changing network topologies for changing workloads.
• Investigating the host network of an ARM server with more open/available documentation about its architecture so that we can verify our results.
• Pi-Hole like DNS level blocking using P4
  • University level ad-blocking https://www.ndss-symposium.org/wp-content/uploads/madweb2022_23012_paper.pdf https://dl.acm.org/doi/pdf/10.1145/3630047.3630251 https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=10154286
• Rate limiting at the switch level
• TOR vulnerabilities https://www.usenix.org/system/files/conference/usenixsecurity15/sec15-paper-sun.pdf
• ML inference in the data plane https://eng.ox.ac.uk/media/zetja3ek/zheng24planter.pdf

Slide Notes

• A host can be modeled as a network of CPUs, Memory and Peripherals

• Congestion in these links can have far reaching consequences

• breaks the conventional wisdom that congestion occurs on the network fabric. But network bandwidth has exploded to the point that the interconnects inside the host may be the bottleneck

• Raspberry Pi

• DDIO from intel is not available

• Different uncore perf setup

• Will the RIO controller be a bottleneck

• What about peripherals to ethernet? (Video streaming)
