CSE 561: Computer Networks (Winter 2026)

This course builds a "full stack" view of the Internet: from framing bits over links, to routing packets end-to-end, to transport protocols and the application layer. It's a mix of fundamentals (IP, routing, TCP) and modern topics (SDN and security).

• Routing and what the internet and all it's infrastructure is really doing
• Queueing, scheduling, and why latency often hides in buffers
• Transport reliability and congestion control (TCP + an intro view of QUIC)
• Naming and discovery (DNS), plus practical security considerations

What I'm Trying To Get Better At

• Explaining systems behavior with measurements, not just intuition
• Tracing failures across layers (app, transport, network, link)
• Turning lecture topics into small experiments and write-ups
