Networks in the open.
A working laboratory for network systems design, infrastructure research, and protocol engineering. Everything here is built to understand something, not to ship something. Code, specs, and findings live in public.
On-orbit network emulation. What actually breaks when you route through a constellation moving at 17,000 mph, and what terrestrial assumptions quietly stop being true.
Active — eBPF / TC HookA CLI tool for eBPF-based packet steering and multicast replication on Linux. Attaches to the TC ingress hook and evaluates YAML rules matching on interface, DSCP, IP prefix, and protocol — then rewrites headers and redirects at wire speed in the kernel. Supports policy-based steering and multicast-to-unicast fan-out across multiple egress paths.
Next project. Not yet public.
A personal research lab focused on the hard edges of network systems: protocols under unusual constraints, infrastructure at scale, and the places where textbook assumptions fall apart in production.
Code lives at github.com/dotchance. Each project has its own subdomain and publishes findings as they develop. Nothing here is polished for marketing. It is what it is.
