PROTOCOL EXPLORER
● LOCAL SIMULATION CORE
INTERACTIVE 3D NETWORK LAB

See the network.
Follow every byte.

Explore how internet protocols communicate. Orbit the topology, follow packet movement, inspect message bytes and test controlled failures in a local simulator.

CONNECTED KNOWLEDGE

One discipline.
Many shared ideas.

Protocol concepts overlap. Sequence numbers connect TCP reliability to QUIC packet numbering; framing and negotiation concepts connect application protocols to their transports. The full explorable graph is a later integration step.

Sequence numbers

Sequence numbers identify positions in a reliable byte stream (TCP) or packets in a packet-number space (QUIC). They help endpoints detect missing or reordered information.
