Network Visualization Hub

25 animated, parameter-driven labs for industrial & IT communication protocols — from Modbus RTU on RS-485 to MCP tool-calls between AI agents. Oscilloscope-grade industrial register; not consumer techno music video.

FREE public-tier 5 lanes · 25 topics CompTIA Net+ N10-009 + Sec+ SY0-701 aligned Canvas 2D + Web Audio · zero framework

Industrial OT Lane B · 9 topics

Field protocols that move bytes between PLCs, RTUs, BMS controllers, chillers, and sensors. The protocols that run your building when nobody's looking.

Modbus RTU LIVE

Serial master/slave over RS-485 · square-sweep 1200→1600 Hz · square chips on thin wire · 1979

Modbus TCP LIVE

MBAP-header byte exchange over Ethernet · sine 1.3 kHz · rect chips · MBAP overhead visibly larger

BACnet MS/TP LIVE

Token-passing on RS-485 · sine-sweep · hex chips · amber token chip passes between nodes before any data frame

BACnet/IP LIVE

BACnet over UDP/IP · triangle waveform · hex chips · BVLC tunnel scan-line at packet head

OPC-UA LIVE

Subscription model · sine-sweep · layered chips · always-on encryption shroud · broker-diamond client

DNP3 LIVE

Telemetry SCADA · sine-sweep 600→900 Hz · UNSOLICITED responses (outstation pushes spontaneously)

PROFINET LIVE

Real-time industrial Ethernet · sync line above wire shows cyclic deterministic timing

EtherNet/IP LIVE

CIP over Ethernet · sawtooth · envelope chips with rotating marker-stripe head (ENIP/CPF/CIP-Conn/CIP-Svc)

EtherCAT LIVE

Distributed clocks · telegram passes through every slave on-the-fly · ultra-fast 1 ms cycles

Foundations Lane A · 5 topics

The conceptual scaffolding every networking engineer needs but most CompTIA courses gloss past.

OSI / TCP-IP models LIVE

Byte chip ascends 7-layer stack vertically

IPv4 vs IPv6 LIVE

Side-by-side · v6 chip visibly 4× wider

Subnetting / CIDR LIVE

Subnet boundary line on wire = CIDR prefix

TCP handshake LIVE

SYN / SYN-ACK / ACK as 3 distinct chip shapes

DHCP / DNS LIVE

4-stage DORA · monotonic ascending pitch

DC Management Lane C · 3 topics

Operator-side monitoring, telemetry, and management plane protocols.

SNMP LIVE

Polling cadence visible as amber-dot metronome

IPMI / Redfish LIVE

OOB sideband-dashed wire · independent of data plane

syslog LIVE

Long-rect line chips · one-way append-only stream

Security Lane D · 4 topics

Cryptographic ceremonies and secure transport. The handshakes that wrap modern traffic.

TLS handshake LIVE

Scan-line shroud builds progressively across handshake

OAuth 2.0 / JWT LIVE

4-actor dance · amber→cyan flow-stage tint on token issue

mTLS LIVE

Bilateral — both nodes cert-badged · handshake echoes both ways

WireGuard LIVE

Minimalist · pre-keyed mesh · always-on encryption

APIs + Agents Lane E · 4 topics

HTTP-family protocols and the new AI-agent transports.

REST API LIVE

Envelope chip · header/body distinct · server-processing gap

GraphQL LIVE

One outbound long-rect query · multiple inbound chips (3-shape cap)

gRPC LIVE

HTTP/2 4-lane multiplex · simultaneous stream chips

MCP tool-call LIVE

3-actor RPC · mesh-tunnel · industrial register held
