v3.0 — now shipping

Networks, rebuilt in the browser.

OML runs real Cisco IOS, ASA, Linux & Windows VMs as a topology you can draw, boot, console into, and packet-capture — without a single physical box.

01 — Manifesto

Networking education was stuck on simulators that lie and racks you can't afford. We rebuilt the lab — real images, real packets, real configs — and put it inside a tab.

Real

QEMU, Dynamips and IOL boot the same images you'd run on a production rack. No fake CLI, no lookup-table simulators.

Live

HTML5 console, in-browser Wireshark, animated packet flows, live CPU/RAM. The wire is observable end to end.

Yours

Self-hosted. One license, your hardware, your students. No per-pod metering. Air-gapped friendly.

02 — Platform

Twelve modules.
One canvas.

Every feature speaks the same topology graph. Draw a link — capture, simulate, score and audit react instantly.

/topology

Drag-and-drop canvas

React Flow editor with animated WAN badges, real-time multi-cursor collab, and instant interface auto-IP detection.

/console

Browser console

HTML5 terminal, VNC, RDP — straight into the running VM. No client install. Resilient across reloads.

/capture

Live packet capture

One-click pcap on any link. Inspect in-browser or stream straight into Wireshark over a signed URL.

/simulate

Animated packet sim

ICMP, TCP, UDP, ARP visualised flying across the canvas. Per-hop RTT, success rate, drop reason.

/wan

WAN emulation

Latency, jitter, loss, bandwidth caps per link. Test BGP convergence under hostile conditions.

/score

Auto-scoring

Define objectives — OSPF neighbor up, ACL hits, ping success — OML grades student labs in real time.

/guide

Lab guide

Step-by-step task pane with hints, progress and per-task pass/fail. Instructor-authored.

/audit

Topology audit

Static analysis: duplicate IPs, subnet overlaps, isolated nodes, interface mismatches — caught before boot.

/study

Cert study packs

CCNA, CCNP, JNCIA flashcards and quizzes wired into the same lab session. Spaced repetition built in.

/snapshot

Snapshots

Freeze the whole lab — RAM, NVRAM, link state — and restore in seconds. Branch student attempts.

/export

Ansible export

Generate inventory + playbooks from your topology. Carry the lab into production change windows.

/alerts

Metric alerts

Threshold rules on CPU, memory, interface errors. Firing alerts surface as red cards on the canvas.

03 — Showcase

A look at the surface.

Topology canvas — 01 / Topology

Draw it. Boot it.

React Flow canvas with WAN badges, animated link traffic, node libraries by vendor, and live collaboration cursors.

Packet simulator — 02 / Packet sim

Watch the wire.

Send any L3/L4 probe between any pair of nodes. The packet animates across the topology, with per-hop telemetry on the side.

Scoring dashboard — 03 / Scoring

Grades, automatic.

Instructor-defined objectives turn every student session into a scored attempt. Export CSV, drop into your LMS.

Topology audit — 04 / Audit

Caught before boot.

Static analysis runs on every save: duplicate IPs, subnet overlaps, mismatched interface speeds, isolated nodes.
