TSN / GCL ILP Solver
ROii Realistic Sensor Demo
Realistic sensor model: AutoL G32 (128KB point cloud), Hesai Pandar 40P (32KB sub-sampled), Continental MRR-35 (4KB ×2 at 50Hz). All 1 Gbps links. Standard (13 nodes) and Reconfigured (14 nodes + 802.1CB replicator) topologies.
ROii Streaming Sensor Demo
Real-time streaming model: sensors emit small UDP packets continuously instead of large bursts. G32 LiDAR streams 1200B every 100µs, Pandar 40P every 300µs, MRR-35 CAN2ETH every 1500µs. Cycle = 1.5ms, 45 pkts/cycle. Compare Burst vs Streaming modes.
ROii Real LiDAR Analysis
Real measured traffic from Ouster OS-1-16-A0: 416KB/frame at 10Hz, 128 UDP packets of 3,328B each, 3 IP fragments per packet. Deadline feasibility sweep, burst vs IP-fragmented comparison, spec vs real (G32 128KB vs Ouster 416KB — 3.25× larger).
ROii Balanced Grid Demo
IEEE 802.1CB frame replicator: a single REP device receives LIDAR_FC and RADAR_F frames and duplicates them to both SW_FL and SW_FR for balanced load distribution. 14 nodes, 18 links, 11 flows. Link failure scenarios with automatic rerouting.
ROii Optimal Tri-Star Topology
Optimized topology: each switch has a direct 1 Gbps link to ACU-IT. All flows are 2 hops (sensor → zone switch → ACU-IT). Max e2e delay drops ~50% vs Standard. Triangle backbone for failover only. 13 nodes, 18 links, 9 flows.
ROii 8-TC Dedicated PCP
All 8 traffic classes dedicated to sensor flows — no best-effort. Each LiDAR gets its own PCP (7–4), radars share remaining PCPs (3–0). Per-board GCL configuration table with 8-bit gate mask visualization and PCP→Queue mapping for LAN9692 switches.
ROii 8-TC v21 — Balanced Sensor
Complete overhaul: balanced 3-3-3 sensor wiring (3 sensors per zone switch), warm LiDAR / cool radar color scheme, new payloads (G32 1248B, Pandar 812B, MRR-35 128B), 500µs cycle with 1000µs deadline. Single model with Greedy vs ILP comparison. Diamond topology layout.
ROii 8-TC Stable (TX Margin)
Hardware-safe version of 8-TC with TX Margin (inter-packet gap). Enforces minimum 2µs spacing between packets to absorb PTP sync error, GCL transition jitter, and store-and-forward variation. Adjustable cycle, guard, processing delay, and margin parameters.
ROii Hardware-Accurate
Actual sensor H/W specs: LiDAR on Ethernet, Radar on CAN-FD, Camera on V-by-One@HS. 3-mode comparison: Direct (no switch), 1G Gateway (bottleneck ~31.7%), 10G-T1 Gateway (bottleneck 3.2%). Mixed-speed links — 10× bottleneck reduction.
ILP Learning Mode
Interactive learning tool: edit flow payloads, periods, deadlines, and global parameters in real-time. Visualizes ILP formulation with variable counts, constraint breakdown, Big-M examples, and per-packet scheduling detail. Greedy vs ILP comparison.
Scheduler Animation
Watch the greedy scheduler fill the timeline step by step. Web Audio API tones for each packet placement. Dark theme, topology highlighting, conflict detection, real-time stats. Switch between Standard, Reconf, and Optimal models.
Branch & Bound Solver
Custom B&B ILP solver with D3 tree visualization. Watch branching, bounding, and pruning in real-time. Web Audio tones for each solver event. Full model — no simplification.
Custom Playground
Interactive topology editor with collapsible sidebar. Add/remove nodes, links, flows in real-time. Greedy & ILP solvers with auto-solve, solution history, JSON export/import. Full 3D visualization and all GCL charts.
