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.
