Design Guide

1. Map your signal flow - identify every video and audio stream. Each encoder-to-decoder path is a stream. Include presentation sources, cameras, signage, and DSP sends/returns.

2. Choose protocols - match to your hardware. Uncompressed (SDVoE, ST 2110) needs 10G+. Light compression (NVX, NDI) works on 1G. Heavy compression trades latency for lower bandwidth.

3. Account for overhead - reserve 10-20% for control systems, PTP/NTP sync, IGMP queries, and firmware updates.

4. Check your trunks - per-port bandwidth is only half the picture. Use Trunk Analysis to model switch topology and overloaded uplinks.

5. Verify switch hardware - check backplane capacity, per-port throughput, and IGMP snooping with a querier configured.

6. Plan for growth - keep utilization below 70% to allow burst traffic and future expansion.

Bandwidth estimates use conservative compression ratios for worst-case planning. Actual throughput varies with content complexity.
