AVoIP Bandwidth Calculator
Calculate network bandwidth for AVoIP systems. Add streams, configure settings, and see if your network can handle it.
More efficient than H.264. Lower bandwidth for same quality. Runs on 1GbE.
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 (Crestron, Extron, AMX), PTP/NTP sync, IGMP queries, and firmware updates.
4. Check your trunks — per-port bandwidth is only half the picture. Use the Trunk Analysis above to model your switch topology and find overloaded inter-switch links before they cause dropped frames.
5. Verify switch hardware — check backplane capacity (total throughput across all ports), per-port throughput (some switches share bandwidth between port groups), and that IGMP snooping is enabled with a querier configured.
6. Plan for growth — keep utilization below 70% to accommodate burst traffic and future expansion. A network at 95% will drop frames during peaks even if average bandwidth looks fine.
Bandwidth estimates use conservative compression ratios for worst-case planning. Actual throughput varies with content complexity.
