Network Bandwidth

Bandwidth consumed by each audio stream (stereo)

50 UDP packets per second averaging 201  bytes each     (includes the IP header but not physical layer header)Therefore,  UDP (+ IP header) bandwidth is:       10050 bytes/sec (average) for each audio stream (~80Kbps)Discovery and keep-alive control traffic is negligible compared to this

Bandwidth consumed by each audio stream (mono)

50 UDP packets per second averaging 121  bytes each     (includes the IP header but not physical layer header)Therefore,  UDP (+ IP header) bandwidth is:       6050 bytes/sec (average) for each audio stream  (~48Kbps)Discovery and keep-alive control traffic is negligible
