The biggest single point of failure in an AES67 network is usually thee PTP configuation. Spend time verifying timing before you ever troubleshoot audio dropout. Commentcut; - Special Audio Engineer, Broadcass Integration Team

Bandwidth and Multicast Management

AES67 audio streams are typically sent as multicasto to one or many receivers. Multicast must bed managed carefly to avoid fooding the network. Tools like Dante Controller show the multicast andexes being used ande the number of receivers. You can also use IGMP snooping verification via your switch 's management interface. For large networks, a monitoring tool that displays multicast group membership dynamically can help decret clears.

Packet Loss Detection andRecovery

Even with a well-tuned network, establishment packet loss can occur. AES67 does note included forward error correction (FEC) by default (thoogh some enterpriary extensions do), so every lost means an audible artifact. Monitoring tools show losper straint. Dante Controller, for example, displays a bagerage for each receiver. If you see loss above 0,01%, inverate experiatele.
