AES67 uses IEEE 1588-2008 Precision Time Protocol (PTPv2) for clock synchronisation. For standard networking equipment, AES67 defines configuration parameters for a "PTP profile for media applications", based on IEEE 1588 delay request-response sync and (optionally) peer-to-peer sync (IEEE 1588 Annexes J.3 and J4); event messages are ...

Three profiles for Precision Time Protocol (PTP) might potentially be used in the professional media environment: the Peer-to-Peer Default PTP Profile of IEEE Std 1588-2008, the Media Profile of AES67 and the SMPTE Profile of SMPTE ST 2059-2.

2022年4月2日 · 在AES67中，通过PTP（IEEE 1588-2008）实现时钟频率和相位的同步。 我们将应用了PTP协议的网络称为PTP域。 PTP域内有且只有一个同步时钟，域内的所有设备都与该时钟保持同步。

2022年11月30日 · The AES67 PTP media profile is based on the AES67 standard that is used for high-performance streaming and audio-over-IP interoperability in audio devices. AES67 uses IEEE 1588-2008 PTP for clock synchronization of devices and …

AES67 specifies that devices shall support IEEE 1588-2008 Default Profiles and should use AES67 Media Profile “PTP profile for media applications” in certain circumstances.

2022年8月11日 · AES67的PTP主时钟是竞选方式，在没有DDM做打开详细设置的时候，我们可以抓取PTP时钟信息来看看Dante板卡的运行参数。 可以查看这时候PTP V2的参数

AES67 is a standard for high-performance audio-over-IP interoperability. By implementing the standards definitions and requirements, devices otherwise adhering to specific AoIP protocols that don’t interoperate with each other (i.e. Dante, Livewire, QLAN or RAVENNA) can establish direct connectivity and become interoperable.

AES67 为音频IP系统提供了一个强大且可靠的框架，专注于互操作性、质量和灵活性。 通过标准化设备控制、连接管理、传输和时钟同步，AES67 使不同的音频IP系统能够无缝协同工作，无论使用何种制造商或专有协议。

2016年5月2日 · AES and SMPTE have both specified profiles for IEEE 1588-2008 Precision Time Protocol (PTP) for use in professional media applications; the respective standards being AES67 and SMPTE ST 2059-2.

In general, PTP-aware switches can usually only support one version of the PTP protocol – AES67 mandates the use of PTPv2. Since some solutions use PTPv1 for their legacy equipment (i.e. Dante), a PTP-aware switch may not properly forward those packets, effectively resulting in synchronisation problems in certain areas of the network.
