HOLOPLOT Control offers configuration capabilities similar to those in Dante Controller when using Ravenna. This page will explain these capabilities and what you can do with them.
To configure the network settings, on the navigation bar, click Settings › Network Settings
To customize the system according to your network topology, you can create different network settings groups. Each group has unique PTP and audio VLAN settings, and you can assign Audio Modules to different network segments with multiple VLAN assignments, PTP clock domains, or roles.
While all Audio Modules are initially assigned to the "Default" Network Group during system setup, you can create additional groups if needed. This flexibility allows you to tailor the system to your specific network requirements.
Currently, only the X1 Audio Modules are supported. This setting allows you to define separate VLANs for primary and secondary networks for audio ingress.
Ravenna employs the PTPv2 standard as its clocking mechanism, which is sufficiently flexible to ensure compatibility with other standards such as ST2110 or AES67. To find an appropriate configuration, it is recommended to match your existing Ravenna/AES67 audio source.
Here are some guidance to get you started:
QOS PTP DSCP: The acronym QOS PTP DSCP stands for Quality-of-Service (QOS) Precision Time Protocol (PTP) Differentiated Services Code Point (DSCP). This term refers to the prioritization of network packages for supported switches, based on the QOS requirements of the application. More information is available on Ravenna's website.
for AES67/Dante inter compatibility: 46 (EF)
for Ravenna: 48 (CS6)
PTP Domain: When working in complex audio networks or sharing the same network with multiple AoIP standards, the domain for Audio Modules to handle PTP syncing can be defined.
Follower-Only mode: This option prevents Audio Modules from assuming the roles of Leader or Grand Leader in the network.
PTP priority 1 and 2: When Follower-only Mode is disabled, Audio Modules will advertise those priorities to participate in the BMCA (Best Master Clock Algorithm).
The value ranges from 0-255. A lower value is preferred for electing a Grand Leader.
PTP announce and sync interval: Allows for configuring different message intervals for PTP syncing and announcement.
PTP delay mechanism: Should be left in E2E unless specified otherwise.
Dante devices rely on the older PTPv1 standard and can only function in PTP Domain 0. If you're sharing a network with other Dante devices that aren't using AES67 mode, it's recommended that you use a different PTP Domain to avoid conflicts. It's crucial that your source device follows the same PTP Domain as well to ensure reliable synchronization.
In other systems, the terms follower-only, leader, and grand leader are sometimes replaced by slave-only, master, and grandmaster, respectively.
