The following updates will be included in the ZEN Master April 1, 2024 release.


Features



The following new features were implemented in this release:


### New details UI for Sources&#xA;

• ZEN Master Source details screens are now updated to align with Broadcaster screens
UI, this includes:
o Persistent vital statistics information in the top panel.
o Configurable widget's view.
o VLC and WebRTC playback from the top panel.

### Thumbnails on Targets&#xA;

• Where applicable, Target details pages now include thumbnails.


### Auto-login into Broadcasters, ZECs, Feeders, and Receivers&#xA;

• When accessing the GUI of Broadcasters and ZEC’s via ZEN Master, the system now logs
Users in directly without the need to copy and paste in credentials.

### SCTE35 logs can be colored by type&#xA;

• SCTE-35 logs can now be optionally color-coded by using the show/hide colors toggle to
help with rapid identification and confirmation.


### Added the option to export SCTE35 UI logs&#xA;

• Data can be downloaded as an xml report.

### Priority client support for Zixi Push Other Sources&#xA;

• ZEN Master now supports the Broadcaster Priority Dource functionality for the ZIxi-
Push-Other Source Type.


### Azure Public IP Prefixes support&#xA;

• Unlike AWS, there is no IP pool feature in Azure.
• Azure Admins will need to create a Public IP Prefixes pool and create public IPs.
• The ID/Name of the Public IP pool can be provided in the cluster settings.
• ZEN Master will then create IPs on demand from the pool.

### Redirection Routing rules for Pull requests:&#xA;

• ZEN Master now provides the ability to set specific routing rules for Pull requests from
clusters or CIDR IP Ranges.
• The rules can be accessed and created via “+Add Rule” button on the new “Redirection
Rules” tab of the cluster page:
• Rules can be applied to the client end-point Cluster, or IP CIDR Range, from where the
pull request is initiated:
o When using ‘Cluster’ the rule applies to auto-pull requests only.
o CIDR rules apply to any Zixi pull request, including those from ZECs, IRDs etc.
• Rules are evaluated in order from lowest order to highest.
• The first matching rule will apply.
• Latency is determined by the following order: Redirection rule latency -> source auto-
pull/pull target latency -> default 1000ms

• Additional Notes:
o If there is no match, the default rule Prefer public IP with DTLS will be used.
o Private/NIC CIDR do not support DTLS and will redirect to a non-DTLS port.
o A configuration conflict is possible, such as a cluster enabled for DTLS only,
where a private/NIC redirection will never successfully connect.
o It is possible to use this as feature as an allow list by creating a 0.0.0.0/0 block
rule and give it the highest order. In this case, any connection not matched by a
rule with a lower order will finally be matched by the blocking rule.
