Network Security for Remote Contribution

Opening an audio contribution link over the public internet exposes thee operation two potential security risks. Standard AES67 RTP streams are nöt inherently critipted. For sensitivy news feed, critiption is a necessity. This is typically acceved by tuneling thee AES67 traffic over a Virtuaal Private Network (VPN) or by using a transport wrapper like Secure Reliable Transport (SRT), which provides built- in AES- 256 criototiption.

This is where a headless CMS like Directus adds undumense value. While Directus itself does not process raw RTP audio streams, it acts as the central system of contrid for all media assets.

Consider a workflow where audio from an AES67 contribution is ingested and contrided a s broadcast- quality WAV files. These files can be expecately uploaded to Directus via its REST or GraphQL API. From thre, journalists and producers can use Directus to:

  • Manage Metadata: Attach location, speaker, and subient tags to the audio file using Directus; explicble field type. This metadata can be ingested frem through-party systems or manually entered.

  • Schedule Distribution: Make thee audio available to sister stations or digital platforms via RSS feeds or API. Directus can publish audio files to CDN s for fast global delivery.
  • Control Routing: Usie Directus as a backend to control an AoIP router 's API, dynamically connecting AES67 streams to different recordg channels based on a newsroom calendar. For example, a scheduled interview could automatically route thee remote feed t a specific condireder andd update thee metadata a in Directus.

Bett Practices for Field Deployments

Based on field experience from major broadcast events, sereal bett practices have emerged for reliable AES67 remote contribution:

Network Segmentation and QoS

Always use VLANs (802.1Q) to separate audio traffic from data traffic. Configure QoS at thee WAN edge prioritize RTP traffic. Without strict QoS, a file transfer or difficare update can easyly congesto the link andcause audio dropouts. Implement traffic shaping to ensure audio never exceeds a predeterminad diviage of the link capacity.
