Enabling SAP advertisement messages in xNodes

Updated by Bryan Jones


This document covers the steps required to enable the SAP advertisement feature on Telos Alliance xNodes.

This includes;

  • Analog xNode
  • AES3 xNode
  • Mixed Signal xNode
  • Microphone xNode
The GPIO xNode does not offer any audio and does not participate in SAP advertisements.


Full AES67 compliance requires that a receiver is able to receive an AES67 multicast stream without the need for any advertisement or configuration files. However, some receivers may require the use of other mechanisms, for example; SDP (Session Description Protocol) files or SAP (Session Advertisement Protocol) messages. These receivers are referred to as compatible.
