How does session description protocol (SDP) function in relation to TSCs?

Session Description Protocol (SDP) plays a crucial role in communication sessions by providing a format for describing multimedia sessions in a way that participants can understand. SDP details essential components such as the session name, the type of media, the transport protocol to be used (like RTP), and other configuration parameters needed to establish a successful communication session.

In the context of Tactical Session Controllers (TSCs), SDP is instrumental because it allows TSCs to facilitate and negotiate multimedia sessions between various endpoints. This process includes ensuring that both sides of the communication agree on necessary details, such as codecs and media types, before the communication is initiated. This capability is vital for sessions involving video conferencing, voice calls, or any interactive media where coordination of media parameters is required to ensure a seamless user experience. By ensuring that all relevant session details are communicated effectively, SDP empowers TSCs to manage and optimize live communication sessions efficiently.
