What are some protocols that a TSC may need to support for multimedia sessions?

The correct answer identifies RTP (Real-time Transport Protocol) and RTCP (RTP Control Protocol) as essential protocols for multimedia sessions. RTP is designed for delivering audio and video over IP networks, making it highly suitable for real-time communications, such as video conferencing and streaming media. It handles the data transmission while ensuring timely delivery and proper synchronization of multimedia streams.

RTCP complements RTP by providing control and monitoring capabilities. It enables the collection of metrics, such as packet counts, round-trip time, and jitter, which is critical for maintaining quality in multimedia transmissions. By using both RTP and RTCP, a Tactical Session Controller is equipped to manage and optimize the multimedia sessions effectively.

In contrast, the other options do not pertain to multimedia sessions in the same relevant way. SMTP (Simple Mail Transfer Protocol) and FTP (File Transfer Protocol) focus on email transmission and file transfers, respectively. HTTP (Hypertext Transfer Protocol) is primarily concerned with web traffic, while SNMP (Simple Network Management Protocol) deals with network management rather than real-time data. SSH (Secure Shell) and Telnet are protocols used for secure remote access and command-line interface communication, which do not facilitate real-time media interaction.
