What aspect of networking does a TSC manage in real-time communications?

The correct answer relates to the core responsibilities of a Tactical Session Controller (TSC) in managing real-time communications, which include session initiation, modification, and termination.

In real-time communications, sessions represent the ongoing exchange of data between participants, such as voice or video calls. The TSC plays a critical role in establishing these sessions by determining the necessary parameters, such as codec negotiation and media routing, at the initiation stage. Once a session is active, modifications might be necessary to adapt to changing network conditions or user needs, such as adding more participants or changing bandwidth allocation. Finally, when the communication concludes, the TSC also oversees the orderly termination of the session, ensuring that resources are properly released and that no residual connections are left open.

This comprehensive management of the session lifecycle is essential for maintaining high-quality and reliable real-time communications. The other options do not encapsulate the full range of functionalities that a TSC is designed to handle; they either focus on a limited part of the session lifecycle or pertain to areas outside the context of communication sessions.
