How does a TSC facilitate network convergence?

A Tactical Session Controller (TSC) plays a critical role in network convergence by enabling various communication services—specifically voice, video, and data—to operate over a single, unified infrastructure. This integration is essential for modern networks as it streamlines operations, reduces costs associated with maintaining separate networks for each service, and enhances the user experience through better resource management.

By allowing different types of services to coexist on a common platform, a TSC can effectively manage the flow of traffic and prioritize it based on real-time needs, ensuring optimal performance for each type of service. This capability not only maximizes the utilization of the existing infrastructure but also simplifies network management by reducing complexity.

The other choices do not align with the principle of network convergence that a TSC provides. Limiting data to one type of service would hinder the very essence of convergence, while isolating services on separate networks goes against the goal of integrating them. Optimizing bandwidth for each type of service is a relevant function, but it is part of a broader framework which is inherently about enabling convergence rather than confining services separately.
