What does RSVP provide?

• A. Quality of Service for voice only
• B. Bandwidth reservation
• C. Signal routing
• D. Call control

Answer: (B)

RSVP is used to reserve network resources to meet QoS requirements for a data flow. It acts as a signaling mechanism that requests bandwidth along the path from sender to receiver, allowing routers to allocate the necessary capacity for that flow. This bandwidth reservation is the core function that distinguishes RSVP from general routing or call-control tasks. It can support various traffic types, not just voice, and it doesn’t perform signal routing or call control by itself.
