Question: What does the Min-Requested-Bandwidth-DL AVP (AVP code 534) primarily indicate in the context of a downlink IP flow in telecom networks?
Option 1: The maximum allowable latency for real-time applications like RTP.
Option 2: The minimum required signal-to-noise ratio (SNR) for reliable transmission.
Option 3: The minimum requested bandwidth in bits per second, including all overhead from IP-layer and above.
Option 4: The guaranteed bitrate for uplink transmissions to ensure QoS for voice calls.
Explanation: This AVP specifically pertains to indicating the minimum bandwidth required for a downlink IP flow, encompassing all overhead from the IP layer upwards (e.g., TCP, UDP, HTTP, RTP, and its payload), crucial for ensuring Quality of Service (QoS) in telecom networks. The other options relate to different aspects of network performance (latency, signal quality, and uplink guaranteed bitrate, respectively).
