Question: What does the Extended-Max-Requested-BW-DL AVP (AVP code 554) specifically indicate for a downlink IP flow in terms of bandwidth measurement?
Option 1: The maximum requested bandwidth in kbit/s, inclusive of overhead from IP-layer and above (e.g., IP, UDP, RTP, and RTP payload).
Option 2: The minimum guaranteed bandwidth in kbit/s, exclusive of overhead from the transport layer.
Option 3: The average utilized bandwidth in kbit/s for uplink and downlink IP flows combined.
Option 4: The total available bandwidth in kbit/s for all concurrent downlink IP flows.
Explanation: This is correct because the Extended-Max-Requested-BW-DL AVP specifically measures the maximum requested bandwidth for a downlink IP flow, encompassing not just the payload but also overhead from layers above the IP layer, including UDP, RTP, and the RTP payload itself, providing a comprehensive measure of required bandwidth.
