Question: What does the Max-Requested-Bandwidth-UL AVP (AVP code 516) indicate in an AA-Request message, in terms of bandwidth for an uplink IP flow?
Option 1: The minimum guaranteed bandwidth for an uplink IP flow, excluding IP-layer overhead.
Option 2: The maximum requested bandwidth for an uplink IP flow, including all overhead from the IP-layer and above (e.g., IP, UDP, RTP, and RTP payload).
Option 3: The average expected bandwidth usage for an uplink IP flow, considering only RTP payload.
Option 4: The total available network bandwidth for all uplink IP flows at a given time.
Explanation: This is correct because the Max-Requested-Bandwidth-UL AVP specifically indicates the maximum requested bandwidth for an uplink IP flow, encompassing all overhead from the IP layer upwards (including IP, UDP, RTP, and RTP payload) when sent in an AA-Request.
