Question: What does the Extended-Min-Requested-BW-DL AVP (AVP code 560) specifically indicate for a downlink IP flow in terms of bandwidth measurement?
Option 1: The maximum achievable bandwidth excluding overhead from layers above the IP layer.
Option 2: The average bandwidth usage over a specified time interval, including only TCP and UDP overhead.
Option 3: The minimum requested bandwidth in kbit per second, encompassing all overhead from the IP layer and above (e.g., IP, TCP, UDP, HTTP, RTP, and RTP payload).
Option 4: The guaranteed minimum bandwidth for a single application, excluding any protocol overhead.
Explanation: This is correct because the Extended-Min-Requested-BW-DL AVP indicates the minimum requested bandwidth for a downlink IP flow, explicitly including all overhead from the IP layer and above, ensuring accurate bandwidth allocation.
