Question: What does the Max-Supported-Bandwidth-UL AVP (AVP code 544) primarily indicate in the context of IP flows in a telecom network?
Option 1: The minimum required bandwidth for a downlink IP flow, excluding IP-layer overhead.
Option 2: The average supported bandwidth for both uplink and downlink IP flows, including all protocol overheads.
Option 3: The maximum supported bandwidth in bits per second for an uplink IP flow, including overhead from the IP layer and above (e.g., UDP, RTP, and RTP payload).
Option 4: The total available network bandwidth for all concurrent uplink and downlink IP flows.
Explanation: This is correct because the Max-Supported-Bandwidth-UL AVP specifically pertains to the maximum bandwidth supported for uplink IP flows, encompassing not just the payload but also the overhead from higher layers (IP, UDP, RTP, etc.). This detail is crucial for ensuring that the network can accommodate the total bandwidth requirements of uplink transmissions, preventing potential congestion or packet loss.
