Question: What does the Extended-Min-Desired-BW-DL AVP (AVP code 558) specifically indicate for a downlink IP flow in a telecom network?
Option 1: The maximum tolerated jitter for real-time media transmission.
Option 2: The minimum required Quality of Service (QoS) class identifier.
Option 3: The minimum desired bandwidth in kbit/s, including overhead from IP-layer and above (e.g., IP, UDP, RTP, and RTP payload).
Option 4: The average packet loss rate for non-real-time data applications.
Explanation: This is correct because the Extended-Min-Desired-BW-DL AVP indicates the minimum desired bandwidth for a downlink IP flow, encompassing not just the payload but also overhead from various protocol layers (IP, UDP, RTP, etc.), crucial for ensuring sufficient network resources are allocated for smooth data transmission, key in managing resource allocation and Quality of Service (QoS) effectively.
