Question: What does the Extended-GBR-UL AVP (AVP code 2851) specifically guarantee for an uplink service data flow in a telecom network?
Option 1: A minimum latency threshold for packet transmission
Option 2: A guaranteed bitrate in kbit per second, inclusive of IP-layer and above overheads
Option 3: A maximum allowable packet loss rate for the flow
Option 4: An allocated buffer size for jitter compensation
Explanation: The Extended-GBR-UL AVP guarantees a bitrate in kbit per second for an uplink service data flow, including all overheads from the IP layer upwards, ensuring a certain throughput level and aiding in managing Quality of Service (QoS) expectations.
