Question: What is excluded from the value of the Desired-Max-Latency AVP (AVP code 567) in milliseconds?
Option 1: Only receiver's application-level processing (e.g., decoding)
Option 2: Application-level processing in both sender and receiver (e.g., retransmission, encoding/decoding)
Option 3: Network congestion and packet loss
Option 4: Transport layer protocol overhead
Explanation: The Desired-Max-Latency AVP measures end-to-end transport level packet latency, focusing on the network's contribution to delay. It excludes additional delays introduced by application-level activities in both sending and receiving ends, such as retransmissions or encoding/decoding processes, to provide a pure measure of transport-level efficiency.
