Question: What is the primary goal of a source GTP-C entity when implementing overload control mechanisms?
Option 1: To minimize the number of messages processed by the overloaded GTP-C entity.
Option 2: To maintain consistent network throughput, measured in terms of the rate of total number of messages successfully processed.
Option 3: To prioritize certain types of messages over others during periods of overload.
Option 4: To completely block all incoming messages until the overload is resolved.
Explanation: The primary goal of a source GTP-C entity when implementing overload control mechanisms is to maintain consistent network throughput, measured in terms of the rate of total number of messages successfully processed. This ensures that good throughput of the network remains consistent, even when no overload control is applied, and prevents over-throttling of messages which can negatively affect end-user services.
