Question: What is the primary purpose of Node Level Overload Control in GTP-C entities?
Option 1: To prevent severe overload and potential breakdown of the GTP-C node by advertising overload information at node level granularity.
Option 2: To prioritize high-priority traffic over low-priority traffic during congestion.
Option 3: To reduce the offered load on neighboring nodes in case of an overload situation.
Option 4: To dynamically adjust the nominal capacity of a GTP-C entity based on incoming signaling traffic.
Explanation: Node Level Overload Control is designed to prevent severe overload and potential breakdown of the GTP-C node by advertising overload information at node level granularity. This allows for mitigation policies to be applied towards the target node, ensuring that the offered incoming signaling traffic does not exceed its nominal capacity.
