Abstract:

A throttle device is coupled with a central processing unit in a node for reducing traffic overload in a Next Generation Network (NGN). The device is coupled with a basic throttle with different levels of traffic priority and both are situated between a source node and a target node for processing traffic. When a traffic offer is received by the throttle, the throttle device by provisionally updating the basic throttle priority levels, determines whether to send the traffic offer on to the source node. If the provisional, traffic priority level is greater than a new traffic priority level the traffic is admitted and rejected if the updated priority level is less than the new traffic priority level.

BACKGROUND OF THE INVENTION

The present invention relates to telecom network media overload. More particularly, and not by way of limitation, the present invention is directed to a system and method for controlling signaling overload.

Prior Art and Problems

In Next Generation Networks (NGNs), many protocols, e.g., H.248.11 (also known as Gateway Control Protocol) are used for controlling media setup of a call. The protocol messages are processed on a central processing unit (CPU) of corresponding nodes.

Different types of nodes have different signal processing capacity and some nodes might have significantly higher capacity than others. Because of that there are scenarios, where signaling overload caused by the source node in a specified target node has a high probability of occurring.

Signaling overload causes system performance degradation even if the node is able to protect itself by rejecting offers. External overload control mechanisms have been developed ...
