Abstract:
1. A method for reducing an overload condition at a node of a communication system, comprising the steps of: storing sets of overload range values in a memory, wherein each overload range that corresponds to a set of overload range values represents a range of used capacity of a component of the node; storing rejection proportion values in the memory, wherein each rejection proportion value is associated with an overload range and represents a proportion of messages received at the node to reject when the used capacity of a particular component of the node is within the overload range with which the rejection proportion value is associated; determining current used capacity of the particular component; and rejecting a quantity of messages received at the node equal to the rejection proportion value that is associated with an overload range in which the current used capacity of the particular component falls.
