Method of throttling data flow through a router
First Claim
Patent Images
1. A method of throttling data flow to a router, comprising:
- throttling data that will flow through a router based on a priority class of the data; and
updating the throttling parameter based on whether the data was throttled and a cost of router resources for processing a type of data,wherein the throttling step throttles the data based on a comparison of a throttling parameter to a throttling threshold associated with a priority class of the data, the throttling parameter representing a desired level of throttling for the router, and the throttling parameter being a deviation of actual throttling from desired throttling.

Abstract
In the method of throttling data flow through a router, a load parameter, which represents allowable load on the router, is determined and a state of overload control determined based on the load parameter. Overload control mechanisms associated with the determined state are then implemented. One of the overload control mechanisms throttles data that will flow through a router based on a priority class of the data.

7. A method of throttling data flow to a router, comprising:
-
determining a load parameter representing allowable load on the router based on an average occupancy of router resources, a target occupancy of router resources, and a previous load parameter; determining a state of overload control based on the load parameter; and implementing overload control mechanisms associated with the determined state, the overload control mechanisms including at least extending an interval at which messages are output to the router, the messages being one of messages supplying measurements used to determine whether a call should be handed off and registration messages. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
