Filed:

Feb 11, 2003

Appl. No.:

10/361984

Inventors:

Diwakar Tundlam - Sunnyvale CA, US
Thirumalpathy Balakrishnan - Santa Clara CA, US

Assignee:

Alcatel-Lucent USA Inc. - Murray Hill NJ

International Classification:

G06F 15/173

US Classification:

709238, 709239, 709240, 709241, 709242, 709243, 709244

Abstract:

A method and system for distributing data packets within a network node is disclosed. The method and system for distributing data packets within a network node involves the utilization of a moving weighted average function to dynamically distribute the data packets in a balanced fashion. By utilizing a moving weighted average function to dynamically distribute the data packets in a balanced fashion, data packets are distributed more efficiently thereby increasing the overall efficiency of network operations. The method and system include computing a ratio matrix based on a moving weight average function of a load over a plurality of data ports and distributing data packets to the plurality of data ports based on the ratio matrix.

International Classification:

G01R031/08

US Classification:

370/232000

Abstract:

Rate-limiting a traffic stream using a rate-limit hierarchy involves subjecting a packet to a first rate-limit check, said first rate-limit check corresponding to a first-level traffic classification, subjecting said packet to a second rate-limit check and an infinity rate-limit check, said second rate-limit check and said infinity rate-limit check corresponding to a second-level traffic classification, granting an automatic pass to said packet from said infinity rate-limit check regardless of whether or not said packet passes said second rate-limit check, and granting an overall pass of said rate-limit hierarchy if said packet passes said first rate-limit check. In an embodiment, the first-level traffic classification is a parent classification of said second-level traffic classification and said second-level traffic classification is a child classification of said first-level traffic classification.

Abstract:

Systems and methods are disclosed for allocating and distributing power management budgets for subsystems (e.g., power usage clients) of a computer system. A power budget allocation subsystem may include a plurality of feedback branches having different associated time constants. Power usage clients with slower power response times may be provided power budgets based on a feedback branch having an associated longer time constant, while power usage clients with faster power response times may be provided with power budgets based on a feedback branch having an associated shorter time constant. The power budgets may be determined in the feedback branches based on power budgeting policies weighting the power budget of each subsystem relative to total power mitigation.
