20080298372 | STRUCTURE AND METHOD FOR SCHEDULER PIPELINE DESIGN FOR HIERARCHICAL LINK SHARING - A pipeline configuration is described for use in network traffic management for the hardware scheduling of events arranged in a hierarchical linkage. The configuration reduces costs by minimizing the use of external SRAM memory devices. This results in some external memory devices being shared by different types of control blocks, such as flow queue control blocks, frame control blocks and hierarchy control blocks. Both SRAM and DRAM memory devices are used, depending on the content of the control block (Read-Modify-Write or ‘read’ only) at enqueue and dequeue, or Read-Modify-Write solely at dequeue. The scheduler utilizes time-based calendars and weighted fair queueing calendars in the egress calendar design. Control blocks that are accessed infrequently are stored in DRAM memory while those accessed frequently are stored in SRAM. | 12-04-2008 |
20090080461 | FRAME ALTERATION LOGIC FOR NETWORK PROCESSORS - Packet switching node in a communication system includes apparatus for receiving incoming information packets or frames which contain header portions with formatting control blocks. Information in the frame's header contains frame alteration commands for modifying the information in the frame. The modifications include adding new information, deleting information, and overlaying information. Decoders and control devices in an alteration engine interpret the commands and apply the modifications to the frame data. Common and standard data patterns are stored for insertion or overlaying to conserve data packet space. | 03-26-2009 |
20090097404 | Oversubscribing Bandwidth In A Communications Network - A system and computer readable medium for oversubscribing bandwidth in a communication network, is disclosed. The system and computer readable medium includes policing a first data flow and outputting a first output data flow from the first meter, in relation to a first Committed Information Rate (CIR) and a first Peak Information Rate (PIR); policing a second data flow and outputting a second output data flow from the second meter in relation to a second CIR and a second PIR; and policing an aggregated output data flow of the first output data flow and the second output data through a third meter of the oversubscription module, where the aggregated output data flow is policed in relation to a third CIR and a third PIR. | 04-16-2009 |
20090125535 | STRUCTURE FOR DELETING LEAVES IN TREE TABLE STRUCTURES - Techniques and articles of manufacture are provided comprising computer readable programs that, when executed on the computer, cause the computer to delete a leaf from a Patricia tree having a direct table and a plurality of PSCB's which decode portions of the pattern of a leaf in the tree without shutting down the functioning of the tree. A leaf having a pattern is identified as a leaf to be deleted. Using the pattern, the tree is walked to identify the location of the leaf to be deleted. The leaf to be deleted is identified and deleted, and any relevant PSCB modified, if necessary. The technique also is applicable to deleting a prefix of a prefix. | 05-14-2009 |

20130156036 | ANALYSIS OF NETWORK PACKETS USING A GENERATED HASH CODE - A technique for analyzing network packets includes receiving, by a network processor, a network packet having a packet header including address and control information. A set of bytes are extracted, using the network processor, from the packet header and a set of input bits for generating a hash code are derived, using the network processor, from the set of bytes. Finally, the hash code is generated using the input bits. | 06-20-2013 |

20110178648 | Aircraft Power Management System - A method and associated system for managing power within an aircraft electrical system, the aircraft comprising a generator driven by a gas turbine engine for the supply of electrical power to the system, wherein the generator and electrical system are connected to a common energy store. The method comprises determining predicted electrical energy demands of the system and predicted thrust demands for the gas turbine engine over at least a portion of a flight. A plurality of time periods within at least said portion of the flight are defined and a desired rate of charge of the energy store for each time period is determined based upon the predicted thrust and electrical energy demands over said time period. The rate of charge of the energy store is controlled during the flight in accordance with the determined desired rate of charge for each time period. The desired rate of charge of the energy store may represent an optimal energy efficiency charge profile based on a global assessment of the operational characteristics of the flight. | 07-21-2011 |
