Patent number: 8023408Abstract: A message sequence regulator (MSR) system includes a message parser, a message extraction repository, a rules repository, a message definition repository, an interface to a resource monitor for monitoring system resources by single resource monitoring agents, and a notification component for identifying sequence regulation operations which cannot be executed. The MSR system receives copies of messages loaded into or retrieved from queues by a queue manager as well as event messages from the resource monitor. The message extracts parts of the message using message structures defined in the rules repository and stores the extracted parts in the message extraction repository. If a defined condition is found to exist, the MSR system initiates calculation of an appropriate message sequence number or message priority level. The queue manager updates the message record without removing the message from the queue.Type: GrantFiled: November 15, 2005Date of Patent: September 20, 2011Assignee: International Business Machines CorporationInventor: Christian Herrmann

Patent number: 7929532Abstract: A method and integrated hardware system for multicast transmission shaping in EPONs which employs a selective multicast algorithm that significantly reduces the complexity of traffic shaping for multicast traffic. Unlike prior art methods, my method exploits the broadcasting nature of the downstream point-to-multipoint access system including EPONs. Operationally, the method transforms a multicast traffic shaping problem into a unicast traffic shaping problem by selecting a multicast subscriber and subsequently treating packets addressed to that selected multicast subscriber as unicast. Advantageously, these packets are still available to other members of the multicast group. And since these packets are treated as unicast from the perspective of traffic shaping, my inventive method significantly reduces traffic shaping complexity in multicast environment.Type: GrantFiled: November 30, 2005Date of Patent: April 19, 2011Assignee: Cortina Systems, Inc.Inventor: Charles Chen

Patent number: 7889750Abstract: In a packet processing system, where a packet processor normally performs a fixed number of processing cycles on a packet as it progresses through a processing pipeline, a method of extending the fixed number of processing cycles for a particular packet is provided. During the processing of a packet, an extension bit associated with the packet is set to an “on” state if extended processing of the packet is needed. While the extension bit is set to that state, updating of a count, indicating the number of processing cycles that has been undertaken for the packet, is inhibited. When the extended processing of the packet has been completed, the extension bit for the packet is set to an “off” state, and the updating of the count resumed. When that count indicates the number of processing cycles the packet has undergone equals or exceeds the fixed number, the packet is exited from the pipeline.Type: GrantFiled: December 30, 2005Date of Patent: February 15, 2011Assignee: Extreme Networks, Inc.Inventor: David K. Parker

Patent number: 7885285Abstract: A probabilistic method of determining a second vehicle in the VANET to which a packet is to be forwarded from a first vehicle is provided. The method includes determining the second vehicle to forward the packet from the first vehicle based on pre-calculated expected latency data corresponding to the second vehicle, and forwarding the packet from the first vehicle to the determined second vehicle. The expected latency data is indicative of the latency expected for communication of the packet from the first vehicle to the destination if the packet is forwarded from the first vehicle to the second vehicle, and is calculated in advance of the step of the determining the second vehicle to forward the packet. The second vehicle to forward the packet may also be determined based on pre-calculated communication probability data corresponding to the second vehicle in addition to the pre-calculated expected latency.Type: GrantFiled: September 29, 2008Date of Patent: February 8, 2011Assignee: Toyota Infotechnology Center Co., Ltd.Inventor: Junichiro Fukuyama
