Patent number: 10616271Abstract: A method and associated system for mitigating a Distributed Denial of Service (DDoS) attack on a target device including, receiving a plurality of data packets at a mitigation device, counting a number of occurrences of each destination address signature within each of a plurality of consecutive data packet windows, classifying each data packet window of the plurality of consecutive data packet windows as a potential attack window if the number of occurrences of any one destination address signature within the data packet window exceeds a destination address signature threshold value. The method further includes, determining a total number of potential attack windows within a sliding time window and limiting the transmission of the plurality of data packets from the mitigation device if a total number of potential attack windows within the sliding time window exceeds a potential attack window threshold value.Type: GrantFiled: December 12, 2017Date of Patent: April 7, 2020Assignee: MICROSEMI FREQUENCY AND TIME CORPORATIONInventors: Anne Gerardine O'Connell, Yves Cognet

Patent number: 10284930Abstract: Various electronic devices may benefit from appropriate power conservation techniques and tools. For example, low power techniques may benefit small form-factor pluggable applications. An apparatus can include a packet parsing functionality that includes a first order shallow packet parser configured to operate at line rate and a second order deep packet parser configured to operate only on received filtered packets and received packets destined for a management and/or central processing port. The apparatus can also include a microprocessor configured to manage the apparatus and configured to operate at a low duty cycle. The apparatus can further include a packet generator configured to be active only when generating certain packets of interest. The packet parsing function, the microprocessor, and the packet generator can be configured to provide data from a host port of a small form-factor pluggable device toward an optical port of the small form-factor pluggable device.Type: GrantFiled: September 28, 2017Date of Patent: May 7, 2019Assignee: Microsemi Frequency and Time CorporationInventors: Con Cremin, Yves Cognet, Anne O'Connell

Patent number: 8826296Abstract: A method is provided for supervising a plurality of units in a communications network. The method includes a step of a first supervisor device receiving from a plurality of units information notifications having a plurality of information fields. For each information notification received, at least one imprint is generated, which includes codes extracted from predetermined fields of the notification. The method further includes counting the number of occurrences of at least one imprint, and notifying at least one master supervisor device of at least one imprint and the number of occurrences counted for that imprint.Type: GrantFiled: October 23, 2007Date of Patent: September 2, 2014Assignee: France TelecomInventors: Emile Stephan, Yves Cognet

Publication number: 20100110199Abstract: The quality of video that is broadcast as a packet-based video stream is measured using decoded pictures in combination with information extracted from the transport stream and elementary stream layers of the packet-based video stream. The decoded pictures include selected frames and/or slices decoded from the packet-based video stream and are used to generate video content metrics. A composite score for the video quality can be generated from the video content metrics in combination with quality metrics of the transport stream and/or the elementary stream. If the composite score falls below a minimum score, a snapshot of the video is captured for later analysis.Type: ApplicationFiled: November 3, 2008Publication date: May 6, 2010Inventors: Stefan Winkler, Praveen Mohandas, Yves Cognet

Patent number: 7080160Abstract: A method for creating time-stamped frames sent between computers includes receiving and generating a universal coordinated time reference signal using a global positioning system. Clocks independent of operating systems of the sending and receiving computer are synchronized with the reference signal. A test frame is created including a tag having reserved fields for transmit and receive time stamps. The transmit time stamp is inserted into the reserved transmit time stamp field, without intervention of the sending computers central processing unit, that corresponds to the time on the synchronized clock at the instant the test frame is sent. The test frame having the transmit time stamp is received by the receiving computer, and a receive time stamp is inserted into the reserved receive time stamp field corresponding to the time on the synchronized clock of the receiving computer when the test frame was received.Type: GrantFiled: November 28, 2001Date of Patent: July 18, 2006Assignee: Qosmetrics, Inc.Inventors: Yves Cognet, Joseph Ovanesian, Armen Aynillan

Patent number: 6801505Abstract: The invention relates to a method of using computer equipment to send a time-stamped frame. The method implements: generating at a given instant TS a frame whose time stamp TO is equal to TS+&dgr;, where &dgr; is a time interval required by the computer equipment between generating a time-stamped frame and sending the last bit thereof; sending said time-stamped frame as generated at the instant TS when an absolute time clock of the computer equipment reaches a value equal to TS+&dgr;−&sgr; where &sgr; is the duration required for sending the bits of said frame, such that the last bit of the frame is sent at instant TS+&dgr;.Type: GrantFiled: November 28, 2000Date of Patent: October 5, 2004Assignee: QoSmetrics, Inc.Inventor: Yves Cognet
