Publication number: 20170052959Abstract: A method of filtering and scoring a plurality of resources where each resource can be associated with a plurality of attribute values. For each resource at least a subset of the attribute values can be applied to an input layer of a multilevel classifier, such as a neural network. The multilevel classifier can be used to generate intra-level values for nodes in an intermediate layer of the multilevel classifier and output values for node at an output layer of the multilevel classifier. The output values and associated intra-level values can be used to determine a confidence indicator or qualification score for the resource. The confidence indicators or qualification scores for the resources can be compared to filter the resources.Type: ApplicationFiled: August 18, 2016Publication date: February 23, 2017Inventors: Jonathan Felske, Peter Myers, Eziah Syed, Delfin Montuno, Kent Felske

Patent number: 9064093Abstract: A system in which data signatures are used to identify copyrighted content passing through a network. The data signatures are derived from files containing copyrighted content to be identified. The signatures are used to search within peer-to-peer data streams flowing through one or more network nodes in a communications network. Any specific technique may be used for pattern recognition between the signatures and the monitored traffic. When a particular file of interest is identified, the system may operate to perform one or more of several possible actions, including stopping the transmission, allowing the transmission but recording the event, making an offer to the recipient allowing them to legally purchase the file, or sending alternative information or intentionally corrupting the information to render it useless to the recipient.Type: GrantFiled: December 22, 2003Date of Patent: June 23, 2015Assignee: Apple Inc.Inventors: Kent Felske, James Aweya, Delfin Montuno, Michel Ouellette

Publication number: 20150089057Abstract: Domains (multiple collaborating service providers) create service offerings between pairs of edge nodes that interconnect with other domains in the network. The service offerings may specify the available bandwidth, quality of service, reliability, available security, price, subscriber and service contextual specific and other SLA information. When a new service is to be created, the service definition is used along with information about the available service offerings to determine a set of networks to implement the service. Information associated with the service offerings may be flooded to all other networks. Alternatively, the service offering information may be provided to a trusted third party (SLA broker) which may provide SLA services on the network to select sets of domains to implement inter-domain services, and may also proxy to set up the service for the SLA requesting party. A hybrid approach may also be used.Type: ApplicationFiled: December 9, 2014Publication date: March 26, 2015Inventors: Ravishankar RAVINDRAN, Francois BLOUIN, Delfin MONTUNO

Publication number: 20140064273Abstract: A set of critical nodes or links is identified on the network through which most of the shortest paths on the network occur. Each node compares their distance to end points on the network with a distance between the end points and each of the distinct critical nodes. Where the distance between the end points and the critical nodes is shorter than the distance between the end points and the node, the node is not on the shortest path and does not install forwarding state. Where the distance between the end points and the critical node is larger than or equal to the distance between the end points and the node, the node may be on the shortest path between the pair of end nodes and installs forwarding state. Installation of forwarding state may cause packet duplication, but determining forwarding state is dramatically simplified.Type: ApplicationFiled: November 12, 2013Publication date: March 6, 2014Applicant: Rockstar Consortium US LPInventors: Abel Dasylva, Delfin Montuno, Peter Ashwood Smith, Francois Blouin, Tadeusz Drwiega

Patent number: 8230513Abstract: A traffic controller is provided which integrates black-box tests of unauthorized applications to extract application characteristics from associated Internet traffic, exploits the networking information learned by host clients, actively scans and controls hosts on the corporate network, and dynamically configures a corporate firewall to block traffic to and from critical application network elements. As a result, the traffic controller effectively manages unauthorized applications and their associated traffic in a corporate environment.Type: GrantFiled: June 27, 2011Date of Patent: July 24, 2012Assignee: Avaya Inc.Inventors: Wenfeng Chen, Michel Ouellette, Delfin Montuno, Kent Felske

Patent number: 7835366Abstract: The invention includes a technique for clock recovery in a network having master and slave clocks in respective Time Division Multiplexing (“TDM”) network segments which are interconnected by a non-TDM segment. Master clock timestamps are sent to the slave. The slave measures a master clock timestamp inter-arrival interval, and sends slave clock timestamps to the master. The master measures a slave clock timestamp inter-arrival interval, and sends that slave clock timestamp inter-arrival interval to the slave. The slave then calculates an error signal based at least in-part on the difference between the master clock timestamp inter-arrival interval and the slave clock timestamp inter-arrival interval, and employs the difference to recover the first service clock in the second TDM segment.Type: GrantFiled: February 27, 2006Date of Patent: November 16, 2010Assignee: Ciena CorporationInventors: James Aweya, Michel Ouellette, Delfin Montuno, Kent Felske

Patent number: 7684333Abstract: A method and system for allocating bandwidth of a wireless channel to different types of traffic includes partitioning the bandwidth of the wireless channel into a plurality of contention periods. Traffic flows are associated with access categories, and one or more of the access categories are assigned to each contention period. During at least one of the contention periods, traffic flows associated with a proper subset of the access categories contend for access to the wireless channel.Type: GrantFiled: July 28, 2005Date of Patent: March 23, 2010Assignee: AVAYA, Inc.Inventors: Abel Clement Dasylva, Zhonghui Yao, Delfin Montuno, Michel Ouellette, James Aweya, Wenfeng Chen, Kent Felske

Patent number: 7492732Abstract: Where a common network clock is available at both a TDM receiver and a TDM transmitter which communicate via a packet network, differential clock recovery can be accomplished by matching the number of service clock pulses in a network reference clock period at the transmitter and receiver. In one embodiment the transmitter need only send a counter value from a counter that is clocked and reset, respectively, by the service clock and network reference clock, thereby allowing use of different types of oscillators, both analog and digital, to be implemented at the transmitter and receiver. The technique is also general enough to be applied in a wide variety of packet networks including but not limited to IP, MPLS and Ethernet. In an alternative embodiment, a faster derived network clock fdnc drives both the transmitter and receiver counters, which in turn are reset, respectively by the slower transmitter service clock fsc and slower receiver service clock frc.Type: GrantFiled: December 5, 2005Date of Patent: February 17, 2009Assignee: Nortel Networks LimitedInventors: James Aweya, Michel Ouellette, Delfin Montuno, Kent Felske

Patent number: 7424546Abstract: Disclosed is an Active Queue Management method and apparatus which uses traffic rate information for congestion control. Using a nonlinear fluid-flow model of Traffic Control Protocol, a proportional-integral controller in a closed loop configuration with gain settings characterized for stable operation allows a matching of the aggregate rate of the active TCP connections to the available capacity. Further disclosed is a method for calculation of the regime of gain settings for which stable operation of a given network obtains. This approach allows for capacity matching while maintaining minimal queue size and high link utilization.Type: GrantFiled: April 30, 2003Date of Patent: September 9, 2008Assignee: Nortel Networks LimitedInventors: James Aweya, Michel Ouellette, Delfin Montuno, Kent Felske
