Publication number: 20190379589Abstract: Systems and methods for detecting patterns in data from a time-series are provided. In one implementation, a method for pattern detection includes obtaining data in a time-series and creating one-dimensional or multi-dimensional windows from the time-series data. The one-dimensional or multi-dimensional windows are created either independently or jointly with the time-series. The method also includes training a deep neural network with the one-dimensional or multi-dimensional windows utilizing historical and/or simulated data to provide a neural network model. Also, the method includes processing ongoing data with the neural network model to detect one or more patterns of a particular category in the ongoing data, and localizing the one or more patterns in time.Type: ApplicationFiled: June 4, 2019Publication date: December 12, 2019Inventors: Sid Ryan, Petar Djukic, Todd Morris, Stephen Shew

Patent number: 9106446Abstract: A method and apparatus for controlling bandwidth in a Virtual Private Network assigns and allocates transmission bandwidth to packet VPNs for either connectionless or connection-oriented communication. The method creates two views of transmission facilities: a user plane view and a control plane view. In the user plane view, the bandwidth of the transmission facility is split into quantified and identified partitions. In the control plane view, transmission facilities are represented as logical links forming a topology that can be used for the purpose of routing the VPN. The two views are tied together by assigning user plane partitions to VPN control plane links. As a result, the allocation of bandwidth to VPNs becomes a controllable and viewable entity, thereby facilitating management and QoS provisioning in a VPN network.Type: GrantFiled: June 11, 2012Date of Patent: August 11, 2015Assignee: RPX Clearinghouse, LLCInventors: Raymond Aubin, Malcolm Betts, Stephen Shew

Publication number: 20140040481Abstract: Network resources are assigned as dedicated, shared, or public network resources. The resources are then allocated to L1-VPN subscribers on demand. Splitting assignment of the resources from allocation of the resources enables resources to be assigned to more than one subscriber on the network. Temporary physical dedication of the resources to one of the subscribers may be accomplished by allocating the assigned resources on demand, so that particular subscribers are provided with dedicated resources on an as-needed basis. Dedication of the network resources allows the network resources to be configured, managed, and controlled by the customers. The network resources may be optical resources and the links may be time slots on particular fibers. Optionally, by enabling prioritization to cause displacement of link allocations, additional flexibility may be obtained in allocating links to L1-VPNs such as by allowing the use of private and shared resources by other subscribers.Type: ApplicationFiled: October 14, 2013Publication date: February 6, 2014Applicant: Rockstar Consortium US LPInventors: Raymond Aubin, Malcolm Betts, Stephen Shew

Patent number: 8300625Abstract: An aspect of the present invention provides a method of controlling a multi-layer transport network. In accordance with the invention a determination is made as to whether a connection supporting a performance requirement of a call can be established within a first layer of the network. If the connection cannot be established, an association is defined between the call and a second call instantiated within a respective server layer of the network. By this means a network call controller in a client layer relies on a call and connection in a server layer instead of a connection in the client layer.Type: GrantFiled: October 27, 2008Date of Patent: October 30, 2012Assignee: Ciena CorporationInventors: Stephen Shew, Malcolm Betts, Nigel Davis, Erning Ye

Patent number: 8125925Abstract: A method and system for changing the extent of data plane resources controlled by a control plane for a network connection which spans a contiguous set of nodes controlled by existing network control resources is disclosed. This is done in a non-disruptive manner. This typically involves two steps: i) Creating a new set of control plane resources for said network connection such that said data plane resources are shared with said existing network control resources; and ii) then terminating the existing network control resources such that said data plane resources are fully transferred to the new set of control plane resources without disrupting said network connection. The existing network control resources can be either a control plane resource or a non control plane resource. An example of a non control plane resource is network management software (e.g., an OSS (Operation Support System)), which forms part of the Management Plane.Type: GrantFiled: April 7, 2006Date of Patent: February 28, 2012Assignee: Ciena CorporationInventors: Darek Skalecki, Stephen Shew, Jean-Pierre Coupal

Patent number: 7782879Abstract: An aspect of the present invention provides a method of establishing call controller communication in a multi-layer transport network where a plurality of signaling communications networks may exist within each layer. An interlayer call controller association is enhanced to provide associations of multiple client call controllers to a single server layer call controller. A method of collecting sets of associations related to a single server layer call is provided so that a sequence of client call controllers may be constituted. The plurality of signaling communications networks is then used to pass control information between call controllers in that sequence.Type: GrantFiled: June 30, 2006Date of Patent: August 24, 2010Assignee: Ciena CorporationInventors: Evelyne Roch, Stephen Shew
