Patent number: 9225657Abstract: The efficiency of real-time distribution of multimedia content over a heterogeneous network is optimized by locally, rather than centrally, adapting the content to conform to the capabilities limitations of the network. Multimedia content travels from a central location along the network backbone. When received by each of a system of dispersed media servers, that media server adapts the content by compensating for any QoS limitations of the downstream network segments. For example, the backbone of the communications network may consist of a satellite uplink. The dispersed media servers receive and replicate the content as required for distribution to unicast segments downstream rather than doing so at the source of the content, and thus multiple streams of identical content need not be carried on the backbone. Each dispersed server is programmed to optimize the transmission to conform to the transmission parameters of each adjacent and downstream segment of the network.Type: GrantFiled: March 19, 2013Date of Patent: December 29, 2015Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventor: Lee Friedman

Patent number: 8750141Abstract: Connection constraints are flooded using an extension to a routing protocol being used to control forwarding on network. Nodes maintain topology and connection database and calculate routes for connections based on the constraints. If a node is on a calculated route for a connection it will install forwarding state for the connection. Since each node has a consistent view of the network topology and has been provided with the constraints associated with the connection, each node on the network will calculate the same route for the connection. When a failure occurs, the nodes will calculate restoration paths for the connections on a network-wide priority basis to enable restoration paths to be created for the affected connections without requiring the restoration paths to be signaled. Time-stamps are used to allow events to be applied by nodes in a consistent order regardless of the order in which they arrive.Type: GrantFiled: November 5, 2009Date of Patent: June 10, 2014Assignee: Rockstar Consortium US LPInventors: Darek Skalecki, Peter Ashwood-Smith

Patent number: 8717890Abstract: A packet scheduling method and apparatus with the knowledge of application behavior, anticipated usage/behavior based on the type of content, and underlying transport conditions during the time of delivery, is disclosed. This type of scheduling is applicable to a content server or a transit network device in wireless (e.g., 3G, WIMAX, LTE, WIFI) or wire-line networks. Methods for identifying or estimating rendering times of multi-media objects, segmenting a large media content, and automatically pausing or delaying delivery are disclosed. The scheduling reduces transit network bandwidth wastage, and facilitates optimal sharing of network resources such as in a wireless network.Type: GrantFiled: January 29, 2010Date of Patent: May 6, 2014Assignee: Movik NetworksInventors: Surya Kumar Kovvali, Ramji Raghavan, Krishnan Ramakrishnan, Ronald Parker, Christopher Leary, Charles W.

Patent number: 8693335Abstract: Control packets received at a network element are pre-classified to enable out of profile traffic to be traced to an offending port. Pre-classified control packets are metered at a desired granularity using dynamically configured meters which adjust as ports are put into service or removed from service, and as services are applied to ports. CPU metering is implemented on a per-CPU core basis, but the per-CPU meters are used to perform flow control rather than as thresholds for ejecting errant control traffic. The combination of these three aspects provides robust CPU overload protection while allowing appropriate levels of control traffic to be provided to the control plane for processing, even in the event of a control traffic burst on one or more ports of the network element.Type: GrantFiled: March 22, 2012Date of Patent: April 8, 2014Assignee: Avaya Inc.Inventor: Hamid Assarpour

Patent number: 8687517Abstract: A method and device for identifying degradation in service quality for a wireless media service. The wireless media service has a known expected packet generation rate, which may be determined by the device based upon the codec and payload size selected on initiating the media service. At a receiving device, the packets actually received by the device from the other termination point are counted over a time period, and this number is compared with the number of packets that were expected based upon the known packet generation rate. From this comparison a packet loss rate may be determined. If the packet loss rate exceeds a threshold level, then the device may issue a user alert, terminate the service, or take other action. The threshold level may be established based upon a packet loss rate corresponding to a significant degree of service quality degradation.Type: GrantFiled: June 8, 2012Date of Patent: April 1, 2014Assignee: BlackBerry LimitedInventors: Sherif Abdel-Kader, Michael Chen

Patent number: 8681622Abstract: A system for congestion control in a mobile communications network includes a monitoring module configured to monitor message traffic associated with a cell in a mobile communications network. The message traffic includes control plane and user plane messages. The monitoring module determines, based on the message traffic, whether a predetermined congestion threshold associated with the cell in the mobile communications network has been crossed. In response to the threshold being crossed, the monitoring module generates a cell congestion notification message that includes the identity of subscribers that are contributing to the congestion. A policy server receives the cell congestion notification message and generates a PCC rule that modifies the policy of the one or more identified subscribers and for communicating the PCC rule to a PCEF.Type: GrantFiled: December 19, 2011Date of Patent: March 25, 2014Assignee: Tekelec, Inc.Inventors: Amit H.
