Patent number: 9577842Abstract: Systems and/or methods that facilitate the segmentation of layer 3 (L3) data to more than one virtual private network (VPN) or virtual network (vNET) are presented. An application classifier component can be used to facilitate the classification of L2 to and from hosts and/or other networking components that are attached to a network based on the type of application with which the network traffic is associated. The innovation associates multiple Virtual Local Area Networks (VLANs) with the same L2 forwarding table ahead of bridging into shadow VLANs (SVLANs) which can be associated with different L3 vNETs. The application classifier component can classify data traffic at the switch port through Switching Virtual Interfaces (SVIs) into SVLANs which can be associated with different L3 vNETs. Each vNET can be optimized and provide services specific to which type of application in which the vNET is associated.Type: GrantFiled: February 25, 2008Date of Patent: February 21, 2017Assignee: Cisco Technology, Inc.Inventors: Suran Saminda De Silva, Chandrashekhar Appanna

Patent number: 9521593Abstract: Packet data protocol (PDP) contexts are managed upon cellular-to-femto handover, wherein femto network has disparate capabilities to support applications with distinct access point names (APNs) and quality of service (QoS) profiles. Based at least on activity factors of applications associated with PDP contexts, a QoS-based ranking of PDP contexts, and subscriber input, cellular network platform selects active PDP contexts to retain and suspend upon handover. A group of active PDP contexts is handed off in accordance with femto coverage capability, with remaining active PDP contexts suspended during handover. When a suspended PDP context, and application associated therewith, is resumed through femto coverage, a PDP context modification is conducted with a new APN and the application is routed to a corresponding femto gateway node and application server. Additionally, femto network platform performs a radio access bearer reconfiguration to meet QoS requirements of the resumed PDP context.Type: GrantFiled: September 17, 2015Date of Patent: December 13, 2016Assignee: AT&T MOBILITY II LLCInventor: Yung Shirley Choi-Grogan

Patent number: 9456056Abstract: Methods and systems for processing data requests in a client-server computing environment, such as the Web, are disclosed. A client device initially transmits a data request to a randomly selected first server device. The first server device may reject the data request if its request queue threshold is exceeded. The client device retransmits the data request, including the request queue threshold, to a randomly selected second server device. The second server device may reject the data request if the request queue threshold of the first server device is smaller than a request queue threshold of the second server device. The client device transmits the data request back to the first server device, including the request queue threshold of the second server device. The first server device processes the data request and adjusts its request queue threshold based on the request queue thresholds of the first and second server devices.Type: GrantFiled: November 4, 2013Date of Patent: September 27, 2016Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Vivek Rai, Dan Mihai Dumitriu, Swaminathan Sivasubramanian

Patent number: 9450686Abstract: An apparatus and method for testing an upstream path of a cable network are disclosed. The upstream path is tested by capturing and analyzing upstream data packets generated by a specific terminal device. A test instrument is connected at a node of the cable network. The test instrument establishes a communication session with the headend, informing the headend of an identifier of the device that will generate the test upstream data packet. The test upstream data packet is captured and analyzed at the headend, so that the results of the analysis can be communicated back to the test instrument. To speed up the packet capturing and filtering process, the upstream data packets can be pre-filtered based on packet duration and/or arrival time.Type: GrantFiled: June 30, 2011Date of Patent: September 20, 2016Assignee: VIAVI SOLUTIONS INC.Inventors: Michael D.

Patent number: 9432991Abstract: Providing for improved implementation of supplemental wireless nodes in a wireless base station deployment is described herein. By way of example, a donor base station is configured to send a schedule of data transmission to and from a set of UEs served by the base station, and further can provide the schedule and identifiers for the set of UEs to one or more wireless nodes serving the base station. Respective access channel measurements between respective UEs and respective wireless nodes can be forwarded to the base station, which in turn can identify optimal access channels for the set of UEs. Additionally, the donor base station can schedule multiple data transmissions on these access channels in a common transmission time slot, to achieve cell-splitting gains for the data transmissions.

Patent number: 9369586Abstract: A method for telephony includes receiving at an Internet telephony service provider a subscriber request to place a call to a telephone number. A cache associated with the internet telephony service provider is queried to check if the cache holds a record for the telephone number. If the cache holds the record, the record is obtained. If the cache does not hold the record, a request is sent to a database server that maintains a database of records associating endpoint user terminal telephone numbers of subscribers with respective packet network addresses of the endpoint user terminal. The call is placed to the endpoint user terminal telephone number via a public switched telephone network while the request is sent to the database server to retrieve the packet network address of the endpoint user terminal to which calls to the telephone number should be placed.Type: GrantFiled: August 11, 2014Date of Patent: June 14, 2016Assignee: XCONNECT GLOBAL NETWORKS LTDInventors: Baruch Sterman, David Schwartz, Eli Katz
