Patent number: 8472313Abstract: Optical bypass circuits are selected and created with a desired amount of traffic on each circuit to offload from the IP routers, the maximum possible amount of traffic. In a first phase, each node in a network independently determines the maximum number of optical bypass circuits, configured to their maximum capacity, to as many destinations, that could possibly originate at that node. The determination is made by aggregating traffic from a given traffic matrix. The optical bypass circuit transports traffic that originates at the node plus transient traffic that the node receives from other nodes. In the second phase, the node will eliminate an optical bypass circuit found in the first phase if any of its parent nodes created a necessarily longer optical bypass circuit to the same destination. In addition, if a descendent node has more aggregate traffic to fill more bypass circuits than the parent node, then the extra optical bypass circuits from the descendent node are also created.Type: GrantFiled: May 26, 2010Date of Patent: June 25, 2013Assignee: Telcordia Technologies, Inc.Inventor: Mark Karol

Patent number: 8472467Abstract: Embodiments of a wireless device and method for channel access are generally described herein. In some embodiments, the wireless device is configured to measure channel quality and set a backoff delay for channel access based on the channel quality. Shorter backoff delays are set for better channel quality and longer backoff delays are set for poorer channel quality.Type: GrantFiled: June 25, 2009Date of Patent: June 25, 2013Assignee: Intel CorporationInventors: Ozgur Oyman, Qinghua Li, Xintian E Lin

Patent number: 8467321Abstract: A method and system and computer readable medium for a voice quality measuring device that provides real-time, near real-time or contemporaneous voice quality statistics about impairments external to the voice quality conference bridge system, i.e. from participant's calls coming from a communication network into a voice quality conference bridge system is disclosed. The reports generated by the voice quality statistics provided by the voice quality measuring device will enable carriers to identify voice quality impairments. Moreover, the reports will also enable the customers to see, by means of the voice quality statistics, on a call-by-call basis, whether any voice quality impairments are external to the conferencing bridge system.Type: GrantFiled: August 26, 2009Date of Patent: June 18, 2013Assignee: West CorporationInventors: Jason Howard Groenjes, Srinivas Maganti, Myron P Sojka, Mark Steven Jarzynka

Patent number: 8468200Abstract: According to various embodiments of the disclosed method and apparatus, a node on a network submits to a network controller a request for the admission of a parameterized Quality of Service flow with in a MoCA network. A network controller receives the submission requesting creation of or update to a parameterized quality of service to support a flow with retransmission; sends a message to a first plurality of nodes in the network to request information from the first plurality of nodes regarding whether the retransmission flow can be created or updated; receives responses from the first plurality of nodes, wherein each response comprises information regarding whether its respective node can support the retransmission flow; and determines whether the retransmission flow can be supported by the first plurality of network nodes.Type: GrantFiled: January 15, 2010Date of Patent: June 18, 2013Assignee: Entropic Communications, Inc.Inventor: Zong Liang Wu

Patent number: 8462634Abstract: Disclosed herein are systems, methods, and computer-readable storage media for managing a packet network to deal with a problem of dropped audio packets. A triggering event signal indicates that audio marked packet traffic in the packet network has exceeded a capacity limit. Upon receiving the triggering event signal, a transmitting device transmits audio packets marked as non-audio packets through the packet network. The transmitting device, for example, is a VoIP telephone. The triggering event signal, for example, is generated when the audio marked packet traffic exceeds a dropped packet threshold, or when monitoring of audio marked packet traffic indicates that audio marked packet traffic approaches a committed data rate (CDR) threshold.Type: GrantFiled: June 30, 2010Date of Patent: June 11, 2013Assignee: Avaya Inc.Inventor: Jean Meloche

Patent number: 8462644Abstract: Method, apparatus, and computer program product embodiments are disclosed to improve network performance for ad hoc network initiation. Example embodiments include a new operational sequence for wireless devices initiating the use of an ad hoc network. The example embodiments require appropriately enabled wireless devices to only respond to probe request frames from other similarly appropriately enabled wireless devices. In this manner, two devices may avoid the time consuming effort of combining two different ad hoc networks into a single ad hoc network so that the two devices can communicate.Type: GrantFiled: December 30, 2008Date of Patent: June 11, 2013Assignee: Nokia CorporationInventors: Jarkko Kneckt, Mika Kasslin, Janne Marin

Patent number: 8462797Abstract: A method and apparatus are provided for transmitting, over a wireless link, video that is coded in multiple layers such that higher priority for the use of the transmission resources may be given to the lower layers of the layered video stream. The level of priority is signified by the session identification parameters, i.e., by the source and destination ip addresses and port numbers. These parameters are assigned to the base layer and to the one or more additional layers, respectively, such that at least two of said layers are assigned different parameter sets. At least the base layer is then transmitted on the wireless link.Type: GrantFiled: June 3, 2010Date of Patent: June 11, 2013Assignee: Alcatel LucentInventors: Bruce R. Cilli, Charles Payette

Patent number: 8451781Abstract: A method for transmitting a random access preamble using a random access procedure in a mobile communication system. The random access preamble transmission method includes selecting, upon triggering of the random access procedure, one of random access preamble sets predefined between a User Equipment (UE) and an Evolved Node B (ENB) according to whether a radio channel condition is greater than a radio channel condition threshold and a size of a message that the UE will transmit after transmission of the random access preamble is greater than a minimum message size, randomly selecting a random access preamble from the selected random access preamble set, and transmitting the selected random access preamble to the ENB over a random access channel.Type: GrantFiled: October 25, 2007Date of Patent: May 28, 2013Assignee: Samsung Electronics Co., LtdInventors: Kyeong-In Jeong, Himke Van Der Velde, Gert Jan Van Lieshout, Yong-Jun Kwak, Soeng-Hun Kim

Patent number: RE44435Abstract: Packet communication method and system in which a packet destined for a terminal is provided service according to a service table indexed by packet classification and the terminal's power mode. The service table may specify for a connection a predetermined quality of service or discarding the packet. For a power mode having an alerting (i.e., paging) mechanism, the service may include alerting the terminal. The service table may also include a network edge point's own service requests and service requests from terminals, provisioning servers, and handoff sources. For a multicast or broadcast packet, as each terminal may be in a different power mode, the associated service in the service table may therefore be different for each terminal. In that case, the packet is provided with service so that any given terminal is provided with at least the quality of service specified in the service table. Thus, a multicast or broadcast packet is discarded when the service specified for all terminals is “discard.Type: GrantFiled: March 9, 2010Date of Patent: August 13, 2013Assignee: NTT DoCoMo Inc.Inventors: Moo Ryong Jeong, Toshiro Kawahara
