Patent number: 9210616Abstract: A packet data system such as a TCP/IP network transmits packets containing a variety of data types along links in the network. Packets are transmitted in a stream between nodes interconnected by the links connections which conform to a transport layer protocol such as TCP, UDP, and RSTP, and includes wireless links, which transmit packets using a radio frequency (RF) medium. Typical protocols, however, are usually developed to optimize throughput and minimize data error and loss over wired links, and do not lend themselves well to a wireless link. By examining the data in a packet, performance characteristics such as a port number are determined. The performance characteristics indicate the application type, and therefore, the data type, of the packets carried on the connection.Type: GrantFiled: May 16, 2011Date of Patent: December 8, 2015Assignee: IPR Licensing, Inc.Inventors: Kevin L. Farley, James A. Proctor, Jr.

Patent number: 9210723Abstract: The invention relates to a transmission control method implemented by a station having at least one data frame to be transmitted via a wireless telecommunication network. In one aspect, the method comprises, at each selection round from a maximum number of selection rounds: a step of obtaining a value representative of either an authorization to transmit the frame, or of a prohibition to transmit the frame; and, when the value is representative of an authorization for transmission, transmitting an information signal in the network so as to indicate, to the other stations, that the station has obtained a value representative of an authorization for transmission. The transmission of the information signal is at least partially carried out during the transmission of a data frame in the network.Type: GrantFiled: June 27, 2011Date of Patent: December 8, 2015Assignee: OrangeInventors: Patrick Brown, Jérôme Galtier

Patent number: 9137089Abstract: A method of assembling a plurality of frames including cell/packet-formatted data according to a predetermined frame format for transmission in a communication signal in a wireless or satellite environment. The method begins by assembling a data payload for each frame having a first variable size, including at least one of a partial data cell/packet and a complete data cell/packet. Then, for each frame a block code having a second variable size is generated for use in error correction. Each frame is provided with a frame header which defines aspects of the frame. Finally, the data payload, the block code and the format header are combined to form a frame corresponding to the plurality of frames, the format header defining a first portion of the frame, the data payload defining a second portion of the frame and the block code defining a third portion of the frame.Type: GrantFiled: November 21, 2012Date of Patent: September 15, 2015Assignee: ViaSat, Inc.Inventor: Anil K.

Patent number: 9137161Abstract: A method implemented in a network for placing services at network devices is disclosed. The network contains a plurality of network devices and offers a set of services to subscribers. Subsets of the set of services are included in ordered service chains for subscribers. The method starts with determining a list of bandwidth consumption entities of a service for each service within the set of services, where each bandwidth consumption entity is based on one or more chains of services. Then a weight of each service is calculated based on the list of bandwidth consumption entities of the service and a service with a highest weight within the group of one or more services that have not been placed is selected. The selected service is then placed at a network device based at least partially on calculating bandwidth impacts to the network by the service.Type: GrantFiled: May 29, 2013Date of Patent: September 15, 2015Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventors: Ying Zhang, Neda Beheshti-Zavareh
