摘要:
A system and method for dynamic traffic load balancing with a multiple physical layer modes of an air interface protocol architecture, the protocol architecture residing in a base station and/or an access network that includes a base station and access gateway that include distributed and centralized components of the air interface protocol architecture. The traffic load balancing supports various multiplexing scenarios for scheduling communication data under time division multiple access and frequency division multiple access techniques for use in the multi-carrier wireless network.

A technique to replicate unicast flows is described. A plurality of unicast control flows are received at a network element from a plurality of clients. One of the unicast control flows is forwarded to a server. A unicast content flow is received from the server at the network element in response to forwarding the one of the unicast control flows. The unicast content flow is replicated at the network element as a plurality of replicated unicast content flows for transmission to the plurality of clients.

The invention relates to a network for combat control of ground-based units, such as combat vehicles, in real time, in which information is obtained concerning the units comprised in the network for the evaluation of threats and the calculation of a response. According to the invention, the units are divided into clusters (20; 26) with a central unit (21; 27) in each cluster and at least one client unit (22-25; 28-32) in each cluster, which client units are arranged to communicate with the associated central unit. Each unit comprises a control computer, radio, amplifier and antenna for communication with other units. The central unit is arranged to control units comprised in an associated cluster on the basis of the threat evaluation and the response calculation carried out in the central unit on the basis of information communicated from other units, comprising information about the current position, speed, orientation and status of the respective units, and on the basis of information obtained by means of its own equipment, such as active and passive sensors.

A system for an apparatus for extending the physical reach of an InfiniBand network. Methods and apparatus can connect an InfiniBand network to a long distance connection (e.g. WAN) while maintaining full 10Gbit InfiniBand speeds and retaining the semantics specified by the InfiniBand Architecture (IBTA). A system can include an InfiniBand interface, a management block, packet routing, encapsulation/de-encapsulation, bulk memory buffer, and WAN interface, logic and circuits. The invention is applicable to efficiently moving large amounts of data over large distances using a single transport stream.
摘要:
A method of controlling a mobile device based on a network policy, wherein the network policy is stored on the mobile device when a server or acess point is accessed. When a packet is transmitted, it is sent only if it meets the policy parameters as established by the network policy. Parameters may include the type of service or packet, the time of day of the usage, or the maximum tolerable delay permitted.
摘要:
Various methods and apparatus for publishing, subscribing and distributing data, between intra and/or inter-organizations, in formatted, real-time, and/or tunable QOS manner, via one or more channels, over a dynamically formed network of server(s) and clients, serviced publishers and subscribers of the data, are described herein.

A method of supporting a hybrid automatic retransmission request (HARQ) in an orthogonal frequency division multiplexing access (OFDMA) radio access system is disclosed. Preferably, the method comprises receiving a downlink data frame comprising a data map information element and a data burst comprising a plurality of layers, wherein each layer is encoded with a corresponding channel encoder, and wherein the data map information element is configured to support multiple antennas to achieve space time transmit diversity by providing control information associated with each one of the plurality of layers, wherein the control information comprises allocation of acknowledgement status channels corresponding to the plurality of layers, and transmitting in an uplink data frame a plurality of acknowledgement status, each acknowledgement status being associated with whether a corresponding layer of the plurality of layers is properly decoded.

Un aparato para comunicación simultánea e integrada de voz y datos denominado Teledatáfono que dispone de los componentes, programas e interfaces necesarias para facilitar comunicaciones de voz enviando o recibiendo tanto señales de audio por la Red Pública Telefónica Conmutada (PSTN) como paquetes con protocolo IP por la Red Pública de Conmutación de Paquetes Internet, caracterizado por constituir una unidad compacta e integrada compuesta por teléfono convencional, teléfono IP, router, placa o chip de encriptación propietaria de paquetes, unidad de control, y módulo de interface para acceso a Internet no telefónico; permitir que una computadora o red de computadoras conectadas al router puedan navegar por Internet en forma simultánea con una comunicación telefónica IP o convencional; generar por si mismo todos los paquetes IP de señalización necesarios para establecer una llamada telefónica IP con otro teledatáfono, sin depender de una central telefónica, de un servidor central o de una placa de interface centralizada, que oficie de nexo, intermediario o concentrador, sean todos estos equipos públicos o privados; enviar y recibir llamadas telefónicas IP hacia y desde cualquier lugar del mundo sin depender en forma cautiva de un único servidor central sino registrándose como usuario en cualquier Proveedor de Servicios de Valor Agregado de Internet (ISP); interconectarse dentro de una red de área local permitiendo que cada uno de los usuarios, con su propio teledatáfono, efectúe llamadas telefónicas IP y navegue en forma simultánea desde su computadora Una llamada telefónica efectuada por Internet con Protocolo IP con un teledatáfono permite hablar todo el tiempo que se desee, sin ningún costo adicional de pulsos telefónicos. Con la cuota mensual del acceso a Internet de Banda Ancha que ofrece un proveedor de acceso a Internet (ISP), cualquier usuario podrá hablar 24 horas por día, 30 días al mes, y, simultáneamente, navegar por Internet desde su computadora o red de computadoras.
摘要:
This application presents Link Encapsulation Method (LEP) Used to Multiple Services Ring (MSR). LEP used to MSR is provided for default use on a bi-directional symmetric counter-rotating two fibre optical rings, and can also be changed to use of single fibre ring, link-type and broadcast topology. Primary optical transport mechanism is defined to leverage the low cost Wide Area Interface Sublayer (WIS) of 10Gigabit Ethernet (IEEEP802.3ae) as an aggregate pipe. SDH/SONET physical transport is also supported. The service tributary interfaces used to LEP are defined to support Ethernet, TDM Circuit Emulation (including the emulation of G.707 SDH circuit Transport of TU-11, TU-12 or TU-2, G.702 PDH circuit Synchronous and asynchronous circuit transport, Video signal, Voiceband signal, Digital channel supported by 64 kbits/s-based ISDN) and/or an aggregate pipe of other MSR span with a lower rate than that of this aggregate pipe. LEP supports node based protection, tributary based 1+1, 1:1 an 1:N protection, tributary based multicast, tributary bandwidth Limitation, tributary bundle, tributary Line-Speed Filtering, tributary Mirroring, and is also defined to support forwarding of the MSR data link frame (also being a tributary) similar to functionality found in a more complex routing data system.
