20090293055 | Central Office Based Virtual Personal Computer - A virtual personal computer is implemented in a communication system comprising a plurality of central offices each of which communicates with a plurality of client devices over a corresponding access network. A given one of the central offices comprises at least one compute server and at least one storage server. The virtual personal computer is configured by allocating physical processing resources of the compute server and physical storage resources of the storage server to that virtual personal computer. User access is provided to the virtual personal computer via one of the client devices. The virtual personal computer can be dynamically reconfigured by altering the allocation of at least one of the physical processing resources and the physical storage resources to the given virtual personal computer responsive to particular applications selected by the user to run on the given virtual personal computer. | 11-26-2009 |
20110255866 | SYSTEM AND METHOD FOR SCHEDULING TIMESLOTS FOR TRANSMISSION BY OPTICAL NODES IN AN OPTICAL NETWORK - A signal strength corresponding to an incoming optical burst from each of a plurality of optical nodes is measured. The measurements can be performed at system start-up, configuration/installation of the optical nodes and/or at certain intervals of operation of the optical nodes. Signal strength information for the optical nodes based on the measurements is stored in memory. When scheduling the optical nodes for transmission, a preferred transmission order is determined in response to the stored signal strength information. In an embodiment, the preferred order is determined to reduce differences in signal strength levels between consecutive optical bursts. | 10-20-2011 |
20140126919 | Method And Apparatus For Processing Bit-Interleaved Data Traffic In A Communication Network - A manner of processing bit-interleaved data traffic in a communication network. In the increasingly-common scenario where data traffic is bit interleaved and scrambled using a PRBS (pseudo-random binary sequence) before it is transmitted from a sender to a receiver, the receiver is configured to receive the transmitted bit stream and decimate it, that is, remove the bits of the bit stream that are allocated for the receiver, prior to descrambling. To accomplish this, the receiver employs an LFSR (linear feedback shift register) similar or identical to the one used by the sender to scramble the data. The LFSR is initialized by employing helper bits inserted by the sender or an initialization unit, and may employ other techniques for phase adjustment or state skipping depending on the nature of the transmitted bit stream. | 05-08-2014 |
20140341593 | Method And Apparatus For Optical Transmission In A Communication Network - A manner of mitigating the self heating effect of a laser or other light source such as a laser in a network node of a communication network. A self-heating mitigation module is provided, the self-heating mitigation module includes one or both of a self-heating adjustment module to accelerate self heating at the beginning of a transmission and a sub-threshold lasing module that applies a sub-threshold current between transmissions. The self-heating adjustment module and the sub-threshold lasing module are preferable both used together and driven by a common signal, for example the burst_enable signal that facilitates transmission from the light source. | 11-20-2014 |

20090028256 | METHOD AND APPARATUS FOR SENSING SIGNALING PARAMETERS IN A WIRELESS COMMUNICATIONS NETWORK - A new channel is added to FLO networks that carries embedded signaling parameter information. The design is such that regardless of the actual values of the signaling parameters conveyed, a receiver will be able to demodulate this new channel. Moreover, the addition of the new channel does not render a FLO network that has been so configured to not be backwards-compatible with existing devices. | 01-29-2009 |

20100260161 | APPARATUS AND METHODS FOR INTERLEAVING IN A FORWARD LINK ONLY SYSTEM - Methods and devices for encoding and interleaving data packets for broadcast and for de-interleaving and decoding data packets in a communication system eliminate detrimental biasing effects by using pseudo-random M-sequence bit encoding as part of the turbo encoding and decoding. The use of pseudo-random M-sequence bit encoding mitigates biasing effects that may otherwise be introduced if conventional r-c interleaving is applied to long turbo encoded data which would degrade reception in the presence of broadcast interference. | 10-14-2010 |
