Intelligent network streaming and execution system for conventionally coded applications
An intelligent network streaming and execution system for conventionally coded applications provides a system that partitions an application program into page segments by observing the manner in which the application program is conventionally installed. A minimal portion of the application program is installed on a client system and the user launches the application in the same ways that applications on other client file systems are started. An application program server streams the page segments to the client as the application program executes on the client and the client stores the page segments in a cache. Page segments are requested by the client from the application server whenever a page fault occurs from the cache for the application program. The client prefetches page segments from the application server or the application server pushes additional page segments to the client based on the pattern of page segment requests for that particular application. The user subscribes and unsubscribes to application programs, whenever the user accesses an application program a securely encrypted access token is obtained from a license server if the user has a valid subscription to the application program. The application server begins streaming the requested page segments to the client when it receives a valid access token from the client. The client performs server load balancing across a plurality of application servers.

Managing web tier session state objects in a content delivery network (CDN)
Business applications running on a content delivery network (CDN) having a distributed application framework can create, access and modify state for each client. Over time, a single client may desire to access a given application on different CDN edge servers within the same region and even across different regions. Each time, the application may need to access the latest “state” of the client even if the state was last modified by an application on a different server. A difficulty arises when a process or a machine that last modified the state dies or is temporarily or permanently unavailable. The present invention provides techniques for migrating session state data across CDN servers in a manner transparent to the user. A distributed application thus can access a latest “state” of a client even if the state was last modified by an application instance executing on a different CDN server, including a nearby (in-region) or a remote (out-of-region) server. |

Evaluation of current capacity levels of resources in a distributed computing system
In general, this disclosure describes techniques of managing resources in a service-oriented distributed computing system. As described in this disclosure, a control node automatically manages the system such that the system has sufficient capacity to satisfy an agreement to provide a given level of a service. In order to automatically manage the system, the control node evaluates the current capacity levels of resources in the system. The current capacity levels are indicative the capacity of resources to perform certain acts. The capacity of the resources to perform these acts may be indicative of whether the system is able to provide the given level of the service. Because capacities provided by the resources change as the resources start, the control node uses a predicted pending capacity function to evaluate whether resources that are currently starting will be sufficient to satisfy the level of the service when completely started. |

Zeroing-out LLRs using demod-bitmap to improve performance of modem decoder
A demodulation mask bitmap includes binary mask values. Each mask value corresponds to an input resource element to a demodulator. For each mask value of a first state, a demodulation engine of the demodulator is not clocked and the demodulator outputs a zero-valued resource element.

A demodulation mask bitmap is designed to mask pilot resource elements and corrupted resource elements. Power is conserved by not clocking the demodulation engine for corrupted and pilot resource elements. Subsequent LLR generation and decode operations are simplified. Decoder performance is improved because the decoder does not decode LLR values derived from corrupted resource elements and/or resource elements not relevant to the reconstruction of a communicated message. |

Scanning methods and apparatus for mobile devices in wireless local area networks for reduced power consumption
One illustrative method for reducing power consumption in a mobile communication device of a wireless local area network (WLAN) involves the steps of identifying a communication signal quality value between the mobile device and a wireless access point of the WLAN with which the mobile device is currently associated; determining an initial timer value based on a predefined relationship with the communication signal quality value where, as the communication signal quality value decreases, the initial timer value correspondingly decreases; initializing a scan trigger timer with the initial timer value and running the scarf trigger timer; and upon expiration of the scan trigger timer: causing a scanning operation to be performed for identifying one or more wireless access points in a coverage region; and repeating the acts of identifying, determining, initializing and running the scan trigger timer, and causing the scanning operation to be performed. Preferably, the mobile device operates to refrain from performing scanning operations altogether when the communication signal quality value is greater than a scan trigger threshold value. The scan trigger threshold value may be derived from or calculated based on a previously-received or last-sampled communication signal quality value of the wireless access point sampled at a time when the mobile device chose to reassociate with a different wireless access point of the WLAN. |

Distributed synchronous batch reconfiguration of a network
A novel alternative concept for handling dynamic provisioning changes and ongoing network reconfiguration and incremental reoptimization in general. A prime motivation is concern about the dependency of existing concepts for dynamic provisioning on the real-time coherence of databases of network state at diverse geographic locations. Not only is the continual updating of such global state everywhere in the network an intensive real-time load, but inevitable incoherencies pose hazards in network operation. The alternative proposal is a framework that makes use precise time synchronization and the computational power of network nodes to solve identical local instances of incremental reoptimization problems in situ. The new scheme removes the database coherency hazard, reduces signaling volumes, and increases resource efficiencies in service provisioning. It also provides a framework in general for continually ongoing incremental or (if desired) total reoptimization of network configuration. The proposal also points directions towards some new research questions such as implementation of optimization models for identical solution on disparate platforms and definition of a variety of incremental batch reoptimization problems. It is thought that this may be one of the first practical application concepts for transport network management that would involve on-line embedded use of operations research methods in communication networks. |

Distinguishing between connectivity verification availability and forwarding protocol functionality in a computer network
In one embodiment, a local network device may determine an inability to establish a connectivity verification protocol (e.g., Bidirectional Forwarding Detection, “BFD”) session to a remote network device, such as from unreturned control messages.

In response to receiving or not receiving the echo message, the local network device may thus determine whether the forwarding protocol is functioning between the local and remote network devices. In this manner, the local network device may determine whether an inability to establish a connectivity verification protocol session is due to an inability to forward packets between the devices, or due to the connectivity verification protocol not working (or not being configured) on the remote network device. |

Uplink scheduling DSF wireless networks
In network-based uplink scheduling, users are scheduled by the network for uplink communication between a user side and a network side. In this context, the invention provides an efficient estimation of User Equipment (UE) buffer status on the network side such as at Node B (20), for each of a number of users (10), and determines an uplink scheduling priority order of the users based on the network-estimated buffer status information.

In this way, the UE buffer status may be considered in the uplink scheduling procedure without explicit UE buffer status reports (that would waste valuable uplink transmission resources) from the UE side. This means that efficient scheduling and optimal exploitation of the uplink transmission resources are ensured, with clearly improved system performance as a result. |

Parallel-path acoustic telemetry isolation system and method
An acoustic telemetry isolation system and method for use with tubular assemblies such as drillpipe and production tubing includes an acoustic wave transmitter and an acoustic isolator. A “down” wave propagated toward the isolator is reflected back substantially in phase with an “up” wave propagated from the acoustic wave source away from the isolator.

The construction of the isolator utilizes a specified combination of waves traveling in parallel in materials whose properties aid the beneficial combination of reflected and transmitted waves. The design of the isolator is to generally provide a bandstop filter function, thereby aiding the frequency isolation of an acoustic transmitter over a passband that may be constrained by the geometry of drill pipe or components of production tubing. It causes substantially all of the emitted wave energy to travel in a chosen direction along the drill pipe, thus aiding the efficiency of acoustic telemetry in the pipe. |
