Secure electronic message transport protocol
An electronic message transport protocol applies two distinct sub-protocols, a message transport protocol and an encryption key management protocol, which operate in tandem to provide enhanced security. The protocol may employ an existing SMTP infrastructure to transport secure email messages, and a key server implementing the key management protocol to transport key packets associated with the secure email message. However, the protocol need not be limited to email, and may be applicable to other electronic message applications. The message transport protocol permits communicating parties to obscure their identities to enhance security. The key management protocol supports message security, and allows senders to control access to messages even after they have been transmitted. The message transport protocol permits the sender to encrypt the entire message and utilizes the key management protocol for exchange of necessary keys. The message transport protocol relies on a group addressing scheme to obscure individual sender and recipient identities. |

Method of universal file access for a heterogeneous computing environment
An architecture and system are described that provide a unified file access service within in a managed computing environment composed of diverse networks, computing devices, and storage devices. The service provides mechanisms for remotely accessing the file systems of any managed computer or disk snapshot, independently of the computer's current state (powered on, suspended or powered off), its location within the environment, its hardware type (virtual vs. physical), its operating system type, and its file system formats. The system isolates centralized FPAs from the details of clients, proxies and storage elements by providing a service that decomposes offloaded file system access into two steps. A FPA or a requester acting on behalf of the FPA first expresses the disk set or the computer containing the file systems it wishes to access, along with requirements and preferences about the access method. The service figures out an efficient data path satisfying the FPA's needs; and then automatically configures a set of storage and computing resources to provide the data path. The service then replies with information about the resources and instructions for using them. The FPA then accesses the requested file systems using the returned information. |

Applying abstraction to object markup definitions
Techniques for enabling a validating parser to interpret a schema, where that schema may have been extended to multiple levels, and to perform the validation of a structured document according to the extended schema while still allowing a consumer application to request objects or events that are cast at some different level of the schema (including the base schema). Validating the source document according to an extended (i.e., more specific) schema enables improved detection of syntax errors. At the same time, casting objects and events from the parsed document to a level requested by the consumer application allows the consumer to receive only those objects or events for which it is adapted, without requiring the consumer application to include extra code to deal with objects or events it does not recognize in the parser's output. Preferably, the parser simply discards those objects or events which this consumer is not interested in receiving. |

A self-managing workload repository (AWR) infrastructure useful for a database server to collect and manage selected sets of important system performance statistics. Based on a schedule, the AWR runs automatically to collect data about the operation of the database system, and stores the data that it captures into the database. The AWR is advantageously designed to be lightweight and to self manage its use of storage space so as to avoid ending up with a repository of performance data that is larger than the database that it is capturing data about. The AWR is configured to automatically capture snapshots of statistics data on a periodic basis as well as purge stale data on a periodic basis. Both the frequency of the statistics data capture and length of time for which data is kept is adjustable. Manual snapshots and purging may also be performed. The AWR captured data allows for both system level and user level analysis to be automatically performed without unduly impacting system performance, e.g., by eliminating or reducing the requirement to repeat the workload in order to diagnose problems. |

MDN-less SMS messaging (network solution) for wireless M2M application
Machine-to-Machine (M2M) communications, for various telemetry applications, such as meter reading, alarm applications or the like, utilize data communication service via a public mobile/wireless communication network, such as the short message service (SMS). However, such M2M communications may involve a large number of clients. To avoid the need to assign a telephone number, such as a mobile directory number (MDN) or the like, to each of the many remote M2M clients, routing through the network is based on another type of MSID (Mobile Station Identifier), such as the MIN (Mobile Identifier Number) or the IMSI (International Mobile Station Identifier) of the client. SMS messages transmissions originating at a client use a short code for the M2M application address, and SMS messages intended to terminate at a client use the MIN or IMSI as the routing address for the M2M device. |

Benign interference suppression for received signal quality estimation
A receiver circuit suppresses effects of “benign” impairment from the calculation of received signal quality estimates, such that the estimate depends primarily on the effects of non-benign impairment. For example, a received signal may be subject to same-cell and other-cell interference plus noise, which is generally modeled using a Gaussian distribution, and also may be due to certain forms of self-interference, such as quadrature phase interference arising from imperfect derotation of the pilot samples used to generate channel estimates for the received signal. Such interference generally takes on a distribution defined by the pilot signal modulation, e.g., a binomial distribution for binary phase shift keying modulation. Interference arising from such sources is relatively “benign” as compared to Gaussian interference and thus should be suppressed or otherwise discounted in signal quality calculations. Suppression may be based on subtracting benign impairment correlation estimates from total impairment correlation estimates, or on filtering the benign impairment in channel estimation. |

RF domains
A wireless access point broadcasts a unique RF domain identifier for each supported service set per radio. Within a wireless local area network (“WLAN”) the RF domain identifier is unique for each supported service set, and hence identifies the service set. In addition to identifying the service sets supported by the access point, RF domain identifiers may be used to adjust transmit power in order to differentiate service sets. For example, if a first access point receives a beacon with an RF domain identifier transmitted by a second access point, the transmit power of communications associated with the service set associated with the received RF domain identifier is reduced at the first access point if that service set is also supported on the same radio by the first access point. In one embodiment the first and second access points both reduce transmit power until the beacons are no longer received by the respective nearby access point. The transmit power of communications associated with other service sets and other radios are not effected by the transmit power reduction, i.e., the access point may reduce transmit power of overlapping service set communications while contemporaneously transmitting communications of non-overlapping service sets at full power. |

Method for handling channel failures in an automatically switched optical network
The present invention discloses a method for handling channel failures in an Automatically Switched Optical Network (ASON). When a channel alarm occurs, the head service node decides whether the channel alarm is incurred by a channel failure according to the alarm message or alarm information. If so, the head and end service nodes continue to locate whether the channel failure is inside or outside the network by combining local detection and message notification. If the channel failure is an internal failure, rerouting is activated to locate and remove the channel failure. When this method is used to locate a channel failure, the amount of information exchanged is small. The method may quickly identify the accurate position of a failure inside the network, improve the efficiency in removing failures, and minimize the damages to services, with little harm to equipment functioning and network performance. |

Self-configurable telephony architecture
Techniques are disclosed for automating the process of configuring a telephone system. More specifically, the techniques disclosed herein enable a telephone system to monitor the behavior of users of that system and to configure the users' preferences based on their observed behavior. For example, the system may observe that a particular user frequently dials a particular telephone number manually. In response to this observation, the system may automatically configure the frequently-dialed telephone number as a speed dial number for that user. As a result, the user may dial the number in the future by pressing a speed dial button rather than by entering the number manually. Such an automatic configuration process may enable the telephone system to be adapted to its users' needs more quickly and accurately, and with less effort on behalf of the users, than is possible using conventional systems that require their users to perform configuration manually. |

Methods and apparatus for communicating using a DC tone
Special DC tone treatment in a wireless communications system, e.g., an OFDM system, is discussed. In the downlink, a wireless terminal receiver introduces self-interference at the DC tone from the RF/baseband conversion. A base station every so often does not transmit on the downlink DC tone while continuing to transmit on other downlink tones. Wireless terminals measure received signal on the downlink DC tone during the time of suspended DC tone transmission, estimate self-interference and apply a correction to other received downlink DC tones. In the uplink DC tone interference is a composite of the assigned wireless terminal transmitter's baseband/RF conversion self-interference and air link noise. During one symbol interval of an N symbol interval dwell, the uplink DC tone is reserved for a special modulation symbol, which is a predetermined function of the other N-1 modulation symbols. At the base station, its receiver receives a set of modulation symbols conveyed by the uplink DC tone for a dwell, calculates the average DC component and corrects the received N-1 modulation symbols. |

Thereafter, the gain controller detects for low total received power, e.g., by comparing the detected total received power against a predetermined threshold. The gain controller transitions to a higher gain state if low total received power is detected and maintains the current gain state otherwise. |

A balanced transmitter up-converts a baseband signal directly from baseband-to-RF. The up-conversion process is sufficiently linear that no IF processing is required, even in communications applications that have stringent requirements on spectral growth. In operation, the balanced modulator sub-harmonically samples the baseband signal in a balanced and differential manner, resulting in harmonically rich signal.

In embodiments of the invention, the control signals have pulse widths (or apertures) that operate to improve energy transfer to a desired harmonic in the harmonically rich signal. A bandpass filter can then be utilized to select the desired harmonic of interest from the harmonically rich signal. The sampling modules that perform the sampling can be configured in either a series or a shunt configuration. In embodiments of the invention, DC offset voltages are minimized between the sampling modules to minimize or prevent carrier insertion into the harmonic images. |

Block transform and quantization for image and video coding
An improved method and block transform for image or video encoding and decoding, wherein transformation and inverse transformation matrixes are defined such that computational complexity is significantly reduced when encoding and decoding. For example, in the two-dimensional inverse transformation of de-quantized transform coefficients into output pixel information during decoding, only four additions plus one shift operation are needed, per co-efficient transformation, all in sixteen-bit arithmetic. Transformations provide correct results because quantization during encoding and de-quantization (sixteen bit) during decoding, via the use of one of three tables selected based on each coefficient's position, have parameter values that already compensate for factors of other transformation multiplications, except for those of a power of two, (e.g., two or one-half), which are performed by a shift operation during the transformation and inverse transformation processes. Computational complexity is significantly reduced with respect to other known transforms without adversely impacting compression or quality. |

Method and system for generating packet delay variation with a uniform distribution
Embodiments of the present invention provide packet timing recovery stress testing by generating packet delay variation (PDV) with a uniformly distributed probability density function (PDF). A delay-step method determines a delay for each packet in a stream of packets generated at a regular interval.

Phantom use in DSL systems
Superimposing phantom-mode signals reinforces existing differentially driven DSL downstream signals in a vectored binder of DSLs or reinforces upstream vectored signals in a binder of differentially excited twisted pairs, thus expanding the extra transmission modes of the previous GDSL multi-wire two-sided-excitation invention to the case where coordination can only occur on one-side of the binder. Each pair is treated as a common-mode antenna with respect to earth ground, with some pairs selectively excited at the transformer center tap at the transmit end with respect to a common (earth or chassis) ground reference. Corresponding receivers on other non-excited pairs sense the signals between their center taps and a ground at the opposite ends of the lines to the exciting transmitters. A dual use with hybrid circuits allows the receiving circuit to also have an upstream transmitter and an upstream-sensing receiver on the center tap of the opposite side of an adjacent wire. |
