摘要： A method for the efficient routing of data packets across a plurality of routers when a link is unavailable which includes connecting a plurality of nodes in a network using a plurality of routers having a plurality of links between the routers, informing the routers in the network when one or more of the links in the network will be unavailable at a specified time in the future, recalculating the routing tables to determine the most efficient routing paths when the links in the network become unavailable and, when the time in the future arrives, switching the routers in the network to the new routing tables at the same time.

摘要： The present invention provides methods and apparatuses for controlling a gain of an optical fiber amplifier. Gain circuitry operates in an opened loop configuration and uses a predetermined function relating a power variation of at least one wavelength region with a pump power adjustment for at least one optical pump. Two approximate linear relationships between the input signal power variations and the required pump power adjustments are utilized in controlling the Raman fiber amplifier. Each approximate linear relationship includes at least one linear coefficient that relates a power variation for a specific wavelength region and a power adjustment of a specific Raman pump. The dynamic gain control technique is applicable to an Erbium-doped fiber/waveguide amplifier. Also, a dynamic gain control technique controls a backward-pumped Raman amplifier, in which the power variation is determined at one geographical location and the optical pumps are controlled at another geographical location.

摘要： The time taken to learn a model from training examples is often unacceptable. For instance, training language understanding models with Adaboost or SVMs can take weeks or longer based on numerous training examples. Parallelization thought the use of multiple processors may improve learning speed. The invention describes effective methods to distributed multiclass classification learning on several processors. These methods are applicable to multiclass models where the training process may be split into training of independent binary classifiers.

摘要： A premises, connected to receive broadband service(s) and also connected to a cable system, is provided with a broadband interface which connects to in-premises cabling which is coupled to consumer receivers such as a television sets, PDAs, laptops. Connected to the broadband interface is an adjunct device which channels broadband, data and voice signals supplied to an in-premises wireless system as distinguished from the signals supplied to the cable connected consumer receivers. The adjunct device formats the broadband and voice signals or any broadband service into packet format suitable for signal radiation and couples them to the in-premises coax cabling, via a diplexer, at a first selected location. At a second cable location a second diplexer, connected to the cable, separates the broadband, data and voice signals and couples them to a signal radiation device (i.e., an RF antenna or leaky coaxial cable) which radiates the signal to the immediate surrounding location. Various devices, near to the second cable location for specific services, receive the wireless signals (i.e., broadband, data and voice) from the radiating antenna.

摘要： The present invention provides a method and system for assuring H.323 alias address portability to an H.323 user in real-time H.323 multimedia communications where the H.323 user is registered with a home gatekeeper for the home zone of the H.323 user. Alias address portability may be obtained using a central database that is known to the administrative zones and is used for alias address mapping, or alternatively, may be obtained by using a distributed database. The method may be implemented by: sending, by the H.323 user, a message with a called H.323 entity's alias address, to the home gatekeeper to originate a call to the called H.323 entity; confirming that the alias address, services, and service providers are portable; converting the alias address to a called routable alias address for the called H.323 entity and sending the alias address to the H.323 user; and placing the call to the called H.323 entity.

摘要： A method and a system is disclosed for providing access in a centralized manner to a communications medium that is suitable for allowing use of a plurality of Home Phoneline Network Association (HPNA) v2 frames. A plurality of messages are transmitted between a first enhanced station and a second enhanced station. Each transmitted message is transmitted in an enhanced frame that has timing to allow an Inter-Frame Gap (IFG). A blocking signal, such as a sine wave signal and a cosine wave signal, is transmitted during at least one IFG between enhanced frames to mask the presence of the IFG to a non-enhanced STA. Alternatively, the blocking signal can be transmitted during at least one reply message. Contention-free access to the communications medium is also provided by transmitting messages in a highest priority level available in an HPNA v2 frame.
