摘要： A capability for controlling a size of a congestion window of an information transmission connection (ITC) is provided. The size of the congestion window of the ITC may be controlled based on a threshold, which may be based on an ideal bandwidth-delay product (IBDP) value. The IBDP value may be based on a product of an information transmission rate measure and a time measure. The information transmission rate measure may be based on a target information transmission rate for the ITC. The time measure may be based on a round-trip time measured between a sender of the ITC and a receiver of the ITC. The threshold may be a cap threshold where the size of the congestion window is prevented from exceeding the cap threshold. The threshold may be a reset threshold which may be used to control a reduction of the size of the congestion window.

摘要： A method of sending hypertext transfer protocol (HTTP) adaptive streaming (HAS) content from a content source to a client over a transmission control protocol (TCP) connection between the content source and the client may include receiving a request for one or more first HAS data chunks from the client; sending the one or more first HAS data chunks to the client; generating idle delay values indicating an amount of delay in the TCP connection during an idle time period, the idle time period being a time period over which no HAS data chunks are being sent from the content source to the client; receiving a request for a second HAS data chunk from the client; setting the size of a starting TCP congestion window based on the idle delay values; and sending the second HAS chunk to the client using the starting TCP congestion window.

摘要： A process for the preparation of 10-methoxycarbamazepine, an important intermediate in the preparation of 10-oxo-10, 11-dihydro-5H-dibenz(b,f)azepine-5-carboxamide(oxcarbazepine) from 10-methoxy-5H-dibenz(b,f)azepine(10-methoxyiminostilbene), is disclosed, which process comprises reacting 10-methoxyiminostilbene with cyanic acid (HOCN) in the presence of a mild acidic reagent in a solvent. Also disclosed is an improved method for the hydrolysis of 10-methoxycarbamazepine to oxcarbazepine, which method comprises carrying out the hydrolysis in a biphasic system chosen such that the oxcarbazepine is substantially insoluble in both phases, whereas the by-products or impurities are soluble in at least one of the phases. The oxcarbazepine thereby prepared is an anticonvulsant, and has been proposed for use as an anti-epileptical agent in the treatment of AIDS-related neural disorders, and for the treatment of Parkinson's disease and/or Parkinsonian syndromes.

摘要： A system and method for connecting traffic along a communications network is accomplished by rerouting traffic upon the detection of a fault condition along a primary connection path. A laser-diode transmitter, uniquely tagged, transmits a specific bit pattern signature header unique to the transmitter at the beginning of a predetermined transmission sequence. The network recognizes the unique identifier and configures the network to route all traffic from the identified transmitter along a specific path to its intended destination.

摘要： The instant invention allows control of voice transmission from end user to end user by common channel signaling without the repeated conversion delays encountered by entering and exiting the standard voice network and an ATM network. The control is accomplished in parallel over the standard public switch telephone network while the voice “data” is transported over an ATM “data” network. Each ATM node has with it a co-located PSTN voice switch. A pair of control links are used to communicate between the two co-located ATM and TDM switches.

摘要： Systems and methods are disclosed for adjusting resource profiles which are used by user equipment (UE) to pre-fetch assets from content providers. In one embodiment, a recommender system receives a resource profile from a UE. The resource profile indicates content providers that have assets for the UE to download in advance during a pre-fetch operation. The resource profile also defines a percentage of UE resources allocated to each of the content providers for downloading the assets during the pre-fetch operation. The recommender system then adjusts the percentages of the UE resources in the resource profile for the end user to generate an updated resource profile for the end user, and transmits the updated resource profile to the UE for use in one or more subsequent pre-fetch operations.

摘要： Systems and methods are disclosed for pre-fetching assets from content providers to user equipment (UE). In one embodiment, the UE initiates a pre-fetch operation to download assets from content providers in advance of an end user requesting the assets. The UE accesses a resource profile for the pre-fetch operation that indicates the content providers that have assets for the UE to download in advance for local storage on the UE, and defines a percentage of UE resources allocated to each of the content providers for downloading the assets during the pre-fetch operation. The UE may then download the assets from the content providers based on the resource profile, and store the assets in a local memory.

摘要： A system for routing of data traffic on a communications network comprising a plurality of gatekeepers interlinked to form a network wherein the plurality of gatekeepers control bandwidth and routing of data packets towards destination terminals. A plurality of routers aggregate real time flow of data packets through said gatekeepers, and terminals which are connected to the network via the gatekeepers, negotiate connection parameters. Real time flow of said data packets is directed from one end point terminal to another utilizing the gatekeepers and the routers.
