  • Publication number: 20190244608
    Abstract: An apparatus supports smart assistant services with a plurality of smart service providers. The apparatus includes an audio device that receives a speech signal having a user utterance, captures the user utterance when the user utterance includes a user wake word, and sends the captured utterance to a backend computing device. The backend computing device replaces the user wake word with specific wake words associated with different smart service providers. The processed utterances are then sent to selected smart service providers. The backend computing device subsequently constructs feedback to the user utterance based on voice responses from the different smart service providers. The backend computing device then passes a digital representation of the feedback to the audio device, and the audio device converts the digital representation to an audio reply to the user utterance.

  • Publication number: 20170272541
    Abstract: A system, method, and apparatus are provided for locally enforcing quotas on resources within a computing environment (e.g., a data center, a computing cluster) that includes multiple brokers, gateway servers, or other entities that control access to the resource(s). Instead of using global access statistics provided by all gateways, each server individually allows or denies requested access to a resource based on whether the requesting client has already exceeded its quota (or would exceed its quota if the request is approved). A client associated with a given call to a resource may be identified using a tuple formed from identifiers of multiple services in the call stack, such as a first service (e.g., a front-end or user-facing service) and an immediate service (e.g., a final service in the stack prior to receipt of the call at a gateway, broker, or other entity that manages access to the controlled resources).

  • Patent number: 9535963
    Abstract: In order to request desired information from a graph database, a system executes a query against the graph database. The graph database may store a graph that includes nodes, edges between the nodes, and predicates to represent and store data with index-free adjacency. Moreover, the query may identify a first edge associated with a predicate that specifies one or more of the nodes in the graph. In response to the query, the system receives a result that includes a subset of the graph. In particular, the subset of the graph may include the desired information expressed within an associated structure of the graph.

  • Patent number: 9185024
    Abstract: A method and a tool based on achievable bandwidth as a metric are provided for selecting paths for overlay construction in an application layer multicast system. An in-band bandwidth probing tool according to the invention can estimate achievable bandwidth, i.e., the data throughput that can be realized between two peers over the transport protocol employed. The tool can determine the amount of extra bandwidth available in the target network path so that excess data traffic can be diverted from congested path without causing new congestion in the target path.

  • Patent number: 8577985
    Abstract: A pull-based parallel video server system and method of implementation useful in an on-demand video system includes a plurality of slave admission schedulers operating in parallel with a master admission scheduler to back up the master admission scheduler that controls access to an array of pull-based video servers according to a protocol that accounts for jitter and loss of packets, as well as network delays. A transport protocol is provided that improves video data throughput under such conditions. To determine the architecture and functional requirements of the redundant admission schedulers, an analytical tool in the form of a performance model has been developed that incorporates network delays, delay jitters and packet losses on the communication links between the clients, schedulers and servers.

  • Patent number: 8509080
    Abstract: In a packet communication system with large bandwidth delay product (BDP) and employing Transmission Control Protocol (TCP), the reported advertised window size as advertised by a receiver is employed only as an indication of window size and not as a throughput limit so that more data is sent than the amount specified by the advertised window size. Since the receiver can process all incoming TCP packets, the receiving buffer is consistently near empty. Since the TCP's advertised window size is not accepted as the absolute amount of buffer space available at the receiver, the sender is not constrained by the absolute value of the receiver's advertised window size and instead can transmit more data than the absolute value of the advertised window, enabling the system to increase the actual window size without modifying the link ends. This improved large-BDP-capable protocol is denoted TCP-SC.

  • Patent number: 8488461
    Abstract: In a peer-to-peer asymmetric communication environment, an adaptive upload Data Rate Control element—called Adaptive-DRC—is used to detect increase in data return-trip time (RTT) caused by the congestion associated with the uploading of data in an uplink which in turn impacts on downloading data on an associated downlink, namely a downlink sharing resources with the uplink. Using Adaptive-DRC, the congestion is detected and thereupon adjustments to are made to allow continued communication. Adaptive-DRC comprises: (i) RTT estimation; (ii) detection of the onset of congestion, herein pre-congestion detection; and (iii) adaptation of the upload data rate limit. Two specific embodiments are contemplated, namely two versions of Adaptive-DRC wherein the difference lies in the upload data rate limit adaptation technique.
