Publication number: 20190370027Abstract: A baseline visualization is parsed to identify visual elements in the baseline visualization. A user interface allows a user to configure a lens overlay that associates an overlay shape, with corresponding data obtained through an API, from an external source. The data and shape in the lens overlay are also associated with a visual element in the baseline visualization. The lens overlay is separate from the baseline visualization. When the baseline visualization is displayed, the lens overlay, is displayed concurrently with the baseline visualization so that shapes in the lens overlay are displayed at a configured location and position relative to visual elements in the baseline visualization.Type: ApplicationFiled: May 31, 2018Publication date: December 5, 2019Inventors: Terence Hung Bun Lee, Neha Bajpai, Ade William

Publication number: 20170272541Abstract: 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).Type: ApplicationFiled: March 21, 2016Publication date: September 21, 2017Applicant: LinkedIn CorporationInventors: Edward J.

Patent number: 9535963Abstract: 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.Type: GrantFiled: September 18, 2015Date of Patent: January 3, 2017Assignee: LinkedIn CorporationInventors: Srinath Shankar, Robert W.

Patent number: 9185024Abstract: 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.Type: GrantFiled: March 1, 2011Date of Patent: November 10, 2015Assignee: The Chinese University of Hong KongInventors: Yangyang Lin, Yiu Bun Lee

Patent number: 8787378Abstract: The apparatus, systems, and methods described herein may operate to receive at least one data packet from a transmitter connected to a first network. A packet forwarding time may be scheduled for the at least one data packet. The at least one data packet may be forwarded to a receiver connected to a second network based on the packet forwarding time such that transmission of the at least one data packet prevents a buffer overflow at the receiver.Type: GrantFiled: December 27, 2011Date of Patent: July 22, 2014Assignee: The Chinese University of Hong KongInventors: Yiu Bun Lee, Wing San Wan

Publication number: 20140101508Abstract: An embodiment of the invention includes an efficient error-control system and method for recovering packet losses, especially losses in distributing multicast video over broadband residential networks. Preferably, unlike most existing error-control algorithms designed for Internet multicast, the system and method does not employ substantial feedback suppression. Preferably, the system and method does not employ substantial multicasted retransmission. Preferably, the system and method does not employ substantial parity retransmission. Preferably, the system and method does not employ substantial local loss recovery. The system and method integrates two existing classes of error-control algorithms: Automatic Repeat Request (ARQ) and Forward Error Correction (FEC), to reduce traffic overhead and achieve scalability.Type: ApplicationFiled: September 13, 2013Publication date: April 10, 2014Applicant: SONY CORPORATIONInventor: Jack Yin-Bun Lee

Patent number: 8577985Abstract: 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.Type: GrantFiled: December 28, 2011Date of Patent: November 5, 2013Assignee: The Chinese University of Hong KongInventor: Yiu Bun Lee

Patent number: 8509080Abstract: 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.Type: GrantFiled: June 23, 2010Date of Patent: August 13, 2013Assignee: The Chinese University of Hong KongInventors: Jack Yiu-Bun Lee, Wing-San Wan
