  • MINIMIZING DATA LOSS IN ASYNCHRONOUS REPLICATION SOLUTION USING DISTRIBUTED REDUNDANCY
    Publication number: 20090327805
    Abstract: Architecture that reduces data loss resulting from failover in an asynchronous log shipping deployment, but leveraging mid-tier and frontend servers to fill in lost data. In an asynchronous log shipping operation, a replication component asynchronously replicates messaging data to a backend server in accordance with one or more replication operations, which can be updates to databases on the backend server. These databases can include messaging data, such as email address books, mailboxes, etc. A history component maintains a history of replication operations on a frontend server. In the event of a lossy failover, a replay component is used for replaying the replication operations from the history to the backend server.

  • RECOVERY STRATEGY FOR A STREAM PROCESSING SYSTEM
    Publication number: 20170083396
    Abstract: The technology disclosed relates to discovering multiple previously unknown and undetected technical problems in fault tolerance and data recovery mechanisms of modern stream processing systems. In addition, it relates to providing technical solutions to these previously unknown and undetected problems. In particular, the technology disclosed relates to discovering the problem of modification of batch size of a given batch during its replay after a processing failure. This problem results in over-count when the input during replay is not a superset of the input fed at the original play. Further, the technology disclosed discovers the problem of inaccurate counter updates in replay schemes of modern stream processing systems when one or more keys disappear between a batch's first play and its replay. This problem is exacerbated when data in batches is merged or mapped with data from an external data store.

  • Method and apparatus for handling a missed group call in a public safety communication session
    Patent number: 9565540
    Abstract: A communication system is provided that alerts a public safety officer to missed Push-to-Talk (PTT) group calls. The communication system allows a public safety officer's radio to record a last stop working time. A public safety network then can search a missed call list associated with the public safety officer and automatically push a notification of missed PTT group calls to the public safety officer's radio when the radio re-joins the public safety network. Based on the notification, the public safety officer can choose to review or replay any missed calls to avoid missing important information.

  • METHODS FOR ESTABLISHING A SECURITY SESSION IN A COMMUNICATIONS SYSTEM
    Publication number: 20120036567
    Abstract: A security gateway and an initiating device perform methods for establishing a security session. The methods includes the security gateway: receiving a first message from an initiating device, the first message including a first message authentication code; validating the first message using the message authentication code; and responsive to the validating, sending a second message to the initiating device, the second message including a timestamp and further including a second message authentication code for authenticating of the timestamp by the initiating device, wherein the first and second messages are used to establish the security session, and the authenticated timestamp is used for subsequent replay protection of messages between the security gateway and the initiating device. The method further includes the security gateway validating a dynamically assigned IP address for the initiating device to use in authorizing VPN traffic between the two devices.

  • Simple approach to case-based reasoning for data navigation tasks
    Patent number: 5717835
    Abstract: An architecture and key algorithms are presented that simplify the implementation and improve the functionality of knowledge-based systems that employ case-based reasoning for data navigation tasks (e.g., solving help desk problems using a database of past problem instances). The various embodiments of the invention improve on the state-of-the-art in several respects: (a) provides greatly increased flexibility in choosing attributes relevant to a case in that choices are made dynamically at case acquisition instead of statically when the knowledge-based system is designed; (b) increased system flexibility and decreased system complexity by not requiring designers to specify the manner in which attribute values are compared; (c) simplified system design by avoiding the use of similarity metrics; (d) allows for the incremental acquisition of data in problem instances, instead of requiring that all potentially relevant data be collected; and (e) provides a way to explain why a problem solution was chosen.

  • Diagnostic medical ultrasound system having method and apparatus for storing and retrieving 3D and 4D data sets
    Patent number: 7044912
    Abstract: A method and system is disclosed which permits a user to save user defined viewing configuration, also referred to as a bookmark as a separately manipulatable or transferable entity without altering the underlying image data and maintaining, where desired, the association between the bookmark 200 and the underlying source image data. The disclosed system and method act to save the bookmark by saving the succession of system inputs, which, in conjunction with the system characteristics and system parameters, achieve the desired viewing configuration. Thereby, the disclosed system and method permits review of the inputs used to manipulate the image to confirm the process by which a diagnosis or anatomical measurement was made, permits the replay of a sequence for presentation or training purposes to effectively demonstrate not only the end result, but the methodology as well.

  • Sufficiently Secure Controller Area Network
    Publication number: 20230106378
    Abstract: As automotive security concerns are rising, the Controller Area Network (CAN)—the de facto standard of in-vehicle communication protocol—has come under scrutiny due to its lack of encryption and authentication. Several vulnerabilities, such as eavesdropping, spoofing, and replay attacks, have shown that the current implementation needs to be extended. Both academic and commercial solutions for a secure CAN have been proposed, but OEMs have not yet integrated them into their products. The main reasons for this lack of adoption are their heavy use of limited computational resources in the vehicle, increased latency that can lead to missed deadlines for safety-critical messages, as well as insufficient space available in a CAN frame to include a Message Authentication Code (MAC). By making a trade-off between security and performance, this disclosure overcomes the aforementioned problems of a secure CAN.

  • Prevention of unauthorized scripts
    Patent number: 7606915
    Abstract: Methods and system of preventing unauthorized scripting. The invention includes providing one or more tests to a user for distinguishing the user from a machine when the user requests access to the server. By storing information on a correct solution to the test in a block of data and sending the block of data together with the test, the invention provides stateless operation. Moreover, maintaining a database of previously used correct responses prevents replay attacks. The invention also includes providing combinations of alternative tests, such as visually altered textual character strings, audible character strings, and computational puzzles. Other aspects of the invention are directed to computer-readable media for use with the methods and system.

  • METHOD AND APPARATUS FOR INTERCEPTION OF SYNCHRONIZATION OBJECTS IN GRAPHICS APPLICATION PROGRAMMING INTERFACES FOR FRAME DEBUGGING
    Publication number: 20170039124
    Abstract: An aspect of the present invention proposes a solution for correctly intercepting, capturing, and replaying tasks (such as functions and methods) in an interception layer operating between an application programming interface (API) and the driver of a processor by using synchronization objects such as fences. According to one or more embodiments of the present invention, the application will use what appears to the application to be a single synchronization object to signal (from a processor) and to wait (on a processor), but will actually be two separate synchronization objects in the interception layer. According to one or more embodiments, the solution proposed herein may be implemented as part of an module or tool that works as an interception layer between an application and an API exposed by a device driver of a resource, and allows for an efficient and effective approach to frame-debugging and live capture and replay of function bundles.
