Patent number: 10768997Abstract: A type of a request that is currently being processed at a system is determined. A distribution is selected from a set of processing time distributions, the distribution forming a model that is applicable to the type. A threshold point is computed for the model. A processing time that exceeds a threshold point processing time is regarded as exhibiting tail latency. Tail latency includes a delay in processing of the request due to a reason other than a utilization of a resource of the system exceeding a threshold utilization and a size of a queue in the system exceeding a threshold size. An evaluation is made that the request will experience tail latency during processing at the system and the processing of the request at the system is aborted. The request is offloaded for processing at a peer system in a load-balanced group of systems.Type: GrantFiled: December 5, 2016Date of Patent: September 8, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Kanak B.

Patent number: 10491698Abstract: A dynamic data distribution system allows publication of data values for hierarchical keys (paths) and subscriptions to key (path) patterns which include wildcard characters. Permission to publish or subscribe is controlled by an access control list associated with each key. An agent receives a publication request from a client, verifies client access permissions on the subject key, and transmits the publication to a data storage server which performs the write. Following a successful write, the agent forwards the publication to a message routing exchange which routes the publication to the session queue for all clients that are permitted to receive the publication and have subscribed to a key pattern matching this publication. For data synchronization, the data storage server assigns a virtual time stamp to each write, and the subscriber verifies the count of updates received for a subscription within a sliding window of virtual time stamps.Type: GrantFiled: December 8, 2016Date of Patent: November 26, 2019Assignee: International Business Machines CorporationInventors: Kanak B.
