Patent number: 9929970Abstract: Described techniques enable resource accounting and tracking in high access rate systems using low cost memories. A first set of counters is maintained in relatively lower cost memory. The first counters generally indicate the amount of resources used for each object in a set of objects, but on a potentially delayed basis. A second set of counters of smaller size is stored in a relatively higher cost memory that supports high arrival and departure rates for accurate accounting. Each second counter indicates the amount of resources assigned (or unassigned) to an object since the object's first counter was last updated, and is incremented or decremented whenever this amount changes. A background process is configured to update individual first counters from the corresponding second counters on a recurring basis. The exact times at which a given first counter is updated may vary in accordance with a variety of approaches.Type: GrantFiled: December 3, 2015Date of Patent: March 27, 2018Assignee: Innovium, Inc.Inventors: William Brad Matthews, Puneet Agarwal

Patent number: 9825864Abstract: Aspects of oversubscription monitoring are described. In one embodiment, oversubscription monitoring includes accumulating an amount of data that arrives at a network component over at least one epoch of time. Further, a core processing rate at which data can be processed by the network component is calculated. Based on the amount of data and the core processing rate, it is determined whether the network component is operating in an oversubscribed region of operation. In one embodiment, when the network component is operating in the oversubscribed region of operation, certain quality of service metrics are monitored. Using the monitored metrics, a network operation display object may be generated for identifying or troubleshooting network errors during an oversubscribed region of operation of the network component.Type: GrantFiled: April 1, 2015Date of Patent: November 21, 2017Assignee: Avago Technologies General IP (Singapore) Pte.

Publication number: 20170109222Abstract: Systems and methods for predictive reliability mining are provided that enable predicting of unexpected emerging failures in future without waiting for actual failures to start occurring in significant numbers. Sets of discriminative Diagnostic Trouble Codes (DTCs) from connected machines in a population are identified before failure of the associated parts. A temporal conditional dependence model based on the temporal dependence between the failure of the parts from past failure data and the identified sets of discriminative DTCs is generated. Future failures are predicted based on the generated temporal conditional dependence and root cause analysis of the predicted future failures is performed for predictive reliability mining. The probability of failure is computed based on both occurrence and non-occurrence of DTCs. The root cause analysis enables identifying a subset of the population when an early warning is generated and also when an early warning is not generated.Type: ApplicationFiled: March 1, 2016Publication date: April 20, 2017Applicant: Tata Consultancy Services LimitedInventors: Karamjit SINGH, Gautam SHROFF, Puneet AGARWAL

Patent number: 9584426Abstract: A system forwards congestion management messages to a source host updating the source address in the management message. The system may determine that the congestion management message was triggered responsive to an initial communication that was previously forwarded by the system. The system may use header translation within a single addressing scheme and/or may translate the congestion management message into a different type to support forwarding to the source of the initial communication. The system may use portions of the payload of the congestion management message to determine the source of the initial communication and to derive a different header for the translated congestion management message.Type: GrantFiled: April 7, 2014Date of Patent: February 28, 2017Assignee: BROADCOM CORPORATIONInventors: Biju Ravindranatha Babu, Puneet Agarwal, Mohan Venkatachar Kalkunte

Publication number: 20160371376Abstract: Methods and systems for searching logical patterns in voluminous multi sensor data from the industrial internet is provided. The method retrieves instances of patterns in time-series data where patterns are specified logically, using a sequence of symbols. The logical symbols used are a subset of the qualitative abstractions specifically, the concepts of steady, increasing, decreasing. Patterns can include symbol-sequences for multiple sensors, approximate duration as well as slope values for each symbol. To facilitate efficient querying, each sensor time-series is pre-processed into a sequence of logical symbols. Each position in the resulting compressed sequence is registered across a TRIE-based index structure corresponding to the multiple logical patterns it may belong to. Logical multi-sensor patterns are efficiently retrieved and ranked using such a structure. This method of indexing and searching provides an efficient mechanism for exploratory analysis of voluminous multi-sensor data.Type: ApplicationFiled: June 17, 2016Publication date: December 22, 2016Applicant: Tata Consultancy Services LimitedInventors: Ehtesham HASSAN, Mohit Yadav, Puneet Agarwal, Gautam Shroff, Ashwin Srinivasan
