System And Method For Detecting Faults In A System

View page
US Patent:
7395457, Jul 1, 2008
Filed:
Jun 10, 2005
Appl. No.:
11/149655
Inventors:
Guofei Jiang - Princeton NJ, US
Haifeng Chen - Plainsboro NJ, US
Cristian Ungureanu - Princeton NJ, US
Kenji Yoshihira - Cranford NJ, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
G06F 11/00
US Classification:
714 45
Abstract:
To determine the cause of a problem, evaluating and tracing how an individual request traverses through various components in the system makes possible new detection techniques. The present invention relates to detecting faults in a computer system. In accordance with an embodiment of the invention, a method and apparatus detects a fault in a system by receiving a request and generating a trace based on the request. The trace is a sequence of components used to service the request. The method and apparatus also compares the trace with a stored automaton to determine whether the trace is an anomaly. The stored automaton describes traces.

Automated Modeling And Tracking Of Transaction Flow Dynamics For Fault Detection In Complex Systems

View page
US Patent:
7590513, Sep 15, 2009
Filed:
Jan 30, 2006
Appl. No.:
11/275796
Inventors:
Guofei Jiang - Princeton NJ, US
Haifeng Chen - Piscataway NJ, US
Cristian Ungureanu - Princeton NJ, US
Kenji Yoshihira - Cranford NJ, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
G06F 17/10
US Classification:
703 2, 714 48
Abstract:
A method and system that automatically derives models between monitored quantities under non-faulty conditions so that subsequent faults can be detected as deviations from the derived models. The invention identifies unusual conditions for fault detection and isolation that is absent in rule-based systems.

System And Method For Content Addressable Storage

View page
US Patent:
7747663, Jun 29, 2010
Filed:
Mar 5, 2008
Appl. No.:
12/042777
Inventors:
Benjamin Atkin - New York NY, US
Grzegorz Calkowski - Hopewell NJ, US
Cristian Ungureanu - Princeton NJ, US
Cezary Dubnicki - Monmouth Junction NJ, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
G06F 17/30
US Classification:
707822, 707648
Abstract:
Information, such as files received from a client, etc. , is stored in a storage system, such as a content addressable storage system. A file server receives data from a client and chunks the data into blocks of data. The file server also generates metadata for use in forming a data structure. The blocks of data are stored in a block store and a copy of the data blocks and the metadata are locally cached at the file server. A commit server retrieves the metadata. In at least one embodiment, the metadata is retrieved from an update log shared between the file server and the commit server. Based on the retrieved metadata, the commit server generates a version of a data structure. The data structure is then stored at the block store.

Methods And Systems For Data Management Using Multiple Selection Criteria

View page
US Patent:
7844581, Nov 30, 2010
Filed:
Dec 1, 2006
Appl. No.:
11/566122
Inventors:
Cezary Dubnicki - Monmouth Junction NJ, US
Krzysztof Lichota - Warszawa, PL
Erik Kruus - Hillsborough NJ, US
Cristian Ungureanu - Princeton NJ, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
G06F 7/00
US Classification:
707693, 707698, 707821
Abstract:
Systems and methods for data management and data processing are provided. Embodiments may include systems and methods relating to fast data selection with reasonably high quality results, and may include a faster data selection function and a slower data selection function. Various embodiments may include systems and methods relating to data hashing and/or data redundancy identification and elimination for a data set or a string of data. Embodiments may include a first selection function is used to pre-select boundary points or data blocks/windows from a data set or data stream and a second selection function is used to refine the boundary points or data blocks/windows. The second selection function may be better at determining the best places for boundary points or data blocks/windows in the data set or data stream. In various embodiments, data may be processed by a first faster hash function and slower more discriminating second hash function.

Peer-To-Peer System And Method With Improved Utilization

View page
US Patent:
7870218, Jan 11, 2011
Filed:
Mar 30, 2004
Appl. No.:
10/813484
Inventors:
Cezary Dubnicki - Monmouth Junction NJ, US
Cristian Ungureanu - Princeton NJ, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
G06F 15/167
G06F 15/173
G06F 15/16
G06F 7/00
G06F 17/30
US Classification:
709213, 709226, 709232, 707622, 707620, 707831
Abstract:
The present invention is directed to improving utilization in a peer-to-peer network. Each node in a peer-to-peer network is assigned a number of preferably fixed-size storage slots proportional to the node storage, a first portion of which is allocated to storage zones and a second portion of which is allocated as a free slot reserve. In accordance with an embodiment of an aspect of the invention, this split of a storage zone is delayed until the storage zone becomes full, referred to herein as “lazy splitting”. In accordance with an embodiment of another aspect of the invention, it is advantageous to allocate more storage slots at a node than its actual physical capacity referred to herein as “oversubscription”. In accordance with an embodiment of another aspect of the invention, each physical node is allocated at least one storage zone, even as a new node is added to the system.

Scalable Secondary Storage Systems And Methods

View page
US Patent:
7992037, Aug 2, 2011
Filed:
Jul 29, 2009
Appl. No.:
12/511126
Inventors:
Cezary Dubnicki - Warsaw, PL
Cristian Ungureanu - Princeton NJ, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
G06F 11/00
US Classification:
714 62, 714 63, 714 15
Abstract:
Exemplary systems and methods in accordance with embodiments of the present invention may provide a plurality of data services by employing splittable, mergable and transferable redundant chains of data containers. The chains and containers may be automatically split and/or merged in response to changes in storage node network configurations and may be stored in erasure coded fragments distributed across different storage nodes. Data services provided in a distributed secondary storage system utilizing redundant chains of containers may include global deduplication, dynamic scalability, support for multiple redundancy classes, data location, fast reading and writing of data and rebuilding of data due to node or disk failures.

Abstract:
The present invention generally provides a method for grid storage including balancing read and write requests from applications across a first group of nodes in a grid storage system for avoiding hot spots and optimizing performance through smart caching; balancing storage capacity across a second group of nodes in the grid storage system, nodes in the first and second groups being at least one of hardware interchangeable online, capable of being added to change performance or capacity of the grid storage system and capable of being removed to change performance or capacity of the grid storage system; and self managing of the first and second groups of nodes for providing at least one of scalability, self healing after failure of components in the grid storage, non-disruptive upgrades to the grid storage system, and eliminating duplicate data on an object or sub-object level in the grid storage system.

Method For Operating A Fixed Prefix Peer To Peer Network

View page
US Patent:
8140625, Mar 20, 2012
Filed:
Jan 31, 2008
Appl. No.:
12/023141
Inventors:
Cezary Dubnicki - Monmouth Junction NJ, US
Leszek Gryz - Princeton NJ, US
Krzysztof Lichota - Warszawa, PL
Cristian Ungureanu - Princeton NJ, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
G06F 15/16
G06F 7/00
US Classification:
709205, 709206, 707E17032
Abstract:
A fixed prefix peer to peer network has a number of physical nodes. The nodes are logically divided into a number of storage slots. Blocks of data are erasure coded into original and redundant data fragments and the resultant fragments of data are stored in slots on separate physical nodes such that no physical node has more than one original and/or redundant fragment. The storage locations of all of the fragments are organized into a logical virtual node (e. g. , a supernode). Thus, the supernode and the original block of data can be recovered even if some of the physical nodes are lost.
