Patent number: 8676972Abstract: A method and a system for identifying unauthorized accesses to a data network service by a particular node in a data network is disclosed. The NMC communicates with an agent periodically to gather a list of users of the service node. An agent is installed on the service node to monitor all network accesses to the service. By configuring the agent to monitor all access to the service node, through SNMP or a similar protocol, the agent maintains a list of all accesses to that service node. This list is stored internally by the agent and queried for by the NMC periodically. The access information stored by the agent is periodically retrieved by the NMC for all monitored nodes and compared with the authorization list for the node. If unauthorized accesses are found, they are identified by the NMC. These unauthorized accesses can be notified to the appropriate entity in a number of ways such as through paging, email or a report viewable through the NMC.Type: GrantFiled: March 6, 2003Date of Patent: March 18, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Arvind Ramaswamy, David Schenkel, Michael Slavitch

Patent number: 7123589Abstract: Methods which determine network performance by determining not only the transit delay between nodes in a network but also the variance, or jitter, of such transit delays. A common node, usually a network management computer (NMC), sends out a signal to a first node of interest and measures the time before it receives an acknowledgment from the first node. The NMC then sends out a similar signal to a second node of interest and similarly measures the time required to receive an acknowledgment. Based on these two measurements, the transit delay between the first and second nodes can be calculated if the first node lies on the path between the NMC and the second node or vice versa. For a multiple node communications path, the total transit delay between any two nodes is the sum total of the transit delays between adjacent nodes lying on the path.Type: GrantFiled: June 23, 2000Date of Patent: October 17, 2006Assignee: Peregrine Systems, Inc.Inventors: Nicholas W. Dawes, Michael Slavitch, Arvind Ramaswamy

Publication number: 20060212559Abstract: A data source access editor and a network data management method are disclosed. The method is carried out in a network within which at least one data service element interacts with services. The network has data access layers, an administrator user interface and different platform data sources. The method includes the steps of: accepting administrator input through the user interface, processing the administrator input into executable instructions, and generating an abstraction of one of the platform data sources from the instructions. The abstraction defines a derivative of the one of the platform data sources that the data service element makes available to the services. The abstraction coordinates the data service element in effectuating operations on the one of the platform data sources, such that the operations generate data source responses communicated to the services in order for the services to be performed.Type: ApplicationFiled: March 2, 2005Publication date: September 21, 2006Applicant: Objectworld Communications Corp.Inventors: Christopher James Turnbull, Jeffrey Wissing, Michael Slavitch, Robert Turner

Publication number: 20050149617Abstract: Graphical interface based software for creating communication service agents is disclosed. The software is stored on or embodied in a computer readable medium used in a computer system having at least one display device, at least one input device operated by a computer user and at least one storage device having structured data. The computer readable medium includes code executable in the system to provide a service editor for use by the computer user. The service editor is for creating at least one interactive service and has a graphical user interface (GUI). The GUI permits the computer user to build a flow map defining the interactive service. The flow map is displayable on the display device and includes a plurality of elements connected together by flow lines. At least one of the elements incorporates a customizer for assisting the computer user in further defining the interactive service. Operations on the structured data are effectuated by the interactive service.Type: ApplicationFiled: March 2, 2005Publication date: July 7, 2005Applicant: Objectworld Communications Corp.Inventors: Christopher Turnbull, Jeffrey Wissing, Michael Slavitch, Robert Turner
