The present invention generally teaches systems and methods for creating appliance signatures based upon whole house composite load profiles. Methods may includes steps such as identifying primitive elements including transients and absolute steady state levels; clustering the primitive elements along multiple dimensions to form impulses; combining impulses to form simple bundles; combining simple bundles with each other or impulses to form complex bundles; and determining specific appliance signatures that substantially match the complex bundles. Methods may also include steps such as determining transitions within the whole house composite load profile; determining household specific appliance state machines for each appliance in the household; and disaggregating the whole house composite load profile into individual appliance energy loads by assigning the determined transitions to the determined household specific appliance state machines.

An application transaction (AT) server collects multiple user specified application operations for processing as a single application transaction and records essential information about each transaction being performed in a database. Such recordation enables the values of objects targeted by the particular application transaction prior to completion of a transaction to be restored in case of failed operation of the application transaction.

A computer implemented method and a computer program product includes a first computer readable code construct configured to handle request messages. This comprises receiving a request message and having an associated user name which is associated with a remote user on a network. Further, making an access determination to determine whether the forwarding of the request message is authorized, and finally when forwarding of the request message is authorized, the message to a target system is forwarded.

Method and system for allowing a computer network operations manager to subscribe for and receive notifications concerning network events from one or more objects or object levels, as defined by distinguished name scoping, and optionally having at least one event characteristic from a selected list. The selected list of characteristics may include: one or more levels of network objects involved in the event; one or more specified network nodes involved in the event; a specified geographical region in which said event occurs; a specified period of days within which the event occurs or is initiated; a specified time interval within which the event occurs or is initiated; a specified class of devices involved in the event; and an event of one or more specified event types.

Distinguished name scoping system for event filtering

A method for determining, storing, and managing names for agents and entities installed on a computer network is described. In one embodiment, a method is provided for providing a name service configured to provide unique identifiers and addresses for processes on a computer network. The name service includes a database of identifiers and addresses for the processes. A query is made to the name service that searches the database and the name service returns the answer.

Name service for network management architecture

A method for processing events generated by software and hardware entities installed on a computer network that avoids overload conditions at large event processing rates is provided. In one embodiment, the method includes the steps of providing a protocol translation facility that is configured to translate messages from a first network communications protocol to a second network communications protocol. The protocol translation facility is further configured to receive events transmitted by software and hardware entities on the network. The protocol translation facility forwards the events to a management information server. An event is received, and a determination is made whether an association between the protocol translation facility and the entity exists. The event is processed

Methods systems and software for alleviating event overload conditions for computer networks

Improved techniques for reporting events raised by entities running on computer networks are disclosed. The techniques provide an event distribution system that handles events generated by various software and other entities installed on a computer or communications network. The event distribution system is capable of handling large volumes of event traffic and can be installed and operated separately from other network management software components to provide thereby more robust operations in the case one or more components fail. In addition, the event distribution system can be scaled readily to handle greater volumes of network traffic. In one embodiment, an event distribution service is coupled with an event source. In addition, an event listener is provided on the computer network. When an event is generated from the event source and received by the event distribution system, the event distribution system processes and forwards the event, or a notification of the event, to an appropriate listener.

Apparatus, methods and computer program products are disclosed for interfacing a client based, multi-threaded API that is written in a first programming language (such as JAVA) with a server based, single-thread API that is written in a second programming language (such as C or C&plus;&plus;). The invention uses an object factory to generate a server object for each client. Programmed-method invocations performed on logical objects at the client are communicated to the server object. The server object processes the programmed-method invocation to perform the requested service such as providing network management information services.

An access control database has access control objects that collectively store information that specifies access rights by users to specified sets of the managed objects. The specified access rights include access rights to obtain management information from the network. An access control server provides users access to the managed objects in accordance with the access rights specified by the access control database. An information transfer mechanism sends management information from the network to a database management system (DBMS) for storage in a set of database tables. Each database table stores management information for a corresponding class of managed objects. An access control procedure limits access to the management information stored in the database tables using at least one permissions table. A permissions table defines a subset of rows in the database tables that are accessible to at least one of the users. The set of database table rows that are accessible corresponds to the managed object access rights specified by the access control database. A user access request to access management information in the database is intercepted, and the access control procedure is invoked when the user access request is a select statement. The database access engine accesses information in the set of database tables using the permissions tables such that each user is allowed access only to management information in the set of database tables that the user would be allowed by the access control database to access.

System and method for restricting database access to managed object information using a permissions table that specifies access rights to the managed objects

Techniques for providing a client program with remote access to information management services of a computer network are disclosed. An application programming interface can be provided to enable the client to remotely access the information management services. By using the application program interface the client can remotely invoke appropriate methods on the server to access the information management services. The application programming interface can be implemented as a thin-class. In addition, the communication between the server and the client programs is transparent to the applications that utilize the application programming interface.

Method, apparatus and program to provide client access to a management information service residing on a server in a computer network system

An access control database has access control objects that collectively store information that specifies access rights by users to specified sets of the managed objects. The specified access rights include access rights to obtain management information from the network. An access control server provides users access to the managed objects in accordance with the access rights specified by the access control database. An information transfer mechanism sends management information from the network to a database management system (DBMS) for storage in a set of database tables. Each database table stores management information for a corresponding class of managed objects. A set of views limits access to the management information stored in the database tables. Each view defines a subset of rows in the database tables that are accessible when using this view. The set of database table rows that are accessible when using each view in the set corresponds to the managed object access rights specified by the access control database for at least one the users. A view access control means specifies which views in the set of views are useable by specified ones of the users. The database access engine accesses information in the set of database tables using the set of views such that each user is allowed access only to management information in the set of database tables that the user would be allowed by the access control database to access.
