A method for metering on-demand service (ODS) resource consumption by a user comprising a web services interface, a processing engine, and configuration data. A data gathering agent in the ODS stores the usage data in records, combines the records into packets, and transmits the packets to the web services interface. The web services interface passes the packets onto the processing engine, which stores the records in the packet into a database. The generalized format of the record is critical because it allows the metrics to be stored in the record table with the usage data. When a record contains an instruction to close a UOW, the processing engine applies the configuration data comprising composition rules and record selection rules to the database. The record selection rules select the desired records from the database. The composition rules aggregate, normalize, and compose the selected records to produce a metric.

System for metering in an on-demand utility environment

An infrastructure for on-demand service delivery receiving a request for a service to be performed from a service consumer with an information payload; decomposing requested service into essential or primitive functions; dynamically composing a sequence of a plurality of service elements corresponding to the essential or primitive functions to accomplish the service by employing a function call and return decomposition and recomposition paradigm; creating a control header and information payload, the control header encapsulating the sequence; repeatedly dispatching the control header to each service element in the sequence until all service elements have processed the information payload; and returning the processed information payload to the service consumer.

Dynamic service-on-demand delivery messaging hub

A method and implementing computer system are provided in which a unique primary key is generated to identify an original message which is received for processing. The record for the original message is stored at the primary key. As the message is propagated to the services that are to be performed on the original message, the primary key is also passed to the service. Derivative messages which are produced as a result of the services applied to the original message are identified with the primary key code along with additional derivative key codes related to services applied to the original message. The resulting derivative message storing and tracking process provides a means by which derivative messages are readily identified and associated with an original message as well as the services performed upon the original message in generating the derivative message.

A system and method for binding processes in an e-commerce HUB are present. The e-commerce HUB manages transaction processes between trading partners by tracking document exchange instances and translating documents and business processes as needed. The e-commerce HUB supports multiple connection methods and provides an open forum for small businesses to become trading partners with large businesses without supporting multiple business processes. The e-commerce HUB may allow or restrict e-commerce transactions with other members based on permissions associated with member profiles.

A system and method for partial ordering service capabilities in an e-marketplace hub is presented. A recipient trading partner sets receive message constraints and a sending trading partner specifies sending message capabilities. The e-marketplace hub compares the receive message constraints with the sending message capabilities. If the sending message capabilities are a subset of the receive message constraints, the e-marketplace hub establishes a trading partner link between the sending trading partner and the recipient trading partner so the sending trading partner may send messages to the recipient trading partner. The e-marketplace hub may recursively compare sending message capabilities with receive message constraints at various levels to ensure a valid trading partner link.

Mutual authentication between a client and server over the Internet utilizing the IOP protocol in its current state is enabled by first engaging in a 'dummy' request when a client initiates a request to a new target server for the first time. This provides the means for creating a two way authentication mechanism. Rather than creating an object reference for the dummy request, the object reference at hand in the client, which the client is about to utilize for a request, is reused by extracting a proxy object from the request. The request is intercepted in the client and the proxy object passed to the interception method. The client next issues a two-way remote method already defined for the proxy object, such as the 'non_existent( )' method defined on the CORBA object. The client then computes a security token, and sends the dummy request to the server. The server intercepts the dummy request, validates the security token received in the dummy request, and acquires a new authentication token to be returned to the client. Upon interception of the outgoing message, the new security token is marshalled in the security service context and sent to the client on the response message. The client intercepts the reply message and demarshals the security service context to recover the security token and complete mutual authentication.

A method and apparatus in a computer system for establishing a connection between a client proxy object and a server target object. A request is received from the client proxy object to access the server target object, wherein the request includes an identification of a type of communication and type of message to be sent to the server target object. A connection object is identified based on the type of communication and the type of message. The connection object implementing the type of communication is returned, wherein the connection between the client proxy object and the server target object is facilitated using the connection object.

A method is provided for initializing and updating a group of pixels contained on a display in blocks. A group of pixels is considered as a block and has a status word associated therewith. This status word maintains a running total of the maximum z value of any pixel contained within a group, or block of pixels. In this manner, once a block of pixels is rendered on to the display screen a comparison can be made between the current pixels being displayed and a group of pixels which are to be displayed. The minimum z value of the group of pixels to be displayed is compared with the maximum z value for the group of pixels currently being displayed. If the current maximum z value, as stored in the status word, is less than the minimum z value for the pixels to be displayed, then the group of pixels currently being displayed will all 'win' when compared to the pixels in the group to be displayed. Thus, a full block bypass of the group of pixels to be displayed is implemented, thereby saving considerable time and overhead when compared to conventional z buffer systems that compare z values for each individual pixel.

A method for managing a data transfer between a first device and an allocated portion of common memory including the steps of receiving a reallocation request of the allocated portion of common memory from a second device, receiving a veto of the requested reallocation from the first device, and delaying the reallocation request. In addition, a method for transferring data between a peripheral device and a common memory in a virtual memory system including the steps of instructing the peripheral device to transfer data with an allocated portion of the common memory, requesting a reallocation of the allocated portion of the common memory, and receiving a veto of the requested reallocation from the peripheral device in response to the instructed data transfer. Furthermore, an apparatus for transferring data between a peripheral device and a common memory in a virtual memory system including an apparatus for instructing the peripheral device to transfer data with an allocated portion of the common memory, an apparatus for requesting a reallocation of the allocated portion of the common memory, and an apparatus for receiving a veto of the requested reallocation from the peripheral device in response to the instructed data transfer.

A method and apparatus is provided which allows a computer graphics system to accurately determine the actual depth value for pixels on a display screen which lie at the same depth as an associated surface. The associated surface is identified such that the delta z value with respect to the x and y direction along the surface can be calculated. The present invention then determines whether the line being considered is contained within a surface, or is an edge lying between, and adjacent to two surfaces. If the line is contained within a surface, the delta z value is initially added to the known endpoints of the line and then successively added, in the incremental x or y directions, to the pixels selected to represent the line. If the line is an edge, and includes selected pixels which lie on both associated surfaces, a filter is invoked that prevents those pixels corresponding to the surface, other than the surface first being considered, from being processed. The pixels being considered are then drawn in the same manner as a line within a surface. In this manner, the actual z value for each selected pixel can be determined and any hidden line, hidden surface removal problems are eliminated.
