In both e-business and e-science, we often need to integrate services across distributed, heterogeneous, dynamic “virtual organizations” formed from the disparate resources within a single enterprise and/or from external resource sharing and service provider relationships. This integration can be technically challenging because of the need to achieve various qualities of service when running on top of different native platforms. We present an Open Grid Services Architecture that addresses these challenges. Building on concepts and technologies from the Grid and Web services communities, this architecture defines a uniform exposed service semantics (the Grid service); defines standard mechanisms for creating, naming, and discovering transient Grid service instances; provides location transparency and multiple protocol bindings for service instances; and supports integration with underlying native platform facilities. The Open Grid Services Architecture also defines, in terms of Web Services Description Language (WSDL) interfaces and associated conventions, mechanisms required for creating and composing sophisticated distributed systems, including lifetime management, change management, and notification. Service bindings can support reliable invocation, authentication, authorization, and delegation, if required. Our presentation complements an earlier foundational article, “The Anatomy of the Grid,” by describing how Grid mechanisms can implement a service-oriented architecture, explaining how Grid functionality can be incorporated into a Web services framework, and illustrating how our architecture can be applied within commercial computing as a basis for distributed system integration—within and across organizational domains.

The Physiology of the Grid An Open Grid Services Architecture for Distributed Systems Integration

Methods and systems consistent with the present invention provide a data processing system having a business object model reflecting the data used during a business transaction. Consistent interfaces are generated from the business object model. These interfaces are suitable for use across industries, across businesses, and across different departments within a business during a business transaction.

A flow processing facility, which uses a set of artificial neurons for pattern recognition, such as a self-organizing map, in order to provide security and protection to a computer or computer system supports unified threat management based at least in part on patterns relevant to a variety of types of threats that relate to computer systems, including computer networks. Flow processing for switching, security, and other network applications, including a facility that processes a data flow to address patterns relevant to a variety of conditions are directed at internal network security, virtualization, and web connection security. A flow processing facility for inspecting payloads of network traffic packets detects security threats and intrusions across accessible layers of the IP-stack by applying content matching and behavioral anomaly detection techniques based on regular expression matching and self-organizing maps. Exposing threats and intrusions within packet payload at or near real-time rates enhances network security from both external and internal sources while ensuring security policy is rigorously applied to data and system resources. Intrusion Detection and Protection (IDP) is provided by a flow processing facility that processes a data flow to address patterns relevant to a variety of types of network and data integrity threats that relate to computer systems, including computer networks.

This paper presents a framework for exploring issues in time-dependent planning: planning in which the time available to respond to predicted events varies, and the decision making required to formulate effective responses is complex. Our analysis of time-dependent planning suggests an approach based on a class of algorithms that we call anytime algorithms. Anytime algorithms can be interrupted at any point during computation to return a result whose utility is a function of computation time. We explore methods for solving time-dependent planning problems based on the properties of anytime algorithms.

A resource allocation manager and technique for servers within a computer system. Resources are initially allocated to servers and in order to enhance system performance, resources are reallocated based on a minimization of the maximum performance index. In one example, the server with the largest performance index is allocated additional resources and the server with the smallest performance index loses some of its resources.

The emerging paradigm of Web services opens a new way of Web application design and development to quickly develop and deploy Web applications by integrating independently published Web services components to conduct new business transactions. As research aiming at facilitating Web services integration and verification, WS-Net is an executable architectural description language incorporating the semantics of colored Petri-net with the style and understandability of object-oriented concepts. WS-Net describes each Web services component in three layers: interface net declares the services that the component provides to other components; interconnection net specifies the services that the component acquires to accomplish its mission; and interoperation net describes the internal operational behaviors of the component. As an architectural model that formalizes the architectural topology and behaviors of each Web services component as well as the entire system, WS-Net facilitates the verification and monitoring of Web services integration.

A method (and structure) of querying one or more Web-based data sources, includes receiving a query statement including at least one query, parsing the input query to identify a target data source for each query, and dispatching each query to a respective one of the data sources for a target data source search.

This paper describes a clustered multiprocessor system developed for the general-purpose, large-scale commercial marketplace. The system (S/390e Parallel Sysplex™) is based on an architecture designed to combine the benefits of full data sharing and parallel processing in a highly scalable clustered computing environment. The Parallel Sysplex offers significant advantages in the areas of cost, performance range, and availability.

Process-based composition of Web services has recently gained significant momentum in the implementation of business processes. A critical and time-consuming part of business process development is the detection and handling of exceptions that may occur during process execution. In this paper, we introduce a novel, policy-driven approach to exception management, which substantially simplifies business process development. We advocate that exception management should be implemented in the system infrastructure. Using our exception management framework, developers define exception policies in a declarative manner. Before a business process is executed, the service composition middleware integrates the exception policies with normal business logic to generate an exception-aware process schema. We argue that our policy-driven approach significantly reduces the development time of business processes through its separation of the development of the business logic and the exception handling policies.
