- Innovative Software Architecture (Part II)
- The purpose of information technology is to establish new business processes. By separating concerns, one can focus on the business functionality which is the true purpose of the information system. Ideally, architects would like to separate the distributed system issues into categories of design where the majority of components are...

- High Fidelity Denial of Service (DoS) Experimentation
- Experimentation with security attacks introduces additional requirements compared to traditional networking and distributed system experiments. High capacity attack flows can push systems beyond their expected operational regions, and expose unexpected behaviors. Many popular simulation and emulation environments fail to account for such behaviors, and incorrect results have been reported based...

- Troubleshooting Distributed Systems Via Data Mining
- Through massive parallelism, distributed systems enable the multiplication of productivity. Unfortunately, increasing the scale of available machines to users will also multiply debugging when failure occurs. Data mining allows the extraction of patterns within large amounts of data and therefore forms the foundation for a useful method of debugging, particularly...

- Model Driven Security Management: Making Security Management Manageable in Complex Distributed Systems
- Today, the challenge in security of complex distributed systems does not anymore lie in encryption or access control of a single middleware platform, but in the protection of the system as a whole. This includes the definition of correct security policies at various abstraction layers, and also in the unified...

- Using Real Options to Select Stable Middleware - Induced Software Architectures
- The requirements that force decisions towards building distributed system architectures are usually of non-functional nature. Scalability, openness, heterogeneity, and fault-tolerance are examples of such non-functional requirements. The current trend is to build distributed systems with middleware, which provide the application developer with primitives for managing the complexity of distribution, system...

- Selective Alerts for Runtime Protection of Distributed Systems
- Network Intrusion Detection Systems NIDS are popular components for a fast detection of network attacks and intrusions, but their efficacy is limited by the high numbers of false alarms that affect them. As a consequence, system administrators, that have to manually manage an overwhelming amount of intrusion alerts, tend to...

- Hierarchical Load Balancing in Large Distributed Systems
- This paper describes a hierarchical load balancing system intended for use within large cluster computing systems. The load balancing algorithm is able to deal with situations where the tasks have different requirements with respect to CPU time and other resources, and the available computers are correspondingly able to offer different...

- Adapting the Web Interface: An Adaptive Web Browser
- The growing number of mobile computing devices with diverse characteristics creates a requirement for seamless device independent access to computing resources of distributed systems. One of the most common applications in distributed systems is the Web browser, which is not only used to access resources on the Internet but also...

- An XML-Based Protocol for Distributed Event Services
- A recent trend in distributed computing is the construction of high-performance distributed systems called computational grids. One difficulty they have encountered is that there is no standard format for the representation of performance information and no standard protocol for transmitting this information. This limits the types of performance analysis that...

- Buffered Coscheduling: A New Methodology for Multitasking Parallel Jobs on Distributed Systems
- Buffered coscheduling is a scheduling methodology for time-sharing communicating processes in parallel and distributed systems. The methodology has two primary features: communication buffering and strobing. With communication buffering, communication generated by each processor is buffered and performed at the end of regular intervals to amortize communication and scheduling overhead. This...

- Sinfonia: A New Paradigm for Building Scalable Distributed Systems
- This paper proposes a new paradigm for building scalable distributed systems. One's approach does not require dealing with message-passing protocols - a major complication in existing distributed systems. Instead, developers just design and manipulate data structures within the service called Sinfonia. Sinfonia keeps data for applications on a set of...

- A Truthful Mechanism for Fair Load Balancing in Distributed Systems
- This paper considers the problem of designing load balancing protocols in distributed systems where the participants (e.g. computers, users) are capable of manipulating the load allocation algorithm in their own interest. Using techniques from mechanism design theory a mechanism for fair load balancing is designed in heterogeneous distributed systems. It...

- Multiple Ant Colonies Optimization for Load Balancing in Distributed Systems
- Ant Colony Optimization ACO has proved its success as a meta-heuristic optimization in several network applications such as routing and load balancing. In this paper, a proposed ACO algorithm for load balancing in distributed systems will be presented. This algorithm is fully distributed in which information is dynamically updated at...

- Optimizing Across Interfaces
- Programmers writing distributed systems are poorly served by current optimization technologies. Although there are well-known ways to improve performance - batching requests, caching results, speculation and so on - these must be applied manually, adding to the burden already faced when writing distributed systems. In this paper it is argued...

- Real-Time End-to-End Network Monitoring in Large Distributed Systems
- Measuring real-time end-to-end network path performance metrics is important for several distributed applications such as media streaming systems (e.g., for switching to paths with higher bandwidth and lower jitter) and content distribution systems (e.g., for selecting servers with lower latency). However, it is challenging to perform such end-to-end pairwise measurements...

- Building Scalable, High Performance Cluster and Grid Networks: The Role of Ethernet
- A Grid computer is a hardware and software system that integrates a collection of distributed system components (e.g., computer systems, storage, etc.) making them appear to the user as a single, large "virtualized" computing system. The basic "single system" concept may be applied to the construction of centralized "cluster" computers...

- A Service Oriented Architecture Supporting Data Interoperability for Payments Card Processing Systems
- As the size of an organization grows, so does the tension between a centralized system for the management of data, metadata, derived data, and business intelligence and a distributed system. With a centralized system, it is easier to maintain the consistency, accuracy, and timeliness of data. On the other hand...
