JOURNAL FREE ACCESSIn this paper, we present an introduction to Distributed Hash Table (DHT) technology, an infrastructural building block for peer-to-peer style distributed systems. Distributed Hash Table can enable to perform object discovery efficiently in pure peer-to-peer distributed systems which do not have any centralized servers.View full abstractDownload PDF (364K) -

JOURNAL FREE ACCESSThis paper describes overlay networks, which is a rapidly developing methodology to construct services on top of networked computers. First, we look at the application research, the service model, and the taxonomy of algorithm research, in a top-down manner. Next, we briefly look at the architecture of structured overlay, which is a promising branch of overlay networks. Finally, we mention theories used in the overlay research, along with the tools for overlay research.View full abstractDownload PDF (104K) -

JOURNAL FREE ACCESSThis paper presents our experiences with building the Real-Time Mach operating system. Real-Time Mach is a real-time extension of the Mach operating system that has developed at Carnegie Mellon University. Real-Time Mach is large-scale software that offers binary compatibility with FreeBSD. We believe that it is useful and helpful to document our experiences for future operating system researchers.View full abstractDownload PDF (268K) -

JOURNAL FREE ACCESSWe propose a method to measure the efficiency of the information flow in a software development organization. We use a stochastic petri-net model to formalize the information flow in an organization and use the steady state analysis of a stochastic petri-net to measure the efficiency of the flow. We show that two empirical organizational patterns are validated by using our method. We also propose a method to improve the efficiency of the information flow in an organization.View full abstractDownload PDF (147K) -

JOURNAL FREE ACCESSTRMI (Transparent Remote Method Invocation) is a mechanism that allows stand-alone software systems to run in networked environments, consisting of multiple computer systems, without modifying their source code. However, stand-alone objects are not ready to be accessed simultaneously by multiple client objects. If two or more client objects on different machines access them at the same time, it will result in conflicts. TRMI allows programmers to add their own thread control mechanism to the objects without modifying their source code.View full abstractDownload PDF (327K)
