An open architecture for secure interworking services
Authors: Richard Hayton, Ken Moody
Venue: Proceedings of the 7th workshop on ACM SIGOPS European workshop: Systems support for worldwide applications (1996)

There is a developing need for applications and distributed services to cooperate or inter-operate. Current mechanisms can hide the heterogeneity of host operating systems and abstract the issues of distribution and object location. However, in order for systems to inter-operate securelythere must also be ways to hide differences in security policies, or at least to support negotiation between them.Other proposals for the interworking of security mechanisms have focussed on the enforcement of access policy at the expense of flexibility of expression of policy. This work describes a new architectural approach to security. The key idea is that a processis the universal client entity; a process may act on behalf of an identified individual as in traditional security schemes. More generally, a process may adopt an application-specific name or role, and this is used as the basis for authentication in Oasis. A service may then be written in terms of service-specific categories of clients, decoupled from the mechanisms used to specify and enforce access control policy.This approach allows great flexibility when integrating a number of services, and reduces the mismatch of policies that is common in heterogeneous systems. In addition, Oasis services may be integrated with alternative authentication and access control schemes, providing a truly open architecture.A flexible security definition is meaningless if not backed by a robust and efficient implementation. Oasis has been fully implemented, and is inherently distributed and scalable. In this paper we describe the general approach then concentrate on revocation, where security designs are most often criticised. Oasis is unique in supporting the rapid and selective revocation of privileges which can cascade between services and organisations.
Agent-based mobility add-in feature for Object Transaction Service (OTS)
Authors: Hoang Pham Huy, Simone Sedillot
Venue: Proceedings of the 2002 ACM symposium on Applied computing (2002)

Service session mobility is a new concept in the next telecom service generation. It allows users to move from one terminal in one network to another terminal in another network with service continuity. This concept requires migrating the current service execution related information, including service context, service data, etc, from one terminal to another. For services that execute within transactions, transaction context is a part of service context and must be migrated too. This paper presents our work on this problem, based on CORBA Object Transaction Service. Mobile agent is the enabling technology, which enhances the transaction service with mobility features.This model was initially designed for VHE architecture of VESPER, a European project to design a model for Virtual Home Environment in the next generation of telecom network. However, it can be applied to any other architecture, which require to solve the problem of service session mobility with transaction.

Design and implementation of a QoS oriented data-link control protocol for CBR traffic in wireless ATM networks
Authors: H. Kim, S. K. Biswas, P. Narasimhan, R. Siracusa, C. Johnston
Venue: Wireless Networks (2001)

This paper presents a QoS oriented Data Link Control (DLC) framework for transporting Constant Bit Rate (CBR) traffic over wireless ATM links. Data link control is usually omitted in fixed ATM networks because cell corruption due to channel error is extremely rare for reliable media like copper wire and optical fiber. However, for wireless, higher bit error rates are quite common due to shadowing and other fading effects. The purpose of DLC in wireless is to provide error-free transport to the higher layers by recovering corrupted cells at the link layer. A selective reject (SREJ) automatic repeat request (ARQ) based DLC protocol is used for CBR error recovery. For an ARQ based scheme, higher recovery rates can be achieved with larger cell transfer delay, caused by cell retransmissions. Since cell transfer delay and DLC recovery rate both translate to user-perceivable Quality-of-Service (QoS), it is important for the DLC to strike a balance between these two, depending on the application's requirements. To achieve this in our protocol, the retransmission procedure for a CBR cell is constrained to complete within a recovery time interval which is specified by the application at call-setup time. Also, a novel jitter removal scheme that reduces the cell delay variation caused by cell loss and retransmissions, is incorporated as a part of the DLC protocol. The proposed protocol is implemented on NEC's WATMnet prototype system. The implementation and its experimental results are reported for illustrating the performance and feasibility of the presented CBR DLC protocol. The experimental results show that the DLC protocol can be successfully applied for QoS-constrained error recovery of CBR traffic on a per-connection basis. These also indicate that the DLC can be programmed to attain a desirable tradeoff between cell transfer delay and cell recovery rate.
An infinite hierarchy of temporal logics over branching time
Authors: Alexander Rabinovich, Shahar Maoz
Venue: Information and Computation (2002)

Many temporal logics have been suggested as branching time specification formalisms during the past 20 years. These logics were compared against each other for their expressive power, model checking complexity, and succinctness. Yet, unlike the case for linear time logics, no canonical temporal logic of branching time was agreed upon. We offer an explanation for the multiplicity of temporal logics over branching time and provide an objective quantified yardstick to measure these logics. We define an infinite hierarchy BTLk of temporal logics and prove its strictness. We examine the expressive power of commonly used branching time temporal logics. We show that CTL* has no finite base, and that almost all of its many sublogics suggested in the literature are inside the second level of our hierarchy. We introduce new Ehrenfeucht-Fraiss&eacute; games on trees and use them as our main tool to prove inexpressibility. 2001 Elsevier Science

A New Adaptive Hardware Tree-Based Multicast Routing in K-Ary N-Cubes
Authors: Dianne R. Kumar, Walid A. Najjar, Pradip K. Srimani
Venue: IEEE Transactions on Computers (2001)

Multicast communication is a key issue in almost all applications that run on any parallel architecture and, hence, efficient implementation of of multicast is critical to the performance of multiprocessor machines. Multicast is implemented in parallel architectures either via software or via hardware. Software-based approaches for implementing multicast can result in high message latencies, while hardware-based schemes can greatly improve performance. Deadlock freedom in multicast communication is much more difficult to achieve resulting in more involved routing algorithms and higher startup delays. Hardware tree-based algorithms do not require these high startup delays, but do suffer from high probabilities of message blocking leading to poor performance. In this paper, we propose a new hardware tree-based routing algorithm (HTA) for multicast communication under virtual cut-through switching in k-ary n-cubes that outperforms existing software and hardware path-based multicast routing schemes. Simulation results are compared against several commonly used multicast routing algorithms and show that HTA performs extremely well under many different conditions.

Visualization of large web access data sets
Authors: Ming C. Hao, Pankaj Garg, Umeshwar Dayal, Vijay Machiraju, Daniel Cotting
Venue: Proceedings of the symposium on Data Visualisation 2002 (2002)

Many real-world e-service applications require analyzing large volumes of transaction data to extract web access information. This paper describes Web Access Visualization (WAV) a system that visually associates the affinities and relationships of clients and URLs for large volumes of web transaction data. To date, many practical research projects have shown the usefulness of a physics-based mass-spring technique to layout data items with close relationships onto a graph. The WAV system: (1) maps transaction data items (clients, URLs) and their relationships to vertices, edges, and positions on a 3D spherical surface; (2) encapsulates a physics-based engine in a visual data analysis platform; and (3) employs various content sensitive visual techniques - linked multiple views, layered drill-down, and fade in/out - for interactive data analysis. We have applied this system to a web application to analyze web access patterns and trends. The web service quality has been greatly benefited from using the information provided by WAV.

Control and Instrumentation Technology in HVAC: PCs and Environmental Control
Authors: Michael F. Hordeski
Venue:  (1999)

:While most industrial controls have benefitted from advances in personal computer control and sensor technology, building controls have lagged behind. Only now are some of the techniques used in industrial automation showing up in HVAC. As energy costs continue to grow in relation to overall operating costs, the need for more refined HVAC control becomes more crucial. HVAC strategies, such as optimizing start-up time and supply air temperature, and minimizing fan energy and reheating, are not only possible but are becoming necessary. This book examines the relationship between industrial automation techniques and evolving HVAC systems, and how emerging technologies can now be applied to HVAC systems. Topics covered include optimizing HVAC, boiler and pump control, heat pump and chiller optimization, environmental controls, wireless control, computer control, and building automation.
Variations on the binary buddy system for dynamic memory management
Authors: Arie Kaufman
Venue: Proceedings of the 18th annual Southeast regional conference (1980)

Two new variations of the binary buddy system for dynamic storage bookkeeping are introduced. These variations, the revised buddy system and the tailored-lists buddy system, recombine smaller memory blocks only upon necessity in an attempt to save on processor execution time. Simulation results comparing the three systems reveal that the two new variations are superior to the original buddy system, since they are faster and the difference in memory utilization is insignificant. A comparison of the revised system and the tailored-lists system indicates that they are equal in performance.
