Scalable Load-Adaptive Web-Based Network Management System： An Architectural Prototype

With the advances in enterprise communication and web technologies, web has evolved into a platform for delivering interactive applications. Web-based applications are revolutionizing both the features that can be delivered and the technologies for developing and deploying applications. In this paper, we present a web-based load-adaptive network management system framework. Our system is scalable, extendable, modular and based on open architecture. It is also load-adaptive as it can adapt to the increase in the number of incoming Web Service requests so that the systems performance will not degrade under heavy request loads. To evaluate the proposed architecture, we built a multi-tiered web application testbed with open-source components widely used in industry. Experimental studies conducted on the testbed demonstrated the effectiveness of the proposed approach. By developing the platform and making it available to the research community, we hope to catalyze the development of an open source stack for Web-based network management and monitoring.

Investigating Road Safety Management Systems in the European Countries: Patterns and Particularities

A road safety management (RSM) system can be defined as “a complex institutional structure that involves cooperating and interacting bodies which support the tasks and processes necessary for the prevention and reduction of road traffic injuries”. RSM should promote the road safety progress of the country. However, the details of this relationship are generally lacking. This study explored the RSM systems in European countries based on the information collected through interviews with experts and officials, in each country, and using a “good practice” criteria questionnaire. The dataset included 14 countries with fifty items related to five RSM areas: institutional organization;policy formulation and adoption;policy implementation and funding;monitoring and evaluation;scientific support, information and capacity building. Cluster analyses and correlations were used to identify country groups with similar RSM components, to recognize typical RSM structures if available and to examine the relationship between RSM and road safety performance of the countries. The findings showed that all the countries are different when RSM systems are considered as a whole, making it impossible to identify typical RSM structures or a single best working model at a national level. However, it is possible to compare countries when the RSM areas are considered separately, where the clusters of countries recognized by the study present the patterns common for those European countries. Across the analyses, a number of countries with a consistently higher and lower availability of the RSM components were identified, enabling a final countries’ ranking into a number of groups. The latter actually reflects the level of RSM in the country, in terms of its correspondence to the “good practice” criteria. A further analysis indicated a positive correlation between the higher level of the RSM system and better safety performance of the countries.

Research and Design of IPv6 Network Management and Operations Support System

IPv6 is the foundation of the development of Next Generation Internet (NGI). An IPv6 network management and operations support system is necessary for real operable NGI. Presently there are no approved standards yet and relevant equipment interfaces are not perfect. A Network Management System (NMS) at the network layer helps implement the integrated management of a network with equipment from multiple vendors, including the network resources and topology, end-to-end network performance, network failures and customer Service Level Agreement (SLA) management. Though the NMS will finally realize pure IPv6 network management, it must be accommodated to the management of relevant IPv4 equipment. Therefore, modularized and layered structure is adopted for the NMS in order to implement its smooth transition.

Stochastic Design of Enhanced Network Management Architecture and Algorithmic Implementations

The paper is focused on available server management in Internet connected network environments. The local backup servers are hooked up by LAN and replace broken main server immediately and several different types of backup servers are also considered. The remote backup servers are hooked up by VPN (Virtual Private Network) with high-speed optical network. A Virtual Private Network (VPN) is a way to use a public network infrastructure and hooks up long-distance servers within a single network infrastructure. The remote backup servers also replace broken main severs immediately under the different conditions with local backups. When the system performs a mandatory routine maintenance of main and local backup servers, auxiliary servers from other location are being used for backups during idle periods. Analytically tractable results are obtained by using several mathematical techniques and the results are demonstrated in the framework of optimized networked server allocation problems. The operational workflow give the guidelines for the actual implementations.

An Emulating Environment for Network Management of Space Network

Effect of Intention on Outcome Bias in Decision Making—Implications for Safety Management

The evidence of outcome bias was explored in a two-player (Player 1: allocator and Player 2: evaluator) economic game experiment where the reward allocation was made between two players. The experimental factors were the intention of an allocator (Player 1), the type of chosen dice (selfish, fair, and generous), and the outcome (selfish, fair, and generous). The outcome bias occurred when the type of dice chosen by the allocator (Player 1) was not only a selfish one but also a generous one. The comparison between the two conditions (intentional and no-intentional conditions) definitely showed that Player 2 punished Player 1 to a larger extent when the outcome was disadvantageous for Player 2 (selfish outcome) and Player 2 rewarded Player 1 when the outcome was advantageous (generous outcome) irrespective of whether the die was chosen out of the three types intentionally or not. Moreover, the outcome bias was not observed when the outcome was fair. Thus, we could verify the hypothesis that we are readily got trapped in the outcome bias. Some implications were given for safety management that put more emphasis on the process than on the outcome.
