Large water distribution systems can be highly vulnerable to penetration of contaminant factors caused by different means including deliberate contamination injections. As contaminants quickly spread into a water distribution network, rapid characterization of the pollution source has a high measure of importance for early warning assessment and disaster management. In this paper, a methodology...

A wide range of security services may be available to applications in a heterogeneous computer network environment. Resource Management Systems (RMSs) responsible for assigning computing and network resources to tasks need to know the resource-utilization costs associated with the various network security services. In order to understand the range of security services an RMS needs to manage , a...

To process large volumes of computer data such as computer animation production, many animators and directors need a high performance digital work environment. For example, a substantial infrastructure consisting of a broadband network and high performance computer systems to work in collaboration flexibly. Animators in the MMTC can do efficient animation painting work while having secure commu...

This work describes the effort to join two different approaches about the development of the Proactive Network Management. The first approach was developed in the Laboratory of Network and Management, at Federal University of Santa Catarina [2][3][4], which uses remote monitoring and simulation tools. And the second one, was developed in the National Supercomputing Center [9][10], which handles...

With their increased power and versatility, today’s computer networks are becoming used for an ever-growing number of diverse applications. Further, the networking structures are now very complex and diverse. With this growth comes the requirement for a highlevel of service and performance. It is essential to be able to offer an integrated management infrastructure, which encompasses a range of...

By interconnecting high-volume, standard computers, system architects can construct a high-performance, modular, parallel system, called a cluster,1,2 at a much lower cost than a specialized system. In addition, with a standard operating system running on each computer, or node, a cluster can cleanly survive the failure of an individual computer, disk, network, or other subsystem. A cluster can...

Large, heterogeneous computer and telecommunication networks with ever changing topology and size are typical environments todays network management (NM) systems struggle to control. Unexpected events occur frequently in these complex networks, and many of the events result in failure situations where the NM system is required to intervene and restabilize the network. By distributing the NM sys...

ANCORS is a distributed tool suite that merges technology from network management , active networking, and distributed simulation in a uniied paradigm to assist in the assessment, control, and design of computer networks. This paper explores some of the advantages that can be obtained from merging the three technologies, and describes how ANCORS integrates complementary elements of each. ANCORS...
