We illustrate the application of the hyperbolic model, which generalizes standard two-parameter dedicated-link models for communication costs in messagepassing environments, to four rather different distributed-memory architectures: Ethernet NOW, FDDI NOW, IBM SP2, and Intel Paragon. We first evaluate the parameters of the model from simple communication patterns. Then overall communication tim...

This paper presents a new precomputation algorithm for Multi Protocol Label Switching (MPLS) traffic engineering routing. The prior MPLS routing algorithms try to minimize the interference between different sourcedestination pairs by circumventing the critical links. But the process of identifying critical links is very computationally expensive. The main contribution of this paper is a new pre...

We present an application of multiple-objectives evolutionary optimization to the problem of engineering the distribution of the interdomain traffic in the Internet. We show that this practical problem requires such a heuristic due to the potential conflicting nature of the traffic engineering objectives. Furthermore, having to work on the parameter’s space of the real problem makes such techni...

A survey is given on two decades of developments in the field, encompassing an increase in computing power by four orders of magnitude. The '4-D approach' integrating expectation-based methods from systems dynamics and control engineering with methods from AI has allowed to create vehicles with unprecedented capabilities in the technical realm: Autonomous road vehicle guidance in public traffic...

Human computer interaction in security and time-critical systems is an interdisciplinary challenge at the seams of human factors, engineering, information systems and computer science. Application fields include control systems, critical infrastructures, vehicle and traffic management, production technology, business continuity management, medical technology, crisis management and civil protect...

Traffic engineering broadly relates to optimization of the operational performance of a network. This survey discusses techniques like multi-path routing using traffic splitting, constraint-based routing, pathprotection etc. that are used for traffic engineering. Multipath routing can be effectively used for maximum utilization of network reso urces. It gives the node a choice of next hops for ...

The accommodation of various traffic load situations in W-CDMA-based cellular systems requires the engineering of the allowed interference levels per cell. This paper presents functionality that can complement the design and management as well as the mechanisms required. The overall scheme is called Interference Level Configuration (ILC). It relies on the solution of problems, which will be con...
