Dynamic reconfiguration of hub-based networks
Proceedings of 1993 IEEE 1st International Workshop on Systems Management, 2002The flexibility that an intelligent hub adds to the planning, configuration, and management of a network of local area networks is discussed. We specifically address the capability to improve the performance of the overall system by flexing dynamically the boundaries of the constituent networks of a hub-based network according to traffic and quality of

Dynamic reconfiguration policies for WDM networks
IEEE INFOCOM '99. Conference on Computer Communications. Proceedings. Eighteenth Annual Joint Conference of the IEEE Computer and Communications Societies. The Future is Now (Cat. No.99CH36320), 1999We study the issues arising when considering the problem of reconfiguring broadcast optical networks in response to changes in the traffic patterns. Although the ability to dynamically optimize the network under changing traffic conditions has been recognized as one of the key features of multiwavelength optical networks, this is the first in-depth ...

Dynamic Reconfiguration in Multihop WDM Networks
Journal of High Speed Networks, 1995We consider multichannel multihop lightwave networks with stations equipped with a small number of transmitters and receivers. By assigning wavelengths to the receivers and transmitters at each station, one can define the logical connectivity of the network independently of the underlying physical topology.

Ordinal Optimization for Dynamic Network Reconfiguration
Electric Power Components and Systems, 2011Abstract Motivated by the challenge of efficiently reconfiguring distribution networks for power loss reduction, this study presents an approach for finding a minimum loss radial configuration for a power network using ordinal optimization. Ordinal optimization relies on order comparison and goal softening to make the problem solution easier and the ...

Information Stream Based Network Dynamic Reconfiguration
2007 IEEE International Conference on Networking, Sensing and Control, 2007In order to improve the security, reliability and performance of the existing network reconfiguration, this paper proposes a dynamic reconfiguration method based on information stream, which can guarantee not only the arrival of the important information to the destination, but also the network performance by different information streams go through ...

Fast dynamic reconfiguration in irregular networks
Proceedings 2000 International Conference on Parallel Processing, 2002Exploitation of the wiring flexibility in Networks of Workstations demands configuration methods that can handle dynamic changes in irregular topologies. During reconfiguration of a network based on virtual cut-through or wormhole switching, however deadlocks in the transition phase between the old and the new routing function must be avoided.

DRAFT: Flexible interconnection network for dynamically reconfigurable architectures
2009 International Conference on Field-Programmable Technology, 2009Dynamic and partial reconfiguration allows to place on line the various tasks that describe an application, in available regions of an FPGA. This new featur leads notably to communication problems since tasks are not present in the matrix during all computation time. In this article, we compare popular interconnection architectures.

Evolving Dynamically Reconfiguring UAV-hosted Mesh Networks
2020 IEEE Congress on Evolutionary Computation (CEC), 2020We use potential fields tuned by genetic algorithms to dynamically reconFigure unmanned aerial vehicles networks to serve user bandwidth needs. Such flying network base stations have applications in the many domains needing quick temporary networked communications capabilities such as search and rescue in remote areas and security and defense in ...

Epoch-based reconfiguration: Fast, simple, and effective dynamic network reconfiguration
2008 IEEE International Symposium on Parallel and Distributed Processing, 2008Dynamic network reconfiguration is defined as the process of changing from one routing function to another while the network remains up and running. The main challenge is to avoid deadlocks and reduce packet dropping rate while keeping network service. Current approaches either require the existence of extra network resources like e.g. virtual channels,

Bayesian-Based Virtual Network Reconfiguration for Dynamic Optical Networks
Journal of Optical Communications and Networking, 2018Network virtualization is a key technology for accommodating varying traffic demands on optical networks. Network operators construct a virtual network (VN) by slicing physical resources, and resolve traffic congestion by reconfiguring the VN in response to traffic changes.
