In interconnection networks, reconfiguration protocol is necessary to remap and reconnect the network paths, so that the network remains connected. However, the reconfiguration process brings the deadlock problem and prevention of deadlock is a tedious task in this situation. In existing works, very little work have considered deadlock problem and further, they paid no attention to reduce packe...

— To prevent from topology changes, failures, or overloads, network management requires frequently computation and reconfiguration of established connections. When the number of established connections in the network is very large, the optimization of the reconfiguration task is essential to have short latency. When the communications using these connections are real-time, traffic interruption ...

Individually Network reconfiguration or Capacitor control perform well in minimizing power loss and improving voltage profile of the distribution system. But for heavy reactive power loads network reconfiguration and for heavy active power loads capacitor placement can not effectively reduce power loss and enhance voltage profiles in the system. In this paper, an hybrid approach that combine ne...

in this paper, a multi-objective reconfiguration problem has been solved simultaneously by a modified ant colony optimization algorithm. two objective functions, real power loss and energy not supplied index (ens), were utilized. multi-objective modified ant colony optimization algorithm has been generated by adding non-dominated sorting technique and changing the pheromone updating rule of ori...

Network Feeder Reconfiguration is the process of altering the topological structure of distribution feeders by changing the open/closed status of the tie and sectionalizing switches. In this paper, the Network Reconfiguration problem will be formulated as multi objective optimization problem with equality and inequality constraints. The proposed solution is based on optimization algorithms know...

Exploitation 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. The avoidance of such deadlocks will in general ma...

The dynamic reconfiguration of the interconnection network is an advanced feature of some multicomputers. It allows to reduce the communication overhead, improving the performance. In a previous paper [6], we presented a reconfiguration algorithm based on a cost function. It reconfigured the network in such a way that the original topology was preserved. However, that algorithm did not take int...

Software-defined networking (SDN) as a new paradigm for networking provides efficient resource reallocation platform in emerging cloud data center networks. The dynamic nature of cloud data center network's traffic, as well as the existence of big flows make it necessary to periodically reprogram the network through the SDN controller. Therefore, it is critical for network researchers to minimi...

Network virtualization and programmability allow operators to deploy a wide range of services over a common physical infrastructure and elastically allocate cloud and network resources according to changing requirements. While the elastic reconfiguration of virtual resources enables dynamically scaling capacity in order to support service demands with minimal operational cost, reconfiguration o...
