Noise-induced switching in dynamics of oscillating populations coupled by migration
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2023The problem of identifying the sources of switching in the dynamics of nonlinear coupled systems and their mathematical prediction is considered. We study a metapopulation system formed by two oscillating subpopulations coupled by mutual migration. For this model, parametric zones of mono-, bi-, and tri-rhythmicity with the coexistence of regular and ...

Maximizing SDN Control Resource Utilization via Switch Migration
Computer Networks, 2017Abstract Software-Defined Networking is challenged by load imbalance of distributed control plane that is statically mapped to data plane. In this article, we design a scalable control mechanism via switch migration locally to maximize control resource utilization, and we define this problem as Switch Migration Problem (SMP).

‘Migrating to a new virtual world’: Exploring MMORPG switching through human migration theory
Computers in Human Behavior, 2011Online gaming has become a popular leisure-time activity. In this study, we enlisted and adapted the Push-Pull-Mooring model, which analyzes human migratory behavior based on the Demographic Migration Theory, to study the game switching of gamers. Data was obtained via an empirical survey of 654 online gamers and then was analyzed using the Structural ...

On Controllers’ Utilization in Software-defined Networking by Switch Migration
2018This work presents a model to solve the switch migration problem in software-defined networking. This model is formulated as a mixed-integer linear programming, and compared against the static mapping approach. Two scenarios of homogeneous and heterogeneous controllers are evaluated. The experimental results show that the dynamic mapping enabled by the

Fractional switch migration in multi-controller software-defined networking
Computer Networks, 2019Abstract Mapping switches to controllers in multi-controller software-defined networking (SDN) is still a hot research topic. Many factors have to be considered when establishing this mapping. Among them are the load balancing and mapping stability.

Prediction-Based Switch Migration Scheduling for SDN Load Balancing
ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019Distributed architectures of the SDN control plane require a careful design for balancing the load among controllers. Solutions proposed for SDN load balancing usually use switch migration operations. However, an efficient switch migration means triggering the operation at the right moment, and judiciously choosing the migrated switch and the ...

Tunable haptotropic metal migration in fused arenes: towards organometallic switches
The Chemical Record, 2004AbstractTricarbonyl chromium complexes of naphthalene derivatives are synthesized by chromium‐templated [3 + 2 + 1]‐benzannulation and subjected to thermally induced haptotropic rearrangement experiments. Thermodynamic and kinetic parameters for the metal shift demonstrate the influence of the arene substitution pattern.
