Handover analysis of openflow-based mobile networks with distributed control plane
Strahil Panev,Pero Latkoski +1 more
TL;DR: A novel analytical approach is proposed to model the delay introduced by the handover-related OpenFlow signaling messages in SDN networks using multiple controllers and can facilitate the design of delay-constrained handover approaches in a mobile network with a target system throughput.

Analytical modeling of distributed network functions virtualization architectures and the impact of the distribution on the packet sojourn time
G. Ilievski,Pero Latkoski +1 more
TL;DR: In this paper , the authors make analytical models to calculate the network packet sojourn time in three different scenarios: classical NFV environment where all NFV elements are on the same location, distributed architecture of the data plane with centralized management and orchestration (MANO) environment, and distributed environment where every location has its own data plane and MANO elements.

Pareto-optimal resilient controller placement in SDN-based core networks
TL;DR: It is argued that it is not sufficient to look only at node-to-controller latencies but a controller placement should also fulfill certain resilience constraints especially for the control plane, and is provided an overview over related work and include different resilience issues in the controller placement process.

Improving the performance of load balancing in software-defined networks through load variance-based synchronization
TL;DR: A new type of controller state synchronization scheme, Load Variance-based Synchronization (LVS), is proposed to improve the load-balancing performance in the multi-controller multi-domain SDN net- work and achieves loop-free forwarding and good load- Balancing performance with much less synchronization overhead, as compared with existing schemes.
